Abstract
In a brake cylinder there is a reciprocating piston from which extends a non-rotatable sleeve surrounding a co-axial non-rotatable axially displaceable threaded shaft upon which is threaded a coupling nut. A pair of rotary couplings are provided on opposed sides of the coupling nut with the sleeve and the rotary couplings are actuable by axial displacement of the coupling nut. A stop ring is axially displaceable on the coupling nut and is supported opposite to the braking direction by a fixed stop. A spring has one end acting against the stop ring and its other end acting against an abutment on the sleeve. A second stop on the coupling nut is spaced rearwardly of the first stop a distance approximately equal to the contact stroke of the vehicle brake when the resetting device is in the inoperative position.
