摘要:
A valve control arrangement for an internal combustion engine with reciprocating pistons, comprises a combustion chamber valve, a driving cam of the combustion chamber valve, a movement transmission group arranged between the combustion chamber valve and the driving cam and having a pressure chamber which is fillable with a pressure medium and unloadable from the pressure medium, an unloading conduit through which the pressure chamber is unloaded, and electrically controlled blocking valve arranged in the unloading conduit for blocking and releasing the unloading conduit and therefore coupling or uncoupling the combustion chamber valve relative to the driving cam, the blocking valve being formed as electromagnetically controlled 2/2 directional control valve.
