The output regulator for a radial piston pump (10) according to Fig.1 has a valve (23), which controls a pressure chamber (38) on a control piston (12) determining the adjustment of the lifting ring. In addition the device has two measuring pistons (28, 31) subjected to pressure, which act on the valve (23) by way of a lever (46). Two compression springs (40, 41), by means of which a roughly approximated output hyperbola is achieved, act in succession on the valve counter to this force. A pressure cut-off is achieved by means of a pressure limiting valve (34) post-connected to the measuring piston (28, 31), and limiting of the delivery quantity is achieved by means of a variable throttle (17). <IMAGE>
