Title (EN) EXHAUST DIFFUSER
(FR) DIFFUSEUR D'ÉCHAPPEMENT
(JA) 排気ディフューザ
Abstract:
(EN) An exhaust diffuser is provided with an inner cylinder, an outer cylinder that together with the inner cylinder forms an exhaust passage widening rearward from the front, and at least one tubular strut linking the inner cylinder and the outer cylinder. The outer cylinder has a front conic section in front of the tubular strut, and an outer flare section that begins to widen in front of the tubular strut at a greater angle of inclination than the front conic section. The inner cylinder has a front strut section facing the front conic section and the outer flare section, and an inner flare section that begins to widen between the widest portion and the rear edge of the tubular strut.
(FR) La présente invention concerne un diffuseur d'échappement pourvu d'un cylindre interne, d'un cylindre externe qui, conjointement avec le cylindre interne, forme un passage d'échappement s'élargissant vers l'arrière depuis l'avant, et d'au moins une entretoise tubulaire reliant le cylindre interne et le cylindre externe. Le cylindre externe présente une section conique avant devant l'entretoise tubulaire, et une section évasée externe qui commence à s'élargir à l'avant de l'entretoise tubulaire au niveau d'un angle d'inclinaison supérieur à la section conique avant. Le cylindre interne présente une section d'entretoise avant faisant face à la section conique avant et à la section évasée externe, et une section évasée interne qui commence à s'élargir entre la partie la plus large et le bord arrière de l'entretoise tubulaire.
(JA) 排気ディフューザは、内筒と、内筒との間に、前方から後方に向かって広がる排気流路を形成する外筒と、内筒と外筒とを連結する少なくとも1つの管状ストラットと、を備え、外筒は、管状ストラットよりも前方に前側円錐部を有するとともに、前側円錐部よりも大きな傾斜角度で管状ストラットよりも前方から広がり始める外側フレア部を有しており、内筒は、前側円錐部および外側フレア部と対向する前側ストレート部を有するとともに、管状ストラットの最大幅部分と後縁の間から広がり始める内側フレア部を有している。
