摘要： A camshaft is formed of an inner shaft (12), an outer tube (14) surrounding and rotatable relative to the inner shaft. Two groups of cam lobes (16, 18) are mounted on the outer tube. The cam lobes (16) of the first group being fast in rotation with the outer tube and the cam lobes (18) of the second group are rotatable relative to the outer tube (14) In the invention, one end of the camshaft (10) communicates with a cavity (31) in the engine to which a lubricant is supplied under pressure. The lubricant enters into the camshaft in an axial direction and serves to pressurise an annular passage between the inner shaft (12) and the outer tube (14) via which the lubricant is applied to the interface between the outer tube (14) and the cam lobes (18) of the second group.
