VALVE TRAIN LEVER FOR A COMBUSTION ENGINE
The invention relates to a lever for a valve train for a combustion engine, comprising two parallel lateral walls (12, 13) with a gap (16) in between that are connected by a transverse bar (14). At the bottom side (18) of the transverse bar (14), a concave abutment (17) on a first end is provided as a contact point for a tappet rod, and at a second end a bearing surface (20) is provided as a contact point for a gas exchange valve. Each lateral wall (12, 13) has, in the region of the transversal mid-plane of the lever (11), a bearing ring for receiving a pivotal axis. According to the invention, the lever (11) is made of a material having a lower density compared to steel. However, the contact points of the abutment (17) and the bearing surface (20) and the bearing rings (15) are formed by steal parts (19, 21, 22) that are inserted into the lever material.
