Abstract: A magnetic valve that is switchable in two directions is proposed. The valve comprises an armature, which is firmly joined to a valve body; at least two magnetic coils disposed in one plane and having ferromagnetic cores inserted in them; and two pole bodies, which are joined to the cores and with them belong to the electromagnetic circuit, and acts on the oppositely located flat sides of the armature. Permanent magnets are inserted into the pole bodies in such a way that the operative surface area of the pole bodies is divided into a number of zones, each having a homogeneous magnetic orientation in which the number of zones is equal to the number of magnetic coils.

Abstract: A pressure regulating device is proposed, which serves to regulate the fuel pressure in a fuel injection system for internal combustion engines. The pressure regulating device includes a pressure regulating valve which has a valve diaphragm fastened in a valve housing and defining a fuel chamber which communicates via an inflow opening with a fuel distributor line. Protruding into the fuel chamber is a valve seat body joined to the valve housing, on one end of which body a valve seat is formed and the other end of which is embodied as an outlet pipe that passes through the wall of the fuel distributor line. The fuel distributor line is formed of two shell halves inserted one inside the other, of which the first shell half has a tub-shaped end into which the pressure regulating valve is inserted and with which it is securely fastened.

Abstract: A device for transmitting of binary data between a mobile data carrier (10) and a stationary station (11) is provided with a first resonance circuit (13) in the stationary station (11), whereby a switchable field effect transistor (25) is parallel switched to its condenser (17) by means of a switching pulse sequence, a second resonance circuit (12) in the data carrier (10) which is at least conductively coupled for a short time with the first resonance circuit (13). For the purpose of enlarging the inductively to be bridged distances between the resonance circuits (12,13) of data carrier (10) and stationary station (11) without impairing the operating safety during the data transmission the resonance circuit (13) in the stationary station (11) is designed in such a manner that its resonance frequency is about equal to the switching pulse sequence.

Abstract: The ignition system of a five-cylinder gasoline engine utilizes two ignition coils, each serving two cylinders which are fired at instants of the firing sequence which are separated by the firing of one of the cylinders served by the other of these ignition coils. A third ignition coil fires only the remaining cylinder. The sparkplugs of two cylinders fired by the same ignition coil are connected through oppositely poled diodes. This arrangement avoids circuit closing sparks when either of the twin primary windings of the ignition coils serving two cylinders is turned on. There are thus five separate primary windings and only three separate secondary windings, and the former are turned on and off by individual electronic switching circuits triggered in sequence by individual pulse generators responsive to a magnet on a single rotary disc.

Abstract: In an electric device, a cable-supporting element for receiving an electric supply cable is formed of two disengagably-connectable portions, of which the first portion is formed with an extension inserted into a hole of a respective shape, formed in the cover of the housing of the electric device. The first portion is then displaced relative to that hole so that a projection formed on the extension, overlaps an inner edge of the recess and engages the latter. The second portion provided with a filling piece is then set onto the first portion so that the filling piece fills, together with the remaining part of the extension, the hole. The first and second portions are then locked to each other.

Abstract: A fuel injection pump for internal combustion engines is proposed, which is embodied as a radial-piston/distributor pump, having an axially fixed and rotationally driven distributor, on the end of which that is remote from the drive and protrudes freely out of the distributor cylinder guiding the distributor an annular slide is disposed, which can be both rotated and axially displaced by means of adjusting drives. Both the quantity adjustment and control of the instant of injection are effected in a electrically controlled manner by relief openings provided on the distributor and control openings which are provided on the annular slide. All of the foregoing can be effected precisely on the end of the distributor which is free of moment.

Abstract: A fuel injection nozzle for internal combustion engines which has a valve needle loaded in the closing direction and is radially guided and supported in an axially displaceable manner within a nozzle body. The movement of the valve needle is effected in the opening and closing directions in a selectively variable manner, a spring-loaded supplementary mass which performs a dual function being disposed in the nozzle interior. In the opening direction of the valve needle, the supplementary mass is displaced along with the valve needle, while in the closing direction the two elements are separated. The supplementary mass influences the movement of the valve needle both inertially, as the result of its mass, and by effecting a speed-dependent damping, as the result of the positive displacement of a fluid from damping chambers, the whole being adapted to a constant or variable throttle disposed in the fuel inlet conduit.

Abstract: An electromagnetically actuatable valve is proposed, which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing, a core, a magnetic coil and a cylindrical armature which is connected via a rod-like connecting part having a smaller cross section than the armature with a valve closing member embodied in the form of a ball. The valve closing member cooperates with a valve seat provided in a valve seat body. The radial guidance of the armature is effected by a narrow annular disk. The valve closing member is radially guided only by the valve seat in its closed position and by a stop in its open position. Downstream of the valve seat fuel guide bores lead into a preparation bore in the form of a blind bore, which has a diameter of approximately 1 mm.

Abstract: A fuel injection pump has a stepped piston operatively disposed in a stepped bore so as to define a first pump work chamber and a second pump work chamber. A constant fuel injection quantity (h.sub.FE) is pumped to the second work chamber per pump piston stroke, and a variable fuel injection quantity is pumped out of the first pump work chamber to a common distributor groove which actuates delivery of the fuel to individual injection lines.

Abstract: An anti-skid brake system and anti-drive-slip system having a master cylinder, at least one inherently safe closed brake circuit which includes anti-skid valves and wheel brakes, a booster cylinder associated with the master cylinder and in which a booster piston is displaceable, a pressure supply apparatus, a valve connected thereto, which is actuatable by means of a brake pedal for controlling brake pressures. A locking piston cylinder connected to the control valve, a sensing piston, which is coupled to the brake pedal and which passes into the locking piston cylinder, and a change-over valve assembly. This change-over valve assembly is embodied such that for normal braking operation, it connects the booster cylinder with the control valve. If there is a danger of skidding, or wheel lock, this change-over valve assembly disconnects the booster cylinder from the control valve and connects it to a return line in order to relieve pressure and reduce the braking pressure.

Abstract: A hydraulic control arrangement for regulating a lifting device in an agricultural vehicle has a proportionally operating regulating directional valve which includes a blocking unit, a control slider controlling said blocking unit and connected with a throttling valve so that its throttle slider during lifting operates as a pressure compensation valve and during lowering as a pressure reducing valve, and a spring associated with the throttle slider is only insignificantly stronger than the regulating spring in an adjusting device of an adjusting pump, so that during actuation of the throttle slider depending upon the high load pressure of a parallel-operating second hydromotor, the pressure differential required for the lifting stream at the control slider and the pressure differential acting during lowering in the first control conduit remain substantially constant.

The fuel supply line has an elastic wall section, with which is connected a rigid wall section and on which are fastened the supports. The elastic wall section is elastic to the extent that it damps the pressure pulsations of the fuel in the fuel supply line, whereas the rigid wall section assures the required rigidity of the fuel supply line.

Abstract: A brake system having a master cylinder for generating brake pressures in at least one closed brake circuit (I, II) and having an associated brake booster including a booster cylinder, a displaceable booster piston having a piston rod oriented into the master cylinder and a tappet arranged to plunge into the booster cylinder by means of a brake pedal and be displaced counter to the booster piston and is equipped with a brake valve connected to a pressure supply device, which brake valve is controllable by means of the relative movement of the tappet with respect to the booster piston. The brake system may be modified to become an anti-drive-slip apparatus via brake pressure maintenance valves built into the brake circuits (I, II), as well as a 3/3-way valve, by means of which pressure medium can be sent directly from the pressure supply device for exerting boosting action on the booster piston into the booster cylinder.

To supply eight-cylinder engines or multi-cylinder engines at high rpm or to realize a pre-injection with large angular intervals, a radial piston pump is proposed the pump pistons of which are firmly connected to the roller shoes driving the pump pistons, and the rollers carried by the roller shoes roll off simultaneously on a first cam track of a first, outer roller ring and on cam tracks of second, inner roller rings and are thereby compulsorily guided between the cam tracks of the two roller rings.

Abstract: To prevent damage upon removal of a locating templet used in positioning a plate-like semiconductor on a support carrier (2, 14), for example a base plate (2) of a transistor housing or a metallized surface of a ceramic insulator (14), the locating templet (9) is made of solderable material, positioned with respect to the carrier structure by interengaging projection-and-recess elements (10, 10', 11) and soldered to the carrier in one soldering operation, the templet remaining on the carrier structure and forming part of the semiconductor element. If the carrier structure is the metallized coating of a ceramic, the templet may then be used as a terminal connection point for a connection or bonding wire connected to an internal portion of a connection pin extending through the housing of the semiconductor structure.

Abstract: A method and an apparatus are disclosed for determining the flow rate of a flowing medium such as the amount of air supplied to an internal combustion engine. The apparatus includes at least one temperature-dependent resistor arranged in the flowing medium. For this purpose, an arrangement is provided which applies a quantity dependent on at least the flow rate to the temperature-dependent resistor. The method includes the step of abruptly reducing the flow rate dependent quantity to a value such as approximately zero in the presence of a flow-rate value lying below a predeterminable threshold value. Because the reduction takes place only for a predetermined period of time, normal operation will be resumed automatically when the flow rate rises again. A hot-wire air-flow sensor is arranged in the intake pipe of an internal combustion engine and the output signals thereof are a measure of the amount of air inducted by the internal combustion engine.

The electromagnet includes an inner core of soft-magnetic material, which is surrounded by a magnetic coil. An outer core at least partly surrounds the magnetic coil and has an outer pole located in the same plane as an inner pole of the inner core. On one side of the magnetic coil, between the inner core and the outer core, there is a first annularly embodied and radially magnetized permanent magnet, and on the other side of the magnetic coil there is a second annularly embodied and radially magnetized permanent magnet. Facing the poles, there is an armature, which at one end is joined to a valve needle that has a valve body cooperating with a valve seat, and on its other end forms a first working air gap with the outer pole and a second working air gap with the inner pole.
