Abstract
A valve structure including a valve body defining a valve chamber with a tapered bearing surface and a tapered valve member journaled in the tapered bearing surface. A spring-biased plunger mechanism constantly urges the valve member into slidable sealing engagement with the tapered bearing surface. A passage communicates between the valve chamber and the exterior of the valve body via the spring-biased plunger mechanism and is connected in fluid flow communication with a source of suitable fluid, whereby such fluid passes from the source into the valve chamber via the spring-biased plunger mechanism.
