Abstract
A lever-type cam follower for a valve drive of an internal combustion engine for operating at least one gas exchange valve, includes a main body exhibiting a substantially U-shaped configuration and comprised of two spaced-apart side walls extending in a longitudinal direction and a cross member interconnecting the side walls. The cross member defines a valve-proximate side which includes a substantially planar bearing surface for receiving a gas exchange valve. In addition, the cross member is provided with a passageway for conduction of lubricant to a contact zone of the gas exchange valve upon the bearing surface, whereby the passageway is disposed outside the contact zone but in immediate proximity thereto.
