  • Patent number: 6477940
    Abstract: The invention relates to a high-pressure piston cylinder unit, especially an injection pump or an injection valve for an internal combustion engine, and to a method for producing one such high-pressure piston cylinder unit. The high-pressure piston cylinder unit has a piston which is guided inside a cylinder bore and which is coupled to an actuating element. The piston is subjected to a high pressure differential. According to the invention, fine grooves which run very close to one another are configured in at least one part of the guiding surface of the piston. The grooves ensure hydraulic pressure compensation on the periphery of the guiding surface, thus reducing wear, and prevent leakage in a longitudinal guiding direction.
