Abstract

The invention relates to a pump having a valve through which a fluid can optionally flow. The valve is embodied by a cavity for displaceably guiding a spherical blocking body, and a valve seat that is spatially adapted to the spherical shape of the blocking body. A free space protruding radially outwards from the spherical body is located downstream, directly behind the valve seat, for temporarily receiving the fluid which flows through the valve seat.
