Abstract

PURPOSE:To lower the noise and reduce the amount of an oil flow without making the overall length of a compressor greater by providing an outlet valve inside a groove formed in an upper bearing and containing the groove by using a cover while forming a muffler room through opening of an oil return passageway inside the groove. CONSTITUTION:A groove 19 is formed in an upper bearing 14. An outlet valve 13 is provided inside the groove 19. An opening 20 for an oil return is provided in the groove at the farthermost place from the outlet valve 13 piercing through the upper bearing 14, a cylinder 16, and a lower bearing 15. Furthermore, the upper part of the groove 19 is covered by a cover 22 to form a muffler room. Thus, the outlet valve 13 is always in a state of being immersed in an oil flowing through it, leading to the lowering of the noise level generated by the hitting of the valve seat through a valve motion, and also reduction of other noise and the amount of the flowing oil since the vicinity of the valve 13 is just in the same state as is being covered within the muffler room.
