IPC: F04B39/00
Filed: 1986-03-12
Abstract: PURPOSE:To make it possible to maintain silencing effect by forming a cup- shaped discharge muffler with shape memory alloy to produce an appropriate clearance when the muffler is cold between a peripheral part of a lower bearing and a boss part and when it is hot to close the clearance between the two parts so that the two parts are brought to a drawn fit condition. CONSTITUTION:Clearance between a lower bearing 11 of a closed rotary type compressor and a cup-shaped discharge muffler 12 made of shape memory alloy is closed when the said muffler is hot to produce a drawn fit condition between the lower bearing 11 and the cup-shaped muffler 12. This can eliminate pressing-in process of the cup-shaped muffler when manufacturing the compressor. When cold-starting the compressor, a large amount of liquid refrigerant discharged out of a compression chamber is let out through a clearance formed between the said parts 11 and 12 to ease abnormal temperature rise in a chamber of the muffler 12. Further, since the lower bearing 11 and the cup-shaped discharge muffler 12 are in a drawn fit condition without clearance during normal operation, silencing effect as before can be obtained.
