Abstract

A dual orifice variable flow rate valve (100, 700, 900) is provided. The dual orifice variable flow rate valve (100, 700, 900) includes a valve body (110, 710, 910) with a first fluid port (112, 712, 912) and a second fluid port (114, 714, 914), the first fluid port (112, 712, 912) having a first fluid orifice (112a, 712a, 912a) and a dual valve member (120, 720, 920) disposed in the valve body (110, 710, 910). The dual valve member (120, 720, 920) includes a first valve member (122, 722, 922) disposed in the valve body (110, 710, 910), the first valve member (122, 722, 922) having a second fluid orifice (122e, 722e, 922e) fluidly coupled to the first fluid port (112, 712, 912) and a first distal end (122a, 722a, 922a) proximate the first fluid orifice (112a, 712a, 912a) and a second valve member (124, 724, 924) disposed in the valve body (110, 710, 910) proximate the second fluid orifice (122e, 722e, 922e) in the first valve member (122, 722, 922). The dual orifice variable flow rate valve (100, 700, 900) also includes an actuator (130, 730, 930) configured to move the second valve member (124, 724, 924) relative to the first valve member (122, 722, 922) to control a fluid flow between the first fluid port (112, 712, 912) and the second fluid port (114, 714, 914) through the second fluid orifice (122e, 722e, 922e) in the first valve member (122, 722, 922).
