Abstract

The invention relates to a pump, in particular a high-pressure fuel pump of an internal combustion engine, having a pump cylinder (2), which is covered by a pump cylinder head (1) and in which a pump plunger (3) can be moved up and down in a translatory manner, wherein the pump plunger (3) together with the pump cylinder head (1) delimits a pump working chamber (4), which is connected via an inlet valve (5) to a low-pressure connection and via an outlet valve (6) to a high-pressure connection, and wherein the inlet valve (5) and the outlet valve (6) are arranged axially in relation to each other. According to the invention, a pump with an inlet valve (5) and an outlet valve (6) having good closing behaviour is provided. This is achieved in that the inlet valve (5) and the outlet valve (6) have a guided valve body (15, 15a).
