    • PURPOSE:To prevent an exhaust valve from seizing and sticking, by using an air spring as a valve spring so that the exhaust valve is rotated by compressed air which is discharged from an air chamber upon opening of the valve. CONSTITUTION:A piston 100 having saw tooth-like blades 102 is disposed in the air chamber 15 of an air spring for urging an exhaust valve 12 in the closing direction of the latter, and nozzles 103 are formed in the lateral wall of the air chamber. When an engine piston 3 is pushed upward by a cam 1, the pressure in a piston chamber 9 is raised so that a valve rod 11 is depressed downward. When air in the air chamber 15 is compressed and the blades 102 are moved down to the level of the nozzles 103, the compressed air flows through a passage 101 around the blades 102, and is jetted from the nozzles 103 into an air sump 104. As the reaction of the stream of the compressed air, the blades 102 are exerted with torque which rotates the valve rod 11, resulting in the exhaust valve 12 being rotated little by little, thereby it is possible to prevent the exhaust valve from seizing and sticking.
    • 目的:通过使用空气弹簧作为阀弹簧来防止排气阀卡死,使得排气阀在打开阀门时从空气室排出的压缩空气旋转。 构成:具有锯齿状叶片102的活塞100设置在空气弹簧的空气室15中,用于沿排气阀12的关闭方向推压排气阀12,并且喷嘴103形成在气室的侧壁 。 当发动机活塞3被凸轮1向上推动时,活塞室9中的压力升高,使得阀杆11向下压。 当空气室15中的空气被压缩并且叶片102向下移动到喷嘴103的水平面时,压缩空气流过围绕叶片102的通道101,并且从喷嘴103喷射到空气槽104中。 作为压缩空气流的反应,叶片102施加有旋转阀杆11的扭矩,导致排气阀12一点一点地旋转,从而可以防止排气阀的卡住和粘附 。
