Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/081845
Kind Code:
A1
Abstract:
In the present invention an oil passage (51) is formed so as to communicate with an oil reservoir (50) and a compression chamber suction-side space (25s) formed inside a casing (10), and a plunger (33) of a suction volume adjustment mechanism (30) is arranged midway along the oil passage (51), and is equipped with a switching unit (65), which closes off the oil passage (51) and disconnects the oil reservoir (50) and the suction-side space (25s) when the suction-closing switching position is a first position, and opens the oil passage (51) and enables the oil reservoir (50) and the suction-side space (25s) to communicate when the suction-closing switching position is a second position for which the suction volume is less than that of the first position. Thus, a decrease in the performance of the compressor can be suppressed, and the outflow of oil can be suppressed.
