Abstract
A plastic valve cartridge for a plumbing fixture can be installed in and removed from a valve casting without tools. One end of a valve cage has detent means that snaps into a cup of the casting. The cage extends across a cavity in the casting so that its other end fits a cylindrical inlet opening. Valve means carried by the cage include a closure having a stem comprising a pair of leaf spring arms releasably snap-fitted to a non-circular hole in a knob or handle. The cage is locked in position by a sleeve that interferes with the detent means of the cage. Key means allow the sleeve to be removed only when the valve is partly open, thus signalling by spout flow the desirability of shutting off the water supply to the fixture before the cartridge is removed.
