Suction duct with stabilizing ribs

摘要

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.

主权项

1. A compressor for compressing a fluid, comprising:
a housing having an inlet for receiving the fluid and an outlet returning the fluid; a compressor mechanism adapted to compress a fluid toward the outlet, the compressor mechanism housed in the housing; a drive unit comprising an electric motor having a rotor and a stator, the drive unit operatively connected to the compressor mechanism via a drive shaft for driving the compression mechanism to compress fluid; a lower bearing mount receiving a bottom end of the drive shaft; a suction duct in the housing having an inlet region arranged over the inlet of the housing, the suction duct comprising a ring body having at least one channel facing the housing forming at least one flow passage therebetween, wherein the suction duct is situated in an annular cavity formed between a bottom portion of the stator and the lower bearing mount; and at least one stabilizing structure acting between the suction duct and the housing in the at least one channel.
