Abstract

An arrangement for adjusting the angle of rotation of a camshaft (5) relative to a crankshaft is provided. The arrangement requires many components, which partially also require different operational conditions. The new arrangement is structured in a modular fashion, so that the components of the arrangement are no longer arranged inside a common housing, but rather are separately constructed according to their function and/or operational conditions, for example, they are used jointly by other control or adjustment devices. It is particularly advantageous that such arrangements can be produced in a reduced size and in a more cost effective manner and can be used for adjusting the valve play of internal combustion engines.
