Abstract (en)

An exhaust gas control valve (25) varies the exhaust gas flow rate flowing through two different courses (15,16) in an exhaust muffler of the semi-active type (1); the valve is provided with a shutter (39), which slides along a straight axis (28) in a guide seat (27) between a closed position, in which it is adjacent to an axial inlet (29) of the guide seat (27) and closes a valve seat (19), and an open position, in which it is distanced from such axial inlet (29) and leaves the valve seat (19) open; the shutter (39) is subject to the opposite actions defined by the pressure of the exhaust gases and by a spring (40) accommodated within the guide seat (27); the guide seat (27) is defined by a side wall (31) having at least one slot (35), through which the exhaust gases exit when the shutter is in open position.
