<p>A connecting device for the pivotal and loss-prevention joining of an actuating lever ( 1 ) and a support element ( 6 ) of a valve operating mechanism of a combustion engine. The actuating lever ( 1 ) has, in a supporting section ( 3 ), a spherical cap-shaped cavity ( 5 ) inside of which the spherical end ( 7 ) of the supporting element ( 6 ) may be placed. A recess and/or undercut ( 8 ) is formed underneath the spherical end ( 7 ) in the supporting element ( 6 ). The actuating lever ( 1 ) has, in the supporting section ( 3 ), a spherical upper surface ( 4 ) above the spherical cap-shaped cavity ( 5 ). A securing element ( 9 ) joins the actuating lever ( 1 ) and the supporting element ( 6 ) to one another. This securing element ( 9 ) has a U-shaped cross-sectional shape with an upper and a lower limb ( 10, 11 ) that are joined to one another via a joining section ( 12 ). Geometrically closed openings ( 13, 14 ) for accommodating the recess ( 8 ) of the supporting element ( 6 ) or the spherical upper surface ( 4 ) of the supporting section ( 3 ) of the actuating lever ( 1 ) are made in both limbs ( 10, 11 ). The opening ( 13 ) in the upper limb ( 10 ) is essentially round, and the opening ( 14 ), which is located in the lower limb ( 11 ) while being assigned to the supporting element ( 6 ), is provided, in essence, in the form of a slot.</p> |
