Abstract
A tension compensation assembly for a mechanical control cable. The tension compensation device has a housing with opposing ends. First and second sections of the control cable pass through but are attached at each end of the housing such that the sheaths of each section are coupled to the housing and reciprocable cable coaxially disposed in each control cable section extend into the housing. The cables are attached to opposing ends of a reciprocably disposed capsule or spring caps generally enclosing a spring. In operation, the capsule moves slidably within the housing over a predetermined travel and tension for the cables. However, if an over-tension condition is experienced, the capsule may bottom out at an end of the housing and the spring will either compress or extend, depending upon its design, thus allowing the effective length of the control cable assembly to increase, thus preventing the stretching or breaking of the cables or damage to cable end fittings.
