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： A control valve is used for a variable displacement compressor installed in a refrigerant circuit of an air conditioner. The compressor has a control chamber and a control passage, which connects the control chamber to a pressure zone in which the pressure is different from the pressure of the control chamber. The control valve has a valve body, which is accommodated in the valve chamber for adjusting the opening size of the control passage. A pressure sensing member moves in accordance with the pressure difference between two pressure monitoring points located in the refrigerant circuit. The pressure sensing member moves the valve body such that the displacement of the compressor is varied to counter changes of the pressure difference. The force applied by an actuator 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. An urging member is accommodated in the valve chamber. The urging member urges the valve body in a direction to open the control passage.

摘要： A displacement control valve for a variable displacement compressor. The displacement control valve includes a drive force transmission body, a pressure sensitive chamber, an internal passage, and a valve body. The valve body includes an annular seal which is contactable with a valve seat surface facing toward the first valve body. The drive force transmission body includes a drive rod and a valve body structure having a shaft passage and forming the first valve body. The drive rod is fitted to the shaft passage and coupled to the valve body structure so as to form a gap passage between an outer surface of the drive rod and a wall surface of the shaft passage. The internal passage includes a recess arranged radially inward from the annular seal, the shaft passage, and the gap passage. The gap passage is in direct communication with the recess.

摘要： A displacement control valve for a variable displacement compressor includes a first valve hole forming a part of a supply passage and a second valve hole forming a part of a discharge passage. Displacement of a reciprocating body is transmitted to each of first and second valve bodies so that each valve body opens or closes the corresponding valve hole. When the reciprocating body is within a predetermined displacement range, a double closing state occurs, in which the first valve body closes the first valve hole and the second valve hole closes the second valve hole. When the reciprocating body is out of the displacement range, a single closing state occurs. Therefore, the control valve prevents the first valve hole from opening concurrently with the second valve hole.

摘要： In a control system of a variable displacement compressor, a pressure sensing means mechanically detects at least one pressure in the refrigerant circuit. A varying means varies a reference value for positioning a valve body. A pressure detector electrically detects the pressure detected by the pressure sensing means in the refrigerant circuit and/or physical quantity which correlates with the detected pressure. A calculator calculates a maximum value of urging force applied to the valve body by the varying means toward an increasing side of the displacement of the compressor. The urging force applied to the valve body is controlled not to exceed the maximum value toward the increasing side of the displacement. The displacement of the compressor is maximized by the pressure sensing means under the pressure for calculating the maximum value when the varying means applies urging force of the maximum value to the valve body.
