Abstract: For sealing off overpressure valves of packaging containers, a small quantity of liquid sealant is introduced into a valve. To check whether such valve has been equipped with sealant, the sealant is heated, prior to introduction into the valve, to a temperature that is elevated compared with ambient temperature. After that the valve is checked for a temperature difference with a heat sensor, which causes valves not equipped with sealant to be rejected. The sealant is heated immediately prior to its application to a valve, in a nozzle delivering it.

Abstract: A known device for the atomization of liquids for injection valves including upper and lower fluid entry levels by which a tangential entry of air is provided into a space located below the injection valve in the direction of flow by which the generally occurring unevenness of distribution of fuel to different cylinders of an internal combustion engine is to be improved. The entry of the fluid from the upper and lower levels are oppositely oriented at the individual levels and thus produce two opposing swirl flows. The device is particularly suitable for injection valves for internal combustion engines.

Abstract: The invention is directed to a method of knitting a thick fabric, which is less in elasticity, less likely to deform, and firmer than a conventional fabric. The method is performed by using a flat knitting machine possessing a transfer lock capable of selecting and guiding the knitting needles to the loop transfer track or loop receiving track within the same phase as at least one knitting lock capable of selecting and guiding the knitting needles to three positions of knit, tuck and welt.

Abstract: A hydraulic system having a pressure generator which is protected against destructive overload. The hydraulic system has a pulsating feeding pressure generator, such as a piston pump, which feeds pressure fluid at high pressure into a damper chamber of a housing. A throttle body having a throttle bore is disposed on the outlet side of the damper chamber. For producing the protective effect, the damper chamber is preceded by a rupture disk communicating with the outlet. The throttle body suitably has a thin-walled portion, embodied as a rupture disk, in which the throttle bore is located. The embodiment described is advantageously usable in hydraulic systems in which pressure fluids are pulsatingly fed at high pressures.

Abstract: A fuel distributor for fuel injection systems of internal combustion engines has a distributor housing having a plurality of location holes, connected to each other by a fuel supply line, for accommodating electromagnetically actuated fuel injection valves, a hold-down firmly clamped on the distributor housing, for fixing the fuel injection valves in the location holes, and fixing means for fixing the distributor housing to the intake manifold of the internal combustion engine. For the noise decoupling of the fuel distributor from the adjacent add-on pieces, a noise-decoupling flat gasket is placed between the distributor housing and the hold-down on the one hand and the fixing means are formed by rubber-metal elements on the other hand.

In such an apparatus, an at least one intermittently operative coupling is provided to delay and/or stop the relative motion of the adjusting element relative to the coupler.

Abstract: A multi-circuit brake system having an anti-skid and traction control device for non-delayed, driver-activated braking. The multi-circuit brake system has a self-aspirating pump, which in case of traction control operation aspirates pressure medium from a pressure medium reservoir via an aspirating line and a main brake cylinder. A valve assembly in the brake line of the non-powered vehicle wheel is switched to maintain pressure in this case. A valve assembly, open in case of traction control operation, is located in the aspirating line. An auxiliary brake line with a pressure-controllable valve assembly originates at the aspirating line on the side towards the pump, when the valve assembly in the aspirating line is open, brake pressure generated by the driver by activating the main brake cylinder can be supplied to the wheel brake of the non-powered vehicle wheel. The invention is particularly suited for motor vehicles.

Abstract: A vehicle brake system having a pump drivable via pressure from the master brake cylinder, a reservoir fillable by this pump, and an electrically controllable valve which, in traction control operation, pressure fluid from the reservoir can be delivered to an inlet of the return pump. Via the pressure fluid from the reservoir, this return pump generates pressure for the wheel brakes of the drivable wheels.

Abstract: A fuel injection pump for internal combustion engines is proposed, in which to attain particularly quiet operation of an engine that is operated with direct injection, the fuel delivery is subdivided into a preinjection and a main injection; this injection is attained by annular groove, coinciding with one another, on the pump piston and pump cylinder, and a connecting groove connecting the coinciding annular grooves with a relief opening. After a partial stroke in the region of coincidence of the annular grooves with one another, the communication with the relief opening is interrupted again. The preinjection quantity can be kept particularly small here, with a short interval between the preinjection and the main injection; in combination with a two-spring-holder injection valve, this particularly small preinjection quantity can be kept constant to a great extent even at varying engine speeds, to attain an optimal reduction in combustion noise at various engine speeds.

Abstract: A fuel injection device for internal combustion engines has a fuel distributor which bears a plurality of connection pieces with radially projecting locking elements, and has a plurality of fuel injection valves, which are designed as so-called top-feed valves and are inserted fluid-tightly into the connection pieces. Provided to hold the fuel injection valves in the axial direction and to secure the fuel injection valves against rotation in the circumferential direction there is in each case a connecting member which engages in a circumferential groove in the valve casing and engages over the locking elements. In addition, the connection member has a fixing element which engages positively, at least in the circumferential direction, around a shaped element which is provided on the valve casing at a defined position.

Abstract: An air-measuring device for measuring the air mass taken in by an internal combustion engine which has a main flow channel, having a venturi section, and a temperature-dependent measuring resistor arranged in a bypass channel, the bypass channel opening upstream and downstream of the smallest flow cross-section of the venturi section in the direction of flow, in order to reduce the noise component in the measurement signal of the measuring resistor a channel region with an inlet and outlet opening is formed in the bypass channel, which channel region accommodates the measuring resistor in a central portion. The channel region is designed in such a way that the ratio of the flow cross-section of the central portion to the smallest cross-section of the venturi section is from 1:8 to 1:25 and the ratio of the cross-section to the cross-section of the inlet and outlet opening is in each case from 1:1 to 1:2.

Abstract: A throttle in a hydraulic system having a cross section which varies as a function of fluid flow in the hydraulic system. A throttle restriction includes a bore with a wire end segment extending in the bore that reduces the cross section of the bore. The wire end segment has an end face, facing counter to the pressure fluid flow, on which flow forces are operative. The flow forces are capable of positively displacing the wire end segment out of the bore counter to a spring restoring force. The throttle can for instance be used in the hydraulic brake systems in which peaks in volumetric flow and pressure are to be reduced. The throttle can also be used wherever self-cleaning of the throttle restriction is desired.

Abstract: A structurally simplified brake system which increases its functional reliability. The brake system has a brake pressure line extending between a master brake cylinder and a wheel brake. A shutoff valve is connected in parallel with a pressure limiting valve disposed in the brake line. A high-pressure pump toward the wheel brake side is capable of feeding pressure fluid into the line when the shutoff valve is closed. If a response pressure of the pressure limiting valve is exceeded, the pressure fluid can be diverted back to the master cylinder. The shutoff valve has a valve seat toward the wheel brake and a closing member toward the master cylinder which closing member is capable, by the action of a magnetic force on an armature of engaging the valve seat. A compression spring is disposed between the armature and the closing member and in the valve closing position exerts a closing force, adapted to the response pressure, upon the closing member.

Abstract: The invention relates to an apparatus for measuring a torque, conducted through a rotatable machine element, by means of fork-shaped transmitter levers including tines which are connected with two parts which, when a torque is transmitted, resiliently rotate in relation to each other, and the fork handle of which is hinged on a transmitter ring, so that the relative rotation between the two previously mentioned parts generates an increased axial movement of the transmitter ring, which is detected as a measurement of the torque. To prevent an overload on the measuring device and breakage of its components in case of impermissibly high torque shocks, stops are provided which limit the relative rotation of the two parts which rotate in relation to each other during the transmission of torque to a value which corresponds to the maximally permissible stress on the material of the measurement apparatus.

Abstract: A bistable solenoid for use with a knitting machine. The bistable solenoid includes an enclosure made of magnetic material which includes bearing surfaces at opposite ends. A plunger having a central region made of magnetic material and outer end regions made of non-magnetic material is movable within the enclosure for operation of a cam of a knitting machine. The movable plunger is controlled by axially aligned permanent magnets which are spaced from each other by a yoke. The permanent magnets are sandwiched between magnetizable coils which move the plunger toward the coil that is excited. The plunger is spaced radially from the coil's magnets and bearing so that very little wear is brought about during use in operating the cam of the knitting machine.

Abstract: A hydraulic engine valve control having a reservoir chamber, which is assigned to a pressure chamber of a valve tappet and has a reservoir piston, which at the same time serves as a valve by which the reservoir chamber can be disconnected from the pressure chamber. The reservoir piston is displaceable out of its position of repose into its reservoir function by a hydraulic control device that cooperates with a magnet valve. In this process, it is also attained that a plurality of valve control units of one internal combustion engine can be controlled via a single magnet valve, if their various control times do not overlap.

Abstract: A detachable intake neck connection for a pump which prevents aspiration of air into the hydraulic pump if a suction line is missing. The hydraulic pump has a first neck bore that, communicates with a suction chamber, which tightly receives an intake hose nipple of a suction line. The pump has a second neck bore for a pressure line, this second bore communicates with a pressure chamber. A connecting bore 31 that communicates with the pressure chamber of the pump begins at the neck bore for the intake hose nipple and is tightly closed by the intake hose nipple introduced into the neck bore. If the intake hose nipple is missing, the pressure chamber of the pump is short-circuited to the suction chamber through the connecting bore. A buildup of pressure in the pump and hence pumping of air is therefore precluded, the hydraulic pump is usable for instance for hydraulic vehicle brake systems, in which for safety reasons, the aspiration of air into the brake system must be prevented.

Abstract: An electromagnetically actuatable valves, including an adjusting bush pressed into a flow bore of a core of a coil in order to adjust a spring force of a restoring spring. The novel adjusting bush includes at least two longitudinal beads, extending in the direction of the longitudinal valve axis on its circumference that protrude past a jacket of the adjusting bush in the radial direction. The transitional region between the jacket and each of the longitudinal beads is embodied as rounded, at least in the direction of the longitudinal valve axis. Thus when the adjusting bush is pressed into the flow bore of the core, the production of chips at the adjusting bush and flow bore is prevented. The adjusting bush is especially well-suited for injection valves of fuel injection systems in internal combustion engines.

Abstract: A spring strut including a work cylinder with a slider in the work cylinder. Electrical contacts are applied on the slider and cylinder and in an inward stroke, a first electrical loop, which extends via the slider, is electrically closed and a second electric loop is broken. In an outward stroke, the second electric loop is closed via the slider, and the first loop is opened. Thus, with the aid of an electrical circuit, it is simple and easy to recognize whether the work cylinder is operating in an inward or in an outward stroke.
