US Patent:

7140386, Nov 28, 2006

Filed:

Jun 16, 2005

Appl. No.:

11/155693

Inventors:

Alan Avis - Placerville CA, US
Brian Rodman - Sacramento CA, US

International Classification:

F16K 17/30

US Classification:

137504, 137460, 1375133, 137517

Abstract:

A surge suppressor and safety shut-off valve is described which automatically shuts off fluid flow in response to a sufficient pressure differential across the valve. The shut-off valve comprises a valve body adapted for use within a fluid distribution system through which a predetermined flow of a fluid is nominally allowed to pass. A flow restricting means is disposed therein that reduces the maximum flow when triggered by a sufficient pressure differential between inlet and outlet. By way of example, the flow restricting means is preferably provided by a poppet which is slidably engaged within the valve chamber to restrict fluid flow therethrough. The poppet is preferably adapted with a very low volume bypass port through which opposing pressures at valve inlet and outlet may be equalized for automatically resetting of the valve after the surge has passed, or a rupture has been repaired.

Appl. No.:

12/343096

Inventors:

Brian Rodman - El Dorado Hills CA, US

International Classification:

F16B 37/08

US Classification:

411432

Abstract:

The invention provides a female nut comprising a) an inner cylindrical member having first and second open ends, a threaded inner bore, and a non-threaded outer surface, where the cylindrical member is comprised of first and second longitudinally divided members, whereby the first and second divided members together form the cylindrical member; and b) an outer sheath having first and second open ends, a non-threaded inner bore and an outer surface, where the outer sheath fits over the assembled cylindrical member with the inner bore of the outer sheath in close contact with the outer surface of the cylindrical member and respective first open ends adjacent.
