Claim:
An adjustable valve rocker lever ( 1 ) of a valve timing gear of an internal combustion engine, having an inner lever ( 3 ) and an outer lever ( 4 ) enclosing the former with its arms ( 2 ), the levers ( 3 , 4 ) running on a common axis ( 5 ) so that they can swivel relative to one another by way of coupling links ( 6 ) in such a way that a large valve lift is generated when coupled and a comparatively smaller or zero valve lift is generated when decoupled, the inner lever ( 3 ) on an underside ( 7 ) at one end ( 8 ) of the axis ( 5 ) having a seating face ( 9 ) for an exhaust and refill valve and at the other end ( 10 ) a complementary face ( 11 ) for a support element, and at least the outer lever ( 4 ) having a lifting face ( 12 ) for a lifting cam, and a lost-motion spring ( 13 ) being provided between the levers ( 3 , 4 ), wherein the axis ( 5 ), viewed in the longitudinal direction of the valve rocker lever ( 1 ), is arranged between the seating face ( 9 ) for the exhaust and refill valve and a section directly in front of the lifting face ( 12 ) for the lifting cam on the outer lever ( 4 ), the lost-motion spring ( 13 ), viewed in the axis ( 5 ), outside at the one end ( 8 ).
