Abstract

PURPOSE:To seal a case to be enclosed simply and certainly so as to enhance a compression transfer efficiency by fitting both ends of a cylinder in a plurality of bearing members provided in a face-to-face relation in the case, and thereafter by sealing a high pressure side and a low pressure side inside of the case at the fitted members. CONSTITUTION:A compressor 10 is constructed by incorporating an electrically element 12 and a compression element 13 inside of an enclosed case 11. An electrically driven element 12 is composed of a startor 14, fixed on the inwall surface of the enclosed case 11, and a rotor 15 provided inside of the startor 14. On the other hand, the compression element 13 is constructed by opposing plural bearing members 16, 17 each other inside of the enclosed case 11, while by supporting both ends of a cylinder 19 on respective bearing circumferential members 20, 21 of the bearing members 16, 17. A piston 18 is provided in a cylinder 19, so that respective bearings 23, 24 protruded on both ends thereof are supported by respective bearing holes 25, 26 of the bearings 16, 17. A spiral groove 28 for winding a blade 27 thereon is formed on the outer circumference of the piston 18.
