Patent ID: 8267059

Claim:
A switchable finger lever ( 1 ) for a valve train of an internal combustion engine, said finger lever ( 1 ) comprising an inner lever ( 2 ) comprising an underside ( 3 ) on one end ( 4 ), a support ( 5 ) for a gas exchange valve and on another end ( 6 ), a contact surface ( 7 ) for a head of a support element, said inner lever ( 2 ) comprising on the one end ( 4 ), outer arms ( 8 ) which are pivotable relative to the inner lever ( 2 ), which outer arms ( 8 ) extend in direction of the another end ( 6 ) while flanking outer walls ( 9 ) of the inner lever ( 2 ) and comprise on upper sides ( 10 ), contacting surfaces ( 11 ) for high lift cams, a coupling device ( 12 ) comprising a coupling slide ( 13 ) for simultaneously connecting the outer arms ( 8 ) to the inner lever ( 2 ) being seated in a section of the another end ( 6 ) in the inner lever ( 2 ), wherein the coupling slide ( 13 ) is seated in an oblong hole ( 14 ) extending transversely through the inner lever ( 2 ) as also in longitudinal direction of the finger lever ( 2 ), the coupling slide ( 13 ) comprises two end portions ( 15 ) which protrude beyond the outer walls ( 9 ), and for effecting coupling [high valve lift], the coupling slide ( 13 ) can be displaced with the two end portions ( 15 ) towards the one end ( 4 ) partially in or under entraining surfaces ( 16 ) of the outer arms ( 8 ) ending therein, whereas for effecting uncoupling, the coupling slide ( 13 ) can be displaced out of the entraining surfaces ( 16 ) towards the another end ( 6 ), and wherein at least one restoring spring ( 17 ) extends in a region of the another end ( 6 ) between the inner lever ( 2 ) and the outer arms ( 8 ).
