Abstract
A suction fitting for a compressor can include screens, filters, and direction control louvers to both filter out particulates and direct higher mass liquid refrigerant downward away from the inlet to the compression chamber. Alternatively, a mesh filter can be place over the opening(s) to the suction plenum to prevent debris and contaminants from entering the suction plenum.
Claims4
A compressor comprising:
- a shell having an enclosed space;
- a compression mechanism positioned within the enclosed space of the shell;
- a motor positioned within the enclosed space of the shell and connected to the compression mechanism by a shaft to power the compression mechanism;
- a motor cap positioned on the motor opposite the compression mechanism, the motor cap comprising a top surface and a sidewall extending from the top surface toward the motor, the top surface and sidewall defining a plenum between the motor and the motor cap to store refrigerant;
- the motor cap comprising at least one opening to provide passage of refrigerant between the enclosed space and the plenum;
- and
- a filter mechanism positioned over the at least one opening.
