Title:
HOUSING SEAL STRUCTURE AND FLUID MACHINE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2018/016422
Kind Code:
A1
Abstract:
Provided is a housing seal structure that better prevents housing corrosion of a seal structure using an O ring between housings. In the housing seal structure, an O ring 62 seals between a joint surface 57 of a fixed scroll 24 and a joint surface 59 of a front housing 4 which are joined to each other via a shim 15. The shim 15 is composed of a metal base material and a metal film, which is formed on the surface of the base material and is softer than the base material. The shim 15 is positioned outside the O ring 62 and provided over the entire periphery. The metal film of the shim 15 has a thickness that can fill the surface roughness of the fixed scroll 24 and the front housing 4 on the joint surfaces 57, 59.
