Abstract:
A force-transmitting arrangement (4) for a valve train (1) of an internal-combustion engine (2) with hydraulic valve play compensation device (6) with a hollow cylindrical compensation piston (15) is provided. The compensation piston (15) borders, on one end, a working space (32) of the valve play compensation device (6) and, on the other end, a hydraulic medium reservoir (33), which is used for supplying the working space (32) and which is connected to a hydraulic medium supply (18) of the internal-combustion engine (2). A run-off safety device (22, 22a, 22b) at least partially prevents a hydraulic medium flow from the hydraulic medium reservoir (33) in the direction of the hydraulic medium supply (18). The hydraulic medium reservoir (33) includes an inner storage space (17) enclosed by the compensation piston (15) and at least one outer storage space (31) located outside the compensation piston (15), wherein the run-off safety device (22, 22a, 22b) extends between the hydraulic medium supply (18) and hydraulic medium reservoir (33) into a supply bore (35) arranged in the force-transmitting arrangement (4).
