Abstract: A scroll compressor including a shaft configured to be rotated by a drive source; an eccentric bush having a recess portion into which the shaft is inserted, an eccentric portion eccentric to the shaft, and a balance weight for balancing a rotation; an orbiting scroll configured to be orbited by the eccentric portion; and a fixed scroll configured to be engaged with the orbiting scroll, and a rotational clearance is formed between an outer peripheral surface of the shaft and an inner peripheral surface of the recess portion, and the eccentric bush is formed to be capable of performing a swing motion relative to the shaft in a range of the rotational clearance based on a drive pin configured to connect the shaft and the eccentric bush, and an adjusting mechanism configured to reduce the swing motion of the eccentric bush is disposed between the shaft and the eccentric bush.

Abstract: Variable displacement swash plate type compressor includes casing, rotating shaft, swash plate, piston, and inclination adjustment mechanism with first flow path connecting discharge chamber with crankcase and second flow path connecting crankcase with suction chamber to adjust inclination angle of the swash plate. An orifice hole decompressing fluid passing through the second flow path is formed in the second flow path. An orifice control mechanism controlling effective flow cross-sectional area of the orifice hole is formed on the second flow path. The orifice hole and control mechanism are formed to increase differential pressure in the crankcase and suction chamber, the effective flow cross-sectional area increases, and with further differential pressure increase it becomes a second area larger than zero and less than the first area. Achieved is rapid control of refrigerant discharge amount and prevention of reduction in compressor efficiency with reduction of time to switch to the maximum mode.
