  • Hydraulic valve-play compensation element
    Patent number: 6318325
    Abstract: The invention relates to a hydraulic valve-play compensation element. The aim is to prevent any change in the length from taking place when the engine is at a standstill. To this end, the leakage oil is guided into the space between the high pressure valve (4) and the valve (5), where it then reinforces the sealing effect of valve (5). When the engine is in operation, the valve (4) is kept open irrespective of the direction of throughflow by means for producing a defined force, for example, a pressure-loaded piston or by electromagnetic means.
