Abstract
A compressor apparatus (20) has a housing (22) having first (53) and second (58) ports along a flowpath. One or more working elements (26; 28) cooperate with the housing (22) to define a compression path between suction (60) and discharge (62) locations along the flowpath. A check valve (70; 170; 270) has a valve element (72; 172; 272) mounted for movement between a first condition permitting downstream flow along the flowpath and a second condition blocking a reverse flow. The valve element includes a resonator (112; 174; 274).
Claims18
A compressor apparatus (20) comprising:
- a housing (22) having first (53) and second (58) ports along a flow path;
- one or more working elements (26;
- 28) cooperating with the housing (22) to define a compression path between suction (60) and discharge (62) locations along the flow path;
- and
- a check valve (70;
- 170;
- 270) having a valve element (72;
- 172;
- 272) mounted for movement between a first condition permitting downstream flow along the flow path and a second condition blocking a reverse flow,
- wherein, the valve element includes a resonator (112;
- 174;
- 274).
A method for remanufacturing a compressor or reengineering a configuration of the compressor comprising:
- providing an initial such compressor or configuration having:
- a housing having a flow path between first and second ports;
- a one or more working elements cooperating with the housing to define a compression path between suction and discharge locations along the flowpath;
- and
- a check valve along the flow path and having a valve element mounted for movement between a first condition permitting downstream flow along the flowpath and a second condition blocking a reverse flow;
- and
- selecting at least one geometric parameter of a resonator compartment in the valve element to provide a desired control of a pressure pulsation parameter.
