Abstract

A sliding valve assembly includes a valve body having a fluid conducting port adjacent to a fluid impervious surface. The actuator allows fluid to travel through the valve assembly and into a fluid blocking position where the fluid impervious surface obstructs the fluid from traveling through the valve assembly. First and second sealing assemblies include a primary seal ring, a secondary seal ring around the primary seal ring, and a spring forcing the primary seal ring against a sealing surface. As pressure in the system increases, this pressure is delivered to the sealing assemblies to force them against the sealing surfaces to enhance the sealing relationship. Cams and cam followers affixed to the valve body overcome the frictional forces of the sealing system and the valve body and valve housing to increase the efficiency of the valve assembly and the system in which the valve assembly is used.
