Title (EN) CYLINDER HEAD
(FR) CULASSE
(JA) シリンダヘッド
Abstract:
(EN) A cylinder head (3) comprises: a cylinder head body (6) including an intake port (21) that is in communication with a cylinder (11) of a cylinder block (2), and a discharge port (22) that is in communication with said cylinder; and a rocker housing (7) integrally molded upon the cylinder head body, with the inner side of the rocker housing serving as a valve system accommodation space (40). The rocker housing includes: a side wall (41) including a side wall body (44), and a base end portion (45) that extends along the lower end of the side wall body, connects the side wall body to the cylinder head body, and is thicker than the side wall body. A flow passage (46) through which a fluid flows is formed within the base end portion, and extends in the extension direction of the base end portion.
(FR) Culasse (3) comprenant : un corps de culasse (6) comprenant un orifice d'admission (21) qui est en communication avec un cylindre (11) d'un bloc-cylindres (2), et un orifice de décharge (22) qui est en communication avec ledit cylindre ; et un boîtier de culbuteur (7) moulé d'un seul tenant sur le corps de culasse, le côté interne du boîtier de culbuteur servant d'espace de logement de système de soupape (40). Le boîtier de culbuteur comprend : une paroi latérale (41) comprenant un corps de paroi latérale (44), et une partie d'extrémité de base (45) qui s'étend le long de l'extrémité inférieure du corps de paroi latérale, relie le corps de paroi latérale au corps de culasse, et est plus épais que le corps de paroi latérale. Un passage d'écoulement (46) à travers lequel s'écoule un fluide est formé à l'intérieur de la partie d'extrémité de base, et s'étend dans la direction d'extension de la partie d'extrémité de base.
(JA) シリンダヘッド(3)は、シリンダブロック(2)の気筒(11)に連通する吸気ポート(21)、及び、気筒に連通する排気ポート(22)を有するシリンダヘッド本体(6)と、シリンダヘッド本体上に一体成形されているとともに、内側が動弁系収容空間(40)とされたロッカハウジング(7)と、を備える。ロッカハウジングは、側壁本体(44)、及び、側壁本体の下端に沿って延びて側壁本体をシリンダヘッド本体に接続するとともに側壁本体よりも厚さが厚い基端部(45)を有する側壁(41)を有する。基端部内には、基端部の延在方向に延びて流体が流通する流路(46)が形成されている。
