The capacity of a refrigerant compressor comprising a wobble plate assembly (15, 16, 17) for reciprocating pistons 22 in cylinders (32) is varied by adjusting the slant angle of the wobble plate. The slant angle is controlled by variation of the pressure level in a chamber (13) in which the wobble plate is disposed. The chamber pressure is controlled by an intermittently operated electromagnetic valve (41) which controls communication between the chamber (13) and a suction chamber 35. The valve operates in response to pulsatory signals having a variable duty ratio. A comparator emits the signals in response to input signals from a delta wave oscillator and a micro computer. <IMAGE> |
