Abstract:
1. A combined locking and rotational angle limiting device for locking and setting a maximum rotational adjustability of a drive input part, which is fixed with respect to a crankshaft, and a drive output part, which is rotatably adjustable relative to said drive input part and which is fixed with respect to a camshaft, of a camshaft adjuster for an internal combustion engine, comprising: a bar which is held in the drive output part and which is moved by a movement mechanism; a sealing element, which is formed in the drive input part and is arranged between a housing component and the drive output part, having a central bore with a bar slot and a rotational angle limiting slot each forming a radial recess of the bore, the bar slot holds the bar in a positively locking fashion in a circumferential direction, and the rotational angle limiting slot holds the bar in the circumferential direction, the rotational angle limiting slot has radial boundary wall sections, which are spaced apart in the circumferential direction, serving as stops for the bar in order to set a maximum rotational adjustability of both the drive input and the drive output part, and the bar slot, the rotational angle limiting slot and the bar are arranged in such a way that the bar is moved by the movement mechanism into a locked position, in which locked position said bar is guided by the bar slot, and the bar is moved by the movement mechanism into an unlocked position, in which unlocked position said bar is guided by the rotational angle limiting slot, wherein the bar is guided by the rotational angle limiting slot with an interposition of a sliding member engaging into the rotational angle limiting slot, and the bar is held in the sliding member so as to be movable in a bar movement direction.
