Claims (1)

Patent-Anspruch:Patent claim: Ein Geschwindigkeitsanzeiger, bei welchem, wie im Patent No. 31540, mittelst eines in beiden Drehrichtungen gleichartig wirkenden Ventilators Druck in einer Luftleitung erzeugt wird, dieser Druck die Höhenlage der Flüssigkeitsspiegel zweier communicirenden Röhren verändert und infolge dessen die Bewegung eines das Anzeigen bewirkenden Schwimmers hervorruft, bei welchem Geschwindigkeitsanzeiger aber hier die Drehrichtung statt mittelst einer federnden, den Stromkreis einer elektrischen Anzeigevorrichtung schliefsenden Metallplatte durch die Druckänderung in einer Luftleitung angezeigt wird, welche mittelst" eines durch den Umsteuerungsmechanismus bewegten Kolbens oder Gummikissens hervorgerufen,wird.A speed indicator in which, as in patent no. 31540, by means of an in Fan acting in the same way in both directions of rotation generates pressure in an air line this pressure becomes the height of the liquid level of two communicating tubes changed and as a result the movement of a swimmer causing the display causes which speed indicator but here the direction of rotation instead of mean a resilient metal plate that closes the circuit of an electrical display device is indicated by the change in pressure in an air line, which by means of one caused by the reversing mechanism moving piston or rubber cushion is.
