PATENT-AiTSPRUCH:PATENT CLAIM:

Ein beim Umlegen des inneren Handgriffes von Noththüren zu öffnender Verschlufs der Luftleitung von Bremsen, gekennzeichnet durch einen mit einer als Luftdurchlafs dienenden Bohrung (k) versehenen Kolbenschieber (b), welcher in der Ruhestellung, wobei die Luftleitung (g) abgesperrt ist, durch eine Feder (e) und nach dem durch das Umlegen des Handgriffes der Thür bewirkten Verschieben, wobei die Leitung (g) durch die Bohrung (k) und die Öeffnungen eines Siebes (i) des Schiebergehäuses (c) mit der Aufsenluft in Verbindung tritt, durch einen unter dem Einflüsse einer Feder (m) stehenden, von Hand auslösbaren Sperrstift (I) in dieser Stellung gehalten wird.A closure of the air line of brakes which can be opened when the inner handle of emergency doors is turned, characterized by a piston slide (b) provided with a bore (k) serving as an air passage, which in the rest position, whereby the air line (g) is blocked, by a Spring (e) and after the movement caused by turning the handle of the door, the line (g) communicating with the outside air through the bore (k) and the openings of a sieve (i) of the valve housing (c) a manually releasable locking pin (I) under the influence of a spring (m) is held in this position.

CLASS 20 /.

When the door is opened, a pusher is used to attach the air brake to the pipe connected air outlet valve and opened in this position by a Hand held releasable lock.

Fig. Ι shows the device in the vertical Cut,

Fig. 2 in view and

Fig. 3 in horizontal section.

When the door is opened by turning the door handle, the pusher α acts on the piston b, which is displaceable in the cylinder c attached to the inside wall of the car.

The piston b is secured against rotation by a square extension d and is pressed against the sealing ring / by a helical spring e. The cylinder c is connected on one side to the air pressure or air suction line g , while on the opposite side it has a bore h which communicates with the outside air and which is closed to protect against the ingress of impurities through a sieve i can. The piston b has a through-hole k which, when the pusher α BEZW when opening the door. When the handle is turned, the piston in the cylinder c is displaced and communicates with the air line g and the bore h , so that the brake is activated.

So that the connection between the brake line and the outside air remains secured even after the pusher λ has returned, the piston b, as soon as it has covered its full stroke, is held in place by the pin / a snap spring in that this pin is in this position in the Piston rod η screwed-in nut ο snaps into place.

By lifting the snap spring m and the locking pin / the piston rod is released, so that the piston b moves through the spring e in the rest position, respectively. is pressed against the sealing ring f.
