Abstract (en)

[origin: FR2782746A1] The invention concerns a control device (14) for an internal combustion engine turbocharger (16) unloading valve (42), comprising a pressure casing (58) wherein are arranged two front (92) and rear (93) transverse mobile walls, longitudinally defining front (104) and rear (106) pressure chambers capable of being subjected in particular to atmospheric pressure (Pa), excess pressure (Psur) or low pressure (Pdep) of an intake manifold (24) of the engine (12), wherein the front wall (92) co-operates with a longitudinal control rod (56) capable of taking up a retracted position and an extended position causing the valve (42) to open, and wherein the rear wall (94) co-operates with a second longitudinal rod (112). The invention is characterised in that the two rods are separate and the second longitudinal rod (112) can be urged forward from a retracted position to an extended position to be in contact with the front wall (92) to stress the latter towards its extended position.
