Joining device for an actuating lever and supporting element of a valve operating mechanism of an internal combustion engine

A connection device for a pivotable and captive connection of a control lever (1) and an associated support element (6) of a valve controller of an internal combustion engine comprising

• a supporting section (3);
• a calotte shaped recess (5) disposed in the supporting section (3);
• a support element (6) being located in the calotte shaped recess (5);
• a spherical end (7) of the support element (6) being located in said recess (5);
• an undercut (8) is provided below the spherical end (7) of the support element (6);
• a spherical top side (4) disposed in the supporting section (3) above the calotte-shaped recess (5),
• wherein the spherical top side (4), and the supporting section (3) form a control lever (1);
• an upper leg (10);
• a lower leg (11);
• a connecting section (12) connecting the upper leg (10) to the lower leg (11);
• an upper geometrically closed opening (13) is furnished in the upper leg (10) to receive the spherical upper side (4) of the supporting section (3) of the control lever (1);
• a lower geometrically closed opening (14) is furnished in the lower leg (11) to receive the undercut (8) of the support element (6);
• wherein the upper opening (13) in the upper leg (10) is essentially round and wherein the lower opening (14) in the lower leg (11), is associated with the support element (6), and is essentially slot-shaped, and wherein the upper leg (10), the lower leg (11), the connection section (12) form a retaining element (9), wherein the retaining element (9) exhibits a U-shaped cross-sectional geometrical form, and wherein the retaining element (9) connects the control lever (1) and the support element (6).
