Abstract:
A valve drive (1) for an internal combustion engine with a lever-type cam follower (7) is provided, which is used for the variable adjustable transmission of a raised section (2) of a cam (3) to a gas-exchange valve (5), in that the cam follower (7) is supported with an end section (13) away from the cam on a pivot bearing (14), which can be positioned variably on a circular arc-shaped displacement path (15), and an end section (6) close to the cam includes a transmission surface (10) in connection with the gas-exchange valve (5), and also with a support (8), wherein a contact surface (9) for the cam (3) is mounted rotatably on this support (8). Here, the center of the displacement path (15) should be essentially identical to the rotational center (17) of the support (8) when the contact surface (9) interacts with a raised section-free base circle (21) of the cam (3).
