| 发明名称 | Sucker rod guide | ||
| 摘要 | A polymeric rod guide for a sucker rod, said polymeric rod guide having a body surrounding and coaxial with the sucker rod and molded in fixed contact with the rod. The body having a polygonal cross-section and a plurality of blades longitudinally disposed and extending from the body, each blade having a pair of planar longitudinal side walls and an exterior longitudinal edge, each of said blades having a first blade face disposed between a first terminal end of the blade and the exterior longitudinal edge and a second blade face disposed between a second terminal end of the blade and the exterior longitudinal edge, and an area of the body between the longitudinal side wall of a first blade and the longitudinal side wall of an adjacent second blade defines a trough having a plurality of planar surfaces. | ||
