Abstract
A refrigerant compressor suitable for use in refrigerators, air conditioners, heat pumps or the like apparatus. The refrigerant compressor has a closed casing which encases a driving electric motor section and a compressor section constructed as a unit. The compressor section has a substantially horizontal crank shaft consisting of a main shaft portion fixed to one end of the rotor of the driving motor, an eccentric portion rotatably carrying a rotary piston and an end journal portion. The lubrication system of this compressor has a passage means for introducing a lubricating oil to various parts requiring lubrication, and a lubricator adapted to supply the lubrication oil to the passage means. The passage means includes a peripheral oil groove formed in the portion having crank shaft of the minimum eccentricity and connected at its one end to a peripheral oil groove formed in the main shaft portion and at its other end to a peripheral oil groove in the journal portion of the crank shaft. The lubricator includes a curved oil pipe fixed at its one end and immersed at its other end in the lubricating oil collected in the closed casing, and a coiled spring rotatably received by the oil pipe and connected at its one end to the journal portion of the crank shaft while the other end is immersed in the lubricating oil through the end opening of the oil pipe.
