Abstract (en)

[origin: WO2004057160A1] Disclosed is an intermediate lever (1) for a variable valve drive of an internal combustion engine, comprising an impingement end and a pivoting end (2, 3), a cam stop area (4), and a support (5) for a return spring (6). The face of the impingement end (2) extends on the intermediate lever (1) and is provided with a sliding area (7) that comes in contact with a lever-type valve-opening device while the pivoting end (3) is designed so as to be able to communicate with eccentric means in order to modify the position of the intermediate lever (1). The cam stop area (4) is located between the impingement end and the pivoting end (2, 3). The inventive intermediate lever (1) is made of thin-walled sheet metal and is produced essentially in a stamping-bending process. The support (5) is located on a top face (8, 9) of the intermediate lever (1), in the edge region (10) towards the impingement end (2), while being provided with a convex extension which runs in the direction of the top face (8, 9) and comes in contact with a leg (11) of a torsion spring used as a return spring (6), and being laterally delimited by two guiding loops (12, 13).
