Abstract (en)
[origin: WO2009115975A2] The invention concerns a valve assembly for the recirculation of the exhaust gases of an internal combustion engine, to an intake manifold of the engine, through a by-pass or respectively through a cooling device. The valve assembly comprises means for the deviation of an adjusted amount of exhaust gases, from a single inlet of exhaust gases (Gsc) to two outlets (13b, 14b), controlled by two distinct closing valves (13, 14), pushed by respective spring means (16). A single actuation means (21; 20, 36, 37; 42; 47; 20, 48, 49; 51) controls alternatively either one of said valves (13, 14), under the control of a single electric actuator (19, 25), controlled by an electronic central control unit, in association with a single position sensor (22, 30). The actuation means comprises a single rotary shaft (20, 43, 46, 52), whereon a rocker arm (21, 42, 47,51) is keyed, or a pair of cams (36,37; 48, 49) having angularly offset profiles, the two arms of the rocker arm, or the two cams, respectively, being apt to act on either one, respectively, of said valves.
