Abstract

A high pressure pump (1) used in particular as a radial or in line piston pump for fuel injection systems of air compressing self igniting internal combustion engines comprises a pump housing (2) and a cylinder head (3) connected to said pump housing (2). A pump assembly (6) and a drive shaft (7) mounted in the pump housing (2) are also provided. The drive shaft (7) is used to drive the pump assembly (6). The pump assembly (6) has a tappet body (10) and a tappet spring (40). The tappet body (10) is guided at least in sections on a projection (5) of the cylinder head (3). The tappet spring (40) encloses the tappet body (10) at least in sections. In this way the tappet spring (40) can be designed with a large diameter.
