A separator for separating contaminants from a fluid stream comprises a chamber 20, a first inlet 6 for receiving a first fluid stream into the chamber including a convergent nozzle 18 for accelerating the first fluid stream, a second inlet 2 for receiving a second fluid stream including entrained contaminants into the chamber (20;58), the second inlet 2 being arranged relative to the first inlet 6 such that the first fluid stream can entrain and accelerate the second fluid stream forming a combined fluid stream within the chamber (20;58). The separator further comprises a surface (36, 50) coupled to the chamber (20;58) arranged such that the surface (36;50) can cause a deviation in the course of the combined fluid stream incident upon it such that contaminants are separated from the combined fluid stream. Advantageously the separator may be used instead of a filter to separate particulate, liquid and aerosol contaminants from blow-by gas stream in a reciprocating engine. |
