<p><P>PROBLEM TO BE SOLVED: To provide a compressor always ensuring an oil film in a part requiring lubrication, and improving durability. <P>SOLUTION: This compressor (2) compresses a CO<SB>2</SB>refrigerant sucked from a refrigerating circuit (61) through a suction chamber (50), and delivers compressed refrigerant gas to a delivery chamber (52) according to the regulation of the pressure of the CO<SB>2</SB>refrigerant including lubricating oil in a crank chamber (28). The compressor is provided with a housing (6), a cylinder bore (24) formed in the housing and compressing the refrigerant, a piston (26) reciprocating in the cylinder bore, and a pore (70) formed in the housing and having a shape to introduce the refrigerant in the suction chamber to the crank chamber. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
