Valves Controlling Flow

Abstract

Valves controlling flow of gas or liquid, where compressible material is trapped within a rigid housing to provide a leak-proof seal surrounding an longitudinally movable rigid shaft. Where the shaft has a hollow channel and perpendicular ports to the outer surface, it allows for on and off control and is called a hollow shaft valve. If the shaft has diametric reductions on its outer surface, the valve allows for variable control. Creating a series of hollow shaft valves and variable shaft valves on a single shaft allows multiple functions through a single seal to create a serial shaft valve. The technology also allows for the precise and indexed variable control of fluid flow through a variable shaft valve by having a bayonet style system to precisely actuate orifice size rather than a rotary handle. This arrangement has application in a wide variety of situations including chlorination valves. In the case of automobiles, the valve used to vent fuel in the case of an accident can be triggered by mechanical means, such as an airbag deployment sensor system.
