Abstract
The radial piston pump has a number of cylinder bores in a pump housing to accommodate pistons which slide into them; the cylinder bores are plugged by pressed-in stoppers (3) in which pressure channels are incorporated, all stoppers being sealed by a flat spring (6) which serves as return valve. To enlarge the outflow cross section through the pressure channels, each stopper 3 has at least one side discharge channel (8, 9).
