Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2016/016917
Kind Code:
A1
Abstract:
This scroll compressor is provided with: a compression mechanism which comprises an orbiting scroll and a fixed scroll that meshes with the orbiting scroll to form a compression chamber; a frame which is positioned on the side of the orbiting scroll opposite of the fixed scroll, which is attached to the fixed scroll such that the frame and the fixed scroll together sandwich the orbiting scroll, and on which a primary bearing is formed; and a frame auxiliary member which is mechanically fastened from the bottom of the frame and is welded at the outer periphery to an airtight container. Since the scroll compressor is provided with a frame auxiliary member which is mechanically fastened from the bottom of the frame and is welded at the outer periphery to the airtight container, even when using an aluminum material in the compression mechanism, it is possible both to fix the compression mechanism to the airtight container and to suppress welding deformation of the compression mechanism.
