The invention relates to a fluid circulation valve, notably for a motor vehicle, comprising a body (2) and a shutoff element (3) able, by rotation of said element (3) with respect to said body (2), to occupy various angular positions, said body (2) having a first (6), a second (7), a third (21) and
The invention relates to a fluid circulation valve, notably for a motor vehicle, comprising a body (2) and a shutoff element (3) able, by rotation of said element (3) with respect to said body (2), to occupy various angular positions, said body (2) having a first (6), a second (7), a third (21) and a fourth (22) inlet/outlet. Said valve is configured so that it: —in a first of said angular positions allows fluid to circulate from the first (6) to the second (7) inlet/outlet, —in a second of said angular positions allows fluid to circulate from the first (6) to the third (21) inlet/outlet, and from the fourth (22) to the second inlet/outlet (7), —in a third of said angular positions allows fluid to circulate from the first (6) to the fourth inlet/outlet (22) and from the third (21) to the second (7) inlet/outlet.

1. A fluid circulation valve for a motor vehicle, comprising: a body; anda sealing element able to occupy different angular positions by the rotation of said element relative to said body,said body having a first, a second, a third and a fourth inlet/outlet,said valve being 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, andin 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,wherein said first and second inlets/outlets are radial, and said third and fourth inlets/outlets are axial. 2. The valve as claimed in claim 1, wherein said sealing element has an angular path which is greater than 360° C. 3. The valve as claimed in claim 1, 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 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. 4. The valve as claimed in claim 1, wherein said third inlet/outlet is axially offset relative to said first inlet/outlet toward an axial end of said body. 5. The valve as claimed in claim 1, wherein said fourth inlet/outlet is axially offset relative to said second inlet/outlet toward an axial end of said body. 6. The valve as claimed in claim 1, wherein said third and fourth inlets/outlets are offset axially toward the opposing axial ends of said body. 7. The valve as claimed in claim 1, wherein said first and second inlets/outlets are of greater section than said third and fourth inlets/outlets. 8. The valve as claimed in claim 1, wherein said first and second inlets/outlets are an extension of one another. 9. The valve as claimed in claim 1, wherein said first and second inlets/outlets are of the same section. 10. A device for thermal conditioning of fluid comprising a valve as claimed in claim 1. 11. The device as claimed in claim 10, further comprising a heat exchanger connected between said third and said fourth inlets/outlets in the region of a so-called cooled line. 12. The device as claimed in claim 11, further comprising a non-cooled line, connected to said second inlet/outlet. 13. The device as claimed in claim 11, wherein one of said exchanger is configured so as to be a recirculated exhaust gas exchanger and said valve is configured so as to be a recirculated exhaust gas valve, orsaid exchanger is configured so as to be a charge air cooler and said valve is configured so as to be an air metering valve. 14. A fluid circulation valve for a motor vehicle, comprising: a body; anda sealing element able to occupy different angular positions by the rotation of said element relative to said body, whereinsaid 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, andsaid 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, andin 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.
