Abstract
A gas compressor assembly configured to pressurize an airflow received from the ambient for delivery to an internal combustion engine having a cylinder includes a compressor housing. A compressor wheel is disposed inside the compressor housing and configured to pressurize the airflow. A compressor bypass is configured to direct the pressurized airflow away from the cylinder. A pressure relief valve is configured to selectively open and close the compressor bypass to thereby limit pressure of the pressurized airflow and minimize surge of the compressor wheel. A baffle arranged inside the compressor bypass is configured to dissipate energy of a sound wave generated by the pressurized airflow upon an initial opening of the pressure relief valve. An internal combustion engine employing such a turbocharger is also disclosed.
