Abstract
Abstract A flow regulator assembly is disclosed. In the preferred and illustrated embodiment, the flow regulator assembly incorporates a clamped transverse disk having an alignment lip thereabout, the disk supporting on the upstream side a centralized projection. The projection supports a resilient body which is expanded by axially compressing the body. It expands to regulate the gas flow in the annular space through the apparatus. Radial expansion narrows an annular flow space between the resilient body and the surrounding housing. A surrounding housing is obtained from the flange terminated pipeline immediately adjacent to the flow regulator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
A gas line flow regulator which comprises: (a) a flange held radially extending transverse plate supported within a pipeline having upstream and downstream faces thereon; (b) a centrally positioned means supported by said transverse plate on the upstream side thereof for regulating the flow of gas through the pipeline, said means including: 1. an elongate centered body; 2. a resiliently expandable means supported by said body having a relaxed and expanded condition wherein the expanded condition is accompanied by a radial outward expansion of said expandable means, and wherein said expandable means further includes;
Claim 2
Dependent Claim
94 words
A gas line flow regulator which comprises: (a) a flange held radially extending transverse plate supported within a pipeline having upstream and downstream faces thereon; (b) a centrally positioned means supported by said transverse plate on the upstream side thereof for regulating the flow of gas through the pipeline, said means including: 1. an elongate centered body; 2. a resiliently expandable means supported by said body having a relaxed and expanded condition wherein the expanded condition is accompanied by a radial outward expansion of said expandable means, and wherein said expandable means further includes;
Claim 3
Dependent Claim
175 words
an exposed outer sealing surface thereon; (c) spaced sealing surface means defined by the inner wall of the pipeline adjacent to said expandable means positioned within the pipeline to define an annular flow space therebetween which is variably constricted by said expandable means on expanding; (d) said transverse plate terminating said flow space and having openings therethrough, there being a first opening means for directing flowing gas in a first direction downstream from said transverse plate and a second opening means therethrough for directing flowing gas in a second direction downstream from said transverse plate; and (e) wherein said first opening means comprise a plurality of holes drilled through said transverse plate, said holes having inlet openings arranged on a circle, and wherein said second opening means comprise a plurality of holes drilled through said transverse plate arranged on a second circle which is larger than the first circle, and said first opening means are directed toward a point of intersection which, if extended downstream of said transverse plate, would intersect within the second circle.
Claim 4
Dependent Claim
175 words
an exposed outer sealing surface thereon; (c) spaced sealing surface means defined by the inner wall of the pipeline adjacent to said expandable means positioned within the pipeline to define an annular flow space therebetween which is variably constricted by said expandable means on expanding; (d) said transverse plate terminating said flow space and having openings therethrough, there being a first opening means for directing flowing gas in a first direction downstream from said transverse plate and a second opening means therethrough for directing flowing gas in a second direction downstream from said transverse plate; and (e) wherein said first opening means comprise a plurality of holes drilled through said transverse plate, said holes having inlet openings arranged on a circle, and wherein said second opening means comprise a plurality of holes drilled through said transverse plate arranged on a second circle which is larger than the first circle, and said first opening means are directed toward a point of intersection which, if extended downstream of said transverse plate, would intersect within the second circle.
Claim 5
Dependent Claim
36 words
The apparatus of claim 1 wherein said transverse plate incorporates first, second and third opening means therethrough wherein said first, second and third opening means are arranged serially outwardly from the center of said transverse plate.
Claim 6
Dependent Claim
50 words
The apparatus of claim 1 wherein said expandable means is positioned adjacent to said spaced sealing surface means and said annular flow space is further defined by a flared and tapered surface located on a surrounding portion of the inner wall of the pipeline adjacent to said sealing surface means.
Claim 7
Dependent Claim
22 words
The apparatus of claim 1 wherein said first and second opening means comprises a plurality of slots drilled through said transverse plate.
