Abstract
There is disclosed herein a refrigeration compressor having an induction system which includes a conduit for directing suction gas to the compressor and an associated muffler designed to attenuate noise generated by the suction process while still allowing relatively unrestricted flow through the conduit. In one form the conduit and associated suction muffler are integrally formed from a suitable plastic composition as a two piece assembly with the associated muffler being in the form of an elongated chamber overlying an opening in the conduit and arranged in longitudinally parallel relationship thereto.
Claims21
A hermetic compressor comprising:
- an outer shell;
- compressor means mounted within said shell;
- motor means secured to said compressor means;
- and
- elongated suction conduit means having one end secured to said compressor means, said suction conduit means defining a relatively unrestricted suction gas flow path therethrough for conducting suction gas from the interior of said shell to said compressor means, said suction conduit means including an elongated substantially closed noise attenuating chamber having a longitudinal axis disposed in substantially parallel offset relationship to the axis of said suction gas conduit, said chamber being positioned intermediate the ends of said conduit and an opening in said conduit for placing said chamber in communication with said suction gas flow path.
In a hermetic compressor including an outer shell having a compressor mounted therein, motor means drivingly connected to said compressor, a motor shroud enclosing one end of said motor means, a suction gas conduit assembly comprising:
- a suction gas conduit having one end secured within an opening provided in said shroud and the other end disposed within an opening provided in said compressor, said suction gas conduit defining a substantially unrestricted flow path for conducting suction gas from said shroud to said compressor;
- an opening provided in a side wall of said suction gas conduit intermediate the ends thereof;
- and
- noise attenuating means overlying said opening, said noise attenuating means including an elongated closed chamber having a longitudinal axis disposed in substantially parallel offset relationship to the axis of said suction gas conduit, said chamber having an axial length greater than the width thereof and being positioned with said opening being immediately adjacent one end thereof.
In a hermetic compressor including an outer shell having a compressor mounted therein, motor means drivingly connected to said compressor, a motor shroud enclosing one end of said motor means, a suction gas conduit assembly comprising:
- a suction gas conduit having one end secured within an opening provided in said shroud and the other end disposed within an opening provided in said compressor, said suction gas conduit defining a substantially unrestricted flow path for conducting suction gas from said shroud to said compressor;
- an opening provided in a side wall of said suction gas conduit intermediate the ends thereof;
- and
- noise attenuating means overlying said opening, said noise attenuating means including an elongated closed chamber having a longitudinal axis disposed in substantially parallel offset relationship to the axis of said suction gas conduit, said chamber having an axial length greater than the width thereof and being positioned with said opening being approximately midway between opposite ends thereof.
