ABSTRACT:
A variable radial flow rate control valve including a body forming a bore along the longitudinal axis thereof for transporting a fluid through the body, a fixed choke member fixedly positioned about the bore, the fixed choke member forming a fixed aperture, a rotational choke member rotationally positioned about the bore, the rotational choke member forming a rotational aperture radially corresponding to the fixed aperture, wherein a fluid passage is formed radially between the bore and the exterior of the body when the corresponding apertures overlap. The rotational choke member is rotatably, but not axially, moveable in relation to the fixed choke member between variable radial flow rate positions.
