    Abstract: 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.

    CPC classification number: B64D1/22

    Abstract: A cable cutter assembly for an aircraft hoist is disclosed, and includes an actuator assembly (e.g., at least one pressurized fluid cavity, a first outlet port, and a solenoid that includes a coil and an armature). The armature is movable between closed and open positions relative to the first outlet port (e.g., via an actuation force), with the armature engaging the first outlet port for the closed position (e.g., a valve seal incorporated by the armature) and being spaced from the first outlet port for the open position. A cutter body includes a cutter body cavity that is fluidly connected with the first outlet port. A cutter is movably disposed within the cutter body cavity. Disposing the armature in the open position (e.g., via energizing the coil) fluidly connects the pressurized fluid cavity with the cutter body cavity to move the cutter in a cable cutting direction.

    Abstract: An actuator is disclosed herein. The actuator includes a drive body including a bottom surface, the bottom surface having a first side and an opposing second side, a magneto strictive material disposed within the drive body and contacting the first side of the bottom surface of the drive body, a solenoid disposed within the drive body and surrounding the magneto strictive material, a drive rod extending through the magneto strictive material and through the bottom surface of the drive body, and a spring disposed adjacent the second side of the bottom surface of the drive body, wherein the drive rod extends through the spring.

    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.
