Abstract

Improvements in electro-pneumatic compressed air brakes for railway vehicles, of the type comprising a main air pipe that regulates, pneumatically by its behavior of the pressure, a brake control valve, which monitors the pressure load of a brake cylinder from a source of air under pressure, through a braking nozzle, or its evacuation, through a release nozzle, into the atmosphere and with a relay valve carrying a control piston, monitored in its air charge to pressure by a magnetic braking and release valve, which stops the main air pipe shows a valve piece monitoring an evacuation into the atmosphere and a supply of air, under pressure from a source of air under pressure, characterized in that the magnetic brake valve, develops as a double-seat magnetic valve, and monitors the supply of pressurized air from a source of air under pressure, or the evacuation to the atmosphere of a first supply chamber towards one of the sides of the control piston, and the magnetic release valve, also develops as a double-seat magnetic valve, monitors the supply of air under pressure from the source of compressed air, or the evacuation into the atmosphere of a second supply chamber to the other side of the control piston, because the control piston on the side of the first control chamber is coupled, through stop couplings, with two plunger valves under the spring force in the closing direction, of which, one plunger valve, is towards the main air pipe, and the other plunger valve on one bridge for the release nozzle, and because the control piston for this, is coupled symmetrically on the side of the second control chamber, also through stop couplings, with two other plunger valves under the spring force in the closing direction, of which, a piston valve is disposed in the evacuation from the main air pipe to the atmosphere, and the other piston valve in a bridge for the braking nozzle.
