Anti-rattle valve, exhaust line comprising such valve and method for manufacturing such valve

A method for manufacturing a valve comprising

• a flap;
• a tubular valve body defining a passageway;
• and
• a guiding device that guides the flap relative to the tubular valve body for pivoting the flap relative to the tubular valve body about a pivot axis between a closed position and an open position of the passageway, the guiding device comprising a pin traversed by the pivot axis and comprising
• a body with a base and, opposite the base, a free end resting against the tubular valve body, and
• two lugs each protruding from the base in a direction opposite the free end, the two lugs defining a slot between the two lugs in which an edge of the flap is received, and
• at least one pressing member, connected to the flap, to press one of the two lugs of the pin against the flap, the method comprising the following steps:
• supplying the flap and the pin assembled to one another,
• supplying the at least one pressing member, the at least one pressing member comprising two tongues together defining a bearing plane of the at least one pressing member against the flap and having, between the two tongues, a recess having a maximal depth smaller than a thickness of at least one of the two lugs of the pin,
• positioning the at least one pressing member against the flap, the bearing plane bearing against the flap and the at least one of the two lugs being received in the recess, and
• welding the two tongues of the at least one pressing member to the flap.

A valve comprising:

• a flap;
• a tubular valve body defining a passageway;
• and
• a guiding device that guides the flap relative to the tubular valve body for pivoting the flap relative to the tubular valve body about a pivot axis between a closed position and an open position of the passageway, the guiding device comprising a pin traversed by the pivot axis, and wherein the pin comprises
• a pin body extending between a base end and a free end, the base end comprising two lugs defining a slot between the two lugs in which an edge of the flap is received, and
• wherein the two lugs directly engage the flap, and wherein the free end directly abuts against the tubular valve body, and
• at least one pressing member, connected to the flap, to press one of the two lugs of the pin body against the flap, and wherein the at least one pressing member includes a portion that bears directly against a face of the flap.
