Plunger for a high-pressure pump and high-pressure pump, with at least one plunger

摘要

It is a plunger for a high-pressure pump, in particular for fuel delivery, is proposed. The plunger (52) is used for the at least direct support of a pump piston (34) to a drive mechanism (12). The plunger (52) has a sleeve-shaped design and constructed as a sheet metal part. The high-pressure pump has a housing (10), in which a rotationally drivable drive shaft (12) and at least one pump element (32) is arranged, the one hand, by the drive shaft (12) at least indirectly driven in a reciprocating motion, pump piston (34), wherein the pump piston (34) in the housing by a (10), which is displaceably guided plunger (52) at least indirectly on the drive shaft (12) is supported. The plunger (52) has a sleeve-shaped design and constructed as a sheet metal part.
