ABSTRACT:
A hydrant includes one or more novel and improved features, namely: (1) a nozzle assembly comprising a nozzle and a retainer ring mounted from within the upper standpipe section of the hydrant; (2) an operating assembly defining an excess reservoir volume to receive valve stem lubricating fluid to prevent blocking movement of the valve stem; (3) a coupling assembly including a collar, a retainer ring for engaging one end of the collar against one standpipe section, and a retainer bar inserted through the collar and bent around an adjoining standpipe section; (4) a coupling assembly including a floating seal band carrying two seals, one of which seals against one standpipe section and the other of which seals against an adjoining standpipe section; (5) an otherwise conventional valve body but for a double-D valve body cavity in which a complemental boss of a valve member retainer disk is nested to prevent rotation therebetween, and also including a flat sealing gasket disposed between the valve stem and an annular surface of an upper cavity of the valve body.
