Abstract:
A regulating valve adapted to be interposed between a pressurized fluid supply whose pressure varies and a fluid applicator from which the fluid is discharged, the valve when actuated functioning to maintain the pressure of fluid fed to the applicator at a substantially constant level regardless of variations in the pressure of said fluid supply, said valve comprising:A. an input section having an inlet coupled to said supply, and having at its end a barrier wall provided with a central port, and an output section having an outlet coupled to said applicator;B. a diaphragm chamber interposed between said input section and said output section; andC. modulating means including a diaphragm in said diaphragm chamber for modulating the size of said port as an inverse function of the varying pressure of the fluid in said input section whereby the pressure of the fluid in the diaphragm chamber is maintained at a substantially constant level, said valve being automatically actuated when the varying pressure of fluid in said input section exceeds a predetermined minimum level, and being automatically closed when said varying pressure is insufficient to achieve valve actuation.
