【考案の詳細な説明】
本案はエンジン本体とそれに近接してエンジンにとりつ
けられる付属装置、部品との間に存する間隙に生起する
騒音を防止するための防音構造に関するものである。[Detailed Description of the Invention] The present invention relates to a soundproof structure for preventing noise generated in the gap between the engine body and accessory devices and parts attached to the engine in the vicinity thereof.
一般に、エンジン本体にはその周辺部に種々の付属装置
や付属部品が近接してとりつけられることが多いが、エ
ンジン本体とそれらの付属装置、部品との間に間隙が存
する場合には、その間隙にエンジンの作動時において定
在波による騒音が生起し、これによってエンジン全体の
騒音が増長される欠点があった。Generally, various attached devices and parts are often attached to the engine body in close proximity to its surroundings, but if there is a gap between the engine body and those attached devices or parts, that gap However, when the engine is operating, standing waves generate noise, which increases the overall noise of the engine.
本考案は上述の如き定在波による騒音起生を抑止するた
めにエンジン本体とそれに近接してエンジン本体にとり
つけられる付属装置、部品との間隙に緩衝材から戊る中
空と充てん物を充てんし、上記間隙より生ずる騒音を防
止するとともに、上記充てん物の充てん作業をより容易
に行わせようとするもので、以下その実施例を図につい
て説明する。In order to suppress noise caused by standing waves as described above, the present invention fills the gap between the engine body and the attached devices and parts that are attached to the engine body in close proximity with a hollow hole made from a cushioning material. This is intended to prevent the noise generated from the gap and to facilitate the filling operation with the filling material, and an embodiment thereof will be described below with reference to the drawings.
１はエンジン本体で、その上部には燃料噴射ポンプ２が
、側部には補機部品（例えばオルタネーター）３やオイ
ルフィルタ４等が夫々支持部材を介し、又は直接エンジ
ン本体１にとりつけられている。Reference numeral 1 denotes an engine body, on the top of which is a fuel injection pump 2, and on the sides of which auxiliary parts (for example, an alternator) 3, an oil filter 4, etc. are attached to the engine body 1 either through support members or directly. .
エンジン本体１とこれらの付属装置部品２，３．４等の
間には間隙Ｓｌ，Ｓ２，３３等が存在するが、これらの
間隙Ｓｌ，Ｓ２，Ｓ３に例えば発泡ウレタン、グラスウ
ール、カオウール、発泡ゴム等の変形容易な緩衝材から
戒り、且つ内部５ａを中空とした充てん物５を充てんし
たものである。Gaps Sl, S2, 33, etc. exist between the engine body 1 and these accessory parts 2, 3, 4, etc., and in these gaps Sl, S2, S3, for example, foamed urethane, glass wool, Kao wool, foamed rubber, etc. This material is made from easily deformable cushioning materials such as, etc., and is filled with a filling material 5 which has a hollow interior 5a.
尚、６，７は必要に応じて上記充てん物５を支持するた
めにエンジン本体１に溶接等により取付けたブラケット
である。Incidentally, reference numerals 6 and 7 indicate brackets attached to the engine body 1 by welding or the like in order to support the filling material 5 as required.
また、５ｂは上記充てん物５の一部を必要に応じて設け
る孔で、内部５ａを外気に通気させるためのものである
。Further, 5b is a hole provided in a part of the filling material 5 as necessary, and is for ventilating the inside 5a to outside air.
本案による充てん物５は以上のように中空体として構威
したものであるから、それをエンジン本体１と付属部品
２，３．４等との間の間隙Ｓ １，Ｓ ２，Ｓ３に充て
んする場合、上記間隙Ｓｌ，Ｓ２，Ｓ３の形状に応じて
極めて容易に変形し得るので充てん作業が簡単になると
共に、充てん後においては上記間隙Ｓｌ，Ｓ２，Ｓ３に
生ずる定在波の起生が抑止され、それによる騒音の発生
が防止される効果がある。Since the filling material 5 according to the present invention is configured as a hollow body as described above, it is filled into the gaps S1, S2, S3 between the engine body 1 and the attached parts 2, 3, 4, etc. In this case, the gaps Sl, S2, and S3 can be easily deformed according to their shapes, which simplifies the filling operation, and also suppresses the generation of standing waves that occur in the gaps Sl, S2, and S3 after filling. This has the effect of preventing the generation of noise caused by this.
また、第２図に示すように、充てん物５の一部に中空内
部５ａに通ずる孔５ｂを設けることによって、充てん物
５の挿入時の変形がより容易となると共に、外表面より
内部５ａへ浸み込んだ水滴等の排出が容易となる効果が
ある。In addition, as shown in FIG. 2, by providing a hole 5b in a part of the filling 5 that communicates with the hollow interior 5a, the filling 5 can be more easily deformed when inserted, and the filling can be inserted from the outer surface into the interior 5a. This has the effect of making it easier to drain soaked water droplets, etc.
尚、本考案の実施例においてはエンジン本体に近接され
る付属装置、部品として、燃料噴射ポンプ２、補機部品
３、オイルフィルタ４等を挙げたが、本考案はこれらの
一部の実施例に限定されるものではなく、他の種々のエ
ンジン付属装置、部品に広く応用され得るものである。In the embodiments of the present invention, the fuel injection pump 2, auxiliary parts 3, oil filter 4, etc. are listed as accessory devices and parts that are close to the engine body, but the present invention covers only some of these embodiments. The present invention is not limited to, but can be widely applied to various other engine accessories and parts.
また、吸音材の支持手段も本実施例のブラケット６，７
に限らず、他の種々の手段によっても行なうことができ
る。Further, the supporting means for the sound absorbing material is also the brackets 6 and 7 of this embodiment.
However, the present invention is not limited to this, and can also be carried out by various other means.
以上のように本考案はエンジン本体とそれに近接する付
属装置、部品との間隙に中空の緩衝材からなる充てん物
