Embodiment Construction

[0026] The following description is merely exemplary in nature and is not intended to limit the present teachings, application, or uses.

[0027] The present teachings are suitable for incorporation in many different types of scroll and rotary compressors, including hermetic, open drive and non-hermetic machines. For exemplary purposes, a compressor assembly 10 is shown comprising a low side hermetic scroll refrigerant motor compressor 12, i.e., where the motor and compressor are cooled by suction air in a hermetic enclosure, as in figure 1 , 2 , 4 and 5 are shown in vertical section.

[0028] Such as figure 1 and 2 As shown, the compressor assembly 10 includes a compressor 12 and an external muffler assembly 14 . Compressor 12 may include a cylindrical hermetic housing 16 , a compression mechanism 18 , a main bearing housing 20 , a motor assembly 22 , a refrigerant discharge fitting 24 and a suction inlet fitting 26 . Sealed housing 16 may house compression mechanism 18 ...

Abstract

A compressor assembly may include a shell, a discharge fitting, a muffler, a compression mechanism, and a motor. The shell may have an opening therethrough with the discharge fitting generally extending therefrom. The muffler may be in communication with the discharge fitting and may be external to the shell. The muffler may have an inlet proximate the discharge fitting, an outlet distal from the discharge fitting, and a body portion extending therebetween. The muffler may include a valve assembly proximate the outlet. The compression mechanism may be contained within the shell and include a suction inlet and a discharge passageway. The discharge passageway may be connected to the opening in the shell for direct discharge of refrigerant from the compression mechanism to the discharge fitting. The motor may be contained within the shell and drivingly coupled to the compression mechanism.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 60 / 984,908, filed November 2, 2007. The entire disclosure of the above application is hereby incorporated by reference. technical field [0003] The present disclosure relates to a scroll compressor, and more particularly, to a scroll compressor having a muffler. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Refrigerant inline compressors for systems such as air conditioners, refrigerators or freezers may include external silencers to reduce discharge pressure pulses and / or noise. These compressors may also include means to prevent back flow during shutdown to prevent damage to the motor. When the compressor is off, the compression mechanism is at a lower pressure than the discharge fitting and external muffler. In the...
