Abstract

Starting with a manually actuated pump 1 acting on the brake cylinder 5 under normal service conditions, it consists in connecting said manually actuated pump 1 to an accumulator 8 via a conduit 9 and with the interposition of a one-way valve 10 acting as non-return to the pump 1, said accumulator 8 in turn being connected to the brake cylinder 5 via a second conduit 12 in which there is an electrovalve 13 which is kept closed under normal operation of the locomotive by virtue of the action of the locomotive driver on a pedal 14 which has to be kept permanently engaged so that, when, for any reason, actuation of said pedal 14 ceases, the electrovalve 13 opens and the accumulator 8 supplies pressure to the cylinder 5 of the brake, generating emergency deceleration.
