Abstract

Improvements in compressed air braking devices for rail vehicles, of the type comprising a main air line, with a feed channel connected to it through an arbitrarily actionable blocking member, a three pressure distribution valve that governs direct or indirectly at a pressure of the brake cylinder, which comprises a constant pressure chamber chargeable in the supply channel through a closed control valve when there is brake cylinder pressure and a brake cylinder pressure chamber, with a reserve air reservoir chargeable from the supply channel through a non-return valve, which is downloadable to the atmosphere by means of a discharge valve coupled and operable in contradiction with the blocking valve, and with a maximum pressure limiter that limits at a maximum value that can be fixed to the pressure rise in the brake cylinder, in a connection between the reserve air tank and an inlet valve of the three-pressure distribution valve connected to the pressure chamber of the brake cylinder, being driven in the closing direction of the maximum pressure limiter, by the pressure in the connecting pipe that goes from the maximum pressure limiter to the valve, a switching piston of the maximum pressure limiter, characterized in that the connecting pipe is connected to the reserve air reservoir through an anti-return valve that opens in this sense of current.
