Abstract: A method operating a braking system to prevent or overcome glazing of the brake linings. The brake system has a friction-affected service brake and a wear-free auxiliary brake. A brake value, for instance vehicle deceleration, can be specified to the brakes by a brake value transducer. On the specification of the brake value transducer signals, a control unit triggers the brakes; it detects and evaluates signals characterizing the braking action. Upon a request for braking, the control unit preferentially triggers the auxiliary brake. If the brake value transducer signal level is high, it additionally switches on the service brake. The control unit detects the number of braking events of the service brake and their intensity (duration, action, etc.). As a function of these data, the control unit detects a threatening danger of glazing or glazing that has already begun and triggers the service brake exclusively.

Abstract: A device for transporting articles from a plurality of dispenser machines to a packaging machine including at least two delivery belts, a delivery device assigned to a furnishing device with furnishing places. Drivers that transfer the furnished articles to receiving cups of a conveyor apparatus of a packaging machine. For transferring the articles furnished to two furnishing places to the conveyor apparatus at a single transfer point, some of the drivers are disposed fixedly relative to the conveyor, and the others are disposed displaceably, transversely to the conveyor direction on the delivery device. The drivers are connected to bars, which extend transversely to a pair of conveyor chains. Stationary guide rails transmit the additional transverse motion to the displaceable drivers.

Abstract: An air brake system having an anti-skid assembly is proposed, which is provided with a switch assembly comprising a relay valve and a magnet valve assembly. In the vicinity of the switch assembly there is a special line, with which the control pressure can be short-circuited with the brake pressure in the pressure maintenance phase. This largely prevents lagging of the brake pressure relative to the control pressure. The air brake system is intended for utility or commercial vehicles.

Abstract: An electromagnetic rotation control element, for an idle rotation control device for internal combustion engines, include a magnet housing with at least two magnetic poles and with a rotating armature with an even number of pole pieces that cooperate with magnetic poles, and with a restoring spring that acts on the rotating armature. For the purpose of increasing the influencing possibilities for achieving the required characterizing line of the rotation control device, each pole piece is divided into two pole piece sections, located next to each other in the axial direction and having differently formed contour lines. The one contour line has the shape of an arc of a circle, while the other contour line increasingly deviates from the one pole piece end to the other from this arc of a circle shape.

Abstract: A hydraulic dual-circuit brake system for motor vehicles comprising an antilock system (ABS) and an anti-spin control system (ASR) a four-duct hydro unit with control valves and a return pump with two separate pump elements for each brake circuit. An active piston storage unit is provided to supply brake pressure during ASR operation and each brake circuit containing at least one drive wheel is separable from a main master brake cylinder by means of a stop valve. The piston storage unit replaces the usual storage chamber at the input of a dual pump element provided for the brake circuit of the drive wheels and is activated at the beginning of anti-spin operation and is thereby filled with brake fluid from the brake fluid container. The piston storage unit is then de-activated such that the storage spring becomes operative and brake fluid is supplied via the storage piston into the pump element connected to the piston storage unit.

Abstract: A pressure switch valve which briefly raises a pressure during switching of the valve. The pressure switch valve has a cylindrical chamber with a first ball that engages a valve seat of an inflow conduit. A second, spring-loaded ball is supported on the first. Both balls are longitudinally movable with slight radial play in the cylindrical chamber. An outflow conduit branches off from the cylindrical chamber at one point in such a way that upon switching of the valve, a normal plane containing the spherical center of the first ball toward the valve seat and extending at right angles to the longitudinal axis of the chamber does not reach the mouth cross section of the outflow conduit until a corresponding normal plane of the second ball toward the spring has already exited from the mouth cross section.

Abstract: An active control precision damping table supported by air springs. Level displacement and vibrations of the table are detected by a sensor or sensors, and sensor outputs are fed to a variation adder which carries out an adding operation on one of the sensor outputs and an inversion signal produced by inverting the other sensor output 180 degrees. The adder outputs results of the operation to a drive circuit, which in turn outputs a drive signal to a control valve. The control valve is operable in response to the drive signal to adjust air pressure in pressure vessels of the air springs.

A carrier plate and pivot plates function to disconnect the nut so that a hand-operated lever can be used to manually operate the brake.

Abstract: A fuel injection device for injection internal combustion engines comprising a main injection plunger and a preinjection plunger, which is arranged coaxially with the latter and separated from the latter, and has a smaller diameter.

Abstract: A tank vent valve for the metered admixing of volatilized fuel to the fuel/air mixture of an internal combustion engine has a valve housing with inflow and outflow sockets, between which is arranged an electromagnetically operable seated valve, which is spring loaded in the closing direction by a valve closing spring. For the simple design of the tank valve, the valve opening of the seat is arranged as a ring gap nozzle in the return yoke of the electromagnet, and the valve double seat which acts in conjunction with the valve member and which surrounds the ring gap nozzle is arranged on that side of the return yoke which faces the inflow socket. For setting the stroke of the valve member, the hollow cylindrical magnet core of the magnet housing can be threaded by means of an adjusting thread in the magnet housing. Supported on the magnet core is a valve closing spring, which loads the valve member which is formed by the armature of the electromagnet, in the closing direction.

Abstract: An adjuster for a throttle device of an internal combustion engine in which a switch tappet is guided in an actuating tappet in such a way that external forces are not exerted upon it, which prevents any problems to the switch performance. The adjuster is embodied such that the switch performance is easily adjustable and is protected against external influences. The adjuster has an actuating tappet, formed of a guide body and a switch socket, in which a switch is disposed. The switch socket is displaceably supported in the guide body with a guide shoulder counter to the force of a restoring spring and it guides a switch tappet, which is aligned with the switch and which is threaded to a variable depth into the switch socket in order to adjust the switch point. Any external forces act upon an actuating body supported in the switch socket. The adjuster is used to adjust the position of a throttle device in the intake tube of an engine.

This embodiment of the valve is particularly well suited for injection valves of fuel injection systems.
