An apparatus is described to separate oil from a gas in an internal combustion engine. The apparatus includes a rotatable member adapted to be rotatably driven by the internal combustion engine and a housing affixed to the rotatable member. At least one inlet hole is disposed through one of either the rotatable member or the housing, permitting oil-containing gas to pass therethrough. At least one outlet hole is disposed through one of either the housing or the rotatable member, permitting the gas to exit therefrom. At least one labrynthine passage extends between the at least one inlet and the at least one outlet so that, as the rotatable member and housing rotate, the oil-containing gas within the labrynthine passage is subjected to centrifugal forces. The forces cause at least some of the oil to be removed from the gas as the gas flows from the at least one inlet hole to the at least one outlet hole. A decompressor is also described.
