scroll compressor
Abstract
Abstract PURPOSE:To seal up a gap between end faces with magnetic fluid for reducing refrigerant leakage from a compressed space by enclosing magnetic fluid containing magnetized powder in a seal groove provided on the end face of lap portions of both scroll. CONSTITUTION:Lap portions 2c, 2d of fixed and movable scrolls 2a, 2b are provided on the respective end faces with scroll-shaped seal grooves 2f, 2g respectively. Magnets 2k, 2l are respectively disposed in the seal grooves 2f, 2g. Magnetic fluid 23 having volume somewhat larger than that of seal groove is enclosed in the respective seal grooves 2f, 2g to fill a gap C. The whole magnetic fluid 23 works as if it is a mass by the adhesion between powder in the magnetic fluid 23 and the fluid to seal up the gap C.
