<p>An exhaust braking valve, for use with an internal combustion engine having a divided exhaust manifold and a turbocharger having a turbine wheel to which two separate gas flows can be led from said divided manifold, is constructed such that, in a non exhaust braking condition, free but separate flow of the two gas paths from the divided manifold to the turbine wheel is provided but, in an exhaust braking condition, gas flow to the turbine wheel is cut off by a closure member (19) of the valve and an interconnection between the two gas paths is provided at a location upstream of the closure member (19). The interconnection of the upstream portions of the flow paths, viz 14a, 14b, may be effected by means of recesses 28, 30 provided in the valve rotor 20 and/or in the valve housing. In the modification the valve closure is a sliding gate. <IMAGE></p> |
