Abstract
A reciprocating compressor includes a piston slidably mounted within a compression chamber and defining a suction port for receiving a flow of gas. A flex mount is mechanically coupled to the piston and has an inner surface that defines a suction cavity. A suction muffler is positioned at least partially within the suction cavity and includes an inlet tube extending along the axial direction within the suction cavity and defining an inlet passageway configured to receive the flow of gas and a plurality of chamber plates that extend along the radial direction from an outer surface of the inlet tube, the plurality of chamber plates and the flex mount defining a plurality of resonance chambers to reduce compressor noise.
Claims20
A reciprocating compressor defining an axial direction and a radial direction, the reciprocating compressor comprising:
- a cylindrical casing defining a compression chamber;
- a piston positioned within the compression chamber and being movable along the axial direction, the piston defining a suction port for receiving a flow of gas;
- a flex mount mechanically coupled to the piston, the flex mount having an inner surface that defines a suction cavity;
- and
- a suction muffler positioned at least partially within the suction cavity of the flex mount, the suction muffler comprising:
- an inlet tube extending along the axial direction within the suction cavity and defining an inlet passageway configured to receive the flow of gas;
- and
- a plurality of chamber plates that extend along the radial direction from an outer surface of the inlet tube, the plurality of chamber plates and the flex mount defining a plurality of resonance chambers.
A suction muffler for a reciprocating compressor, the reciprocating compressor defining an axial direction and a radial direction, the reciprocating compressor comprising a piston positioned within a compression chamber, a flex mount mechanically coupled to a piston and having an inner surface that defines a suction cavity and a locking flange that extends from the inner surface of the flex mount toward the suction muffler along the radial direction, the suction muffler comprising:
- an inlet tube extending along the axial direction within the suction cavity and defining an inlet passageway configured to receive a flow of gas;
- a plurality of chamber plates that extend along the radial direction from an outer surface of the inlet tube, the plurality of chamber plates and the flex mount defining a plurality of resonance chambers;
- and
- a latching feature that engages the locking flange to secure the suction muffler within the suction cavity.
