Patent ID: 7607453

Claim:
A freezeless hydrant having an inlet and an outlet, said hydrant including: an elongated pipe connecting a valve to an operator, said operator including an operator end, said operator end including threads; a stem having a length and having a first end engaged with said threads and a second end carrying a stopper portion of said valve, a portion of said stopper engaging projections on an inner portion of said pipe such that said stem and stopper are held against rotational movement by said projections as a compressive seal face on said stopper engages a surface of a reduced diameter of said pipe, rotational movement of said operator results in longitudinal movement of the stem and in closing of said valve by moving said stopper portion and moving said compressive seal face into compressive sealing engagement with said surface of a reduced diameter portion of said pipe, wherein said stopper includes a frictional seal face, and wherein upon closing of said valve, said frictional seal face forms a movable frictional seal with said reduced diameter section and wherein said frictional seal moves longitudinally while maintaining a seal prior to said compressive seal face engaging said reduced diameter portion, wherein said operator includes holes, said holes allowing water to drain from said hydrant through said operator when said frictional and compressive seal faces engage said reduced diameter portion shutting off flow from said inlet and wherein the first end of said stem includes a seal sealingly separating said holes from said valve when water is flowing through said hydrant and connecting said holes to said valve as said frictional seal face engages said reduced diameter portion.
