DEVICE FOR LUBRICATING SHAFT BEARING OF COMPRESSOR

摘要

PURPOSE: A lubricator of a shaft bearing for a compressor is provided to improve the productivity by equipping with a lubricant passage in a valve device. CONSTITUTION: Lubricating oil to be mixed with an actuating fluid is supplied to a shaft bearing(7) through a passage via a lubricating hole(4c) in a cylinder(4). The passage comprises a lubricant guiding hole(37) of an inlet lid(30) and a supplying passage(41) of a valve plate(31). The passage is connected up to a lubricating hole(4c) and an accepting hole(4b) of the cylinder(4). The shaft bearing is assembled with the cylinder(4). By simply forming the supplying passage, the productivity is improved and the lubricating oil is smoothly supplied to the shaft.
