Abstract: A high-pressure pump having a pump element a pump piston driven in a reciprocating motion and defining a pump work chamber into which fuel is aspirated from a fuel inlet during the intake stroke via an inlet valve, and from which fuel is positively displaced via an outlet valve during the pumping stroke. The inlet valve has a valve member which with a sealing face inclined relative to its longitudinal axis, cooperates with a valve seat disposed in a valve housing when the sealing face of valve member is lifted from the valve seat, a flow cross section between the valve member and the valve housing is opened between the fuel inlet and the pump work chamber. In the opened state, a region having the smallest flow cross section between the valve member and the valve housing is disposed downstream, of the sealing face of the valve member.

Abstract: A fuel injection device for internal combustion engines, having a fuel injection pump, which can be inserted into a housing of the engine and is axially clamped together with a fuel injection valve by means of a clamping sleeve. The valve, with an end remote from the pump, protrudes into a combustion chamber of the engine. A fuel supply line to the fuel injection pump feeds into an annular chamber encompassing the clamping sleeve and, via through openings in the clamping sleeve and inlet conduits in the pump housing, the valve can be connected to a pump working chamber of fuel injection pump. According to the invention, the fuel filter in the inlet to the pump working chamber is constituted by the clamping sleeve, which has a multitude of filter openings for this purpose in its circumference wall, in the vicinity of the annular chamber.
