The radial piston pump has several cylinder bores in the pump body for the delivery pistons. The bores are closed by valve stoppers (5) which have pressure channels passing through same each taking an outlet valve which has a ram (7) which is provided with an impact plate (8) on the end facing the delivery piston (1).
