Abstract (en)
[origin: US2004211400A1] A recycling circuit for crankcase gases from an internal combustion engine having an intake manifold with a throttling valve assembly and a cylinder head cover, in which a valve facilitates at least partial control of the flow of crankcase gases to be recirculated. The valve includes a spring and a diaphragm which divides the valve into two distinct chambers, one communicating with the atmosphere and the other communicating with the intake manifold, located downstream of the valve assembly, with a crankcase gas sampler, in which the chamber in communication with the manifold and with the crankcase gas sampler is integrated in the intake manifold and/or the cylinder head cover such that the membrane assures sealing of a part of the manifold or the cylinder head cover from the atmosphere.
