ABSTRACT:
A hydraulic tappet-clearance compensating arrangement having no check valve includes an outer cylinder formed with a cup tappet and a piston axially displaceable in the outer cylinder and forming a pressure chamber therein. The outer cylinder is formed with a through-hole and a channel axially positioned so that a flow connection for the pressure medium is provided between the pressure chamber and a reservoir only during the base circle phase of the valve-operating cam and a flow connection is provided between the reservoir and a pressure medium supply only outside the base circle phase of the cam.
