Abstract

A variable displacement swash plate type compressor includes a first and a second valve body, and a suction and a bleed window. An open degree of the suction window is minimized by the first valve body and an open degree of the bleed window is maximized by the second valve body when a suction pressure is lower than a predetermined suction pressure and a crank chamber pressure is higher than a control pressure. The open degree of the suction window is increased and the open degree of the bleed window is maximized when the suction pressure is higher than the predetermined suction pressure and the crank chamber pressure is higher than the control pressure. The open degree of the suction window and the open degree of the bleed window are decreased when the crank chamber pressure is lower than the control pressure.
