Abstract
Braking corrector of the type incorporating a simple or differential piston provided with a passage joining together the inlet and outlet chambers, a valve controlling communication through the passage, a return spring joined to a component, which is movable as a function of the vehicle load, to return the piston to a rest position, and an abutment holding the valve open in this same position. The invention provides for the corrector (10) to be provided with an elastic device (40) for limiting the travel of the piston (16) towards its rest position, this device only coming into action after the valve (24) has lifted from its seat (26) and subsequently modulating the retraction of the piston as a function of the thrust which is transmitted to it by the return spring (36). Applicable to the braking systems of motor vehicles.
