ABSTRACT:
A valve for crankcase ventilation of an internal combustion engine comprises a fresh-air side for connection with an intake section of the internal combustion engine, an engine side for connection with the crankcase and a valve insert movable as a whole for changing the flow resistance through the valve. Said valve inset is held inside said valve without pre-load. Said valve insert is designed to be freely displaced to a deventilation limit-stop position under negative pressure on the fresh-air side relative to the engine side, and to be freely displaced to a ventilation limit-stop position under excess pressure on the fresh-air side relative to the engine side. The valve insert is designed to open a deventilation cross-section in the deventilation limit-stop position and to open a deventilation cross-section that is different from the ventilation cross-section in the ventilation limit-stop position.
