Abstract
The present disclosure relates to high-pressure fuel pumps and the teaching may be applied to pumps in which a pump piston, by means of which a fuel is acted on with a high pressure, is guided in a guiding sleeve. In some embodiments, a high-pressure fuel pump may include: a housing having a housing recess; a pump piston for pressurizing a fuel; and a guiding sleeve arranged in the housing recess and guiding the pump piston. The guiding sleeve is connected to the housing recess with a materially engaging connection.
