There are two types though -

Atmospheric dumpvalves or BOVs are the ones that make the whoosh noise - alegedly cause fuelling problems but no-one on here has had any problems

Re-circulating valves 'dump' the air back into the intake so the same amount of air the MAF detected coming into the intake is circulating round the system.

MAF - Mass Air Flow (sensor) - tells the ECU how much fuel to supply to the engine

Some clever f*ckers have made them that re-circulate at low pressure and dump to atmosphere at higher pressures.

So that would make 3 types :)
