ABSTRACT:
A spring-loaded braking cylinder has a rapid release mechanism which disengageably connects the spring-loaded piston with the piston rod. A damping mechanism damps the relative movement between the piston and the piston rod which occurs upon release of the coupling between the spring-loaded piston and the piston rod. The piston rod is coupled to the piston by a transverse pin a portion of which projects into a transverse slot on the piston rod and another portion of which is movable within an L-shaped slot on the piston rod. An adaptor connected to the pin has a flange which acts as a piston within a closed chamber formed with the piston rod and filled with fluid. The spaces on both sides of the piston-like flange are interconnected by throttle passages. The damping mechanism may also comprise a rotary pump structure in parallel with a clutch between the piston rod head and the actuating member where the releasable coupling is constructed as a threaded spindle and clutch nut threaded into each other by means of an non-self-locking thread of a linkage adjustment mechanism and a releasable coupling is provided between the piston rod head and an actuating member extending from the adjustment mechanism.
