Abstract
A control valve (10) for a fluid circulation circuit comprises a body (12) which is equipped with a fluid inlet (18) and at least two fluid outlets (20, 22 and 24) and which delimits a cylindrical housing for an adjusting member (26) able to rotate about an axis of rotation (XX) and to adopt various angular positions in order to control the distribution of fluid through the outlets. The body (12) comprises an end wall (14) into which the fluid inlet (18) opens and a cylindrical side wall (16) into which the fluid outlets open at axial heights and at angular positions that are chosen with respect to the axis of rotation (XX). The rotary member (26) comprises a truncated end (38) facing toward the end wall (14), this making it possible to have control over the fluid outlets using a law defined as a function of the angular position of the rotary member in the valve body.
