  • Publication number: 20230375103
    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.

  • Publication number: 20230376052
    Abstract: A speed regulation mechanism suitable for use with a bi-directional actuator is disclosed. The mechanism includes an actuation element and a regulator. The actuation element is configured to reversibly move between a first position and a second position. The regulator is configured to rotate around a regulator axis (A), and the actuation element is coupled to the regulator. Movement of the actuation element in a first direction towards the second position causes rotation of the regulator around the regulator axis (A) in a first rotational direction, and movement of the actuation element in a second direction towards the first position causes rotation of the regulator around the regulator axis (A) in a second rotational direction.
