Abstract
A camshaft adjuster which has a locking device by which a drive input and drive output part can be rotationally fixedly locked in a locking rotational position. The locking device has a multiplicity of engagement pairs which include one axial bar which is held in the drive input or drive output part and a bar slot which is formed in the respective other part. The engagement pairs are designed such that, during an adjustment of the drive output part in the drive direction, the bars can be placed in successive engagement with the bar slots in a relative rotational position between an end rotational position, which lags behind in the drive direction, and the locking rotational position. The bar slots prevent an adjustment of the drive output part counter to the drive direction and permit an adjustment in the drive direction until the locking rotational position is reached.
