Abstract: An inflation system for an evacuation system may comprise an inflator and a controller operationally coupled to the inflator. The inflator may include a solid gas generating material and an igniter configured to ignite in response to receiving an ignite signal. The solid gas generating material may be configured to generate a gas in response to an ignition of the igniter. The controller may be configured to send the ignite signal to the inflator.

Abstract: A valve arrangement for inflating an inflatable device includes a valve body comprising an inlet, an outlet, a main fluid channel, a first ball detent, and a second ball detent. A lifter and a sleeve are located in the main fluid channel. A locking ball is disposed at least partially within a locking ball aperture disposed in the sleeve. A piston is coupled to the lifter and fluidly coupled to a command pressure cavity of the valve body. A spring biases the lifter toward a ball locking position whereby the lifter urges the locking ball at least partially into the first ball detent. A valve operation initiator controls a flow of pressurized gas into the command pressure cavity to urge the lifter to a ball releasing position to free the sleeve, as to the locking ball, to translate to an open position to fluidly couple the inlet with the outlet.
