Title:
REFRIGERANT COMPRESSOR AND VAPOR-COMPRESSION REFRIGERATION CYCLE DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2016/181559
Kind Code:
A1
Abstract:
A second compression mechanism (20) in a refrigerant compressor (100) has a cylinder deactivation mechanism (50) that switches between compression operation and cylinder deactivation operation. The cylinder deactivation mechanism (50) comprises a magnetic body (53) that causes an attractive magnetic force to be generated that attracts a second vane (24) in a direction away from a second piston (23). The magnetic body (53) is provided facing a vane rear chamber (25) and comprises a surface (53a) facing a rear end section (24b) of the second vane (24). Oil supply flow paths (55a, 55b) that supply lubricating oil stored inside a sealed container (3) to the vane rear chamber (25) are provided in the second compression mechanism (20), said oil being supplied along an upper surface (53b) and a lower surface (53c) of the magnetic body (53) that have a different orientation to the surface (53a) of the magnetic body. Part of an inner wall surface of the oil supply flow paths (55a, 55b) comprise the upper surface (53b) and the lower surface (53c).
