Abstract

PURPOSE: To positively cool the lubricating oil by cooling the lubricating oil in a oil tank using a part of the refrigerant gas bypassed from the suction passage to the oil tank.
CONSTITUTION: The lubricating oil stored in an oil tank 11 is sucked up by an oil pump 4a provided at the bottom end of a crank shaft 4 and supplied to the sliding parts. The temperature of lubricating oil is raised at the sliding parts before returning into the oil tank 11. A cooling coil 12 is immersed in the oil contained in the oil tank. One end 12a of the cooling coil 12 is opening in a suction tube 9 directing against the direction of the flow of the refrigerant gas and the other end 12b is opening in the suction tube 7 perpendicularly to or along the direction of the flow of the refrigerant so that pressure difference is produced between the openings 12a and 12b. Consequently, the refrigerant gas flows from the opening 12a to the opening 12b through the cooling coil 12, thus effectively cooling the lubricating oil in the oil tank 11.
