    • In a wobble plate type compressor having a wobble plate that converts a rotational motion of a rotatable drive plate having a variable angle of inclination to a linear reciprocating motion of a piston, a method of controlling the wobble plate type compressor to control a displacement of the compressor by changing an angle of inclination of the wobble plate according to a pressure difference between a pressure in a crankcase chamber acting on one side of the piston and a suction pressure acting on the other side of the piston. A solenoid-operated control valve is disposed in a pressure control passage extending from a discharge chamber to the crankcase chamber. The control valve is opened and closed to control the above-mentioned pressure difference, thus controlling the angle of inclination of the wobble plate. An opening of the control valve is increased during a period in which the displacement of the compressor is to be reduced, according to a displacement rapid reduction command signal. In an initial stage of this period, the opening of the control valve is made temporarily wider than in the remaining period.
    • 在具有将具有可变倾斜角度的可旋转驱动板的旋转运动转换为活塞的直线往复运动的摆盘的摆盘式压缩机中,控制摆动板式压缩机的方法, 通过根据作用在活塞的一侧的曲轴箱室内的压力与作用在活塞的另一侧的吸入压力之间的压差来改变摆盘的倾斜角度来进行压缩。 电磁操作控制阀设置在从排出室延伸到曲轴箱室的压力控制通道中。 控制阀打开和关闭以控制上述压力差,从而控制摆盘的倾斜角度。 根据位移快速减速指令信号,在要减小压缩机的位移的期间,控制阀的开度增加。 在这个时期的初始阶段,控制阀的打开暂时比剩余时间宽。
