摘要： 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.

摘要： An inflation valve arrangement includes an actuation cavity housing connected to a pneumatic valve, the actuation cavity housing comprising an actuation cavity and a piston rod extending from the actuation cavity at least partially into a main fluid channel of the pneumatic valve in an initially extended position for securing the pneumatic valve in a closed position. The arrangement further comprises a solenoid actuated pressure cartridge connected to the actuation cavity housing. The solenoid actuated pressure cartridge comprises a self-contained source of actuation gas. In response to the solenoid actuated pressure cartridge being energized, the solenoid operated pressure cartridge is configured to release the actuation gas from the pressure cavity into the actuation cavity, thereby retracting the piston rod into the actuation cavity, and opening the pneumatic valve body to release a source of inflation gas to an inflation device.

摘要： 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.
