Abstract

A flow-control valve has a housing, a valve cartridge in the housing connectable between sources of hot and cold water and an output and including a valve for varying a volume/rate parameter and a temperature parameter of flow from the sources to the output, and a lever pivoted on the cartridge about two transverse axes, connected to the valve means, and movable by pivoting about one of the axes along a path in one direction relative to the housing to vary one of the parameters and movable by pivoting about the other of the axes in another direction relative to the housing to vary the other parameter. A stop is provided on the housing outside the valve cartridge along the path engageable with the lever. A biasing or spring unit urges the stop transversely into the path of the lever and thereby inhibits movement of the lever along the path past the stop.
