Abstract Translated from Japanese (57)【要約】 【目的】 内燃機関の動弁装置において、その弁作動切 換機構の切換作動時に、少なくとも吸気弁あるいは排気 弁の開弁リフト量が大である状態では切換機構の切換ピ ンが対応するカムフォロアのガイド穴より抜けないよう にする。 【構成】 第1及び第2切換ピンは、油圧室への油圧作 用に応じて切換作動する際に、自由カムフォロアおよび 第2駆動カムフォロアに同時あるいは第2切換ピンが先 行して嵌合するように構成される。 (57) [Abstract] [Purpose] In a valve train of an internal combustion engine, at the time of switching operation of the valve operation switching mechanism, the switching pin of the switching mechanism operates at least when the valve opening lift of the intake valve or the exhaust valve is large. Make sure it does not come out of the guide hole of the corresponding cam follower. [Structure] The first and second switching pins are adapted to engage with the free cam follower and the second drive cam follower at the same time or in advance of the second switching pin when the switching operation is performed in response to the hydraulic action on the hydraulic chamber.
