Patent ID: 8096794

Claim:
A compressor constructed by enclosing a compression mechanism unit for compressing a refrigerant in a housing whose interior is held at a lower pressure than a discharge pressure, said compressor comprising: an oil separator for separating oil from said refrigerant compressed by said compression mechanism unit; and a high-pressure oil storage chamber, located adjacent to said compression mechanism unit, for storing said oil separated by said oil separator, wherein at least a portion of said oil separator is provided outside said housing, wherein said high-pressure oil storage chamber is constructed from a pressure-resistant container whose wall thickness is greater than an outer wall forming said housing accommodating said compression mechanism unit, and within said housing, a space in which oil is not filled is formed between said compression mechanism unit and said pressure-resistant container forming said high-pressure oil storage chamber, wherein a partition wall forming a side wall of said high-pressure oil storage chamber at a side thereof that faces said compression mechanism unit is provided so as to form a space between said compression mechanism unit and said high-pressure oil storage chamber within said housing, and a portion of an oil return passage through which the oil stored in said high-pressure oil storage chamber is fed back to said compression mechanism unit is constructed as an oil feed pipe which is disposed outside said housing, wherein said partition wall is joined to said housing on an interior side thereof, and wherein said partition wall has a cross-sectional shape curved inwardly into said high-pressure oil storage chamber.
