Patent ID: 7246584

Claim:
Force-transmitting arrangement ( 4 ) for a valve train ( 1 ) of an internal-combustion engine ( 2 ) comprising a hydraulic valve play compensation device ( 6 ) with a hollow cylindrical compensation piston ( 13 ), which borders, on one end, a working space ( 28 ) of the valve play compensation device ( 6 ) and borders, on another end, a hydraulic medium reservoir ( 29 ), which is used for supplying the working space ( 28 ) and which is connected to a hydraulic medium supply ( 23 ) of the internal-combustion engine ( 2 ), wherein a run-off safety device ( 27 ) at least partially prevents a hydraulic medium flow from the hydraulic medium reservoir ( 29 ) in a direction of the hydraulic medium supply ( 23 ), the hydraulic medium reservoir ( 29 ) includes an inner storage space ( 15 ) enclosed by the compensation piston ( 13 ) and at least one outer storage space ( 52 ) located outside of the compensation piston ( 13 ), wherein the run-off safety device ( 27 ) is arranged as a component of the force-transmitting arrangement ( 4 ) between the hydraulic medium supply ( 23 ) and hydraulic medium reservoir ( 29 ), wherein the run-off safety device ( 27 ) permits the hydraulic medium flow between a supply opening ( 25 ) arranged in the force-transmitting arrangement ( 4 ) and the hydraulic medium reservoir ( 29 ) in a supply direction (P) and blocks a flow in a direction opposite the supply direction (P) at least during a base circle phase of a cam ( 7 ) which activates the force-transmitting arrangement ( 4 ), and the run-off safety device ( 27 ) includes a slide ( 35 ), which can move relative to an inner casing surface ( 30 ) of a housing ( 9 ) of the force-transmitting arrangement ( 4 ) and which interacts with the inner casing surface ( 30 ) and with an outer casing surface ( 31 ) of an inner part ( 10 ) running within the housing ( 9 ), that faces the inner casing surface ( 30 ), to form a seal at least in a blocking position (L), blocking the hydraulic medium flow.
