A method and device for taking up valve clearance in the valve mechanism (1) of an internal combustion engine, which mechanism includes rocker arms (4) arranged on at least one rocker arm shaft (5). The take-up occurs by means of an actively adjustable, hydraulically operated take-up means (6) operable between two positions, i.e. a withdrawn position and an extended position, which take-up means (6) is arranged at the operating end of the valves rocker arms whose valve clearance is to be taken-up. The hydraulic pressure for operating the take-up means is achieved by a somewhat increased lubrication pressure in the rocker arm shaft (5) for this type of engine, which pressure for said extension of the take-up means (6) is increased by wholly or partially blocking the oil's normal drainage. |
