Title:
VALVE OPERATION TRANSFER DEVICE OF INTERNAL-COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS6085205
Kind Code:
A
Abstract:
PURPOSE:To perform transfer of operation securely in a transfer device in which valve operation is transferred by moving a rocker arm in the rocker shaft direction by releasing a stopper which restricts movement through linking it with oscillating motions of the rocker arm. CONSTITUTION:A rocker arm 5 is arranged on a rocker shaft 2 movably in the axis direction and oscillating freely and it makes slidable contact with a cam for low speed 3 or a cam for high speed 4. A slider 9 is arranged in the rocker shaft 2 rockably and movably in the axis direction. And the slider 9 is connected to a frame 6, which moves in the axis direction by an actuator 7A which performs transfer, through springs 17 and 18. In case transfer force is applied to the slider 9 through a spring 17 or 18, the slifer 9 is oscillated by a pin 14 capable of coming in and out of a rocker arm 5. And when the rocker arm 5 makes contact with the base of the cam, engagement of a stopper 10 with the slider 9 is released, thereby transfer becomes possible.
