Abstract:
1. Force-transmitting arrangement for a valve train of an internal-combustion engine comprising a hydraulic valve play compensation device with a hollow cylindrical compensation piston, which borders, on one end, a working space of the valve play compensation device and borders, on an other end, a hydraulic medium reservoir, which is used for supplying the working space and which is connected to a hydraulic medium supply of the internal-combustion engine, wherein a run-off safety device at least partially prevents a hydraulic medium flow from the hydraulic medium reservoir in a direction of the hydraulic medium supply, the hydraulic medium reservoir includes an inner storage space enclosed by the compensation piston and at least one outer storage space located outside of the compensation piston, wherein the run-off safety device extends between the hydraulic medium supply and hydraulic medium reservoir in a supply opening arranged in the force-transmitting arrangement, wherein the supply opening has in the supply direction a cross-sectional expansion facing the hydraulic medium reservoir with a shoulder, which is used as a seal seat for a sealing body of the run-off safety device.
