Abstract (en)
[origin: DE19748750A1] The inventive radial piston pump has a number of cylinder bores in a pump housing to accommodate the pistons which slide into them. Said cylinder bores are plugged by pressed-in stoppers (3). Pressure channels are incorporated into the stoppers and all of the stoppers are sealed by a flat spiral spring (6) which serves as a return valve. Each stopper (3) has at least one side discharge channel (8, 9) in order to increase the outflow cross section through the pressure channels.
