ABSTRACT:
An electrically actuated valve for incremental fluid flow rate control is disclosed. The valve is comprised of a valve body having an interior with a planar outlet surface against which a rectilinear valve element is slidingly operated. The valve body includes an inlet orifice and an outlet orifice in the planar outlet surface for fluid flow through the valve body. The valve element has an orifice therethrough controlling flow through the outlet orifice in accordance with the position of the valve element, which is linearly actuated by a rotary stepper motor. Linear actuation of the valve element by the rotary stepper motor is accomplished by a shaft extending through and rotating in bearings at opposing ends of the valve body. A drive key on the shaft interfits a corresponding slot in the valve element and converts rotary motion of the shaft to linear motion of the valve element.
