PURPOSE: To prevent breakage of flexible plates due to the abnormal compression of lubricating oil or the like invading inbetween both end bearings and improve the reliability of the compressor by a method wherein oil discharging holes for releasing the lubricating oil are provided between the flexible plates, being pinched between both end faces of a cylinder and both end bearings, and the end bearings.
CONSTITUTION: The flexible plates 3, 7 are consisting of a thin elastic material and are pinched between both end faces of the cylinder 8 and both end bearings 2, 6 while the plates 3, 7 are arranged so as to be capable of being deflected toward the cylinder chamber 8 side having comparatively a low pressure by the high pressure of oil, with which a case 101 is filled, acting through the oil discharging holes 21, 21 and the penetrating parts of a crank shaft 1. The oil discharging holes 21 are provided on the end bearings 2, 6 and one ends thereof are opened at the sides of the flexible plates 3, 7 which the other ends thereof are communicated with a space in the enclosed case 101. According to this constitution, the breakage of the flexible plates 3, 7 due to the abnormal compression of the lubricating oil or the like invading inbetween the end bearings 2, 6 may be prevented and the reliability of the compressor may be improved.
