摘要： An animal watering valve (20, 220) has a diaphragm (64, 264) and a domed valve stem head (120, 320) which provide improved control of the forces aplied to the mating domed valve stem head (120, 320) and which interact to reduce the actuating forces necessary to open the valve (20, 220) by increasing the mechanical advantage of the valve stem (66, 266)/diaphragm (64, 264) combination. The diaphragm (64, 264) and valve stem (66, 266) also interact with each other and with an associated elastomeric ring (68, 268) to provide improved centering of the valve stem (66, 266) on the diaphragm (64, 264) and to permit flow rates through the valve (20, 220) to be adjusted without adversely affecting valve operation. An elastomeric cup shaped shield (70) may also be employed and, if provided, imparts reduced resistance to valve stem (66, 266) deflection and inhibits accumulation of fluid in areas which may be contaminated.
