Abstract: A multicylinder rotary compressor has a plurality of cylinders housing rolling pistons which are rotated inside the cylinders by a common crankshaft. Each cylinder has a separate suction pipe. At least one of the suction pipes has a check valve which may be closed to unload the cylinder to which the suction pipe is connected. The check valve has a housing and a slider which can slide inside the housing between an open position and a closed position. The check valve may be closed by introduction of high-pressure refrigerant gas into the space beneath the slider to push it to the closed position when a cylinder is to be unloaded. In another form of the invention, the check valve is closed by a spring made of a shape-memory alloy and a heater for heating the spring above a prescribed temperature at which the allow changes shape. When a cylinder is to be unloaded, the heater is turned on, and the shape-memory alloy deforms into a shape such as to force the slide to the closed position. Lubricating oil may be provided to an unloaded cylinder.

Abstract: A fluid pressure responsive member is shifted in accordance with the pressure differential between two lines either one of which can be a suction line with the other line being a discharge line of a reversible compressor. The fluid pressure responsive member has a pair of arcuate recesses formed therein which serve as secondary suction ports which provide fluid communication to the elliptical chamber from suction lines in accordance with the position of the fluid pressure responsive member. Because the porting is responsive to the pressure differential between the two lines, the changeover of the porting is automatic upon the reversal of the operation of the compressor.

Abstract: A rotary compressor which includes a rotor into which vanes are slidably provided, the rotor and vanes being rotatably mounted in a non-circular cylinder having side plates fixed to both sides thereof. The rotor, cylinder, and side plates define sealing spaces at respective ends of which are provided suction bores and discharge bores. Between the blades and also bounded by the rotor, side plates and cylinder are blade chambers which rotate with the rotor and vanes across the suction bores and discharge bores so that the pressure in the blade chambers during a suction stroke of the compressor utilizes a suction loss which is lower than the pressure of a refrigerant supply source to carry out suppression of the refrigerating capacity during high speed rotation of the rotor. The passages of communication from the suction bores to the blade chambers have effective areas which are smaller during the second half of each suction stroke than during the first half thereof, thereby obtaining an effective suppression of refrigerating capacity during high speed rotation of the rotor, while maintaining low torque at low speed and a high volumetric efficiency.

Abstract: In a scroll compressor, means for maintaining the motion of an orbiting plate in fixed angular relationship to a stationary plate and for modulating the capacity of the compressor. The orbiting and stationary plates include intermeshed wrap elements of similar spiral shape about an axis. A coupling ring is slideably disposed between the plates and sealingly encloses the wrap elements. Four slots are provided in the coupling ring, aligned at right angles to each other and spaced apart around its inner circumference. Three segments, extending outward from the wrap elements, sealingly engage these slots. The fourth slot is engaged by a sliding key attached to one of the plates. The segments separate a first and a second fluid inlet and cooperate with the slots in the coupling ring to constrain the orbiting plate's motion in fixed angular relationship to the stationary plate. Valves on the first and second inlets are provided to control the flow of fluid to be compressed into the separate inlet volumes defined by the segments, thereby modulating the compressor's capacity.
