Abstract
A fluid purging system has a spring-energized relief valve having an inlet port that is coupled to a fluid chamber to receive incoming fluid, and an outlet port through which incoming fluid is relieved. The outlet port is fluidly coupled to a pressurized chamber. The fluid purging system also includes an electro-mechanical pressure switch, and an electrically operated solenoid valve which functions as a pressure exhaust valve. The pressure switch and the solenoid valve are in fluid communication with the pressurized chamber.
