Title:
SEALED COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2010/070851
Kind Code:
A1
Abstract:
A sealed compressor capable of avoiding a backflow of oil when the compressor is brought to a stop.
A compression mechanism (4) is provided at the lower part of a gas containing space (14) inside a sealed container (3). An oil supply path (11) supplies oil from an oil sump section (32) to the gas containing space (14) and to a sliding portion of the compression mechanism (4) of a compression space (24). In addition, the oil supply path (11) communicates with a second space (26) located on the rear side of a piston relative to the gas containing space (14) and the suction chamber (24). A second route (12) is a route different from the oil supply path (11). The second route (12) can make a gas medium flow from the gas containing space (14) to the second space (26). The path resistance when the gas medium flows in the second route (12) is less than the path resistance when the gas medium flows in the oil supply path (11).
