Abstract: This invention consists of an air cylinder that encompasses the upper portion of each valve stem and guide on an internal combustion engine. The air cylinders are provided with annular pistons. The upper end of each valve stem is provided with a dish-shaped washer that will rest on the top of a piston when the valve is open and will be forced upward by the top of the piston by the air in the cylinder to urge the valve toward its closed position.

Abstract: An internal combustion engine is provided with an exhaust valve which has a tapered plug part, a tube-shaped member which is arranged in a region where the exhaust valve is arranged and which is engaged with the tapered plug part of the exhaust valve at one end part which faces a combustion chamber, and a fluid spring for biasing the tube-shaped member to the side facing the combustion chamber. The tube-shaped member is formed so as to be able to move substantially parallel to the direction of movement of the exhaust valve and the other part abuts against the fluid spring. The fluid spring is formed so as to contract using the change in pressure of the combustion chamber as a drive source when the pressure of the combustion chamber reaches a predetermined control pressure.
Abstract translation: 一种内燃机设置有具有锥形塞部的排气阀，配置在排气阀配置的区域的管状部件，其一端与排气阀的锥形塞部配合 面向燃烧室的部分，以及用于将管状部件偏置到面向燃烧室的一侧的流体弹簧。 管状部件形成为能够大致平行于排气阀的移动方向移动，另一部分抵靠流体弹簧。 当燃烧室的压力达到预定的控制压力时，流体弹簧形成为使用燃烧室的压力变化作为驱动源来收缩。

Abstract: A large two-stroke diesel engine with an electronically controlled exhaust valve actuation system includes for each cylinder an exhaust valve with a valve stem and a valve disc, an air spring operably connected to the valve stem and urging the exhaust valve towards the closed position, a hydraulic actuator operably connected to the exhaust valve, an electronically controlled hydraulic system that selectively connects the hydraulic actuator to a source of high pressure hydraulic fluid for a first short period at the start of the opening stroke of the exhaust valve, and an intermediate pressure hydraulic accumulator for a period immediately following the first short period until the exhaust valve has reached it open position, the intermediate pressure hydraulic accumulator from the start of the closing stroke of the exhaust valve until the start of a last short period at the end of the closing stroke of the exhaust valve, and to tank during the last short period of the closing stroke of the exhaust valve.

Abstract: エンジンはクランクシャフトを有している。 圧縮ピストンは圧縮シリンダー内に収容され、作用的にクランクシャフトに連結されている。 クロスオーバー通路が圧縮シリンダーと膨張シリンダーを相互に連結している。 クロスオーバー通路は、間に圧力チャンバーを画成するクロスオーバー圧縮（XovrC）バルブ及びクロスオーバー膨張(XovrE)バルブを含んでいる。 クロスオーバー圧縮バルブは、クロスオーバー圧縮バルブにおいて圧縮シリンダーの圧力がクロスオーバー通路の上流圧力より低いときに開くようにタイミング付けられている。
