Abstract (en)
[origin: WO2013029175A1] A variable gas pressure regulator comprises a throttling valve regulating the fluid flow between a high-pressure fluid inlet and a regulated space fluidly connected to a fluid outlet, a high-pressure solenoid commanded to control fluid flow between the fluid inlet and a control space and a low-pressure solenoid commanded to control fluid flow between the control space and the regulated space. The regulator achieves a variable pressure at the regulator outlet by commanding the two solenoids to control the pressure in the control space relative to the regulated space. The regulator further comprises a lock-off valve which is controlled by the action of the low-pressure solenoid and of the high- pressure solenoid based on the relative pressure difference between the control space and the regulated space. The lock-off valve seals the passage between the fluid inlet and the regulated space.
