Line) orthogonal perspective plane observation when, linking the imaginary line of the pivot center and the contact start point x, (i.e. follower F is from driving
The arm for the torque that portion D is subject to) relative to the rotation axis comprising two valves V1, V2 imaginary plane f and (i.e. to the sides driving portion D
The sides solar term valve shaft j1) topple over.
Thereby, it is possible to inhibit follower F highlightedly longer to the direction for leaving the imaginary plane f, and can will be upper
Stating the effective length of the arm of torque ensures enough to length, thus can either avoid linkage mechanism M in this direction protrusion and realize
The miniaturization of linkage mechanism M, and the contact point loading of driving portion D and follower F can be reduced and effectively inhibit the mill of contact site
Damage.Moreover, air throttle V1 and surplus valve V2 are configured as under their full-gear along intake channel I (air intake duct 2)
