Title: HIGH-PRESSURE FUEL PUMP
Abstract:
The invention relates to a high-pressure fuel pump (22) comprising a piston (34) and a piston chamber (26), which can be connected to a low-pressure region (28) via an inlet valve (24), wherein the inlet valve (24) comprises a valve seat (86) having a sealing face (98) and a valve body (82), and wherein, when the inlet valve (24) is closed, the sealing face (98) of the valve seat (86) rests in a sealing manner on the valve body (82) and, radially inward of the valve seat (86), an opening area (102) that is subjected to the medium (104) in the low-pressure region (28) is formed on the valve body (82), and wherein the sealing area (98) has an area center of gravity (106) that is different from an area center of gravity (108) of the opening area (102).
