1. A dispensing device for a drink based on a first fluid to which a second fluid can be added selectively, said device comprising: a support containing a dispensing chamber having a first port communicating with a reservoir of said first fluid, a second port communicating with a reservoir of said second fluid, and an outlet port for said first and/or second fluids, anda dispensing assembly mounted movably relative to said support following: a first displacement arranged to open and close said outlet port and/or the first port selectively, said device including a first actuating element for said first displacement, anda second displacement arranged to open and close said second port selectively, said device comprising a second actuating element to enable the actuation of said second displacement;the second actuating element being arranged to be actuated, after the actuation of the first element and following a type of motion which is different to the motion necessary to actuate said first element, the support having a first fluid passage for the first fluid, the dispensing assembly including an end piece in which the dispensing chamber is formed, said end piece being movable relative to said passage following the first displacement so as to selectively open and close the communication between the first port and said first fluid passage, and further including an insert in which a second fluid passage is formed for the second fluid, the end piece being movable relative to said insert following the second displacement so as to selectively open and close the communication between said second port and said second fluid passage. 2. The dispensing device according to claim 1, the first and second actuating elements being arranged to drive the dispensing assembly successively after the first and second displacements of the dispensing assembly. 3. The dispensing device according to claim 2, one of the first or the second actuating element being movable in rotation to drive the dispensing assembly after one of the first or second displacement of the dispensing assembly. 4. The dispensing device according to claim 1, the dispensing assembly being mounted movably in relation to the support following a third displacement, which is arranged to control the size of the opening of the second port. 5. The device according to claim 1, the end piece including a non-return valve arranged to close the communication between the first port and the passage of the first fluid. 6. The dispensing device according to claim 1, the end piece being moveable following the second displacement so as to open and close selectively the second port. 7. The dispensing device according to claim 1, the outlet port being selectively opened and closed by the insert when the end piece moves following the first displacement. 8. The dispensing device according to claim 1, the end piece being mounted movably relative to the insert following the third displacement. 9. The dispensing device according to claim 8, the insert having several passages of different sizes, the third displacement placing selectively one of said passages in communication with the second port. 10. The dispensing device according to claim 1, the end piece forming one of the first and second actuating element, the other of said elements including means of driving said end piece in the corresponding displacement. 11. The dispensing device according to claim 10, the first actuating element including a ring mounted so that it can rotate around the end piece to move said end piece in translation on the first displacement. 12. The dispensing device according to claim 1, the support including a passage permitting said reservoir to be in communication with the second port. 13. The dispensing device according to claim 1, the support including a means for mounting said device in the opening of a reservoir for the first fluid, said means being arranged to place said reservoir in communication with the first port. 14. The dispensing device according to claim 1, the insert including a plurality of projections to selectively stop the end piece at one of a plurality of positions relative to the insert. 15. A dispensing device for a drink based on a first fluid to which a second fluid can be added selectively, said device comprising: a support containing a dispensing chamber having a first port communicating with a reservoir of said first fluid, a second port communicating with a reservoir of said second fluid, and an outlet port for said first and/or second fluids, anda dispensing assembly mounted movably relative to said support following: a first displacement arranged to open and close said outlet port and/or the first port selectively, said device including a first actuating element for said first displacement, anda second displacement arranged to open and close said second port selectively, said device comprising a second actuating element to enable the actuation of said second displacement;the second actuating element being arranged to be actuated, after the actuation of the first element and following a type of motion which is different to the motion necessary to actuate said first element, the dispensing assembly being mounted movably in relation to the support following a third displacement, which is arranged to control the size of the opening of the second port, further including a third actuating element for the third displacement, said third actuating element being arranged to be actuated in a type of motion which is different to the type of motion necessary for actuating the second actuating element. 16. The dispensing device according to claim 15, the third actuating element being arranged to drive the dispensing assembly in rotation at the third displacement. 17. A dispensing device for a drink based on a first fluid to which a second fluid can be added selectively, said device comprising: a support containing a dispensing chamber having a first port communicating with a reservoir of said first fluid, a second port communicating with a reservoir of said second fluid, and an outlet port for said first and/or second fluids, anda dispensing assembly mounted movably relative to said support following: a first displacement arranged to open and close said outlet port and/or the first port selectively, said device including a first actuating element for said first displacement, anda second displacement arranged to open and close said second port selectively, said device comprising a second actuating element to enable the actuation of said second displacement;a third displacement, which is arranged to control the size of the opening of the second port;the second actuating element being arranged to be actuated, after the actuation of the first element and following a type of motion which is different to the motion necessary to actuate said first element, the assembly being mounted movably such that the first and/or second displacements can be effected independently of the third displacement.
