Definitions

  • the present disclosure relates generally to a pneumatic valve system such as for use with tube and tubeless bicycle tires and methods of making and using the same. More particularly, the present disclosure relates to improved valve systems as an alternative to Schrader, Presta, and Dunlop valves, and other pneumatic valves.
  • Pneumatic valve systems for connecting a pressurized air source e.g., a pressurized tank or an air pump
  • a pressurized air source e.g., a pressurized tank or an air pump
  • Conventional devices heretofore devised and utilized are widely used, and yet continue to have design drawbacks. These devices are awkward to attach and keep attached while filling a tube or tire, and often do not provide a reliable seal on the valve stem of the tire, tube, or other structure, leading to leaks.
  • a poor coupling between conventional pneumatic valves and air pressure gauges may lead to inaccurate pressure readings and improperly inflated tires, which can reduce gas mileage (or slow a bicycle) and cause uneven wear on the tire, reducing the life of the tire and potentially voiding manufacturer warrantees.
  • conventional devices fulfill their respective, particular objectives and requirements (i.e., increasing air pressure in a tube or tire), they also have functional drawbacks that can be frustrating. For instance, often times the use of a valve coupling requires a person to be awkwardly and uncomfortably positioned for a length of time while filling a tube or tire. In such situations, reliability in the connection of the valve is highly desirable to avoid as much physical discomfort and wasted time as possible.
  • the Schrader valve has significant connection problems due to the manner in which the pump-head is secured to the valve stem. Because the seal between the pump-head and the valve is made on the outside of the valve stem, the internal surface area shared between the distal end of the valve stem and the pump-head valve cavity is relatively large. As a result, the internal pressure of the tire or other vessel to which the valve is attached exerts significant force upon internal pump-head surface that can result in the pump-head being blown off of the valve without a mechanism to hold it in place. To properly secure the pump-head to the valve, a locking lever is included in the Schrader pump-head design.
  • the grasping mouth piece of the Schrader pump-head exerts significant force to sufficiently compress the rubber in order to keep the pump-head from “popping” off due to the high instantaneous output pressures from the pump in combination with the building of internal pressure in the tire or other vessel.
  • virtually all Schrader valve pump-heads suffer from the same problem - they are difficult and awkward to lock, requiring two hands and considerable finger strength to mate and lock the pump-head.
  • the Presta valve has several disadvantages, and is notoriously difficult to use. It has the same issues as a Schrader valve, namely, that the pump-head experiences forces sufficient to blow it off the valve stem without a locking mechanism. The locking lever and chuck are difficult and awkward to handle.
  • the Presta valve has additional difficulties and drawbacks, including the additional inconvenience of having to unscrew the captive nut that forms part of the valve stem structure, the requirement of a specialized pump that fits the specialized Presta design, the delicate and damage-prone design of the Presta valve stem, and the common problem of the threaded core of the Presta valve stem unthreading from the stem housing when engaged with a pump-head.
  • a pneumatic valve is provided.
  • the valve includes a body having a bore on one end and a groove communicating with the bore, the body further having a passageway in fluid communication with the bore, the body further having a circumferential groove on an outer diameter.
  • a valve seat is disposed in the groove.
  • a sealing plug is disposed within the passageway.
  • a biasing member is provided that engages the passageway and biasing the sealing plug against the valve seat.
  • further embodiments of the pneumatic valve may include an insert coupled to the bore, the insert having a wall with an end that is substantially parallel with a side of the groove.

  • further embodiments of the pneumatic valve may include a coupler configured to couple with a valve stem, wherein the body includes a flange on an outer diameter, the flange being disposed between a shoulder of the coupler and an end of the valve stem when installed on the valve stem.
