Abstract

A control time adjusting device which adjusts the phase position of a camshaft with respect to an upstream drivetrain that drives the camshaft. The device has a hub element and a bell element which is coupled to the hub element in a variably adjustable manner with regard to the rotary phase position. The adjusting angle range is defined by stop structures. Additionally, adjusting cells, which are separated by radial webs and vane elements, are situated in an intermediate space between the hub element and bell element. The position and the peripheral length of the device, which is definitive for the pivoting travel of the adjusting cells and the arrangement of the vane elements with respect to one another, are adapted such that at least two different-sized adjusting angle ranges can be defined as a function of the assignment of the vane elements to the adjusting cells.
