Abstract
A valve includes a valve body, an inlet in the valve body in fluid communication with the gas and an outlet in the valve body, and a rupture disc in fluid communication with and between the inlet and the outlet that prevents fluid communication between the inlet and the outlet. The valve also includes a piston that is urged by a gas from the gas source to rupture the rupture disc to allow fluid communication between the gas source and the outlet.
Claims18
An inflation system, comprising:
- a gas source;
- a valve including:
- a valve body;
- an inlet in the valve body in fluid communication with the gas source;
- an outlet in the valve body;
- a rupture disc in fluid communication with and between the inlet and the outlet, wherein the rupture disc prevents fluid communication between the inlet and the outlet;
- and
- a piston, wherein the piston is urged by a gas from the gas source to initially rupture the rupture disc to allow initial and subsequent fluid communication between the gas source and the outlet.
5 more elements
A method to inflate an inflatable device, the method comprising:
- providing a gas source in fluid communication with an inlet;
- preventing fluid communication between the inlet and an outlet via a rupture disc;
- urging a piston into the rupture disc by pressurizing the piston using gas from the gas source;
- initially rupturing the rupture disc via the piston being pressurized by the gas from the gas source;
- and
- providing initial and subsequent fluid communication between the gas source and the outlet via the rupture disc.
3 more elements
An inflatable system, comprising:
- an inflatable device having a device inlet, and
- an inflation system, including:
- a gas source;
- a valve including:
- a valve body;
- an inlet in the valve body in fluid communication with the pneumatic source;
- an outlet in the valve body;
