スクロール型圧縮機
Document Type and Number:
Japanese Patent JP4398539
Kind Code:
B2
Abstract:
A scroll-type compressor includes a fixed first scroll member, an orbital second scroll member, and a ball coupling provided as a rotation preventing mechanism for the second scroll member. The ball coupling has a pair of integrally formed rolling ball regulating plates and a plurality of balls disposed therebetween. The ball coupling is assembled in the compressor at a condition in that an axial preload is provided. The axial preload is set more than an axial force given by the balls to the rolling ball regulating plates during operation of the compressor for correcting deformation of the rolling ball regulating plates. When the compressor is assembled, an axial gap between the first and second scroll members may be properly adjusted. After the assembly and during the operation of the compressor, the behavior of balls may be stable.
