LUBRICATION OIL FEED APPARATUS FOR COMPRESSOR

摘要

PURPOSE: A lubrication oil feed apparatus for compressor is provided to prevent solid friction caused due to the mixture of the lubrication oil and gas, while achieving improved reliability of system by preventing lubrication oil from being discharged into the system. CONSTITUTION: An apparatus is characterized in that a stepped portion(13'a) is formed at a passage(13') of an eccentric shaft. The stepped portion serves to separate a lubrication oil(10) from a gas, and permit the separated lubrication oil to be fed to an oil hole(14) and the separated gas to flow along the passage of the eccentric shaft. An oil separation mesh equipped with a mesh filter for separating the lubrication oil and gas, is installed within the stepped portion. The mesh filter is supported by a blocking plate for blocking the lubrication oil, and the blocking plate has a communicating port for allowing the lubrication oil separated by the mesh filter to be discharged to the oil hole through the centrifugal force of the eccentric shaft.
