摘要： The present invention provides a piston type compressor in which vibration and noise due to interference between the piston and the cam plate can be suppressed by preventing the rotation of the piston, and at the same time, it is possible to improve the productivity and accomplish the cost down. According to the present invention, the piston type compressor comprises a housing including a crank chamber and a cylinder block. A cylinder bore is formed in the cylinder block. A piston is accommodated in the cylinder bore so as to reciprocate. The piston is operatively connected to the cam plate. The piston reciprocates accompanying with rotation of the drive shaft so that drawing and discharging of a refrigerant is performed. A rotation preventing portion is formed on the piston, and a groove facing the rotation preventing portion so as to have clearance is formed on an inner circumferential surface of the crank chamber. By means of the abutment of the rotation preventing position with the groove, the rotation of the piston is prevented. The groove is formed to have draft smaller than that of other portions in the casting forming process.

摘要： A torque limiting mechanism for transmitting power from an external drive source to the drive shat of a compressor. A pulley, which is coupled to the external drive source, has elastic members. A hub, which is attached to the drive shaft, has engaging portions. A coupler member is located between the pulley and the hub. The coupler member is engaged with the elastic members and with the engaging portions such that power is transmitted from the pulley to the hub. The urging members urge the coupler member such that the coupler member is disengaged from the engaging portions. When power is transmitted from the pulley to the hub, the elastic members maintain the coupler engaged with the elastic members and the engaging portions. When load generated due to power transmission exceeds a predetermined level, the elastic members are deformed such that the coupler member is disengaged from the elastic members. When disengaged from the elastic members, the coupler member is disengaged from the engaging portions.

摘要： A controller for a compressor selects a control procedure from a normal displacement control procedure and a temporary control procedure based on information detected by a detector. When the normal displacement control procedure is selected, the controller sends a current, the value of which is based on the detected information, to an electromagnetic actuator. When the temporary displacement control procedure is selected, the controller sends a current having a specific value to the actuator to maximize a target compressor suction pressure. When switching from the temporary displacement control procedure to the normal displacement control procedure, the controller changes the value of the current supplied to the electromagnetic actuator according to a pattern, which is determined based on the detected information, over a predetermined period. The controller determines the pattern of the current variation during the predetermined period based on the suction pressure during or at the end of the temporary displacement control procedure.

摘要： A control valve is located in a variable displacement compressor used in a refrigerant circuit. The control valve operates such that the pressure difference between two pressure monitoring points in the refrigerant circuit seeks a predetermined target value. A controller determines the target value of the pressure difference in accordance with external information that represents the required cooling performance. The target value of the pressure difference is represented by a duty ratio applied to the control valve. When the acceleration pedal is pressed beyond a predetermined level, the controller limits the duty ratio. Therefore, the compressor torque does not hinder quick vehicle acceleration. Also, the cooling performance is not lowered unless it is necessary.
摘要翻译：控制阀位于用于制冷剂回路的可变排量压缩机中。控制阀的操作使得制冷剂回路中的两个压力监测点之间的压力差寻找预定的目标值。控制器根据表示所需冷却性能的外部信息确定压力差的目标值。压力差的目标值由施加到控制阀的占空比表示。当加速踏板被按压超过预定水平时，控制器限制占空比。因此，压缩机扭矩不会妨碍车辆加速。此外，除非有必要，否则冷却性能不会降低。

摘要： A control valve for a variable displacement compressor in refrigerant circuit permits the compressor displacement to be accurately controlled regardless of the thermal load on an evaporator. The refrigerant circuit includes a high pressure pipe, which extends between a discharge chamber of the compressor and a condenser. A first pressure monitoring point is located in the discharge chamber. A second pressure monitoring point is located in the high pressure pipe. A supply passage connects the second pressure monitoring point with a crank chamber of the compressor. The control valve is located in the supply passage and adjusts the opening size of the supply passage in accordance with the difference between the pressure at the first pressure monitoring point and the pressure at the second pressure monitoring point. The control valve includes a solenoid for determining the target value of the pressure difference. The control valve operates to maintain the determined target value.

摘要： A control valve controls the displacement of a variable displacement type compressor. The compressor includes a crank chamber, suction chamber, a bleed passage, and a supply passage. The control valve has a supply side valve, a transmission rod, and a relief side valve. The transmission rod connects the relief side valve with the supply side valve. The relief side valve includes a passage chamber constituting part of the bleed passage. The passage chamber is separated into a first area, which is connected to the crank chamber, and a lower area, which is connected to the suction chamber. A pressure sensing member moves the relief side valve body in accordance with the pressure in the upper area. The effective pressure receiving area of the sensing member is substantially equal to the cross sectional area of the passage chamber that is sealed by the relief side valve body.
