Filed:

Oct 22, 1979

Appl. No.:

6/086764

Inventors:

Thomas G. Barnum - Fox Point WI

Assignee:

Bradley Corporation - Menomonee Falls WI

International Classification:

F16K 31122

US Classification:

251 44

Abstract:

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. When the valve is open, water flowing through the valve from the supply line to the faucet outlet passes through the flow control mechanism in the nose of the plunger.

Abstract:

An improved flood level sensor has an upstanding, vented tube extending above and outside a receptacle while maintaining fluid communication with an enclosed rim of the receptacle. A partial vacuum is communicated to an orifice which is located within the tube at a height related to a limit on the level of fluid in the receptacle. The level of fluid in the tube depends upon the fluid pressure in the enclosed rim and therefore upon the fluid level in the receptacle. When the fluid level in the receptacle is below flood level, the orifice is able to relieve any partial vacuum communicated to it. However, when the level of fluid in the receptacle rises to the flood level, the fluid level in the tube rises to partially seal the orifice and prevent relief of the partial vacuum which then actuates a valve lockout device.
