Abstract:
1. A control valve for a fluid circulation circuit, comprising a body ( 12 ) which is equipped with a fluid inlet ( 18 ) and with at least two fluid outlets ( 20 , 22 , 24 ) and which delimits a housing of revolution for an adjusting element ( 26 ) able to rotate about an axis of rotation (XX) and to adopt various angular positions to control the distribution of fluid through the outlets, the body ( 12 ) comprising an end wall ( 14 ) into which the fluid inlet opens and a side wall ( 16 ) into which the fluid outlets open, characterized in that the adjusting member ( 26 ) is surrounded by a sealing ring ( 42 ) in the form of an open annulus, which rotates as one with the adjusting member ( 26 ) and is arranged with a small clearance (j) around the adjusting member, this allowing the sealing ring to be pressed firmly internally against the side wall ( 16 ) with a view to ensuring sealing under the action of the pressure (P) of the fluid.
