19. An electronic faucet comprising
a housing; -
at least one fluid inlet line flowing extending into the housing; a fluid outlet from the housing; a solenoid valve in the housing controlling the fluid flow between said at least one inlet line and the outlet, and a controller constructed and arranged to control opening and closing of the valve, said controller including a power supply, and a control circuit for controlling the delivery from the power supply means to the valve, said control circuit comprising a touch pad accessible from outside the housing, a detector connected to the touch pad for producing a touch signal when the touch pad is touched, and responsive to the touch signal for delivering power to the valve so as to open the valve for a selected time duration. - View Dependent Claims (20)

22. A valve device, comprising:
-
a fluid input port and a fluid output port; a valve body defining a valve cavity and including a valve closure surface; and a fram assembly providing two pressure zones and being movable within said valve cavity with respect a guiding member;
said fram assembly being constructed to move to an open position enabling fluid flow from said fluid input port to said fluid output port upon reduction of pressure in a first of said pressure zones; and
being constructed to move to a closed position, upon increase of pressure in said first pressure zone, creating a seal at said valve closure surface. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
