摘要： An electric motor includes a cylindrical stator that is formed with a plurality of slots. The cylindrical stator has polyphase coils that are formed by winding a plurality of conductive wires in the slots to have polyphase, a wire bundle and an insulating tube covering the wire bundle. Each conductive wire includes a core wire and an insulator that covering the core wire. The wire bundle has a drawing portion, a connecting portion and an elongated portion that is elongated between the drawing portion and the connecting portion for increasing creepage distance between the connecting portion and the housing thereby to increase insulation resistance. The connecting portion of the wire bundle provides a neutral point of the electric motor. The elongated portion and the connecting portion of the wire bundle are covered with the insulating tube.

摘要： A compressor housing defines a motor accommodating chamber. The pressure in the motor accommodating chamber is equal to the pressure in a suction chamber. A first reservoir chamber is located in a discharge chamber. A second reservoir chamber is defined about the discharge chamber. A communicating passage connects the first reservoir chamber with the second reservoir chamber. A restrictor is located in the communicating passage. An oil return passage connects the second reservoir chamber with the suction chamber. A connecting passage connects the motor accommodating chamber with the suction chamber. Therefore, leakage of electricity is prevented.

摘要： A control valve used for a variable displacement type compressor. The compressor has a crank chamber, a discharge pressure zone, and a supply passage. The supply passage connects the crank chamber to the discharge pressure zone. The control valve is located in the supply passage. The control valve has a valve body. The valve body adjusts the size of the opening of the supply passage in accordance with the discharge pressure. The valve body is exposed to the pressure of the supply passage. The valve body moves in accordance with the discharge pressure such that the displacement is varied to counter changes of the discharge pressure. The direction in which the valve body moves in response to an increase of the discharge is the same as the direction in which the valve body moves when the pressure of the supply passage increases.

摘要： A piston type compressor has a housing, a crank chamber and a drive shaft supported by the housing. A front restriction and a rear restriction are located in the housing. The front and rear restrictions restrict axial movement of the drive shaft. The front restriction restricts forward movement of the drive shaft. The rear restriction restricts rearward axial movement of the drive shaft. A first clearance is located between the rear end of the drive shaft and the rear restriction when the drive shaft is restricted by the front restriction. A second clearance is formed between the piston and a valve plate when the drive shaft is restricted by the front restriction and when the piston is in the top dead center position. The first clearance is narrower than the second clearance. The method of assembly the piston easily sets the first clearance.

摘要： A displacement control device comprises a control valve. The control valve controls the pressure in a crank chamber. The control valve includes a valve body, and an electromagnetic actuator. A power source supplies the current to the actuator. A switch device located between the actuator and the power source. A controller determines a target value of the current supplied to the actuator in accordance with an external condition. When the target value is changed to a new value, the controller controls the switching of the switch device such that the current is intermittently supplied from the power source to the actuator before the current is set to the new target value. This permits the displacement of the compressor to be smoothly and rapidly changed.

摘要： A variable displacement compressor is operated efficiently by avoiding inefficient conditions. The compressor varies its displacement using a control valve for which an external duty control procedure is performed. A target value for controlling the displacement is determined in accordance with the duty ratio Dt of a drive signal sent to the control valve. If the duty ratio Dt is equal to or greater than a predetermined reference value DJ, the displacement is permitted to be varied corresponding to the duty ratio Dt. If the duty ratio Dt is smaller than the reference value DJ, the variable displacement control through the duty control procedure is suspended. In this case, the compressor is operated with a nullified duty ratio (Dt=0), or a minimum displacement.

摘要： A control valve used in a variable displacement compressor includes a valve chamber, a valve body and a pressure sensing chamber. A pressure sensing ball is movably located in the pressure sensing chamber and divides the pressure sensing chamber into a first pressure chamber and a second pressure chamber. First and second pressure monitoring points are located in a refrigerant circuit. The first pressure chamber is exposed to the pressure at the first pressure monitoring point. The second pressure chamber is exposed to the pressure at the second pressure monitoring point. The ball is displaced based on the pressure difference between the first pressure chamber and the second pressure chamber. The position of the valve body is determined based on the position of the pressure sensing member.
