Force transmitting arrangement for a valve drive of an internal combustion engine

Force transmitting device for a valve drive of an internal combustion engine with a hydraulic valve lash compensating device, with the force transmitting device having

• a hollow cylindrical compensating piston, which on one end defines a working chamber of the valve lash compensating device and on an other end encloses an internal hydraulic medium reservoir, which is used to supply the working chamber, which is connected to a hydraulic medium supply of the internal combustion engine, and which is protected from a return flow of hydraulic medium in a direction of the hydraulic medium supply by a valve plate that can be pressurized and that can move axially, the valve plate interacts in a sealing way with an axial annular surface of the compensating piston for a non-pressurized hydraulic medium supply to prevent the return flow from the internal hydraulic medium reservoir to the hydraulic medium supply, and includes one or more openings, which connect the internal hydraulic medium reservoir to an external hydraulic medium reservoir for a non-pressurized hydraulic medium supply, the valve plate is arranged between a base of a piston top part located on an end section of the compensating piston, and the annular surface of the compensating piston facing the base, and is enclosed on an outer peripheral surface via a sealing gap by an inner sleeve surface of the at least one of the compensating piston or the piston top part;
• wherein when the valve plate contacts the annular surface of the compensating piston, the outer peripheral surface of the valve plate which is tapered on a side facing the annular surface defines an annular space connected to the hydraulic medium supply, wherein the annular space is used for applying pressure to the valve plate in a direction of the base of the piston top part.
