A magnet valve is installed by a method in which the fully machined valve member is locked in a receptacle of a fixed installation device. A magnet plate and a spacer plate are mounted on a receiving mandrel. The magnet plate, spacer plate and valve member are pressed against the receptacle, then the magnet plate and the spacer plate are displaced relative to the valve member, and the armature is secured to the receiving mandrel of the valve member in such a way that the armature then rests on the magnet plate.

Method for installing a magnet valve

A solenoid-valve-controlled fuel-injection pump for internal combustion engines, in particular diesel engines, has a solenoid valve, whose valve needle separates a high-pressure region from a low-pressure region, i.e. connects the high-pressure region and low-pressure region, in the pump housing, via a valve seat; the injection period being controlled by the opening of the solenoid valve. In addition, a low-pressure compensating piston situated in the low-pressure region is provided in order to compensate for pressure fluctuations in the low-pressure region. The exceptional feature is that the low-pressure compensating piston, which is positioned coaxially to the solenoid-valve needle, takes the form of a component part that is separate from the solenoid-valve needle. This ensures that the solenoid valve is opened unhindered and as rapidly as possible by the opening force exerted on the solenoid-valve needle by the electromagnet.

A fuel injection pump for internal combustion engines which has a moving part supported in a housing bore and on its jacket face on one side, has an exit opening that is under high pressure, and whose bearing is improved by virtue of the fact that on the jacket face of the part or in the wall of the housing bore, at least one pressure compensation is provided. The compensation face is connected to a high pressure source, is disposed on a side of the jacket face of the part which side is remote from the exit opening, and is continuously covered by the wall of the housing bore. As a result, a compensation of the pressure action by means of the pressure field prevailing in the region of the exit opening occurs so that an improved, less damage-prone bearing is produced with a greater high pressure tightness of the moving part.
