Abstract: In known equipment for injecting a fuel-gas mixture, the danger exists of an asymmetrical effect on the fuel stream from the delivered gas, with resultant poor mixture formation. The novel apparatus has a fuel injection valve, the injection end of which rests on a bearing face of the longitudinal bore of the valve holder. Between the injection end and the bearing, an annular gas conduit is formed, from which at least two gas gaps originate, having opposed gap openings discharging into the mixing line. The symmetrical delivery of the gas to the centrally injected fuel stream leads to the formation of a maximally homogeneous fuel-gas mixture. The embodiment of the apparatus is especially suitable for use in mixture-compressing internal combustion engines with externally supplied ignition.

Abstract: A magnet system for magnet valves for controlling liquids including an electromagnet and a permanent magnet that produces magnetic fluxes, the magnetic fluxes of which are oriented opposite one another in a working air gap formed between a free-floating armature and a magnet pole. To attain a course of the force of attraction acting upon the armature that becomes negative beyond a certain excitation of the electromagnet, and to reduce the trigger power for the electromagnet, a magnetic opposite pole is disposed on the side of the armature remote from the working air gap, forming a second working air gap, which is coupled to the magnet housing, optionally via a stray air gap, via a flow guide element annularly engaging the permanent magnet.

Abstract: A fuel injection pump having a speed governor which is housed in a pump body under a control pressure and which actuates an injection quantity control element, and a hydraulic injection timing mechanism which is connected with the pump body and which adjusts the start of injection (SB) to "early" with increasing pressure in the pump body, and to "late" with decreasing pressure. For the implementation of a load-dependent start of delivery (LFB), a governor sleeve of the speed governor governs in a load dependent manner, a relief throttle in the pump body, which, depending on the displacement setting of the governor sleeve, uncovers a varying cross-sectional throttle area to an outlet bore.

Abstract: A pressure valve, which is installed in the delivery line leading from a fuel injection pump to a fuel injection valve, and which has a valve closing member opening in the direction of delivery, which is provided with a return collar. To achieve uniform injection, particularly a uniform curve of injection at a given load plotted against the speed, the opening rate of the connecting cross-section at the valve closing member is controlled by the guide part being provided immediately adjacent to the return collar, which guide part has three excisions at its circumference. These excisions are bounded by a flow channel guiding the valve closing member and have a defined flow cross-section of equal size, which in total is of the order of magnitude of the cross-section of the delivery line.

Abstract: An improved separator outlet member for a pea sheller which includes a plurality of square passageways aligned side-by-side along the length of a base member. The peas are collected in the square openings as the pea sheller rotates and the peas drop onto a bottom plate spaced from the passageways from which the peas pass to a shaker for collection.

Abstract: A mass flow controller having a bypass portion provided in a body through which a large amount of gas is passed and a sensor portion, laid between a primary chamber which is an inlet of the bypass portion and a secondary chamber which is an outlet of the bypass portion, through which gas flows at a small flow rate proportional to the flow rate of the gas passed through the bypass portion and capable of measuring the total flow rate of gas by measuring the flow rate in the sensor portion. The body is partitioned by a bulkhead into a primary chamber and a secondary chamber. The primary chamber is provided with an inlet for gas inflow and the secondary chamber is provided with an outlet for gas outflow. The bulkhead is provided with a plurality of through holes for connecting the primary chamber to the secondary chamber, and bypass elements selected depending on the flow rate in the bypass portion are fitted in the through holes in the bulkhead.

Abstract: A cylinder-piston unit including a central valve having a valve shaft, on which two spring plates with a pre-stressed restoring spring are disposed. One of the spring plates is engaged from behind by a cross-sectional enlargement of the valve shaft which has a valve closing element. The cross-sectional enlargement is formed by a collar of the valve shaft. Another cross-sectional enlargement comprises a sleeve, which is longitudinally displaceably guided on the valve shaft. On the side remote from the restoring spring, the sleeve has an enlarged inner bore, with which the enlarged inner bore complementarily fits over a snap ring that engages the valve shaft. As a result, a form-locking connection is attained between the sleeve and the valve shaft that assumes that a preassembled valve component unit will be held together even if the snap ring breaks.

Abstract: A vibration motor having a disk-shaped stator containing a piezoelectric excitation system, a disk-shaped rotor aligned parallel to the stator and mounted on a driven shaft in a manner fixed against relative rotation, and a pressing element that presses the rotor and stator together axially. To assure free travel of the driven shaft when the motor is currentless, the pressing element is embodied as a force-transmitting element that changes shape as a function of temperature, for instance a compression spring of memory metal. In motor operation, the element is kept at a temperature above its temperature point for the shape change, and it is disposed such that the pressing force between the rotor and stator diminishes as a result of the shape change ensuing if the temperature drops below this temperature point.

Abstract: A hydraulic brake system with an anti-skid system (ABS) and traction control (ASR) for motor vehicles having a hydraulic unit with at least one control valve and a return pump with at least one pump element embodied as self-aspirating, which element is operative in the brake circuit containing the at least one driven wheel. To furnish brake pressure during traction control, a valve assembly is provided. For the sake of simplicity in the embodiment of this valve unit, it has not only a charge valve disposed in an intake line between the pump element and the brake fluid tank but also a reversing valve, incorporated between the master brake cylinder and the control valve and having three hydraulic control inlets and a restoring spring, of which one control inlet communicate with the outlet of the pump element, and the two control inlets counteracting this control element communicate with the valve inlet and outlet, respectively.

Abstract: An apparatus having a self-aspirating pump, with which, in a traction control mode, pressure fluid can be aspirated through an intake line from a pressure fluid supply tank of a master brake cylinder. Located in the intake line is a control valve that assumes its preferred blocking positoin and can then be switched into its open position by a pressure pulse generated by the pump, through a control line. This open position can be switched whenever a control valve, located in the brake line of the master brake cylinder, is switched by an electronic control unit of the control apparatus out of its preferred position thereby connecting the master brake cylinder to the wheel brake cylinders into another position, thereby carrying pump pressure to the control valve. Aspiration of pressure fluid from the supply tank is thus avoided upon pump startup with undesirable feeding. This prevents the production of noise from the pumping of pressure fluids into the master brake cylinder.

Abstract: A hydraulic dual-circuit brake system with an anti-skid system (ABS) and traction control (ASR) for motor vehicles has a four-channel hydraulic unit with control valves and a return pump with two separate pumping elements for each brake circuit. To supply brake pressure in traction control operation, an additional unit is provided having a charging valve for connecting a self-aspirating pumping element of the return pump to the brake fluid tank and a reversing valve disposed in the connection between this pumping element and the master brake cylinder. For a rapid buildup of brake pressure in traction control, given wheel brake cylinders requiring a large brake fluid volume, a reservoir is provided connected to the brake pressure supply circuit by a reservoir connection valve via the reversing valve.

Abstract: A multipin plug including plug housings which are connected in a floatingly movable manner in the horizontal and vertical direction to one central floor part of a receiving opening of the multipin plug so that offsets occurring between the first and the second electrically conductive contacting elements are compensated and damage is avoided. Such a multipin plug is particularly suitable for electrically connecting fuel injection valves to the multipin plug.

Abstract: An electrohydraulic valve control device for internal combustion engines in which a tappet volume for operating a valve piston arranged between an actuating cam operated cam piston and an engine valve can be reduced via a solenoid valve which is arranged in a drain passage. Arranged in this drain passage is a shut-off valve which is hydraulically actuated to open only when the valve piston has carried out a minimum stroke. This minimum stroke corresponds to a torque angle range of the camshaft in degrees of rotation during the opening actuation, in which, due to the shut-off valve, a control by the solenoid valve is not possible, whereby despite overlapping of engine valve opening times in a multi-cylinder engine, any overlapping of control times for the drain passages of individual engine valves, predetermined by the solenoid valve is prevented.

Abstract: An air pump assembly is disclosed which comprises an outer shell and an inner shell nested within the outer shell; the shells defining between them a housing into which is secured an air pump. The latter includes an air chamber having a solid base and a resilient pumping membrane; the pump further including valving unit in air communication with the air chamber, the unit being provided with an air deflation rod. The housing has an aperture capable of giving access to the flexible membrane to operate the pump. This housing is sized so that the air pump is held completely in it to protect it against outer shocks; the membrane being accessible from outside the outer shell through the aperture. The same outer shell is formed with an outwardly open recess into which the deflation rod is received; this recess being sized for the rod to be held wholly in it and be protected against outer shocks.

Abstract: A control device including a reversing valve, disposed in fuel lines into which a feed pump is introduced between a fuel supply tank and a suction chamber of a fuel injection pump, by means of which valve, to turn off an internal combustion engine operated with the fuel injection pump, the line connections are variable in such a way that the suction chamber communicates with the intake side of the feed pump and the compression side of the feed pump communicates with the fuel supply tank. As its valve member, the reversing valve has a slide, which carries first and second double-seat-valve closing bodies that cooperate with corresponding valve seats. The first and second double-seat-valve closing bodies form sealing elements which are detachably buttoned onto the slide that are made of an elastically deformable material.

Abstract: A rail support adjusting and fastening device according to the present invention is used in such a state that tilting of each of the rails and the gage of a track are briefly adjusted in advance by connecting members (cross ties and the like) for connecting parallel rails to one another when the track is directly laid onto a concrete bed as a direct fastened track.

Abstract: A magnet valve that serves to block off a fuel intake line to control fuel flow to supply a pump work chamber of a fuel injection pump with fuel, a closing element has a bore entering at the face end, which bore can be closed by a valve member under the influence of a closing spring. When pressure surges occur in one part of the intake line which is closed by the closing element and leading to the pump work chamber, instead of the closing element and the entire cross section of the intake line portion being opened, only the cross section of the bore is opened. Once it has been pushed open, this bore is rapidly closed again by the low-mass valve member, so that only small quantities of fuel can flow via the bore for pressure equalization.
