US Patent:

20080000531, Jan 3, 2008

Filed:

Jun 28, 2006

Appl. No.:

11/477959

Inventors:

Scott Robb - Chandler AZ, US
Don J. Atkins - Chandler AZ, US
Paul W. Banta - Phoenix AZ, US

International Classification:

F16K 31/36

US Classification:

137488

Abstract:

An apparatus is provided for a regulator valve comprising a duct, a valve element, a regulator unit, and a fluid pressure sensor. The duct has an inner surface that defines a flow passage. The valve element is movably disposed within the duct flow passage. The regulator unit is coupled to the valve element, and is further coupled to receive fluid at a feedback pressure magnitude. The regulator unit is configured to controllably position the valve element based at least in part on the feedback pressure magnitude, to thereby regulate fluid pressure downstream of the valve element to a regulated pressure magnitude that results in a static pressure magnitude at least proximate the duct inner surface. The fluid pressure sensor is disposed downstream of the valve element, and is configured to supply the fluid at the feedback pressure magnitude, with the feedback pressure magnitude being less than the static pressure magnitude.

US Classification:

251366

Abstract:

A valve assembly is provided including at least one pneumatic component and a pneumatic tube assembly fixedly coupled to the at least one pneumatic component. The pneumatic tube assembly includes a pneumatic tube and at least one tube retaining plate. The at least one tube retaining is fixedly coupled about the pneumatic tube by a weld or brazing process. The at least one tube retaining plate further includes a portion positioned in bonding engagement with a bonding surface of the at least one pneumatic component. A retaining bolt mechanically retains the at least one tube retaining plate to the bonding surface. The retaining bolt and the at least one tube retaining plate provide a bonding path between the pneumatic tube and the at least one pneumatic component.
