Filed:

Jun 5, 2007

Appl. No.:

11/810465

Inventors:

Jack S. Vilendre - West Linn OR, US
M. Kevin Hardwick - North Plains OR, US
Dwayne M. Abelein - Portland OR, US

International Classification:

F16K 31/02

US Classification:

25112909, 13724725

Abstract:

A self-contained trap primer valve assembly is housed in a cabinet and includes a conduit for connection to a building's water main to carry water under pressure, a valve is operatively mounted in the conduit and a solenoid is operable for selectively opening and closing the valve, wherein a low voltage battery and a timer mechanism connected to the battery and preset for selectively actuating the solenoid, opens and closes the valve for preselected durations.

Assignee:

JL INDUSTRIES, INC. - Portland OR

International Classification:

E03C 1/28

US Classification:

13724715, 13724725

Abstract:

International Classification:

E03C 1/296

US Classification:

13724725

Abstract:

A pressure activated trap primer valve for drain traps includes an expansion chamber with a piston between the compressible air and water. The piston prevents waterlogging of the expansion chamber to reduce maintenance of the trap primer valve. The trap primer valve also includes an inlet pipe coaxially configured in the expansion chamber. The inlet pipe is operably connected to a chamber below the expansion chamber which is closed at the bottom by a diaphragm. The diaphragm in a relaxed, undeflected position closes an outlet that drains to the trap. A chamber below the diaphragm is replenished by the expansion chamber. When pressure in the supply pipe and inlet pipe decreases, such as when a faucet is opened, the diaphragm deflects. Deflecting the diaphragm opens the outlet, allowing a limited amount of water to flow out of the chamber and into the trap. The intermittent water flow to the trap ensures a minimum volume for maintaining a gas tight seal in the trap. As trap primer valve pressures reach equilibrium, the diaphragm returns to an undeflected position, sealing the outlet again.
