Abstract: A regulator valve assembly may comprise: a housing defining an actuator cavity and a piston head cavity; a piston rod comprising a piston head disposed within the piston head cavity and a rod end disposed within the actuator cavity; and a disc retainer within the housing. The actuator cavity can have a top region of the actuator cavity and a bottom region of the actuator cavity. The piston head cavity can comprise a regulator inlet and an inlet port. The disc retainer can be coupled to a proximate seating surface of the inlet port, wherein a first face of a membrane disc is coupled to a lateral seating surface of the inlet port disposed between the piston head cavity and the disc retainer. Also disclosed are methods of using and manufacturing regulator valve assemblies.

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.
