Suction duct with adjustable diametric fit

Abstract

A suction duct for a compressor such as a scroll compressor may include a plastic ring body with a metal screen heat staked in a window of the ring body to filter refrigerant gas entering the motor cavity. The ring body may be in surrounding relation of the motor and resiliently compressed in the housing through intermittent contact with the inner housing surface to better seal around the inlet port. Oil drain channels and stabilizing ribs may be along the outside surface of the ring body.

Description

technical field [0001] With some embodiments relating to scroll compressors, the present invention relates generally to a compressor for compressing refrigerant, and more particularly to an apparatus for filtering fluid prior to entering a compressor assembly. Background technique [0002] A scroll compressor is a specific type of compressor used to compress refrigerant for equipment such as refrigeration, air conditioning, industrial cooling and freezing equipment, and / or other equipment that uses compressed fluids. Such prior scroll compressors are known, for example, in US Patent 6,398,530 to Hasemann, US Patent 6,814,551 to Kammhoff et al., US Patent 6,960,070 to Kammhoff et al., and US Patent to Kammhoff et al. Yes, all of these patents are assigned to Bitzer entities closely related to this assignee. The entire disclosures of US Patent Documents 6,398,530, 7,112,046, 6,814,551, and 6,960,070 are hereby incorporated by reference in their entireties, as this disclosure ...
