Title: Jam proof piston

Abstract: An improved jam-proof control including a cylinder-piston assembly in which the piston is controllably positioned within the cylinder to perform the control function and in which the piston rod which extends through the cylinder wall is enveloped by a deformable sleeve so that when the piston rod is deformed by sharp impact, the piston rod is permitted to continue to reciprocate within the housing due to the deformation, either due to frangibility or softness, of the piston rod sleeve.
