関の動弁装置。 The rocker arm is composed of a first arm rotatably attached to the rocker shaft, a second arm rotatably attached to the first arm by a fixed shaft extending parallel to the rocker shaft, and a second arm is rotatably attached to the rocker shaft. The ends of the two arms are engaged with the tops of the intake and exhaust valve stems, and between the first and second arms there is a hydraulic locking means having a piston and a spring-loaded locking pin that can be moved in and out in response to hydraulic pressure. A return spring is installed between the first arm and the second arm to urge the rocker arm to rotate so as to contact the cam, and an auxiliary return spring is installed between the first arm and a fixed part such as a cylinder head.
