The invention relates to a cylinder head oil separator arranged in a cylinder head of an internal combustion engine. In order to reduce maintenance and simplify the oil separator, the cylinder head oil separator includes a flow channel which is constructed as a Tesla valve and which is designed such that the air-oil aerosol flows through a longer flow path in a first flow direction from the aerosol inlet at a first opening to the air outlet (separation direction) at a second opening. The air-oil aerosol flows through a shorter flow path in a ventilation direction opposite the separation direction from the inlet at the second opening to the outlet of a fluid at the first opening.
A cylinder head oil separator which is arranged in a cylinder head of an internal combustion engine, wherein the internal combustion engine accommodates in an engine block in relatively moveable relationship at least one piston which with a piston lower end drives a crankshaft mounted rotatably in a crankcase, wherein there is provided a sump arranged beneath the crankshaft for collecting an oil, wherein the cylinder head oil separator has a first opening for the feed of an air-oil aerosol fed by way of a feed line from the crankcase, an oil separation apparatus fluidically connected thereto for separation of the oil from the air-oil aerosol and a fluidically connected second opening which adjoins the oil separation apparatus and which can be connected in flow relationship to a return line for return of an air cleaned of the oil, wherein the oil separation apparatus includes a flow passage configured in the form of a Tesla flow valve, such that an air-oil aerosol entering at the first opening in a separation direction (SR1) to an air outlet of the air cleaned of the oil at a second opening flows through a longer flow path than a fluid which enters at the second opening and which flows to the first opening in a venting direction (SR2) in opposite relationship to the separation direction and the flow passage is of such a geometrical configuration in the separation direction (SR1) in order to implement flow-controlled oil separation.
