空洞型消音器の英語

密閉容器１１内に、発生騒音の特徴周波数に相当する共鳴周波数を有するヘルムホルツ型消音器の原理を適用して構成した、空洞部と開口部とを有する共鳴型の消音装置１４を配設する。例文帳に追加

In the closed vessel 11, a silencer 14 of resonance type is arranged which includes a cavity and an opening, constituted with the principle of Helmholtz type silencer having a resonance frequency corresponding to the characteristic frequency of generated noise being applied. - 特許庁

拡張室１２全体で挿入管空洞型消音器となるが、微細通路１８の個々で反射波の干渉による消音作用が生じるので、管長が異なることから、広い周波数帯域で減衰作用が得られ、はねかえりも小さくなる。例文帳に追加

The whole expansion chamber 12 forms an insertion pipe cavity type muffler, but since silencing operation due to interference of reflected waves at each of the fine passages 18 occurs, damping operation is obtained at a wide frequency band due to differences in a pipe length, and reflection is also decreased. - 特許庁

また、周波数の大きい音波が複雑な共鳴により効率よく減衰されるため、通常の共鳴型消音器に比べて、膨張空洞の長さを短くすることができる。例文帳に追加

Also, since the sonic wave with high frequency is efficiently attenuated by complicated resonance, the length of the expansion hollow can be shortened less than that of a normal resonance type muffling device. - 特許庁

一端部を閉塞させた円筒型とし、外周壁１６ｂに空気入口１８を設け、他端壁１６ａ中央部に空気出口１７を設けたケーシング１６の中央部に、軸心方向に延びて空気出口１７に連通する円筒状の消音器内空洞２２を設ける。例文帳に追加

At a central portion of a casing 16 formed into a cylindrical shape with one end closed and having an air inlet 18 provided in an outer peripheral wall 16b and an air outlet 17 in the center of an other end wall 16a, a cylindrical noise eliminator cavity 22 is provided which extends to the direction of the axial center and is communicated with the air outlet 17. - 特許庁
