Abstract
A rod guide 10 for positioning on a sucker rod includes a sleeve-shaped guide body 12 and two or more spiraling vanes 14, 16 each extending radially outward from the sleeve-shaped body, with each vane spiraling about the body and defining a flow path between circumferentially spaced vanes. Each vane has a forward portion 24 spiraling in a forward direction, and a backward portion 26 spiraling in a backward direction rotatably opposite the forward direction. The rod guide may be used for either reciprocating rod or rotating rod applications.
