Abstract

Improvements in compressed air brake devices for railway vehicles, with a main air pipeline, with a conduction channel connected to it through an arbitrarily actionable shut-off valve, with a three-pressure control valve that governs directly or indirectly the pressure of the brake cylinder, of the type comprising a driving chamber connected directly to the driving channel and a constant pressure chamber connected to the driving channel through a closed control valve as there is no pressure in the driving chamber and a pressure chamber of the brake cylinder, with an air reservoir that feeds the pressure chamber of the brake cylinder through an inlet valve of the three-pressure control valve, which is downloadable to the atmosphere by means of an output valve coupled, operable in the opposite direction to the shut-off valve, and with a discharge valve having a valve seat of small diameter surrounding a space that is connected to the constant pressure chamber, which is closed by a valve seal arranged in a piston of greater diameter, and which is surrounded by an annular space delimited by the piston, communicable with the atmosphere, characterized in that the piston on the side opposite to that of the valve seal is under the action of the pressure of the air reservoir and because the annular space is communicated with the atmosphere, at least when the valve is open. Outlet valve. (Machine-translation by Google Translate, not legally binding)
