<p>The invention relates to a control valve (10) for a fluid circulation system, comprising a body (12). The aforementioned body, which is equipped with a fluid inlet (18) and at least two fluid outlets (20, 22, 24), defines a rotating housing for an adjustment element (26) which is designed to rotate around an axis of rotation (XX) and to occupy different angular positions in order to control the distribution of the fluid through the aforementioned outlets. The above-mentioned adjustment element (26) is surrounded by a seal ring (42) in the form of an open ring which is rotatably mounted to the adjustment element, such that a small clearance is disposed between said two elements. In this way, the seal ring can be pressed internally against a lateral wall (16), into which the fluid outlets (20, 22, 24) open, in order to provide sealing under the action of the pressure of the fluid. The invention is particularly suitable for motor vehicle fluid systems.</p> |
