ABSTRACT:
A valve control device of the type having a rotating cam and a cam drive to communicate to a valve a reciprocating lifting movement in opposition to the closing force exerted by a return spring. The sliding surface of the cam drive comes in contact with the cam while immersed in an independent bath of lubricating oil having a high viscosity. Application is to a distribution device with reduced friction for internal combustion engines.
