摘要： An electric compressor (10) is equipped with a motor chamber (27) provided in a suction pressure region. The motor chamber (27) is adjacent to an inverter accommodation chamber (101) with a first housing (24) therebetween, and a cooling hole (130) extending from the motor chamber (27) toward the inverter accommodation chamber (101) is formed through the first housing (24). The cooling hole (130) is a through-hole passing through the first housing (24). A cooling medium in the motor chamber (27) flows into the cooling hole (130) and comes into contact with a heat transfer plate (110), thereby cooling the heat transfer plate (110) directly.

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 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.
摘要翻译：可变排量压缩机通过避免低效的条件有效地运行。压缩机使用执行外部负载控制程序的控制阀改变其排量。根据发送到控制阀的驱动信号的占空比Dt来确定用于控制位移的目标值。如果占空比Dt等于或大于预定参考值DJ，则允许位移相应于占空比Dt而变化。如果占空比Dt小于参考值DJ，则通过占空比控制程序的可变排量控制被暂停。在这种情况下，压缩机以无效占空比（Dt = 0）或最小排量运行。
