Claims (6)
上記ダンパの回転に伴うポンプ作用によって上記カバー内の空間に空気を導くための空気入口と上記空間から空気を排出するための空気出口とが上記カバーに設けられており、
上記空気入口と上記空気出口とは、クランクシャフトの軸方向に互いにオフセットしており、
上記空気出口は、オフセットして位置する上記空気入口から流入した空気が３６０°旋回してから排出されるように、上記空気入口の周方向下流側に隣接して配置されている、
内燃機関のダンパ冷却構造。 In an internal combustion engine, a disc-shaped damper is attached to a rotating shaft protruding from an end face of the engine body, and a cover is provided to cover the damper.
The cover is provided with an air inlet for guiding air into the space within the cover by a pumping action accompanying rotation of the damper, and an air outlet for discharging air from the space,
The air inlet and the air outlet are offset from each other in the axial direction of the crankshaft,
The air outlet is disposed adjacent to the downstream side of the air inlet in the circumferential direction so that the air flowing in from the air inlet located offset therefrom turns 360 degrees and is then discharged.
