Fluid pressure releasing system and method
A system and method for enabling rapid and controlled releasing of fluid pressure, as for deflating a tire. The system, in an embodiment thereof, enables rapid and controlled deflation of a tire to enable a vehicle to navigate in rough or unstable terrain.
1. A system for enabling deflation of a tire, adapted for use in a tire air valve which includes a valve stem which is extendable through a wheel rim, wherein the stem includes an extendable portion which is adapted to be extendable outside and adjacent to the wheel rim, wherein the tire deflation system comprises:
at least one opening, formed in the extendable portion of the valve stem; and
an external element, adapted to be extendable about the opening in the extendable portion of the valve stem, and adapted to be secured in position relative to the extendable portion of the valve stem so as to cover the opening, and to be movable so as to uncover the opening for enabling deflation of the tire, wherein the valve stem further includes an outer portion, which extends from the extendable portion, and which is threaded on the outside thereof and adapted to receive a cap threadably securable thereto, and which includes an air valve extending therein.
