摘要： A high-pressure pump (1), which serves in particular as a radial or in-line piston pump for fuel injection systems of air-compressing, auto-ignition internal combustion engines, comprises a cylinder head (2) and a pump assembly (6). Here, the cylinder head (2) has a cylinder bore (4) in which a pump piston (5) of the pump assembly (6) is guided. Here, the pump piston (5) delimits, in the cylinder bore (4), a pump working chamber (12). Also provided is an inlet valve (20) which is integrated into the cylinder head (2) and via which fuel can be conducted into the pump working chamber (12). Metering of the fuel conducted into the pump working chamber (12) can be achieved by actuation of the inlet valve (20). Here, full charging of the pump working chamber (12) may take place. It is however also possible for partial charging of the pump working chamber (12) to be achieved by means of suitable actuation of the inlet valve (20).

摘要： The invention relates to a fuel injection device which is provided, for every cylinder of the internal combustion engine, with a high-pressure fuel pump (10) and with a fuel injection valve (12) linked therewith. A pump piston (18) of the high-pressure fuel pump (10) delimits a pump working compartment (22) that is linked with a pressure compartment (40) of the fuel injection valve (12). Said fuel injection valve has an injection valve member (28) that controls injection openings (32) and that is displaced in an opening direction (29) against a closing force by the pressure prevailing in the pressure compartment (40). A control valve (80) controls the link (74) of a control pressure compartment (62), linked with the pump working compartment (22) and limited by a control piston (60), with a discharge compartment (24) in which a throttle element (75) is provided. The control piston (60) controls an effective area of flow of the link (74) of the control pressure compartment (62) to the discharge compartment (24) in accordance with the stroke of the control piston (60) in such a manner that, as the opening stroke of the injection valve member (28) increases, the control piston (60) releases a smaller effective area of flow. At a maximum opening stroke of the injection valve member (28), the released effective area of flow is smaller than the effective area of flow of the second throttle element (75).
