Claim:
An assembly comprising: a valve body; a seal; and a pipe, the valve body comprising a gas flow passage and a valve shutter mobile between an open position and a closed position, the closed position obstructing movement of the gases in the passage, wherein the passage is configured to be connected to the pipe to enable flow of gas between the passage and the pipe, wherein the seal is mounted between the passage and the pipe to provide a gas seal between the passage and the pipe, wherein the seal forms a seat for the valve shutter in the closed position, and wherein the assembly forms a “three-port” valve of an automobile vehicle internal combustion engine, wherein the pipe is an exhaust pipe providing an inlet passage for gases entering the valve and a passage for direct exhaust of gases leaving the valve, and wherein the passage forms a recirculation passage for recirculating the exhaust gases toward a heat exchanger and is connected to the pipe at an orifice formed on a wall of the latter.
