A cam follower for actuating at least one gas exchange valve of an internal combustion engine is provided, including a cam contact roller that is supported by a plain bearing on a pin ( 13 ). A first sliding surface of the plain bearing faces the cam contact roller and a second sliding surface of the plain bearing faces the pin. The plain bearing has a lubricant reservoir, in order to provide at least one of the sliding surfaces of the plain bearing with lubricant, and the lubricant reservoir is arranged at a distance from the end sides of the plain bearing.
1. A cam follower for actuating at least one gas exchange valve of an internal combustion engine, comprising a cam contact roller that is supported by a plain bearing on a pin, the plain bearing includes a first sliding surface that faces the cam contact roller, a second sliding surface that faces the pin, and two end sides, and the plain bearing includes a lubricant reservoir formed by at least one surface channel extending partially into at least one of the sliding surfaces of the plain bearing in order to provide the at least one of the sliding surfaces of the plain bearing with lubricant, and the lubricant reservoir is arranged at a distance from the end sides.
2. The cam follower according to claim 1 , wherein the end sides and the lubricant reservoir are spaced apart from each other such that the cam follower forms a seal.
3. The cam follower according to claim 1 , wherein the at least one surface channel has a spiral-shaped construction.
4. The cam follower according to claim 1 , wherein the plain bearing is constructed as a slide ring.
