PCT No. PCT/EP96/04335 Sec. 371 Date Apr. 13, 1998 Sec. 102(e) Date Apr. 13, 1998 PCT Filed Oct. 8, 1996 PCT Pub. No. WO97/14889 PCT Pub. Date Apr. 24, 1997The invention relates to a device for the output regulation of at least one variable displacement pump (1), delivering into a working line, driven by a motor, through adjustment of its displacement by means of a setting device (7) biased in the direction of maximum displacement and which can be acted upon with a setting pressure (20), having a regulation valve (18) associated with the setting device (7), which regulation valve can be acted upon by a counter-pressure corresponding to the working pressure in the working line, whereby the regulation valve (18) responds when the control pressure is greater than the counter-pressure, and so regulates the setting pressure action on the setting device (7) in the direction of a reduction of the displacement of the variable displacement pump (1) that the product of working pressure and output is constant. Thereby a device (25) is provided through which the setting of the setting device (7) can be detected and which delivers to an electronic control unit (40) a setting signal proportional to the setting. Further, a pressure limiting valve (42) is provided by means of which the maximum counter-pressure in the regulation valve (18) can be set. The electronic control unit (40) controls the pressure limiting valve (42) in dependence upon the detected setting signal from the setting detector (25). The invention further relates to a method of regulating the output of a variable displacement pump (1), delivering into a working line, driven by a motor (6).
