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 ventilation system for the ventilation and for the aeration of an internal combustion engine is described. The ventilation system for the aeration and for the ventilation of an internal combustion engine has an intake pipe and a supercharger arranged in the intake pipe, an air-oil separator for the separation of oil and/or oil mist from blow-by gases with at least one inlet and at least one outlet, an intake pipe for blow-by gases connected to at least one of the inlets of the air-oil separator, a first tube for the connection of the at least one outlet of the air-oil separator with the intake section of the internal combustion engine ahead of the supercharger, and a second tube for the connection of the at least one outlet of the air-oil separator with the intake section of the internal combustion engine behind the supercharger.

Abstract: The invention relates to a valve for controlling a gas flow, as it is used, for example, for controlling the gas flow between a crankcase and an intake tract of an internal combustion engine. The invention further relates to a liquid separator and to a ventilation system for the above-mentioned exemplary use for a crankcase and to an internal combustion engine.

Abstract: The invention relates to a cover assembly for covering of a cylinder head with a lid, a frame and at least one air-oil separator, as well as the use of such a cover assembly as an enclosure for at least one cylinder head of a combustion engine of a vehicle or a combustion engine for stationary use.
