Abstract
Compressors and methods for operating compressors are provided. In one example, a compressor is provided that comprises a ported shroud including a first port positioned upstream of a leading side of a rotor and a second port positioned downstream of the leading side of the rotor. The compressor also includes a muffler arranged in the ported shroud and comprising a plurality of projections, each of the plurality of projections radially extend from a base of the muffler and include an aperture extending through the base.
Claims20
A compressor, comprising:
- a ported shroud including a first port positioned upstream of a leading side of a rotor, a second port positioned downstream of the leading side of the rotor, and a ported shroud channel extending between the first port and the second port;
- and
- a muffler arranged in the ported shroud channel and comprising a plurality of projections, where each of the plurality of projections radially extends from a base of the muffler and includes an aperture extending through the base.
A method for operating a compressor in an engine, comprising:
- operating the compressor in a first airflow range where air is recirculated through a ported shroud channel from a second port to a first port and a muffler positioned in the ported shroud channel decreases compressor noise in a selected frequency range, where the first port is positioned upstream of a leading side of a rotor and the second port is positioned downstream of the leading side of the rotor;
- and
- operating the compressor in a second airflow range where air flows through the ported shroud channel from the first port to the second port;
- where the muffler includes a plurality of projections and where each of the plurality of projections extends from a base of the muffler;
- and
- where a support rib radially extends across the ported shroud channel and is arranged between the first port and the second port.
A compressor, comprising:
- a ported shroud including a first port positioned upstream of a leading side of a rotor, a second port positioned downstream of the leading side of the rotor, and a ported shroud channel extending between the first port and the second port;
- and
- a muffler arranged in the ported shroud channel and comprising a plurality of projections;
- where each of the plurality of projections radially extends from a base of the muffler and includes an aperture extending through the base;
- where each of the plurality of projections includes a curved inner surface radially extending towards a rotational axis of the compressor;
- and
- where the ported shroud includes a support rib that radially extends across a ported shroud channel and is arranged between the first port and the second port.
