Description

Rohrpostweiche Um beim Durchgang einer Rohrpostbüchse durch eine Weiche Luftverluste zu vermeiden und eine größere Sicherheit für den richtigen Durchgang der Büchse zu schaffen, wird gemäß der Erfindung die um einen Drehpunkt bewegliche Weichenzunge, die zwei im spitzen Winkel zueinander stehende schalenförmige Leitflächen besitzt, derart ausgebildet, daß die schalenförmigen Leitflächen zusammen mit der Wandung der Weichenkammer in jeder Lage eine rohrförmige Durchfahrt durch die Weiche herstellen. Die Büchse hat auf diese Weise eine ebenso sichere Führung wie im Rohr selbst. Zugleich wird auch ein Luftverlust und Druckabfall vermieden, der gerade an dieser Stelle störend wirken kann.Pneumatic tube switch Um when a pneumatic tube can pass through a switch Avoid air leakage and greater security for the correct passage To create the sleeve, according to the invention, it is movable about a pivot point Switch tongue, the two bowl-shaped guide surfaces at an acute angle to one another has, designed such that the cup-shaped guide surfaces together with the Wall of the switch chamber a tubular passage through the switch in every position produce. In this way, the bushing is just as safe as it is in the pipe itself. At the same time, an air loss and pressure drop is also avoided can have a disturbing effect at this point.

Die Erfindung ist auf der Zeichnung in einer Ausführungsform in Abb. r bis 3 dargestellt.The invention is shown in one embodiment of the drawing in Fig. r to 3 shown.

In der Weichenkammer d, deren Querschnitt in Abb.3 ersichtlich ist, ist um die Achse .e drehbar die Weichenzunge S angeordnet, die erfindungsgemäß mit zwei im spitzen Wink -e1 zueinander stehenden Leitflächen si, s2 versehen ist. Entsprechend der Wölbung der schmalen Kammerlängsseiten, die dem Fahrrohrquerschnitt angepaßt -ist, sind die Leitflächen si, s2 ebenfalls eingewölbt, so daß sie der durchfahrenden Büchse einen Kanal von gleicher Form wie die Schenkelrohre b, c selbst darbieten. Hat die Weichenkammer rechteckigen Querschnitt, so würden die Leitflächen si, s. als ebene Flächen auszubilden sein.In the switch chamber d, the cross-section of which can be seen in Figure 3, the switch tongue S is arranged so that it can rotate about the axis .e, which according to the invention with two guide surfaces si, s2 standing at an acute angle -e1 to one another is provided. Corresponding the curvature of the narrow long sides of the chamber, which is adapted to the tube cross-section -is, the guide surfaces si, s2 are also arched so that they pass through Bushing a channel of the same shape as the leg tubes b, c present themselves. If the switch chamber has a rectangular cross-section, the guide surfaces si, s. be designed as flat surfaces.
