摘要： A variable displacement type swash plate compressor that prevents a drive shaft from moving axially when the difference between a crank chamber pressure and a cylinder bore pressure becomes excessive. A hinge mechanism has a support arm extending from a lug plate and a guide pin extends from a swash plate. The head portion of the guide pin fits in a guide hole formed in the support arm. A cutaway surface is formed in a part of the support arm that defines the guide hole. The cutaway surface forms a clearance in the hinge. The clearance permits the swash plate to move without pulling the drive shaft.

A front uppermost and a rear uppermost layer of the swash plate are formed of a sprayed coating of, for example, a copper-base material and the rear uppermost layer is coated by a solid lubricant layer containing a solid lubricant, such as molybdenum disulfide, at least in a part of the solid lubricant. The thickness of the solid lubricant layer is measured and controlled by using the surface of the front layer as a reference plane.

摘要： A variable displacement compressor includes a cylinder block and a valve plate connected to the cylinder block. The cylinder block has cylinder bores and a central supporting hole. A piston is housed in each cylinder bore to compress gas. A swash plate is connected to the pistons to convert rotation of the drive shaft into reciprocation of the pistons. A cylindrical body is housed in the supporting hole. A coil spring located in the supporting hole presses the cylindrical body toward the swash plate. The cylindrical body moves axially as the swash plate is inclined. When the swash plate is minimally inclined, the valve plate receives force from the swash plate through the cylindrical body. Therefore, axial forces from the swash plate are not exerted on the drive shaft.

摘要： A swash plate is mounted on a drive shaft disposed in a housing having a gas suction chamber in such a way that the swash plate is rotatable integrally with the drive shaft. A plurality of cylinder bores are formed around the drive shaft, extending along the drive shaft. Disposed in each cylinder bore is a piston, which reciprocates between top and bottom dead centers by undulating movement of the swash plate caused by rotation of the drive shaft. A compression chamber where gas is compressed by the reciprocal movement of the piston is defined in each cylinder bore. Provided between the drive shaft and the swash plate is a mechanism for altering an angle of the swash plate with respect to the axis of the drive shaft to change a reciprocal stroke of the piston to thereby control compression displacement. A rotary valve is provided at the drive shaft to be rotatable integrally with the drive shaft. The rotary valve has a passage for permitting uncompressed gas to move to each compression chamber from the suction chamber in synchronism with the reciprocal movement of the piston during rotation of the rotary valve before the piston reaches the bottom dead center. The compressor further comprises a mechanism for forcibly changing the timing at which the piston substantially reaches the top dead center in accordance with an inclined angle of the swash plate.

摘要： In a swash-plate compressor, pistons are slidably received in cylinder bores. A drive shaft is extended through a crank chamber, and is rotated through an electromagnetic clutch means associated therewith. A conversion mechanism is provided on the shaft for converting a rotational movement of the shaft into a reciprocation of each piston in the corresponding cylinder bore such that a suction stroke and a discharge stroke are alternately executed therein. A fluid is introduced from a suction chamber into the bore during the suction stroke, and during the compression stroke, the fluid is compressed in and discharged from the bore into a discharge chamber. The conversion mechanism is constituted such that a stroke length is shortened in response to an increase of a pressure in the crank chamber, and vice versa. A first passage communicates the crank with the suction chamber, and a second passage communicates the crank chamber with the discharge chamber. A control valve is provided in one of the first or second passage, and is magnetically actuated by the clutch for controlling the pressure in the crank chamber such that the piston stroke can be minimized whenever the clutch is electrically deenergized.

摘要： A compressor has a piston (11) that reciprocates between a top dead center and a bottom dead center in a cylinder bore (2a) by means of a driving body (9) mounted on a rotary shaft (6) in a crank chamber (5) during the rotation of the rotary shaft (6). The piston (11) has an outer circumferential surface that slides against an inner circumferential surface of the cylinder bore (2a). The outer circumferential surface of the piston (11) is provided with a groove (17; 44; 46) extending in the direction of an axis (S) of the piston (11). During reciprocation of the piston (11), lubricating oil adhered to the inner circumferential surface of the cylinder bore (2a) is collected in the groove (17; 44; 46). When the groove (17; 44; 46) is exposed to the inside of the crank chamber (5) from the cylinder bore (2a) during the reciprocation of the piston (11), the lubricating oil in the groove (17; 44; 46) is supplied to the inside of the crank chamber (5). The lubricating oil lubricates the driving body (9) and other parts in the crank chamber (5).
