摘要： A differential pressure valve is proposed for a fuel injection system of an internal combustion engine. The differential pressure valve includes a diaphragm embodied as the movable valve element, which separates two chambers from one another. A fuel supply line discharges into one chamber and a valve seat carrier provided with a valve opening protrudes into this chamber. This chamber also houses a filter element and a valve spring is disposed coaxially with the valve seat carrier between upper and lower spring plates. The filter element is disposed such that a subsequent change in the tension of the valve spring is also possible. To this end, the filter element can engage the upper spring plate on one side in a sealing manner and on the other side can be supported in a sealing manner in a groove of the wall of the chamber (FIG. 1). In order to assure the free mobility of the filter element, it is provided with an elastically deformable area. As shown in FIG. 2, the filter element may, however, also engage the lower spring plate in a sealing manner and with its other end surroundingly engage the spring plate with as little play as possible, to thereby form a labyrinth seal.

摘要： 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. If the fuel distributor is made of plastic, the rubber-metal elements are preferably made of a clamping bolt, a metallic distance sleeve and a resilient sleeve, which are arranged coaxially in the sequence mentioned and pass through through holes in the distributor housing and hold-down.

摘要： A positioning apparatus including a positioner, a restoring suspension means, a servo drive and an actuator, the position of which determines the power of a driving engine. The restoring suspension means assures that the actuator is always in a precisely definable position regardless of any other spring. The restoring suspension means may include a plurality of integrally cohering restoring springs. Satisfactory operation of the apparatus is assured even if one of the restoring springs should fail. The servo drive is embodied such that in the event of an electrical defect the engine operates at an intended speed (rpm). The apparatus is particularly suitable for motor vehicles in which the engine rpm is to be regulated precisely in idling via a throttle valve.

摘要： In known devices, the fuel injection valves, disposed in individual receiving bores, are retained individually with clamping shoes, and electrical contact is provided by individual electric plugs. The novel device is intended to assure that all the fuel injection valves are retained and provided with electrical contact simultaneously. The fuel injection valves inserted into receiving bores of a basic body are retained in common in the receiving bores by means of a contact-making outlet strip, slipped onto the basic body, and are electrically connected in common by means of electrically conductive contact elements. The entire compact device can be fastened as a unit to the engine and electrically connected, via a connection plug to an electronic control unit for trigging the fuel injection valves. The device makes adaptation to various engine types possible.
