A pressure pulse dampener for a compressor system is disclosed herein. The pulse dampener includes a housing having inlet passageway and an outlet passageway. A radially expanding annular passageway is formed downstream of the fluid inlet. A toroidal passageway is formed downstream of the annular passageway, the toroidal passageway being configured to direct fluid in a generally circumferential path around the central body. A connecting passageway is formed through the central body to provide fluid communication between the toroidal passageway and the fluid outlet.

Aerodynamic pressure pulsation dampener

A compressor system operable to shutdown in response to a shutdown signal. The compressor system includes a compression device operable between a first speed and a second speed to produce a flow of compressed fluid at a pressure. A blowdown valve is movable between a closed position and an open position in which at least a portion of the flow of compressed fluid passes through the blowdown valve to reduce the pressure of the flow of compressed fluid. A sensor is positioned to measure the pressure and a controller is operable to move the blowdown valve to the open position and set the speed of the compression device to a low set point speed in response to the shutdown signal.
