Abstract:
1. A device for handling pressurized gas, said device comprising: a housing having an inlet, an outlet, and a flow path from said inlet to said outlet; first and second valves located within said housing; an actuator arranged to initially open said first valve for flowing gas in a first direction at a first flow rate through a pressurization orifice, and to subsequently open said second valve for flowing gas in an axial direction at a second flow rate through said device, said second flow rate being greater than said first flow rate, said axial direction being the same as said first direction, said actuator comprising a piston unit slidably located within said actuator, said piston unit further comprising an upper seat of said first valve, said upper seat being in communication with an upper portion of said pressurization orifice; and a lower cup-shaped valve element located within said housing, said lower cup-shaped valve element having an annular recessed area for receiving a lower seat of said second valve, said lower seat being in communication with a lower portion of said pressurization orifice.
