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 ) whereby they can swivel relative to one another and being connectable to one another by way that a large valve lift is generated when coupled and a smaller or zero valve lift is generated when decoupled, the inner lever ( 3 ) on an underside ( 7 ) at one end ( 8 ) 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 the outer lever ( 4 ) on each arm having a lifting face ( 12 ) for a main lift cam and the inner lever ( 3 ) having a lifting face ( 13 ) for a low or zero-lift cam, and a lost-motion spring ( 14 ) 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 complementary face ( 11 ) for the support element and the lifting faces ( 12 , 13 ) for the lifting cams, the arms ( 2 ) of the outer lever ( 4 ) at one end ( 8 ) terminating in end faces ( 15 ) directly after their lifting faces ( 12 ) and the inner lever ( 3 ), at least with an area of its seating face ( 9 ) for the exhaust and refill valve, protruding lengthwise beyond the end faces ( 15 ) of arms ( 2 ) of the outer lever ( 4 ).
