Chain drive device for driving e.g. fuel high-pressure pump, of internal combustion engine, has control chain engaged in outer tooth system of sun wheel, and drive tooth wheel of aggregate acting together with inner tooth system of wheel
The device (1) has a chain drive (2) with a drive chain wheel (12) arranged at an end of a crank shaft in a torque proof manner. An output chain wheel (14) is attached to an aggregate e.g. cam shaft (4), and is connected with the drive chain wheel of the crank shaft in a form fit manner via a control chain (20). A drive tooth wheel for the aggregate is arranged on a drive shaft of the aggregate in a torque proof manner. The control chain is engaged in an outer tooth system of a sun wheel, and a drive tooth wheel of the aggregate acts together with an inner tooth system of the sun wheel.
