    Abstract: A control valve according to one embodiment includes a shaft that transmits the solenoidal force to a valve element. A solenoid includes a bottomed sleeve into which the pressure of refrigerant is introduced, a core secured coaxially to the sleeve, a plunger, contained in the sleeve on its bottom side, which is displaceable integrally with the shaft in a direction of axis line, a first spring that applies the biasing force in a valve opening direction to the shaft, a second spring that applies the biasing force in a valve closing direction to the plunger, and a shaft support member, which is press-fitted such that the shaft support member is secured to an inner wall of the sleeve near its bottom portion. The second spring is set between the shaft support member and the plunger. One embodiment therefore ensures high pressure resistance at a mounting part where a control valve is mounted in a variable displacement compressor.

    Abstract: A compressor includes a housing, a cylinder block, a valve plate, a discharge valve forming plate and a retainer gasket. The discharge valve forming plate includes a discharge valve, a connecting portion and a discharge valve engaging portion. The discharge valve opens and closes the discharge port. A plurality of discharge valve support portions extends from the connecting portion to support the discharge valve. The discharge valve engaging portion extends from the connecting portion. The retainer gasket includes a retainer, a gasket and a retainer gasket engaging portion. The retainer restricts an opening and closing operation of the discharge valve. The gasket ensures airtightness between the housing and the cylinder block. The retainer gasket engaging portion is formed by bending a part of the retainer gasket. The discharge valve forming plate and the retainer gasket are positioned by connecting the discharge valve engaging portion and the retainer gasket engaging portion.

    Abstract: A compressor has suction reed valves each of which includes a fixation portion fixed to the valve base plate, a basal portion that extends from the fixation portion and is separable from the plate, and a valve flap extending from the basal portion toward the distal end to selectively open and close the suction port. Each suction port has a shape elongated in the width direction, which is orthogonal to the longitudinal direction. The width of the basal portion is greater than that of the suction port. Each valve flap includes an opening-closing portion facing the corresponding suction port and stoppers, which project from the ends in the width direction. The side edges in the width direction are continuous from the stoppers to the basal portion to gradually approach the suction port. The cylinder block has pairs of recessed retainers. The stoppers contact the retainers.

    Abstract: Lubricating performance and durability of a variable capacity compressor are secured. A first communication hole 202 is formed to be close to a penetration bolt 201a at an upstream side in a rotational direction, the penetration bolt 201a is disposed outside a rotation trajectory of a rotating member such as a swash plate in a front housing 101, and a second communication hole is formed to be close to an upper penetration bolt 201b at a downstream side in a rotational direction. The first and second communication holes are formed by penetrating a peripheral wall of the front housing 101, a storage chamber 206 storing oil in refrigerant is arranged outside the front housing 101 by communicating with an inner space of the front housing 101 through the communication holes, and while refrigerant in the storage chamber 206 is returned to the inner space from the second communication hole 203, oil in refrigerant received by contacting an upstream side of a first penetration bolt 201a is stored in the storage chamber 206 from the first communication hole 202, and as a result, as a rotational speed is increased, a storage amount is increased.
