Title: Automatic air venting valve for a pressurised water - piping system
Inventor: ALEXANDER SADOULET MAURICE ALF
IPC: F16L55/00
Filed: 1969-07-21
Abstract: Which can replace the usual arrangement of two separate valves one of which has a large discharge area and operatures at a lower pressure than the other which has a small discharge opening, and in which the incoming water can first drive the air ahead of it out of the valve chamber through the central wide aperture of a vertically displaceable annular plate horizontally supported in the valve chamber, and then through a small bore valve in the cover plate, and then raise the float so that it first restricts the central aperture in the plate sufficiently to cause a pressure rise which raises the plate to an upper position against downwardly projecting annular ribs in the underface of the cover plate sealing the annular opening in the cover plate so that the remaining air is driven out via the small bore valve which in turn is finally sealed off by the float as it is forced up against the sealing of this valve.
