Abstract
Three-way valve with two flaps comprising single control means (9) for the two flaps and actuation means (12, 13, 50) arranged each to drive, pivotwise, one of the two flaps, from one to the other of its open and closed position of one of the pathways, with a temporal phase-shift, characterized in that it comprises maximum displacement end-stops for each of said actuation means, the end-stop (31) of the second actuation means (12, 50) corresponding to a fully closed position of its flap and the end-stop of the first actuation means (13) being positioned beyond the position of said first actuation means when the second actuation means (12, 50) is on its end-stop (31), the kinematic chains linking the first and second actuation means to the single control means operating nominally.
