ABSTRACT:
A metering valve having a deflectible beam for controlling fluid flow through an inlet port wherein a selected orifice disc, which may be any one of a plurality of orifice discs having different size orifices, is disposed in aligned relationship with the inlet. The deflectible beam may be carried on the orifice disc. The orifice disc may be removably secured within the valve by separable portions of the wall structure thereof. The outlet may be arranged to extend around the periphery of the orifice disc and opens to the flow chamber within the valve closely adjacent the beam to provide effective minimum axial extent of the valve. The beam deflecting structure includes a spring. One spring retainer at an outer end thereof is provided with a conical surface engaging a threaded adjusting element for minimum transfer of rotational force to the spring during the adjustment of the metering valve. The other spring retainer may be fully cylindrical for improved sliding action with a complementary cylindrical portion of the valve flow chamber.
