    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).

    摘要： A variable capacity wobble plate type compressor provided with a reciprocatory piston mechanism for compressing a refrigerant gas and discharging the compressed refrigerant gas, a drive shaft driven by an external drive source to allow an assembly of angularly variable drive and wobble plates to reciprocate the reciprocatory piston mechanism, a coil spring mounted on the drive shaft for applying a biasing force to the assembly of drive and wobble plates toward a predetermined angularly inclined position, and annular spring support members for supporting the opposite ends of the coil spring so that the coil spring is not in contact with the outer surface of the drive shaft, to thereby prevent an abrasion of the coil spring and the drive shaft when the coil spring is contracted and expanded during the operation of the compressor.

    摘要： In a wobble plate type compressor having a wobble plate that converts a rotational motion of a rotatable drive plate having a variable angle of inclination to a linear reciprocating motion of a piston, a method of controlling the wobble plate type compressor to control a displacement of the compressor by changing an angle of inclination of the wobble plate according to a pressure difference between a pressure in a crankcase chamber acting on one side of the piston and a suction pressure acting on the other side of the piston. A solenoid-operated control valve is disposed in a pressure control passage extending from a discharge chamber to the crankcase chamber. The control valve is opened and closed to control the above-mentioned pressure difference, thus controlling the angle of inclination of the wobble plate. An opening of the control valve is increased during a period in which the displacement of the compressor is to be reduced, according to a displacement rapid reduction command signal. In an initial stage of this period, the opening of the control valve is made temporarily wider than in the remaining period.
