Abstract
A valve for the accurate control of fluid flowing through the valve. The valve has a valve body and a flow control mechanism. The valve body is a two-part body having a fluid flow section and a valve adjustment section. The fluid flow section has a fluid flow cavity. The fluid flow cavity further includes a flow control orifice area, which flow control surface being smaller in cross-sectional area than the fluid flow cavity. The flow control mechanism is able to vary the length of its major axis via a force provided by the valve actuator. As the major axis of the flow control mechanism decreases, the minor axis of the flow control mechanism increases at an amplified rate, said increase in the minor axis of the flow control mechanism accomplishes flow control and in combination with the valve actuator, flow control and fluid modulation.
