Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2021/038614
Kind Code:
A1
Abstract:
A scroll compressor includes: an autonomously-movable tooth that is inserted into an insertion hole penetrating through a fixed scroll and constitutes a part of fixed spiral teeth, the autonomously-movable tooth being configured to autonomously move up and down in the insertion hole; and a magnet that is provided on the fixed scroll and attracts the autonomously-movable tooth in the insertion hole toward a side away from a swing scroll so that an end face of the autonomously-movable tooth is moved away from a swing base plate. The autonomously-movable tooth autonomously moves up and down in the insertion hole according to a magnitude relation between: a force applied to the autonomously-movable tooth by a high pressure; and a combined force of a magnetic force of the magnet and a force applied to the autonomously-movable tooth by a low pressure. A suction volume is adjusted by switching between an abutting state in which the end face of the autonomously-movable tooth is flush with end surfaces of the fixed spiral teeth other than the autonomously-movable tooth and a spaced state in which the end face of the autonomously-movable tooth is not flush with the other end surfaces and is away from the swing base plate.
