Fuel pump, in particular high pressure - fuel pump for a fuel system of an internal combustion engine with gasoline direct injection -

摘要

A fuel pump (10) comprises a piston (18) as well as drive means (24) for driving the piston (18). The piston (18) is in a cylinder (12), and a cylinder head (14) is connected to the cylinder (12) with a generally annular contact surface (44) to. At least one attachment means (58) acts on the cylinder head (14) with the annular contact surface (44) against the cylinder (12). In order to reduce the production costs, it is proposed that the annular contact surface (44), and the working region (64) of the fastening means (58) on the cylinder head (14) in the longitudinal direction (66) of the cylinder (12), substantially at the same level.
