US Patent:

43196047, Mar 16, 1982

Filed:

Feb 19, 1980

Appl. No.:

6/122136

Inventors:

Robert E. Bird - Eureka MO

Assignee:

Modern Engineering Company, Inc. - St. Louis MO

International Classification:

F16K 3112

US Classification:

137498

Abstract:

In a safety shut-off valve, a housing includes a valve member therein, having a first valve seat, and against which a valve normally rests during closure, with a spring normally biasing said valve off of said first valve seat, and with the force of the pressurized fluid passing through the valve causing said valve to act against the force of a regulator and a second spring to become unseated for allowing gas flow, and reseated once again against a second valve seat when excessive pressure is encountered and which curtails the further flow of fluid through the valve housing, and thereby shutting off the fluid from its source.

US Classification:

137613

Abstract:

In a single stage regulator as used in conjunction with a high pressure vessel, a surge reducing valve is positioned within the outlet from the regulator and just at its low pressure side of the regulator in order to reduce any surge or jump in the gas flow during sustained gas consumption or when it is shut off.
