Description

Drucklufthupe, insbesondere für Kraftfahrzeuge mit einer zwischen zwei kreisförmigen Stutzen festgeklemmten, am Rande ausgezahnten Membran, bei der das Überströmen der Blasluft von der Oberseite der Membran nach der Unterseite durch mehrere Segmentöffnungen der Membran erfolgt Die Erfindung bezieht sich auf eine Drucklufthupe, insbesondere für Kraftfahrzeuge, mit einer zwischen zwei kneisförrnigen Stutzen festgeklemmten, am Rande ausbezahnten Membran, bei der' das Überströmen der Blasluft von der- Oberseite der Membran nach der Unterseite durch mehrere S,eg-mentöffnungen der Membran Erfolgt.Compressed air horn, in particular for motor vehicles with an between two circular nozzles clamped, on the edge serrated membrane, at the the overflow of the blown air from the top of the membrane to the bottom several segment openings of the membrane takes place. The invention relates to a Compressed air horn, especially for motor vehicles, with a kneis-shaped horn between two Nozzle clamped, toothed membrane at the edge, in which 'the overflow the blown air from the top of the membrane to the bottom through several S segment openings the membrane takes place.

Die Erfindung besteht darin, daß die-Membran zwischen den beiden Stutzen nicht längs einer Ringfläche, sondern durch, Ausbildung von Ringnuten in den Klemmflächen längs einer Ringlinie festgeldemmt ist, wodurch das Schwingen der Membran unter Verringerung schädlicher Biegungsbeanspruchungen an der Klemmstelle erleichtert wird.The invention consists in that the membrane between the two nozzles not along an annular surface, but through the formation of annular grooves in the clamping surfaces is fixed along a ring line, whereby the oscillation of the membrane is under Reduction of harmful bending stresses at the clamping point facilitated will.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An exemplary embodiment is shown in the drawing.

Abb. i stellt links einen senkrechten 1\ütte-lschnitt, rechts eine Ansiat dar. Abb.2 ist eine Draufsicht des Austrittsstutzens reit aufgelegter Scheibe.Fig. I shows a vertical section on the left, one on the right Ansiat. Fig.2 is a top view of the outlet port with the disc in place.

i ist der Lufteintrittsstutzen, 2 der Luftaustrittsstutzen. Beide. sind durch Gewinde verbunden. Eine Metallmembran 3 ist in bekannter Weisse mit Randzähnen 4 und mit Radialschlitzen 8 versehen.. Durch Ausbildung von Ringnuten io in dem Luftein- und Luftaustrzttsstutzen i und 2 sind schmale Kanten 5 und 6 gebildet, zwischen denen die Zähne 4 der Membran 3 festbeklemmt sind. Die Membran 3 ist zu den umgebenden Gehäusen 12 so angeordnet, daß Segnientschlitbe 7 für den Luftdurchtritt gebildet werden. Auf der Stirn 9 eines im Stutzen 2 axial verlaufenden Rohrstückes liegt die Metallschelbbe 3 auf. Sie wird beim Durchtritt der Luft durch dnle Einrichtung in Schwingungen versetzt und schlägt dabei auf der Stirn fläche 9 auf. Durch die linienförmige Klemmu;ng der Metallmembran 3 wird ihr Schwingen sehr erleichtert, da an der Klemmstelle 5, 6 im Gegensatz zu den bisher bekannten Ausbildungen schädliche Biegungsbeanspruchungen sehr herabgesetzt sind.i is the air inlet nozzle, 2 is the air outlet nozzle. Both. are connected by thread. A metal membrane 3 is in known white with peripheral teeth 4 and provided with radial slots 8 .. By forming annular grooves io in the Air inlet and outlet nozzles i and 2 are narrow edges 5 and 6, between which the teeth 4 of the membrane 3 are clamped. The membrane 3 is closed the surrounding housings 12 arranged so that Segnientschlitbe 7 for the passage of air are formed. On the forehead 9 of a pipe section extending axially in the nozzle 2 the metal shell 3 lies on. It is when the air passes through a thin device set in vibration and strikes it on the face 9 on. Through the linear clamping of the metal diaphragm 3 makes it much easier to swing, because at the clamping point 5, 6, in contrast to the previously known designs, harmful Bending stresses are very reduced.

Die Drucklufthupe arbeitet in der Weise, daß bei ihrem Ingangpetzen die Luft zunächst gegen den mmttlenen Teil der Metallscheibe 3 gedrückt wird. Die Luft verteilt sich dann gleichförmig gegen den Rand der Scheibe 3 hin, tritt auf die andere Scheibenseite durch die Segmentschltitze 7 übler und beeinfiußt so günstig die Schwingungswirkung und fließt dann durch die ringförmige Ausnehmung des Abflußs;tutzens über die Stfnkante 9 des Rohrstückes ab.The air horn works in such a way that when it is started the air is first pressed against the mmttlenen part of the metal disc 3. the Air is then distributed uniformly towards the edge of the pane 3, occurs the other side of the pane is worse due to the segment slots 7 and thus has a favorable effect the vibratory effect and then flows through the annular recess of the drain; tutzens over the Stfnkante 9 of the pipe section.
