Abstract
A variable displacement swash plate compressor includes a displacement control valve that is configured to change crank chamber pressure, and an opening adjusting valve that adjusts an amount of refrigerant sucked into a suction chamber. The opening adjusting valve includes a valve case, a first valve element, a second valve element, and an urging spring. The valve case has a valve seat on which the second valve element is seated. The valve seat regulates movement of the second valve element toward the first valve element. A sealing member is provided between an inner peripheral surface of the valve case that defines a second valve chamber and an outer peripheral surface of the second valve element to prevent refrigerant in the second valve chamber so that leakage between a bleed passage and a control passage is prevented.
