A high-pressure pump (1), which serves in particular as a radial or inline 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). |
