ABSTRACT:
A device for changing the amount of linear movement in a linkage system, preferably for reducing the movement, consists of a hollow body into opposite ends of which a tube and a co-axial rod extend. Attached to the inner end of the rod is a pair of flanges which extend through slots in the tube. A compression spring is lodged in the body between the flanges and an end of the body and a further compression spring is lodged between the flanges and an abutment on the tube at the opposite end of the body. Preferably, the rod passes with clearance through a sleeve forming an extension of the body and a viscous material is provided in the sleeve around the rod to act as a damper to short term movements of the rod.
