Patent number: 11326704Abstract: A pressure relief apparatus for venting a tank comprising an inlet port, an outlet port, a closure member retained, relative to the inlet and outlet ports, for preventing, or substantially preventing, fluid communication between the inlet port and the outlet port, a trigger mechanism including a temperature response portion, and a compartment for receiving pressurized fluid from the outlet port and communicating the received pressurized fluid to the trigger mechanism. The trigger mechanism and the closure member are cooperatively configured to release the closure member and establish fluid communication between the inlet port and the outlet port, thereby venting the tank, upon detection of a temperature at or above a predetermined temperature threshold or upon pressurization of the compartment at or above a predetermined pressure threshold.Type: GrantFiled: June 13, 2018Date of Patent: May 10, 2022Assignee: Emcara Gas Development Inc.Inventors: Erick Girouard, Amir Ahmadzadegan

Patent number: 6557821Abstract: 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.Type: GrantFiled: June 22, 2001Date of Patent: May 6, 2003Assignee: Teleflex GFI Control Systems L.P.Inventors: Erick Girouard, Mark W.
