Fluid circulation valve, notably for a motor vehicle, and thermal conditioning device comprising such a valve

A fluid circulation valve for a motor vehicle, comprising:

• a body;
• and
• a sealing element able to occupy different angular positions by the rotation of said element relative to said body, wherein
• said body comprises an internal cylindrical housing of circular cross section, and said sealing element comprises at least one sealing part arranged in a plane which is inclined relative to said internal cylindrical housing and cooperating with the lateral wall of said housing by a peripheral generatrix, so as to ensure sealed contact between the sealing element and the body in at least one angular position,
• said body has a first, a second, a third and a fourth inlet/outlet, and
• said valve is configured so as to permit:
• in a first of said angular positions, the circulation of the fluid from the first to the second inlet/outlet,
• in a second of said angular positions, the circulation of the fluid from the first to the third inlet/outlet and from the fourth to the second inlet/outlet, and
• in a third of said angular positions, the circulation of the fluid from the first to the fourth inlet/outlet and from the third to the second inlet/outlet.
