Patent ID: 7302924

Claim:
Switchable drag lever ( 1 ) of a valve timing mechanism of an internal combustion engine, having an outer lever ( 2 ), an inner lever ( 5 ) extending with its arms ( 6 ) in the cut-out ( 3 ) of the said outer lever ( 2 ) between its side walls ( 4 ), a rest ( 9 ) for a gas exchange valve being intrinsic to the drag lever ( 1 ) on an underside ( 7 ) at one end ( 8 ), and a pivoting bearing ( 11 ) being intrinsic to the drag lever ( 1 ) at the other end ( 10 ), the levers ( 2 , 5 ) extending at one of the ends ( 8 , 10 ) on a common pin ( 12 ) and having receptacles ( 13 , 14 ) for at least one coupling means which extend longitudinally at the end ( 10 , 8 ) facing away from the pin ( 12 ) and are aligned with respect to one another in the cam base circle, which coupling means can be displaced for coupling the levers ( 2 , 5 ) in sections in or below the receptacle ( 14 , 13 ) which lies opposite, and at least one of the levers ( 2 , 5 ) being provided with a cam contact face ( 17 , 18 ) on its upper side ( 15 , 16 ), characterized in that a segment-like projection ( 19 ) protrudes longitudinally into the cut-out ( 3 ) from the outer lever ( 2 ) in the region of its end ( 10 ) which faces away from the pin ( 12 ), the bottom face ( 20 ) of the said segment-like projection ( 19 ) bearing against a complementary stop piece ( 21 ) of the adjacent upper side ( 16 ) of a pivoting-away end ( 22 ) of the inner lever ( 5 ) in the coupling case.
