Abstract

Improvements in hydraulic actuation systems for periodically moved elements, in particular internal combustion engine exhaust valves, of the type comprising, a hydraulic cylinder for moving said element against an elastic restoring force, the cylinder communicating with a hydraulic actuating cylinder having a piston moved by a cam disc, supplying fluid under overpressure through a plurality of conduits, characterized in that the supply conduits comprise at least one conduit that has an inwardly facing non-return valve, and which is going to give the interior of the system, at a point within the innermost position of the actuation piston, and at least one conduit controlled by the actuation cylinder, which ends in a non-return valve in the actuation cylinder around the point position dead outermost of the corresponding piston.
