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： An air-conditioning system has a refrigerant circuit. The circuit includes a condenser, a expansion valve, an evaporator and a variable displacement compressor. The system has a pressure difference detector. The pressure difference detector detects the pressure difference between two pressure monitoring points located on the refrigerant circuit. A control valve and a controller control the displacement of the compressor in accordance with the pressure difference detected by the pressure difference detector. This permits the displacement of the compressor to be quickly changed.

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.

摘要： A compressor has a cam plate located in a crank chamber and mounted on a drive shaft and a piston coupled to the cam plate and located in a cylinder bore. The piston compresses gas supplied to the cylinder bore from a separate external circuit by way of a suction chamber and discharges the compressed gas to the external circuit by way of a discharge chamber. The cam plate is tiltable between a maximum inclined angle position and a minimum inclined angle position with respect to a plane perpendicular to an axis of the drive shaft according to a difference between the pressure in the crank chamber and the pressure in the cylinder bore. The piston moves by the stroke based on an inclination of the cam plate to control the displacement of the compressor. A valve is placed between the discharge chamber and the external circuit. The valve selectively connects and disconnects the discharge chamber with the external circuit based on a difference between the pressure acting on the upstream side of the valve and the pressure acting on the downstream side of the valve.

摘要： A control valve for a variable displacement compressor. The control valve has a valve body for regulating gas flow. A bellows actuates the valve body through a first rod in accordance with an operating pressure introduced to a pressure sensing chamber. A solenoid biases the valve body through a second rod with a force based on the level or an electric current supplied to the solenoid. The cross-sectional area of the second rod is no smaller than the cross-sectional area of a valve hole of the control valve.

摘要： A sealing structure for the shaft of a compressor. The sealing apparatus includes an inner ring, and outer ring, and a support ring. The inner ring and the outer rings have flexible annular lips that contact the surface of the rotary shaft. The support ring supports the inner lip and determines the position of the inner lip. The first lip permits fluid leakage along the surface of the shaft, while the second lip forms a fluid-tight seal with the shaft. The support ring prevents the internal pressure of the compressor from pressing the first lip against the shaft with excessive force, which extends the life of the sealing apparatus.

摘要： A compressor housing and method of manufacture and assembly are disclosed. The compressor housing includes a cylinder block and a front housing. An annular projection is formed on the front end of the cylinder block. An annular groove is formed on the rear end of the front housing. The cylinder block and the front housing are secured to each other to prevent the front housing from being displaced in relation to the cylinder block by engaging the annular projection with the annular groove. A gasket is located between the front end of the cylinder block and the rear end of the front housing secured to each other to seal between the cylinder block and the front housing. This compressor and its method of manufacture reduce the amount of misalignment between a shaft bore in the cylinder block and a shaft bore in the front housing, which improves the performance of the compressor.
