Abstract (en)

[origin: EP1304482A2] The cumulative power control for a number of hydrostatic piston machines (5,5',5), e.g. hydropumps, includes a pressure system to generate a common control parameter. The pumped volume is adjusted by setting units (8,8',8,9,9',9), for the pumps to force a pressure medium into their outflow channels (6,6',6). The setting units are controlled by a regulator (7,7',7), with a deflection lever with a torque applied to it proportional to the pumped volumes and the pressures in the pump outflow channels, to act on the regulating pistons. The operating pressures of the pumps are passed to the pressure monitor (12). The separate regulators for each pump each have a regulating piston and a measurement piston which is under an axial force which is transferred to the regulating piston. A counter force is applied to a measurement piston surface by the pressure monitor.
