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. ## Claims ### Claim 1 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, 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, 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, wherein said first and second inlets/outlets are radial, and said third and fourth inlets/outlets are axial. ### Claim 2 (depends on 1) The valve as claimed in claim 1, wherein said sealing element has an angular path which is greater than 360° C. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 1) 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. ### Claim 5 (depends on 1) 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. ### Claim 6 (depends on 1) 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. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 1) The valve as claimed in claim 1, wherein said first and second inlets/outlets are an extension of one another. ### Claim 9 (depends on 1) The valve as claimed in claim 1, wherein said first and second inlets/outlets are of the same section. ### Claim 10 (depends on 1) A device for thermal conditioning of fluid comprising a valve as claimed in claim 1. ### Claim 11 (depends on 10) 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. ### Claim 12 (depends on 11) The device as claimed in claim 11, further comprising a non-cooled line, connected to said second inlet/outlet. ### Claim 13 (depends on 11) 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, or said exchanger is configured so as to be a charge air cooler and said valve is configured so as to be an air metering valve. ### Claim 14 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.
