Abstract (en)
[origin: WO03004836A1] The invention relates to a recycling circuit for crankcase gases on an internal combustion engine, comprising an inlet collector with a throttling valve assembly and a rocker cover, in which a valve permits the at least partial control of the flow of crankcase gases for recycling. Said valve comprises a spring and a membrane which divides the valve into two distinct chambers, one communicating with the atmosphere and the other with the inlet collector, located downstream of the valve assembly, with a crankcase gas sampler, characterised in that the chamber in communication with the collector and with the crankcase gas sampler is integrated in the inlet collector and/or the rocker cover whereby said membrane guarantees the sealing of a part of the collector and/or the rocker cover from the atmosphere.
