Abstract

Improvements in braking device by means of pressure for railway vehicles, especially brake by means of pressure for rail vehicles, with a spring accumulation brake cylinder whose piston is loaded on the one hand by the force of a spring and on the other hand, acting in the direction of release of the brake, by the pressure of the pressure medium in a driving enclosure, the driving enclosure being connected to the output connection of a double check valve, one of whose input connections is linked to a arbitrarily operable pressure medium pump, characterized in that the connecting line from the pressure medium pump to the double check valve, a distributor valve is provided, which is governed by the pressure at the source of the reserve pressure medium, only leaves the passage through the junction duct, when a certain amount of pressure is exceeded in this source of the med io reserve pressure, and if not blocked this step and links to a return pressure medium constantly pressure-free, or with the atmosphere, the section of the connecting duct that goes from the distributor valve to the double check valve.
