  • Publication number: 20230265932
    Abstract: An improved deflator valve for reducing deflation time. The deflator valve has a main body with one or more ports, one or more vents, or port or vent slots for introducing air into or relieving pressure from within the main body in a vortex, circular flow. The deflator valve also includes a piston having an O-ring disposed around an outer circumference of the piston. The O-ring of the piston and the ports and vents are effective for reducing noise and deflation time and improving accuracy and ease of adjusting a pressure setting. The deflator valve can further include a dual or variable rate spring that can achieve an extensive destination pressure range. The deflator valve can also include a threadless lead in, fewer valve stem threads, or a lock chuck for enhanced valve stem attachment methods.

  • Patent number: 11376895
    Abstract: A dual, internal, pneumatic, boltless beadlock assembly for effectively securing a tire to a rim is disclosed. A pneumatic beadlock assembly is disposed inside a tire and mounted on a rim. A pneumatic beadlock assembly exerts a force on the two circumferential inner beads of a tire such that the tire stays in secure contact with the rim, even when the inflation pressure of the tire is not sufficient to lock the tire to the rim.

  • Patent number: 9802449
    Abstract: The present invention overcomes the shortcomings of the current trial and error method in deflating tires. The controlled tire deflation valve system allows for tires to automatically and accurately deflate to the desired pressure. The present invention comprises a shaft, a spring and a piston wherein the shaft runs through the spring until the spring rests on the shaft spring seat. The shaft spring seat is effective in restricting the movement of the spring.
