ES225140U - Improved brake actuator for vehicles (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Brake actuator device for vehicles, improved, characterized in that it is constituted by a cylinder comprising two axially consecutive expandable chambers, one of which contains suitable means of brake actuation by fluid pressure, while the other chamber includes a piston provided with a central stem related to the possibility of axial sliding in it, the stem of which passes through the dividing wall between the two expansion chambers with an airtight fit, so as to remain at its related end, as a pusher, with the aforementioned actuating means. Of brake, while at the rear end is confronted with a stop element that is mounted so adjustable on the piston to empty relative to it the relative axial position of stop of the rod, said piston being subjected on the one hand to the action constant of a spring that tends to move in the direction of braking, and on the other able to receive fluid pressure against the action of said spring; all this in such a way that under the normal conditions of pressure of the actuating fluid of the brake means, said piston of the second chamber is retracted in power, to act auxiliaryly to the braking means if the fluid pressure fails, being maneuverable in such a state abnormal the braking release by the retraction of the adjustable stop, which is accessible from the outside.
