ABSTRACT:
A diaphragm and valve assembly using the same for controlling fluid flow from a pressurized source of fluid. The diaphragm is longitudinally perforated at a peripheral area to permit axial flow of the fluid past the diaphragm, and is radially perforated to provide ambient atmospheric pressure on the downstream side of the diaphragm. The valve assembly is of the type which regulates fluid flow in response to pressure changes occurring at the fluid source which pressure changes result from ambient temperature changes thus establishing a preset fluid flow rate which persists throughout a wide range of ambient temperatures.
