Abstract: A variable displacement main pump (11) driven by an engine (13) is provided with a capacity control means (35) for variably controlling a discharge flow rate. According to an engine revolution speed detected by an engine revolution speed detector (44) and a pump discharge pressure from the main pump (11) detected by a pump discharge pressure detector (42), a power shift pressure output from a solenoid proportional reducing valve (46) is controlled by a signal output from a controller (45). The power shift pressure is led to a regulator control valve (39) of the capacity control means (35), and a tilt angle of the swash plate (36) of the main pump (11) is controlled by a regulator (37) to thereby shift-control pump discharge pressure - discharge flow rate characteristics to optimal levels. Whereby, a pump control device is provided that can reduce changes in engine revolution speed when a load pressure is rapidly changed.

Abstract: A flow control system for controlling a variable displacement pump including a metering valve in fluid communication with the pump for metering an output of the pump. A regulating valve receives a portion of the output of the pump as a bypass flow at a first pressure, wherein an output of the regulating valve is at an interim pressure. The interim pressure is substantially equal to an average of the first pressure and a low reference pressure. An actuator sets a displacement of the pump by acting on a piston connected to a cam ring of the pump. The actuator receives the interim pressure and, thereby, the output of the variable displacement pump is determined.

Abstract: Variable delivery main pumps (11) driven by an engine (13) have a capacity control means (35) for changing the discharge rates of the pumps. Power shift pressure output from a proportional control solenoid valve (46) based on signals from a controller (45) is controlled in accordance with the engine speed detected by an engine speed detector (44) and pump delivery pressure of a main pump (11) detected by a pump discharge pressure detector (42). The power shift pressure is introduced into a regulator control valve (39) of the capacity control means (35), and an angle of a swash plate (36) of the main pump (11) is controlled by a regulator (37) so that the pump discharge pressure - discharge rate characteristic is shifted to be optimized. With the configuration as above, the invention provides a pump control device that is capable of reducing the degree of change in the engine speed occurring due to a sudden change in load pressure.

Abstract: The invention concerns an output and moment regulation device for an adjustable hydraulic pump (1) with a hydraulic servo setter for the continuous adjustment of the delivery rate. Adjustment of the delivery rate is dependent on the delivery pressure of the hydraulic pump (1) in a delivery pressure line (10) and an actuating pressure in a control line (12), and the setter is provided with a spring (4) which forces a pump regulating member (3) in the direction of maximum delivery rate and with at least one piston (6) which acts on the pump regulating member (3) in the direction of delivery rate 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) is actuated by actuating pressure in the control line (12), and a moment valve (17) is provided whose closure force is set by a metering spring arrangement (18) connected to the pump regulating member (3) and pre-stressed in accordance with the delivery pressure 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 branches off 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) and moment valve (17), specifically, on the closure members thereof.

Abstract: A pump displacement control (10) for a variable displacement pump (11) includes a torque control valve (26) disposed between a variable torque limiter (34) and a force applying device (60) disposed in axial alignment within a common bore (19). A sleeve (27) and a valve spool (29) are movable relative to each other to establish a first condition communicating discharge pressure into an actuator chamber (17) to move a swashplate (12) toward a minimum displacement position against the bias of a spring (16) or a second condition communicating the actuating chamber with an exhaust passage (23) to allow the spring to move the swashplate toward its maximum displacement position. A torque control piston (39) disposed between opposing springs (48,49) resiliently bias the valve spool in a direction to establish the second condition when control fluid is directed into a control chamber (46). Pump discharge pressure communicated into a pressure chamber (63) exerts a force against the valve spool proportional to the discharge pressure so that the valve spool moves in a second direction to establish the first condition when the control force exceeds the biasing force exerted by the torque limiter.
