Abstract
An improved assembly for use in an in-line starter valve. A flexible material system in the form of a flexible belt is used to translate motion from a manually operable wrench shaft to a piston rod in order to render an in-line starter valve to a closed, partially opened, or an extreme opened position. When the wrench shaft is manually rotated, tension is imparted on the flexible band which, in turn, translates tension to a piston rod which then travels longitudinally resulting in the opening or closing of the in-line starter valve. An index mark on a handle of the wrench shaft indicates the closed, partially opened, or extreme opened position of the in-line starter valve. The use of the flexible belt affords greater durability, less weight, and less costly production than the prior art assemblies.
