Abstract (en)

[origin: FR2777945A1] The retarder, mounted in a vehicle IC engine exhaust circuit, has at least one valve (2) with its shutter controlled by a power cylinder (9), and has a balancer (25) for the counter pressure applied to the exhaust gases by the shutter. The balancer is incorporated in the control cylinder and is situated between two separate coaxial sections of its piston rod (12). One section of the rod is able to perform a set stroke relative to the other, the length of the stroke corresponding to the degree of re-opening of the shutter before the counter-pressure reaches a set threshold level and controlled by a calibrated spring (26).
