Abstract (en)
[origin: WO0135180A1] A diaphragm (30) operated regulator (2) usable for maintaining a preset gas pressure in a potable storage container, provides effective flow and pressure regulation. The device includes a gas balanced piston-tower (unit 3) that is freely supported, sealed, and operatively connected to a pressure biasing adjustment (26). The diaphragm assembly (11) permits axial movement relationships between valving channels (14), a valving-seal (9), and volume changes that take place in a low pressure chamber (22). The valve (2) converts axial movement of the diaphragm (30) into smooth transitional flow rates by varying the cross sectional areas of ingress and egress from an open valve position to a closed valve position and has the ability to preset maximum flow rates.
