摘要： A variable displacement type compressor circulates a refrigerant in an air conditioning circuit. The compressor has a compression mechanism and a displacement controller. The compression mechanism compresses and discharges the refrigerant. The displacement controller controls the discharge amount of the refrigerant of the compressor. The displacement controller further includes a normal control means and a protective control means. The normal control means controls the displacement based on a cooling load. The protective control means controls the displacement based on the value in connection with the rotational speed of the compressor and the actual operating information of the compressor.

摘要： A compressor torque estimate device is used for a variable displacement compressor whose displacement is variable based on a compressor control signal for estimating a compressor torque of the compressor. The compressor torque estimate device includes a torque calculator and a corrector. The torque calculator calculates a torque required for driving the compressor based on the compressor control signal, thereby obtaining a calculated torque. The corrector corrects the calculated torque by a procedure of first-order lag, thereby obtaining a corrected torque. The corrector also estimates the corrected torque to be the compressor torque.

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 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 heat-insulating mechanism in a compressor which introduces refrigerant gas from a suction pressure region to a compression chamber and discharges the refrigerant gas from the compression chamber to a discharge pressure region has a circular passage, a communication passage, a cylindrical member and a passage heat-insulating member. The circular passage, which is a portion of the suction pressure region, has a circular cross-section, and is in communication with an external refrigerant circuit. The communication passage, which is a portion of the suction pressure region, intersects the circular passage for connection therewith, and is communicable with the compression chamber. The cylindrical member is fitted into the circular passage. The passage heat-insulating member made of an insulating material covers at least a portion of a passage wall surface which forms the communication passage. Rotation of the cylindrical member is prevented by engaging the passage heat-insulating member with the cylindrical member.

摘要： A control valve is located in a variable displacement compressor that is installed in a refrigerant circuit. The control valve operates such that the pressure difference between first and second pressure monitoring points in the refrigerant circuit seeks a predetermined target value. The first pressure monitoring point is located in a discharge chamber of the compressor. The second pressure monitoring point is located in a flow pipe that extends from the discharge chamber. The static pressure of refrigerant in the discharge chamber is introduced into a control valve from the first pressure monitoring point. A pressure that includes the static pressure and the dynamic pressure of refrigerant in the flow pipe is introduced into the control valve from the second pressure monitoring point. As a result, the displacement of the compressor is reliably controlled without being affected by the thermal load of an evaporator.
