Abstract
The invention proposes a switchable finger lever ( ) comprising a fork-shaped outer lever ( ) between whose arms ( ) a fork-shaped inner lever ( ) is arranged for pivoting relative thereto. The outer lever ( ) comprises on an underside ( ) in the region of its one closed end ( ), a support ( ) for the gas exchange valve. The inner lever ( ) comprises on the underside ( ) on the opposite end ( ), a complementary surface ( ) for a support element, and on the side of the one end ( ), a cam contacting means ( ). The latter extends on an axle ( ) that is fixed in the outer lever ( ). The two levers ( ) can be coupled and uncoupled at the opposite end ( ) by a transversely displaceable coupling element ( ). In this way, a switchable finger lever ( ) is obtained that can also be designated as a “buckling” lever and, due to its configuration, has only a small design space requirement. At the same time, the finger lever ( ) has only a low mass moment of inertia and can be installed without complicated modifications in existing cylinder heads.
