ABSTRACT:
An electrically controlled faucet is disclosed which is operable by pushing a button or placing hands within the operating range of a sensor. The faucet is mounted to a sink deck or like surface using specially configured gasket means which insure against slippage of the faucet on the deck. The gasketing means provide special channels through which electrical operating wires can be securely passed from the faucet to operating means below the sink deck. These operating means include a solenoid valve that controls fluid flow through the faucet and a temperature control valve fluidly linked to the solenoid valve. Solenoid disabling pressure buildup in the line linking the temperature control valve and solenoid is bled through special bleed means in the temperature control valve inlets.
