Claim:
An intake manifold with integrated canister circuit for a supercharged internal combustion engine provided with a compressor adapted to compress the intake air; the intake manifold comprises: a tubular body in which a plenum is defined, which has an inlet opening connected to an intake pipe along which the compressor is arranged and a number of outlet openings towards the cylinders of the internal combustion engine; a sorting chamber, which is obtained in a wall of the tubular body and has an open upper end; a canister solenoid valve, which is arranged in the sorting chamber to close the open upper end and is adapted to adjust the introduction of gasoline vapours coming from a fuel tank inside the sorting chamber itself; a first pipe, which is obtained in the wall of the tubular body, puts the sorting chamber into communication with the plenum, and defines a first branch of a recovery pipe; a one-way membrane valve, which is arranged in the sorting chamber at the first pipe to allow only a flow towards the plenum through the first pipe itself; and a second pipe, which is obtained in the wall of the tubular body, puts the sorting chamber into communication with the intake pipe upstream of the compressor, and defines an initial portion of a second branch of the recovery pipe.
