PCT No. PCT/CH88/00014 Sec. 371 Date Sep. 27, 1988 Sec. 102(e) Date Sep. 27, 1988 PCT Filed Jan. 25, 1988 PCT Pub. No. WO88/05863 PCT Pub. Date Aug. 11, 1988.A fuel injection pump has a housing (3) with a flange (5) and a bore (40) in which are arranged a sleeve (2) and a pump piston (1). A valve body (4) with a hollow core space (20) is located in an axial end portion of the sleeve (2). The valve body (4) has at both axial end portions (11, 12) hydraulic dampening means. In the zone of the top dead center of the pump piston (1), its head (13) cooperates directly with the axial end portion (11) of the valve body (4), actuating a valve seat (27). This valve seat (27) located between the valve body (4) and the sleeve (2) acts as a fuel intake and relief valve for the fuel delivery system. A fluid spring including a cylinder chamber (42) and an additional piston (44), as well as an actuating element (19), are located adjacent an axial end of the pump piston (1 ). The actuating element (19) is linked with a drive.
