ABSTRACT:
A valve clearance compensator for an internal combustion engine. The compensator includes a sliding member provided with a wedge-shaped surface. The sliding members are arranged so as to be axially displaceable between each control cam of a camshaft and an associated valve. The sliding member is acted upon in one direction constantly by a compression spring but acted upon in the other direction intermittently by an adjusting member. The adjusting member is connected with the camshaft and is adapted to displace the sliding member against the force of the compression spring when the associated valve is in a closed position and over a partial range of a closed period of the valve.
