Abstract:
1. Security braking device mounted between a hydraulic fluid tank and actuation members capable of acting on braking members, comprising: a loading and non-compression position locking mechanism for a master cylinder hydraulically connected to the tank and to the braking members, said mechanism being dependent upon a control member for unlocking the mechanism in order to concomitantly urge the master cylinder to apply a predetermined hydraulic pressure for acting on the braking members, wherein the mechanism includes: an articulated lever connected via a link rod system to one end of a body of the master cylinder; a rocking member coupled, in an articulated way, to a rod of a piston of the master cylinder, said rocking member being dependent upon a resilient return member capable of storing energy; and a swivelling hook connected to the control member for engaging with a part of the rocking member to hold the rocking member in a locked position corresponding to non-compression of the master cylinder, said hook being returned to the locked position by a spring.
