VALVE DRIVE APPARATUS AND SUPERCHARGER HAVING THE SAME

摘要

The present invention relates to a valve driving device which drives a first valve (17) and a second valve (18) of a supercharger. One end portion of a first rod (71) is rotatably connected to a first valve lever shaft (612), and the other end portion of the first rod (71) is connected to a shaft (35) such that the first rod (71) drives the first valve (17); and one end portion of a second rod (72) is rotatably connected to a second valve lever shaft (622) and the other end portion of the second rod (72) is connected to a second member (50) such that the second rod (72) drives the second valve (18). A spring (81) is arranged between a first coupling portion (412) of a first member (40) and a second coupling portion (531) of the second member (50). The first member (40) and the second member (50) are pressed such that a first contact portion (411) of the first member (40) and a second contact portion (511) of the second member (50) are pressed towards each other.
