Abstract
An oil separator includes a casing 1 and a rotor 2, said rotor being arranged rotatably within said casing and having a flow chamber 3 through which oil-laden air 4 can pass, with porous material being arranged in the flow chamber 3. At least one unit of porous material is arranged in the flow chamber 3 which includes outer layers of a porous metal 6 and an interlaid layer 7 comprising fibre material.
Claims19
An oil separator, including:
- a casing,
- a rotor, said rotor being rotatably mounted within said casing and including a flow chamber through which oil-laden air can flow, and
- a porous material through which the oil-laden air can flow positioned in the flow chamber, the porous material comprising an outer layer comprising a porous metal and an inner layer comprising a fiber materials,
- wherein the layer comprising fiber material is enclosed by the porous metal at its axial sides and at its radially outer side.
