Abstract:
A hermetic compressor comprising:a motor portion used as a power source;a mechanical portion including a crankshaft, a piston, and a cylinder driven by said motor portion;an enclosed container for housing said motor portion and said mechanical portion and for storing lubricant;a suction passage installed on said mechanical portion so as to communicate said cylinder with said enclosed container; anda position adjustment mechanism for adjusting an opening end in said suction passage into said enclosed container;wherein said position adjustment mechanism disposes said opening end on at least one of three planes:(1) a first plane which is substantially orthogonal to a first line segment at the center point of said first line segment passing through the center of gravity of a plane having a substantially maximum cross-sectional area on the horizontal cross-section of said enclosed container, said first line segment being at a position wherein the distance between the inner walls of said enclosed container is minimum,(2) a second plane which, on the horizontal plane including said first line segment, passes through the center point of a second line segment between the inner wall surfaces of said enclosed container, said second line segment being substantially orthogonal to said first line segment, and which is substantially orthogonal to said second line segment, or(3) a third plane which passes through the center point of a third line segment having the maximum distance between the upper inner wall surface of said enclosed container and said lubricant surface in the vertical direction, and which is substantially orthogonal to said third line segment.
