Abstract: A variable displacement compressor includes a plate having a variable inclination angle, and a piston engaging the plate. The piston reciprocates within a bore of the compressor in accordance with a rotation of the plate, and the piston has a stroke length which is determined by the inclination angle of the plate. The compressor also includes a sensor positioned adjacent to the piston. The sensor generates an output signal when a predetermined portion of the piston is aligned with the sensor. The compressor also includes a processing unit operationally coupled to the sensor. The processing unit estimates the inclination angle of the plate based on the output signal from the sensor.

Abstract: A compressor includes a front housing, a cylinder block, a cylinder head, and a torque transmission mechanism. The torque transmission mechanism includes a pulley, a plate-shaped elastic member connected to the pulley, a hub connected to the plate-shaped elastic member, a drive shaft connected to the hub, and a rotor connected to the drive shaft. The compressor also includes a reciprocating mechanism connected to the torque transmission mechanism. The compressor further includes torque determination means. The torque determination means includes a first marker affixed to the pulley and a second marker affixed to the hub. The torque determination means also includes a first sensor affixed to the front housing which generates a first timing signal when the first marker is positioned within substantially the same vertical plane as the first sensor. The torque determination means further includes a second sensor affixed to the front housing which generates a second timing signal when the second marker is positioned within substantially the same vertical plane as the second sensor. Further, there is a time differential between when the first marker is positioned within substantially the same vertical plane as the first sensor and when the second marker is positioned within substantially the same vertical plane as the second sensor. Moreover, the time differential corresponds to the angular offset and the torque of the compressor is determinable from the time differential.

Abstract: A hydraulic pump control system is shown that can control the absorbing torque of a hydraulic pump with respect to the engine power for driving the hydraulic pump in a well-balanced manner, and reduce a deviation of an actual revolution number from a target revolution number of the engine. A torque of hydraulic pumps during operation is estimated from a pump pressure and first and second line pressures. Based on the estimated torque, an output torque of the hydraulic pumps is controlled so that an error between a target revolution number and an actual revolution number of the engine becomes null.

Abstract: There is provided a displacement control system for a variable displacement hydraulic pump which has a displacement control piston assembly (6) having a large diameter chamber (7) for operating a displacement control member (5) of the variable displacement hydraulic pump selectively in a direction of smaller displacement and in a direction of larger displacement, first control valve (8) and second control valve (9) for selectively communicating the large diameter chamber of the displacement control piston assembly with a pump discharge line and a tank, the first control valve being placed at a supply position by the pump discharge pressure, and at a drain position by a spring associated with the displacement control piston assembly via a feedback lever, and the second control valve being placed at a first position by the pump discharge pressure for communicating the pump port and the large diameter chamber and at a second position by a load pressure for communicating the pump port and the large diameter chamber and at a second position by a load pressure for communicating the large diameter chamber to the first control valve, the flow path area is varied at the intermediate position of a fluid passage from the large diameter chamber to the pump discharge passage or to a tank. With the construction set forth above, supply speed and drain speed of the pump discharge pressure to and from the large diameter chamber of the displacement control piston assembly is varied by variation of cross-sectional flow area at the intermediate position of the fluid passage. By this, response characteristics in displacement control of the variable displacement hydraulic valve can be adjusted to improve operability of a work implement.

Abstract: A pump displacement control for a variable displacement pump includes a torque control valve serially disposed between a remotely controllable displacement control valve and a variable torque limiter in axial alignment within a common bore. A displacement control sleeve is disposed within the bore for normally controlling the fluid pressure in an actuating chamber of an actuator connected to a swashplate of the pump when the pump discharge pressure is below a predetermined high pressure. The torque control valve assumes control of pump displacement when the pump discharge pressure exceeds the predetermined high pressure and includes a sleeve and a valve spool movable relative to each other to establish a first condition communicating discharge pressure into the actuator chamber to move the swashplate toward a minimum displacement position or a second condition communicating the actuating chamber with an exhaust passage so that the swashplate is moved toward its maximum displacement position. A feedback piston continuously subjected to pump discharge pressure moves the valve spool in a direction to establish the first condition when discharge pressure exceeds the predetermined high pressure. The feedback piston is disposed in axial alignment with the valve spool within an insert disposed within the displacement control sleeve. The predetermined high pressure is varied by increasing or decreasing the level of a control pressure directed into a bore receiving a piston acting on the opposite end of the valve spool.
