초록

A pressure balancing foam valve includes a body having a liquid inlet at one end and a liquid outlet at an opposite end, and having an annular passage therethrough. A first stage pressure regulating assembly is disposed within the annular passage of the valve and includes a shaft that is attached at a first end to the liquid inlet. A one-piece pressure disc is slidably disposed on the shaft. The disc is urged into a seated position against an end portion of the liquid inlet by a spring interposed between the pressure disc and a second end of the shaft. T...

청구항

A method for producing a differential pressure within a valve comprising the steps of: passing liquid that enters an inlet portion of the valve through an annular passage and over a slidably displacable pressure disc, wherein the position of the pressure disc within the annular passage is controlled by a spring means acting to urge the pressure disc into a seated condition against an edge portion of the passage to prohibit flow therethrough, wherein the pressure disc is unseated and moved axially away from the inlet portion with increasing liquid pressur...
