Abstract
The invention relates to a rocker arm (1) of a valve train of an internal combustion engine. This rocker arm (1) comprises two longitudinally extending side walls (2, 3) which enclose an intermediate space (16) while being connected to each other by a crossbeam (4) to form a U-shaped cross-section. According to the invention, a separate channel (24) for the transport of lubricant is created on a top surface (22) of the crossbeam (4). This channel (24) starts from an abutment (9) for an end of a push rod on the undersurface (8) of the crossbeam (4) and leads to a support (12) for an end of a gas exchange valve in the region of a second end (11) of the crossbeam (4).
