Device for regulating lubricating oil pressure includes control valve mechanism where different active faces of one or more work pistons are impinged dependent on pressure level to be set

摘要

The device includes a control valve mechanism (36) where dependent on a pressure level which is to be set different active faces (22, 32) of one or more work pistons (22', 32') of the control valve mechanism can be impinged. the control valve mechanism comprises at least two parallel connected control valves (20,30). Independent claim describes method for regulating pressure of engine oil by impinging on different active faces of one or more work pistons dependent on the pressure level to be set. A control line (28) can be released or closed depending on this pressure level.
