Abstract: A device for separating oil droplets and/or oil mist from blow-by gases of an internal combustion engine having a valve for controlling the gas flow through the oil separator is disclosed. The valve has at least one valve body with at least one gas through-opening and also a valve seal for closing this at least one gas through-opening.

Abstract: A liquid separation device for the separation of liquid or liquid mist from a gas, with at least one pair of basic carriers being a first and a second plate-shaped basic carrier, where in each of the first and the second basic carrier, at least two separator elements are formed. The separator elements each have a passage pipe with a gas inlet and a gas outlet, which are arranged at opposite sides of the respective plate-shaped basic carrier in such a way that the passage pipe extends through the respective plate-shaped basic carrier. The first and the second basic carrier being arranged one next to the other in flow direction of the gas. Each of the two separator elements in both basic carriers in which the separator elements are arranged adjacent to each other, with their passage pipes form continuous flow paths for the gas.

Abstract: A device for separation of oil droplets and/or oil mist from blow-by gases of an internal combustion engine. Also described is a ventilation system for ventilation of the crankcase of an internal combustion engine, a cylinder head cover and an internal combustion engine, which contain such a device.
