    Abstract: In a method for controlling the demagnetization phase of electromagnetic devices, particularly electromagnetic valves in combustion engines, the exciting current i=i(t), starting from a high holding current value, is decreased not to zero or even to a negative value, but to a value in the positive range below the holding current. Because of the characteristic current and/or voltage values which accordingly occur in the excitation circuit, the start of the opening and the end of the opening of the valve needle of the electromagnetic valve can be determined in a particularly precise manner and can be taken into account for an optimal influencing of the manner of operation of the combustion engine (FIG. 3).

    Abstract: For controlling high-pressure phases during the stroke of a pump piston of a fuel injection pump, magnetic valves are also used, which are built into relief lines of the pump work chamber of such fuel injection pumps and which with the instant of closure of the relief line determine the injection onset and with the instant of reopening of the relief line determine the end of injection and hence the injection quantity. Such valves must be capable of switching rapidly, in view of the high rpm of internal combustion engines, yet must be as small as possible and use the least possible energy. By using a piston slide which in the closing state is balanced in pressure on the high-pressure side, and by relieving the chambers defined on the face end by the piston slide, a fast-switching, recoilless magnetic valve is obtained, which is opened by a restoring spring when the electromagnet is in the currentless state. This makes the use of the magentic valve in combination with electrically controlled injection pumps particularly advantageous.

    Abstract: A fuel injection pump, preferably for internal combustion engines operating by the Otto method, having a pump work piston driven to reciprocate and rotate simultaneously and defining two mutually independent pump work chambers, is proposed. The first pump work chamber pumps fuel into the combustion chamber of the engine that is in a state immediately prior to ignition, while the second pump work chamber pumps fuel into the combustion chamber operating offset from the other by 360.degree. of crakshaft angle. To this end, two distributor openings are disposed in the jacket face of the pump work piston, offset by 180.degree. from one another and each communicating with a different one of the pump work chambers.

    Abstract: A magnetic valve used for fluid control includes a valve housing, having a magnetic coil surrounding a core, and an armature, which is joined to a valve closing element which cooperates with a fixed valve seat. An end on which a collar is embodied, the valve closing element protrudes into an interior of a spring housing, which is slidably disposed counter to the force of a counterspring. A first bent end of an angle element is supported on a cover of the spring housing, while a second bent end grips the collar from behind and protrudes through a bottom opening of the spring housing. In the open position of the valve closing element, the second bent end is spaced apart from the collar by a distance a. In the valve closing element there is a compensation bore leading to the interior of the spring housing. After actuation of the magnetic coil, the armature displaces the valve closing element toward the valve seat counter to the force of the restoring spring. Only with a delay does a fluid pressure build up in the interior which displaces the spring housing toward the housing stop, thereby stressing a supplementary spring. When the magnetic coil excitation is interrupted, the forces of the restoring spring and of the supplementary spring act in common in the opening direction of the valve closing element, thereby effecting a rapid opening.

    Abstract: The magnetic valve for fluid control in a fuel injection nozzle includes a valve housing having a magnetic coil mounted on a core of ferromagnetic material and an armature, which is connected to a valve closing element cooperating with a fixed valve seat. After the excitation of the magnetic coil is interrupted, the valve closing element is moved toward a stop tappet by the force of a restoring spring and by the fluid pressure engaging the valve closing element. The stop tappet is supported such that it is displaceable in the opening direction of the valve closing element, counter to the force of a second spring. As a result, a large flow cross section is available for the fluid between the valve seat and a closing body of the valve closing element and a rapid pressure drop is made possible. If the fluid pressure drops below a predetermined level, then the additional spring displaces the stop tappet and hence the armature and the valve closing element into a position in which the flow cross section and the air gaps provided at the armature are decreased, thereby assuring rapid closure of the magnetic valve when the magnetic coil is excited.

    Abstract: A rotary positive-displacement pump in which the vane or vanes separating the chambers are locked in the inner dead center point after a certain outlet pressure has been attained, in order to shut off the pump. A corresponding locking apparatus has a detent which assures that each vane is locked in a form-locking manner in the position which shuts off the pumping action. Preferably, the locking apparatus has an overstroke step by means of which it is assured that each vane is constantly held at an increased distance from its sliding surface so that friction and impact noises are positively avoided.

    Abstract: Rapid movement of the gas pedal initiates a shifting operation to the next higher or next lower gear depending upon whether the speed of the gearing lies above or below a predetermined speed range. The speed range extends from a first to a second predetermined speed. Both the width of the range and the actual values of the first and second predetermined speed are automatically adjusted as a function of the throttle valve position and the then-present gear. If the gas pedal is not activated but the gear speed is less than a predetermined first threshold speed, an automatic down-shift takes place. Up-shifting can only occur when the speed of the gearing exceeds a minimum up-shift speed. Engagement and disengagement of the clutch is controlled and may include jolt limiting. The engine speed is limited during gear shifting.
