Abstract
A fluid pressure regulator of compact construction including an improved diaphragm-valve assembly interposed between a flow body (20) and a second body cap element (50). The flow body has an inlet and outlet passage (22, 30) and a valve cavity with a centrally disposed ported valve insert (40) to allow the regulated passage of fluid. Mounted to the flow body, the cap element confines a diaphragm (70) of the diaphragm-valve assembly and houses an adjustable coil-spring (120) biased against the assembly. The diaphragm-valve assembly includes a ring-shaped diaphragm element (70) interlocated between a circular element (75) central to the diaphragm and a diaphragm compression limiting clamp plate ring (90). The circular element has a central recess (78) over the valve insert which houses a spring- backed self-aligning ball valve element (80) having a flat chordal surface (82) adjacent the insert. A convolute (100) in the diaphragm element provides a more consistent effective area in relation to the valve stroke during operation improving pressure regulation and reducing stretching of the diaphragm preventing tearing, rupture or undesirable hysteresis.
