ABSTRACT:
An electrically controlled valve which is used for controlling the opening area of a connection between a high pressure chamber and a low pressure chamber. The valve is embodied as a solenoid valve and has a valve seat on which a deflection point is provided downstream of a downstream edge of the valve member in the through flow direction. By means of a flow deflection, the fluid passing through is conveyed against an annular face provided on a valve member. The resulting pressure accelerates the opening of the valve. The solenoid valve is designated for use in fuel injection pumps in motor vehicles.
