Abstract: Solenoid-operated pressure-regulator modules, aircraft inflatable slide assemblies, and methods for assembling solenoid-operated pressure-regulator modules are described. The solenoid-operated pressure-regulator modules include a primary inflation valve, a secondary inflation valve, a secondary valve actuator, a solenoid, an inflatable slide, and a gas source. The solenoid-operated pressure-regulator modules are configured to selectively enable a fluid connection between a gas source and an inflatable slide to enable inflation of the inflatable slide. The primary inflation valve includes a main cavity, a command cavity, an inlet through which a gas enters the main cavity, an outlet, a poppet that controls a gas flow from the inlet to the outlet, and a valve divider separating the main cavity from the command cavity. The secondary inflation valve is fluidly coupled to the outlet of the primary inflation valve. The primary and secondary inflation valves are configured to be simultaneously operated by operation of the solenoid.

Abstract: An inflation valve is provided and includes a valve defining main and command cavities and including first and second valve portions and a valve seat defining an outlet, a poppet disposed in the main cavity and including first and second rods to engage with the first valve portion and to extend through the valve seat and the second valve portion, respectively, and a piston disposed in the command cavity and a solenoid valve. The solenoid valve normally prevents main cavity-command cavity fluid flow to engage the poppet with the valve seat by fluid pressure acting on the poppet in the main cavity and permits the main cavity-command cavity fluid flow when energized to disengage the poppet from the valve seat by balanced fluid pressure acting on the poppet in the main cavity and on the piston in the command cavity to permit main cavity-outlet fluid flow.
