Der Ventilapparat enthält das ausgebohrte Gehäuse B und die Kolben KK1 mit den Oeffnungen bezw. Kanälen α b, von denen a beim Vorrücken des Kolbens die Verbindung der durch den Kolben unterbrochenen Rohrleitung o1 und o2, welche mit beiden Räumen des Bremscylinders communicirt, herstellt und b beim Zurücktreten des Kolbens die Ausströmung von Rohr ο1, d. h. vom todten Raum des Bremscylinders ins Freie öffnet. Bei L schliefst die Luftleitung an. Auf die durch die Kolbenstange K1 zum gröfsten Theil eingenommene Seite des Kolbens wirkt die Luft aus dem todten Raum des Bremscylinders durch das Rohr c c\ Sobald Kolben K durch Druck aus der Hauptleitung L über die Oeffnung von c2 bis zum Ansatz s vorgestofsen ist, tritt die Luft, das Ventil ν hebend, durch c in den todten Raum des Cylinders, und die Bremsen werden gelöst. Gleichzeitig füllt sich durch ο1 α ο2 der Bremsraum mit Luft. Wird die Luft aus der Leitung theilweise abgelassen, so drückt die in dem todten Raum eingeschlossene Luft, durch die Leitung c c1 tretend, den Kolben K nach links und strömt durch o1 b ins Freie. Dann kann die in dem Bremsraum enthaltene Luft sich ausdehnen und zieht durch Verschieben des grofsen Kolbens die Bremsen an.The valve apparatus contains the drilled out housing B and the piston KK 1 with the openings BEZW. Channels α b, of which a, when the piston is advanced, establishes the connection of the pipeline o 1 and o 2 , which is interrupted by the piston and communicates with both spaces of the brake cylinder, and b, when the piston retreats, the outflow of pipe ο 1 , i.e. from the dead one The space of the brake cylinder opens to the outside. At L the air line connects. The air from the dead space of the brake cylinder acts on the side of the piston, which is largely occupied by the piston rod K 1, through the pipe cc \ As soon as piston K has pushed through the opening of c 2 to the attachment s by pressure from the main line L, the air, lifting the valve ν, passes through c into the dead space of the cylinder, and the brakes are released. At the same time, the braking space fills with air through ο 1 α ο 2. If the air is partially let out of the line, the air trapped in the dead space, passing through the line cc 1, pushes the piston K to the left and flows through o 1 b into the open. Then the air contained in the brake chamber can expand and pulls the brakes on by moving the large piston.
