Abstract

PURPOSE:To reduce the size of a rotary type enclosed compressor, by forming an outlet port of a discharge passage at the middle section in an inner chamber of a silencing means, and preventing production of standing resonance in the circumferential direction in the cross sectional plane. CONSTITUTION:An outlet port 15 is disposed at the middle section of the height of a silencing means 16 so as to prevent production of resonance in an inner chamber of the silencing means 16 in the direction of its height. Further, since a discharge passage 14 is formed in a cylinder 12 and the silencing means 16 is disposed in an upper bearing 5, it is enabled to omit superfluous piping members and to reduce its size. Therefore, a rotary type enclosed compressor can be made compact.

Therefore, in order to solve this drawback, the present invention proposes an effective and compact dissipation device, which enables miniaturization of the rotary hermetic compressor and significantly improves productivity.

A discharge passage communicating with the cylinder via a discharge valve is provided in the cylinder shaft, a silencer is provided inside the bearing of the cylinder shaft, and an outlet hole of the discharge passage is disposed in the center of the inner chamber of the silencer. This is what I did.

するものである。With this configuration, the present invention has the outlet hole of the discharge passage disposed in the center of the inner chamber of the muffler, so that the standing resonance in the cross-sectional circumferential direction that occurs in the inner chamber of the muffler is generated. It is possible to prevent noise from occurring in the height direction of the internal chamber of the silencer, and because the discharge passage is provided on the cylinder shaft and the silencer is installed inside the bearing, there is no need to worry about unnecessary piping parts. This has the advantage that the structure can be made compact without any problems, and assembly can be simplified.
