Die Erfindung bezieht sich auf ein dosenförmiges Ansauggeräuschdämpfer-Luftfilter-Aggregat für luftansaugende Kolbenmaschinen, insbesondere Brennkraftmaschinen, bei welchem ein radialer äußerer Einlaß in zwei in entgegengesetzter Richtung (der eine im Uhrzeiger-, der andere im Gegenuhrzeigersinn) konzentrisch zum Dosenumfang geführte Interferenzkanäle überleitet und bei welchem diese Kanäle in einen Ringraum einmünden, welcher den der Schalldämpfereinrichtung nachgeschalteten Filtereinsatz umgibt.The invention relates to a can-shaped Intake silencer air filter unit for air-sucking piston engines, in particular internal combustion engines, in which a radial outer inlet in two in opposite directions (the one in the Clockwise, the other counterclockwise) interference channels concentric to the circumference of the can transfers and in which these channels open into an annular space, which the silencer device downstream filter element surrounds.

Ansauggeräuschdämpfer-Luftfilter-Aggregate, welche nicht mit einem radialen äußeren Einlaß, der in zwei in entgegengesetzter Richtung konzentrisch zum Dosenumfang geführte Interferenzkanäle überleitet, ausgestattet sind, sondern vielmehr zwei tangentiale äußere Einlasse aufweisen, deren jeder in je einen in entgegengesetzten Richtungen konzentrisch zum Dosenumfang geführten Kanal die Ansaugeluft einläßt, gehören nicht zu der durch die Erfindung zu verbessernden Gattung der genannten Aggregate.Intake silencer-air filter units, which do not have a radial outer inlet that goes into two interference channels running in opposite directions concentrically to the can circumference are transferred, are equipped, but rather have two tangential outer inlets, each in one in opposite directions concentric to the circumference of the can lets in the suction air, do not belong to the genus of the aggregates mentioned to be improved by the invention.

Es ist bekannt, daß man die durch die Interferenzkanäle erstrebte Interferenzdämpfung in Verbindung mit anderen Dämpfungsprinzipien verbessern kann. Man kann die Kanäle beispielsweise über öffnungen mit einem Resonanzraum koppeln. Von dieser zuletzt genannten, bekannten Möglichkeit macht die Erfindung Gebrauch, und es ist Aufgabe der Erfindung, bei einem dosenförtnigen Aggregat der einleitend genannten Art die erforderliche Größe des Resonanzraumes (etwa das lV4fache des angeschlossenen Hubraumes) ohne störenden Platzaufwand zu verwirklichen. It is known that the interference attenuation aimed for by the interference channels can be combined can improve with other damping principles. The channels can be opened, for example couple with a resonance chamber. The invention makes use of this last-mentioned, known possibility Use, and it is the object of the invention, in a can-shaped unit of the aforementioned Type the required size of the resonance chamber (approximately lV4 times the connected cubic capacity) to be realized without the need for disruptive space.

Dies erfolgt erfindungsgemäß dadurch, daß zwischen der Außenwand der Interferenzkanäle und des genannten Ringraumes einerseits und der diese umgebenden Dosenwand andererseits noch ein besonderer Resonanzraum angeordnet ist, der über Öffnungen mit den Interferenzkanälen gekoppelt ist. Während diese Öffnungen folgerichtig an den Enden des Resonanzraumes liegen, kommen dessen nicht mit Öffnungen versehene Partieen in denjenigen Bereich zu liegen, wo der Resonanzraum den Ringraum begrenzt. Es ergibt sich hierdurch eine für die Dosenform des Aggregates besonders günstige Verteilung und Dimensionierung der Kanäle und Kammern.This is done according to the invention in that between the outer wall of the interference channels and the called annular space on the one hand and the surrounding wall of the can on the other hand a special one Resonance chamber is arranged, which is coupled to the interference channels via openings. During this Openings consequently lie at the ends of the resonance chamber, which do not come with openings provided parts to lie in the area where the resonance space delimits the annulus. It results This results in a particularly favorable distribution and dimensioning for the can shape of the unit of the channels and chambers.

Die Anordnung, Wahl der Anzahl und Bemessung dieser Kopplungsöffnungen, ihrer Größe und der Größe des geschlossenen Resonanzraumes können für jeden Einzelfall leicht durch Versuche ermittelt werden und bereiten keine Schwierigkeiten, wenn man die Kopplungsöffnungen hinreichend groß macht.The arrangement, choice of number and dimensioning of these coupling openings, their size and size of the closed resonance space can easily be determined for each individual case by experiments and do not cause any difficulties if the coupling openings are made sufficiently large.

dargestellten Ausführungsbeispiels weiter erläutert werden.illustrated embodiment are further explained.

Der Lufteintritt, von welchem die Luft aus dem Raum unter der Motorhaube oder aus einer thermostatisch gesteuerten Temperaturregelanlage gesaugt wird, ist mit 10 bezeichnet. Die Luft tritt über den Einlaß 10 in die Interferenzkanäle 11 α und 11 b. Diese Teilströme der Ansaugluft münden an den Stellen 12 und 13 in den zentralen Ringraum 19, welcher den Filtereinsatz 14 aus geriffeltem Papier umgibt. Die Luft tritt dann radial durch den Filtereinsatz 14 und verläßt den Filter durch den Auslaß 15, der in bekannter, nicht dargestellter Weise auf dem Vergasersaugstutzen angeflanscht sein kann.The air inlet, from which the air is sucked in from the space under the engine hood or from a thermostatically controlled temperature control system, is denoted by 10. The air passes through the inlet 10 into the interference channels 11 α and 11 b. These partial flows of the intake air open at points 12 and 13 in the central annular space 19, which surrounds the filter insert 14 made of corrugated paper. The air then passes radially through the filter insert 14 and leaves the filter through the outlet 15, which can be flanged onto the carburetor suction connection in a known manner, not shown.

Erfindungsgemäß ist nun ein äußerer geschlossener ringförmiger Resonanzraum 16 zwischen der Außenwandung 11 der Interferenzkanälella und 116 bzw. des zentrischen Ringraumes 19 einerseits und der Dosenwandung 20 andererseits gebildet. Kopplungsöffnungen 17 und 18 sind in den Abschnitten 11a und 11 b der Wand 11 aus Vertikalschlitzen nach außen gedrückt.According to the invention, an outer closed ring-shaped resonance space 16 is now formed between the outer wall 11 of the interference channels and 116 or the central annular space 19 on the one hand and the can wall 20 on the other hand. Coupling openings 17 and 18 are pressed outward from vertical slots in sections 11a and 11b of wall 11.

Es wurde gefunden, daß diese Öffnungen im Abstand von je einem Drittel Kanallänge von Einlaßmitte entfernt mit besonders guter Wirkung anzuordnen sind, wobei die öffnungen zweckmäßig die ganze Höhe der zylindrischen Kanalwand 11 und eine Breite von etwa 13 mm einnehmen und zweckmäßig nach außen und in Strömungsrichtung nach hinten gedrückt sein können.It has been found that these openings are at a distance of one third each channel length from the inlet center are to be arranged remotely with particularly good effect, with the openings expediently the whole Take the height of the cylindrical channel wall 11 and a width of about 13 mm and expediently after can be pressed outwards and backwards in the direction of flow.

Das Volumen des geschlossenen Resonanzraumes ist vorzugsweise etwa gleich dem lV4fachen Hubraum des angeschlossenen Motors.The volume of the closed resonance chamber is preferably approximately equal to four times the cubic capacity of the connected motor.
