Document Type and Number:
WIPO Patent Application WO/2019/176724
Kind Code:
A1
Abstract:
[Problem] One purpose of the present invention is to provide a reliable swash plate-type compressor in which generation of noise at a thrust bearing in a swash plate-type compressor is suppressed. Another purpose of the present invention is to provide a swash plate-type compressor that has a reduced number of components and is provided with a thrust bearing, which is a simple mechanism not associated with adverse effects during assembly. [Solution] The present invention provides a single-sided swash plate-type compressor 1 in which a plain bearing 201, 202 is adopted as a thrust bearing, the plain bearing being fixed to a front housing 5 or a rotor 191. The plain bearing 201, 202 is made of a resin, a metal sintered material, or a ceramics sintered material. The plain bearing 202 has a gradient α such that the thickness of the plain bearing 202 corresponding to the top dead center of a piston 25 is decreased and the thickness of the plain bearing 202 corresponding to the bottom dead center of the piston 25 is increased.
