摘要： A variable capacity type compressor includes a swash plate and pistons to effect compressing action. The tilting position of the swash plate is controlled by the pressure in a control pressure chamber into which a coolant in the discharge pressure region is introduced. The pressure in the control pressure chamber is controlled by a capacity control valve mounted to the rear housing in an inclined position relative to a plane perpendicular to the axis of the rotatable drive shaft.

摘要： In a fitting structure of a control valve in a variable capacity compressor according to the present invention, a step portion 92 is formed by connecting two taper surfaces 93a and 93b, the diameter of each of which decreases progressively towards the depth of a fitting hole 32 (in an inserting direction of a control valve 33) between each step surface portion 57, 67, 74, 91 of a fitting hole 32. A first taper surface 93a at a deep part of each step portion 92 has a smaller inclination in the inserting direction than a second taper surface 93b on the inlet side. The first taper surface 93a is formed so that its inner diameter on the inlet side is a little greater than the outer diameter of each O-ring 61, 70, 77 disposed on each step surface portion 57, 67, 74 in a free condition.

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 apparatus that promptly increases the displacement of a compressor after the compressor is started while liquefied refrigerant is lingering in an external circuit. The control apparatus includes a restricting passage. The restricting passage is located in a first pressure introduction passage, through which the pressure of the first pressure monitoring point flows to the control valve. The restricting passage decreases the pressure of refrigerant that flows through the passage. When the compressor is started while liquefied refrigerant is lingering in the external circuit and the pressure of the first pressure monitoring point is abruptly increased, the restricting passage reduces the increase of the pressure that is detected by the control valve. Therefore, the displacement of the compressor is promptly increased.

摘要： An electric compressor includes a motor and a compression mechanism that is driven by the motor. The compressor forms part of the refrigerant circuit of an air conditioner. A control apparatus of the compressor adjusts the rotation speed of the motor for controlling the amount of compressed refrigerant gas discharged from the compression mechanism, or the displacement of the compressor, per unit time. When the energy efficiency of the motor is lower than a predetermined level, the control apparatus performs on-off control by alternately turning off the motor. During the on-off control, a required amount of refrigerant gas discharged per unit time is obtained, and the energy efficiency of the motor in the on time is higher than the predetermined level.

摘要： A variable displacement compressor air conditions a compartment and includes a suction chamber, a discharge chamber and a crank chamber. A controller controls the pressure in the crank chamber to vary the compressor displacement. Two pressure monitoring points are located in a refrigerant circuit. The pressure in the crank chamber is controlled by a control valve. The control valve operates based on the pressure difference between the monitoring points such that a target pressure difference is maintained. A temperature sensor monitors the temperature of the compartment. A detection circuit compares the monitored temperature with reference values. When the monitored temperature surpasses one reference value or falls below another, the detection circuit outputs a detection signal. When receiving the detection signal, a pressure difference changer gradually increases or decreases the target value of the pressure differences accordingly.
