摘要
A two-stage, bi-directional valve is provided for controlling gas flow into and out of a storage volume. The solenoid is provided to actuate a first stage piston to seal communication with a pressure source. In doing so, the sources imparted by the solenoid overcome biasing forces applied by a resilient spring on the first stage piston. Simultaneously, actuation of the first stage piston opens the bleed passage to permit the depressurization of space behind the second stage valve. Upon sufficient depressurization, the second stage valve is unseated from the main orifice by fluid pressure forces, thereby creating the flow path for escape of the gaseous fluid through the main orifice.
