COMPRESSOR

WIPO Patent Application WO/2005/111417

A1

[PROBLEMS] To efficiently supply a lubricating oil separated by an oil separator, provided in a delivery channel, to a shaft sealing device and a sliding bearing. [MEANS FOR SOLVING PROBLEMS] A compressor comprising a driving shaft (7) rotated by an externally transmitted rotational force, a swash plate (21) made to pivot by the driving shaft (7), and a piston (17) reciprocated by the swash plate (21), wherein an oil separator (31) is provided in a delivery channel (35) and a lubricating oil is separated by the oil separator (31). The separated oil is introduced to a first isolation space (50) defined by a sliding bearing (14) provided at the rear of the driving shaft (7) to lubricate the sliding bearing (14). Subsequently, the oil is introduced through a lubricating oil introduction channel (51) to a second isolation space (60) defined by a shaft sealing device (11) and a sliding bearing (12) provided at the front of the driving shaft (7), lubricating the shaft sealing device (11) and the sliding bearing (12). Furthermore, the lubricating oil is introduced by a pressure difference to a crank chamber (4) from a circulation flow channel (61) formed between the second isolation space (60) and the crank chamber (4).
