ABSTRACT:
The invention relates to a device for lubricating the guiding system of an internal combustion engine valve having at least one valve stem mounted in a guide. A first upper cavity communicates permanently with a second lower annular cavity through a conduit. The first cavity is selectively interconnected to a lubricant intake duct through a sliding valve comprising an annular groove on the valve stem. A third cavity between the intake duct and the slide valve provides lubrication of the upper portion of the valve guide.
