Abstract
A drag lever for actuating a gas exchange valve of an internal combustion engine. The drag lever includes an oblong lever body formed of sheet metal material, wherein the lever body has a bottom and side walls integrally formed at an angle of about 90° onto the bottom on both sides. A first end section of the lever body includes a joint socket formed into the bottom between the side walls. The joint socket serves to pivotally moveably support the drag lever on a joint head mounted stationary in the internal combustion engine. A middle section of the lever body is provided with a cam gripping surface, and a second end section of the lever body has a contact surface extending on the bottom. The contact surface serves for actuating the gas exchange valve. The lever body is dimensioned so as to have essentially the same width in a cross section through the joint socket and in a cross section through the middle section. Starting from the first end section of the lever body, the angle of the side walls increases continually to about 90°.
