この発明は、内燃機関の吸気の清浄等に用いる
エヤクリーナの共鳴室に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resonance chamber of an air cleaner used for cleaning intake air of an internal combustion engine.
内燃機関の吸気は、間欠的に急激に行われるの

すると、非常に長い共鳴室が必要になる。オート
バイのように、限られた場所にエヤクリーナを設
置するものでは、長い共鳴室を設けることが不可
能で、低周波域の騒音の低減が困難である。 Since air intake in an internal combustion engine occurs rapidly and intermittently, noise is generated each time the engine takes air at the suction port of an air cleaner connected to the intake pipe. Some air cleaners have a resonant chamber connected to the outer casing to reduce noise through resonance, but in order to attenuate the low frequency range, a very long resonant chamber is required. In vehicles such as motorcycles in which the air cleaner is installed in a limited area, it is impossible to provide a long resonance chamber, making it difficult to reduce noise in the low frequency range.
この発明は、かかる問題を解決するもので、以
下図面に示す本発明の実施例について説明する。 The present invention solves this problem, and embodiments of the present invention shown in the drawings will be described below.

のである。 In FIGS. 1 and 2, the cleaner outer casing 1 is
An inlet 2 and an outlet 3 are provided, and a cleaner element 4 is installed inside.The cleaner element 4 removes dust from the air taken in from the inlet 2, cleans it, and then sends it to the outlet 3.
send it to Therefore, the present invention provides a cleaner outer casing 1.
A cylindrical resonance chamber 5 is provided protrudingly on one side, and a torsion plate 6 is inserted into this resonance chamber 5. FIG. 3 shows another embodiment of the present invention, in which a torsion plate 6 is installed in the resonance chamber 5 of FIG.
In addition, an inner tube 7 is inserted through the center of the torsion plate 6. FIG. 4 shows still another embodiment of the present invention, in which a communicating hole 8 is bored in the inner tube 7 of FIG. 3.
作用について説明する。 The effect will be explained.
共鳴室５は、内部に挿入した捩り板６によつ

して、短い共鳴室５で、低周波域の減衰ができ、
騒音の低減ができる。 The resonance chamber 5 becomes a spiral chamber by means of the torsion plate 6 inserted therein, and the length can be substantially increased, so that the noise in the low frequency range can be attenuated by resonance accordingly. Also, as shown in Fig. 3, the torsion plate 6 and the inner tube 7
By inserting this, it is possible to create a substantially long room by the torsion plate 6 and a short room by the inner tube 7, and it is possible to attenuate noise in the high frequency range in addition to the low frequency range. Furthermore, as shown in FIG. 4, if a communication hole 8 is provided in the inner tube 7, noise in the high and low frequency range can be caused to interfere through the communication hole 8, and further attenuation can be achieved. In this way, the short resonance chamber 5 can attenuate the low frequency range,
Noise can be reduced.

ので、小型のエンジンにも用いられる。 As explained above, in this invention, a resonance chamber is provided protruding from one side of the cleaner outer casing, and a torsion plate is inserted into the resonance chamber, so that the inside of the resonance chamber can be made into a spiral chamber by the torsion plate. This makes it possible to increase the actual length and attenuate noise in the low frequency range. Furthermore, when the torsion plate and the inner tube are combined, a substantially long chamber and a short chamber are created, and it is also possible to attenuate high and low frequency ranges. Furthermore, by providing a communication hole in the inner tube,
Interference can also occur. In this way, the resonance chamber with short external dimensions can attenuate noise in the low frequency range.
Since it can reduce intake noise and reduce external dimensions, it is also used in small engines.
