Scroll type compressor with axially supported movable scroll

摘要

A scroll type compressor having movable and fixed scrolls forming a working chamber with a movable scroll supporting arrangement to prevent tilting of the movable scroll into the fixed scroll thereby making it possible to extend the axial length of the scrolls. A main supporting plate is fixed on a housing between two other supporting plates which are spacedly fixed on the movable scroll, or vice versa. The other supporting plates press on the main supporting plate from both sides via ball bearings. When the movable scroll is about to tilt, the supporting plate arrangement prevents the movable scroll from tilting.
