Abstract

The electrical water faucet is designed to control the flow of water from an outlet, through the use of switches controlling electrical solenoids. This unit can be installed in remote areas to confine static service line water pressures. This electrical water faucet has a manual control to operate it if electrical power should fail.

Claims

1. An electric solenoid controlled faucet comprising:

a. a faucet housing substantially encasing a cylindrical chamber, b. a piston secured to a shaft movably mounted in the cylindrical chamber in said housing, c. said piston dividing said cylindrical chamber into an upper secondary chamber and a lower primary chamber, d. a closing solenoid operably mounted on said housing, e. a closing solenoid passage leading from said lower primary chamber to, f. a chamber of said closing solenoid, g. a secondary chamber passage extending through the faucet housing interconnecting said chamber of said closing solenoid and said secondary chamber, h. said secondary chamber passage receiving fluid pressure from said primary chamber through said chamber of said closing solenoid to said secondary chamber when said closing solenoid is open applying pressure to said piston closing said faucet, i. an opening solenoid operably mounted on said housing, j. a passage projEcting through said faucet housing interconnecting said secondary chamber and, k. the chamber of said opening solenoid, l. a spill passage interconnecting said chamber of said opening solenoid and, m. the outlet branch line from said valve housing, n. said spill passage and said passage from said secondary chamber to said opening solenoid including means adapted to release fluid from said secondary chamber through said chamber of said opening solenoid when said means is open permitting said faucet to open.

2. The invention of claim 1 further comprising:

a. an inlet port leading from an external source of fluid pressure directly communicating with, b. said lower primary chamber, c. any fluid pressure received through said inlet port being directly applied to the piston surface contacting said primary chamber thereby urging said faucet to an open position.

3. The invention of claim 2 further comprising:

a. a valve seat mounted in said housing adjacent said inlet port, b. a valve shut-off seal mounted on said shaft secured to said piston, said valve shut-off seal constructed and arranged to securely contact said valve seat closing said faucet, said faucet remaining open when said seat is not so contacted, and c. a diametrical restrictor projecting from said valve shut-off seal, said diametrical restrictor constructed in a configuration adapted to project into said valve seat as said valve shut-off seal moves toward said valve seat.

4. The invention of claim 3 further comprising:

a. a spring connected to said shaft of said piston, said spring being tensioned in such a manner as to normally urge said valve shut-off seal and said diametrical restrictor in the direction of said valve seat.

5. The invention of claim 1 further comprising:

a. a switch positioned remote from said closing solenoid connected to said solenoid by a wiring harness means, b. said switch being connected to an external source of electrical energy adapted to control said solenoid from a position remote to said faucet.

6. The invention of claim 1 further comprising:

a. a spring operably connected to said shaft of said piston biasing said piston toward a faucet closed position.

7. The invention of claim 1 further comprising:

a. a solenoid plunger seat mounted in said closing solenoid chamber intermediate said closing solenoid passage and said pressure passage to said secondary chamber, b. a solenoid plunger seat mounted in said opening solenoid chamber intermediate said passage to said secondary chamber and said opening solenoid and said spill passage, and c. the contacting or lack of contacting of said plunger seats by said solenoids controlling the flow of pressure to and from said secondary chamber.
