Valve system especially for a sanitary fixture
First Claim
1. A valve system for a water outlet comprising:
- a lever-operated valve having a housing provided with a central axis and formed with said water outlet, at least one water inlet communicating with said housing, a valve member in said housing between said inlet and said outlet, and a control lever swingable on said housing along a path about a pivot axis transverse to said central axis;
a detent member in said housing formed with a detent opening along an arcuate path of said lever;
a spring-loaded detent body bearing on said member and engaging in said opening upon displacement of said lever about said pivot axis to a predetermined angular position in opening of said valve; and
electric circuitry responsive to angular displacement of said lever and including;
at least one further valve in series with said lever-operated valve for controlling outflow from said outlet, an electrical control for said further valve, a contactless detector operatively connected to said electrical control for maintaining said further valve open for a duration determined by activation of said detector, and a switch in said housing connected with said control for rendering said detector effective in said predetermined angular position of said lever and rendering said detector ineffective in angular positions of said lever other than said predetermined angular position for control of said outflow by said lever-operated valve without limitation by said further valve.

Abstract
A manually-operated valve is provided in series with an electromagnetically-operated valve and the manually-operated valve is provided with a proximity detector connected to the electronic controller whereby a switch in the manually-operated valve, in one position of the single control lever therefor, corresponding to about 50% of maximum supply rate, is operated to activate the proximity sensor and enable the water flow to be controlled by an object within its detection range. Removal of the object, e.g. the hand of the user from the range, will shut off the water through the manually-operated valve. Outside the position of the lever at which the switch is operated, the proximity detector is ineffective and control is effected exclusively by swinging the lever.
