Patent ID: 7533689

Claim:
An excess flow control valve including: a cylindrical open ended barrel having upstream and downstream extremities, the downstream extremity formed exteriorly with a plurality of axial ribs spaced thereabout, the ribs being configured with radial cutbacks defining upstream facing stop surfaces and rib stubs projecting therefrom and cooperating to define a circular pattern, the barrel further including adjacent upstream extremity a plurality of radial stop ring segments spaced thereabout to form between the respective circumferential ends thereof a selected number of clearance passages having a predetermined circumferential width, the body further including respective pairs of teeth disposed medially on the exterior periphery thereof and spaced apart the predetermined circumferential distances to form therebetween the selected number of slider tracks, the slider tracks being rotated relative to the respective clearance passages to be disposed out of axial alignment therewith; the barrel further being formed adjacent its downstream end, a spring step surface facing upstream; a poppet formed with a cylindrical bearing ring and a semi-spherical cap, the cap connected with the guide ring by longitudinal braces spaced equidistance about the ring to cooperate in forming between the ring and cap respective inlet ports, the ring including on its inner surface thereof the selected number of axial sliders having a width corresponding with the predetermined circumferential distance and configured to be received in sliding engagement through the respective clearance passages and so configured as to allow the cap to then be rotated relative to the barrel to be disposed in the respective tracks between the respective pairs of teeth; the ring being formed on one end with a downstream facing spring stop surface; a coil spring received over the body and interposed between the spring stop surfaces; the body further formed on its downstream end with an external O-ring gland; an anchor sleeve receiving the body and formed on its downstream extremity with a radially in tumed anchoring flange and formed on its upstream extremity with an outwardly rolled anchoring bead.
