Abstract:
(EN) An exhaust muffler comprising first and second pipes which penetrate through a casing or a partition wall partitioning the inside of the casing into a plurality of expansion chambers, and which are arranged with a downstream end of the first pipe coaxially facing an upstream end of the second pipe, wherein: the downstream end (55a) of the first pipe (55) and the upstream end (57a) of the second pipe (57) are spaced apart from each other in an axial direction; one end of a support member (75) having a circular cross section and having a diameter smaller than those of the first and second pipes (55, 57) is fixed to one of a first cover member (63) covering an opening part of the downstream end (55a) of the first pipe (55) and a second cover member (72) covering an opening part of the upstream end (57a) of the second pipe (57); and the other end of the support member (75) is slidably fitted into the other of the first and second cover members (63, 72). Thus, in connecting and supporting a pair of pipes with respect to one another, a restriction in the lengths of the pipes is less liable to arise, thus increasing the degree of freedom in design.
(FR) La présente invention concerne un silencieux d'échappement comprenant des premier et second tuyaux qui pénètrent à travers un boîtier ou une paroi de séparation divisant l'intérieur du boîtier en une pluralité de chambres d'expansion, et qui sont agencés avec une extrémité aval du premier tuyau faisant face de manière coaxiale à une extrémité amont du second tuyau, l'extrémité aval (55a) du premier tuyau (55) et l'extrémité amont (57a) du second tuyau (57) sont espacées l'une de l'autre dans une direction axiale; une extrémité d'un élément de support (75) ayant une section transversale circulaire et ayant un diamètre plus petit que ceux des premier et second tuyaux (55, 57) est fixée à l'un parmi un premier élément de couvercle (63) recouvrant une partie d'ouverture de l'extrémité aval (55a) du premier tuyau (55) et un second élément de couvercle (72) recouvrant une partie d'ouverture de l'extrémité amont (57a) du second tuyau (57); et l'autre extrémité de l'élément de support (75) est ajustée de manière coulissante dans l'autre des premier et second éléments de couvercle (63, 72). Ainsi, lors de la connexion et du support d'une paire de tuyaux l'un par rapport à l'autre, une restriction dans les longueurs des tuyaux est moins susceptible de se produire, ce qui permet d'augmenter le degré de liberté de conception.
(JA) ケーシングならびにケーシング内を複数の膨張室に区画する隔壁のいずれかを貫通する第1および第2パイプが第1パイプの下流端部を第2パイプの上流端部に同軸に臨ませて配置される排気マフラーにおいて、第1パイプ(55)の下流端部(55a)および第2パイプ(57)の上流端部(57a)が軸方向に相互に離間して配置され、第1パイプ(55)の下流端部(55a)の開口部を覆う第1蓋部材(63)ならびに第2パイプ(57)の上流端部(57a)の開口部を覆う第2蓋部材(72)の一方に、第1および第2パイプ(55,57)よりも小径である横断面円形の支持部材(75)の一端部が固定され、支持部材(75)の他端部が、第1および第2蓋部材(63,72)の他方にスライド可能に嵌合される。これにより、一対のパイプ同士の接続支持を行なうにあたって、パイプの管長に制約を受け難くして設計の自由度を高めることができる。
