摘要：The invention concerns an output and moment regulation device for an
adjustable hydraulic pump (1) with a hydraulic servo setter for the continuous adjustmentof the delivery rate. Adjustment of the delivery rate is dependent on the deliverypressure of the hydraulic pump (1) in a delivery pressure line (10) and an actuatingpressure in a control line (12), and the setter is provided with a spring (4) which forces apump regulating member (3) in the direction of maximum delivery rate and with at leastone piston (6) which acts on the pump regulating member (3) in the direction of deliveryrate reduction. The piston face can be subjected via a hydraulically operated control valve(8) to the feed pressure, or is connected to a discharge (19), the control valve (8) isactuated by actuating pressure in the control line (12), and a moment valve (17) isprovided whose closure force is set by a metering spring arrangement (18) connected tothe pump regulating member (3) and pre-stressed in accordance with the deliverypressure setting; and the moment valve (17) connects the control line (12) to the
discharge (19) in accordance with the control pressure in the control line (12) and the pre-stress in the metering spring arrangement (18); and the control line (12) which branchesoff from the operating pressure line (15) of the pump is provided with an adjustable
choke device (13) for adjusting the control pressure acting on the control valve (8) andmoment valve (17), specifically, on the closure members thereof.
