Abstract of the Disclosure An energy saving push button faucet for delivering a predetermined volume of water in a set period of time includes a control valve with a movable plunger having a front face and a rear face, the front face of the plunger is normally retained upon a valve seat shutting off flow through the valve in the faucet by supply line pressure on the rear face. The valve also includes a pilot valve which can be actuated by a push button to relieve the pressure on the rear face and permit supply line pressure on the front face to move the plunger off the seat and open the valve. The nose of the plunger is provided with an internal passage containing a flow control mechanism which reduces the effective diameter of the passage to control the volume of water delivered by the faucet. The valve also includes an adjustable timing mechanism which determines the timing cycle or length of time the valve remains open.
