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.
