Abstract
A camshaft adjuster (10) for an internal combustion engine which includes a locking mechanism is provided. At least one locking element (21, 22) which can be locked in the zone of a central position (20) as well as at least one additional locking element (23, 24) that can be locked in the zone of a retarded end position (19) or an advanced end position (20) are provided such that the internal combustion engine can be selectively started from an end position (19, 20) or the central position.
Claims7
Camshaft adjuster for an internal combustion engine comprising
- a) a drive element and a driven element, which can be moved relative to each other with an adjustment movement of the camshaft adjuster,
- b) a locking device with a first locking element and a second locking element, each of which can be moved from an “unlocked position” into a “locked position,” in which the locking elements at least limit a relative movement between the drive element and the driven element
- c) the first locking element is in a region of an “advanced” end position and the second locking element is in a region of a “retarded” end position and both of the locking elements can be moved from the “unlocked position” into the “locked position.”
