Abstract
(EN) [Problem] To suppress the generation of fretting between an inner circumferential surface of a valve arm shaft insertion hole in a valve support and an outer circumferential surface of a valve arm shaft. [Solution] The present invention comprises a lubricating oil passage 14b and a valve arm support oil-pouring hole 14e in a valve arm shaft 14 that is penetrated by a valve arm shaft insertion hole 13a provided to a valve arm support 13. The valve arm support oil-pouring hole 14e opens toward the inner circumferential surface of the valve arm shaft insertion hole 13a in the valve arm support 13.
(FR) Le problème décrit par la présente invention est de supprimer la génération de frottement entre une surface circonférentielle interne d'un trou d'insertion d'arbre de bras de soupape dans un support de soupape et une surface circonférentielle externe d'un arbre de bras de soupape. La solution selon l'invention porte sur un passage d'huile de lubrification (14b) et sur un trou de remplissage d'huile de support de bras de soupape (14e) dans un arbre de bras de soupape (14) qui est pénétré par un trou d'insertion d'arbre de bras de soupape (13a) disposé sur un support de bras de soupape (13). Le trou de remplissage d'huile de support de bras de soupape (14e) s'ouvre vers la surface circonférentielle interne du trou d'insertion d'arbre de bras de soupape (13a) dans le support de bras de soupape (13).
(JA) 【課題】弁腕サポートの弁腕軸挿通孔の内周面と弁腕軸の外周面との間におけるフレッティングの発生を抑制する。 【解決手段】弁腕サポート13に設けられた弁腕軸挿通孔13aに挿通された弁腕軸14に潤滑油経路14bおよび弁腕サポート注油孔14eを備えさせる。弁腕サポート注油孔14eを、弁腕サポート13の弁腕軸挿通孔13aの内周面に向けて開口させる。
