Abstract
Variable flowrate regulators of this invention r comprises a regulator body having a fluid transport chamber disposed therethrough. Fluid inlet and outlet ports are in fluid flow communication with the chamber, and a valve seat is positioned at one end of the chamber. A diaphragm housing is attached to the body and has a diaphragm chamber in fluid flow communication with the fluid transport chamber. A diaphragm is disposed within the diaphragm chamber. A one-piece poppet assembly is attached to the diaphragm and is disposed within the body. The poppet assembly comprises a head that has a diameter sized greater than that of the valve seat for providing a leak-tight seal thereagainst when placed in a closed position. The poppet assembly also comprises a plurality of orifices positioned downstream from the head for passing fluid into the fluid transport chamber when the head is unseated from the valve seat. The plurality of orifices is positioned concentrically within the fluid transport chamber.
