摘要： A pump includes a piston block defining piston bores, and pistons disposed in the piston bores. A swash device defines a swash bore about a swash central axis (CSW) and a swash rotation axis (CR). A pivotal connection pivotally connects each of the pistons to the swash device for rotation about a connection pivot point during relative movement between the swash device and the piston. The connection pivot points are aligned in a plane (P). A shaft supported by the housing passes through the swash bore and defines a shaft central axis (CSH). A hinge assembly pivotally supports the swash device about a hinge axis (CHI) disposed on the opposite side of the plane (P) from the piston block. The swash rotation axis (CR) of the swash device is offset from the plane (P) away from the hinge axis (CHI) and is radially offset from the swash center axis in a direction toward the hinge axis (CHI).

摘要： A variable displacement compressor with a discharge pressure compensated suction shutoff valve (SSV). The SSV prevents noise generated at low refrigerant flow rates by a suction valve from propagating out of the compressor and to an air conditioner evaporator by variably restricting a fluid communication with the suction valve. The SSV is configured so the variable restriction is increased correspondingly with the discharge pressure if the discharge pressure is less than a threshold that is an indicator of low refrigerant flow rates, and the restriction is decreased if the discharge pressure is greater than the threshold.
