Patent ID: 8783219

Claim:
A switchable finger lever of a valve train of an internal combustion engine, said switchable finger lever comprising an inner lever and an outer lever, and further comprising on an underside on one end, a support for a gas exchange valve, and on a further end, a complementary surface for a support element, one of said two levers comprising on an upper side, a contacting surface for a high lift cam, and a further one of said two levers comprising a contacting surface for a low lift or zero lift cam, said two levers being connectable to each other through a coupling element and a common axle extending through bores therein for pivoting relative to each other, said common axle being surrounded by at least one coil assembly of a torsion leg spring as a cam re-setting spring, a first leg protruding from one front side of said coil assembly acting on a first chucking point of the outer lever in a twisting direction and a second leg protruding from a further front end of said coil assembly acting on a second chucking point of the inner lever in the twisting direction so that said levers are braced against each other, said common axle extending “floatingly” relative to said bores, said coil assembly surrounding with lash at least one bushing, and an axial fixing of said common axle being realized through an axis-offset segmental support of the coil assembly on the bushing in a braced state of the system and thus also through an axis-offset support of the bushing on the axle through a segmental part of an inner peripheral wall of said bushing, wherein, for reducing a resulting contacting force (F R ) in a region of the axis-offset support of the coil assembly on the bushing, the chucking points of the two legs of the coil assembly are positioned such that an angle (α) included by intersecting force vectors at the chucking points defined by an effective direction of two contact forces (F 1 , F 2 ) is in a range of 90°<α<180°.
