Abstract
A clutch assembly formed as a circular split bobbin assembly for resisting reciprocating motion of a shift rod or dart valve stem in a bypass plunger. The split bobbin may include at least one circumferential groove disposed in its outer radius, and a tension band member disposed in each circumferential channel to secure the split bobbin assembly around the shift rod or valve stem and wherein the tension band member has a cross section aspect ratio R<1.
Claims8
A clutch assembly for resisting the reciprocating motion of a shift rod or dart valve stem in a bypass plunger, comprising:
- a clutch body formed as a circular split bobbin assembly having first and second cylindrical halves;
- at least one circumferential channel disposed in a surface defined by the outer radius of the split bobbin assembly;
- and
- a tension band disposed in each circumferential channel to secure the split bobbin assembly around the shift rod or dart valve stem wherein the outer radius of each tension band is less than the outer radius of the split bobbin assembly and wherein each tension band has a gap in its circumference and a cross section aspect ratio R<1.
