ABSTRACT:
A supercharged Diesel engine comprises a valve whose stem is slidably received in a valve guide, the end of the valve stem co-operating with actuating means located in a casing and lubricated by oil splash. At least one cavity is formed in the inner wall of the valve guide in close proximity to the end of the valve guide closest to the valve disk and communicates permanently with atmospheric pressure or a pressure close to atmospheric pressure. The cavity communicates with atmospheric pressure or with a pressure in the neighborhood of atmospheric pressure or by at least one axial passage formed on the outside of the valve guide and is permanently fed with lubricating oil.
