In a radial piston pump (,), which has pump elements (,) arranged radial in the pump housing (,) and which in turn have an inlet valve (,) and an outlet valve (,) activated by the medium, the valves (,) are disposed at the outer side of the pump elements (,) whereby the inlet valves (,) are arranged coaxial relative to the pump piston (,). All inlet valves (,) are connected to a joint intake channel (,) that leads around the outside of the pump housing (,). To achieve a simple, flexible and operationally dependable design with a high degree of efficiency and low noise emission, the pump elements (,) are inserted from the outside and held in place in a bore (,) of the pump housing (,) as a complete unit, consisting of a cylinder barrel (,), a pump piston (,) and an inlet valve (,), and the joint inlet channel (,) is designed as a groove (,) that is open to the outside, which is covered with a fitted sealing member (,) after mounting of the pump element (,) onto the pump housing (,), and whereby said channel (,) is connected with the tank (,) via at least one bore (,) in the pump housing (,).
