    摘要: A fluid machine is served as an expansion device and a compression device. The fluid machine compresses gas in an operation chamber upon functioning as the compression device. The fluid machine expands the gas in the operation chamber upon functioning as the expansion device. The fluid machine includes a movable discharge valve served as a differential pressure regulating valve that discharges the gas from the operation chamber when the fluid machine functions as the compression device. The discharge valve is moved to a non-operation position where the discharge valve fails to function as the differential pressure regulating valve when the fluid machine functions as the expansion device.

    摘要: Variable displacement compressors (101) include a displacement control valve (181) that is in communication with a drive chamber (111). The output displacement of the compressor varies in response to changes in pressure within the drive chamber. A controller (203) may control the displacement control valve so that the pressure within the drive chamber is maintained within a predetermined range. Further, the predetermined range may be determined based upon one or more factors that cause fluctuations in the pressure within the drive chamber during operation of the compressor.

    摘要: A control valve has a valve housing. A valve chamber and a pressure sensing chamber are defined in the valve housing, respectively. A pressure sensing member is located in the pressure sensing chamber. A pressure sensing rod is slidably supported by the valve housing. A valve body is accommodated in the valve chamber. An end of the pressure sensing rod is connected to the pressure sensing member and the other end of the pressure sensing rod contacts the valve body. A solenoid chamber is defined in the valve housing. A stationary iron core is located between the valve chamber and the solenoid chamber. A solenoid rod extends through and is slidably supported by the stationary iron core. An urging force applied to the pressure sensing member by an actuator through the solenoid rod corresponds to a target value of the pressure difference. The pressure sensing member moves the valve body such that the pressure difference seeks the target value.

    摘要: A vehicle air conditioner including a refrigerant circuit that incorporates a variable displacement compressor driven by an engine of the vehicle. The air conditioner includes a control valve for varying the displacement of the compressor and an ECU for controlling the control valve. The control valve has a bellows, a valve body, and a coil. The ECU varies the displacement of the compressor by energizing the coil to apply a force, which counters the movement of the bellows, to the valve body to move the valve body. This alters the moved amount of the bellows. The air conditioner control unit gradually changes the force applied to the valve body by the coil to adjust the pressure difference and vary the displacement of the compressor when the engine is running at an idle speed.

    摘要: A compressor has a swash plate supported on a drive shaft for an integral rotation. The swash plate is coupled to a plurality of pistons reciprocally moveable in a cylinder block to compress gas therein. Reaction force of the compressed gas applied to the piston and causing axial load acting on the swash plate and the drive shaft is buffered by buffer structure. The buffer structure comprises a first bearing interposed between a first surface of the swash plate and the cylinder block. The buffer structure has a second bearing interposed between a second surface of the swash plate and the cylinder block. One of the bearings is arranged to be flexibly deformable to absorb the axial load while the other bearing is arranged to be rigid to receive the axial load and transmit the axial load to the cylinder block.

    摘要: A displacing device is incorporated in a displacement control valve. The displacing device includes a first pressure chamber, a second pressure chamber, a second bellows, a transmission rod, and an urging spring. The second pressure chamber communicates with a suction chamber. The interior of the second pressure chamber is a suction pressure zone. When the pressure in the suction pressure zone is less than or equal to a predetermined reference pressure, the transmission rod moves an actuation rod (valve body) to open a valve hole. Therefore, a variable displacement compressor is prevented from operating with a large displacement when there is insufficient amount of refrigerant or when the speed of the compressor is high.

    摘要: A controller for a variable displacement compressor that maintains high displacement while preventing excessive increase in discharge pressure. The controller includes a pressure sensing mechanism for detecting pressure of a suction pressure region in the compressor. A suction pressure controlling means controls the displacement of the compressor so that the pressure detected by the pressure sensing mechanism is converged to a predetermined suction pressure setting. A sensor detects pressure of a discharge pressure region in the compressor. A discharge pressure controlling means controls the displacement of the compressor so that the pressure detected by the sensor is converged to a predetermined discharge pressure setting. When the pressure detected by the sensor is greater than a threshold pressure, an ECU switches the control of the compressor from control with the suction pressure controlling means to control with the discharge pressure controlling means.

    摘要: A displacement control valve for a variable displacement compressor includes a valve hole partially forming a supply passage or a bleed passage of the compressor and a valve body having a cross-sectional area changed portion that is movable into and out of the valve hole. The cross-sectional area changed portion has a minimum cross-sectional area portion and a maximum cross-sectional area portion. The cross-sectional area changed portion is shaped so that the cross-sectional area of the cross-sectional area changed portion increases from the minimum cross-sectional area portion to the maximum cross-sectional area portion. The minimum cross-sectional area portion initially enters into the valve hole when the cross-sectional area changed portion is moved into the valve hole. The maximum cross-sectional area portion is movable into the valve hole. The valve hole is closed when the maximum cross-sectional area portion is positioned in the valve hole.
