Patent ID: 7240652

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