1. A drink preparing machine comprising: a tank;a water supply system comprising at least a section for heated water and a section for unheated water;a pump for conveying water from the tank through the supply system as far as a module for preparing the drink; anda valve device arranged so as to control the selective opening and closing of the supply system sections;wherein the valve device is a peristaltic system comprising a first tube in fluid association with the heated section water, a second tube in fluid association with the unheated section water, and compression means compressing a tube of each supply system section and acting under the effect of elastic return means comprising a spring;wherein the tubes are arranged to assume a neutral position, or a selective closed-off/open positions comprising a closed-off position of one tube and an open position of the other tube, with the compression means engaging the two tubes with sufficient return tension to keep both tubes simultaneously closed when in the neutral position; and with the compression means selectively providing a greater tension on one of the tubes so as to close off that tube and at least partially open the other tube when the tubes are in the selective closed off/open position. 2. The machine according to claim 1, wherein the valve device controls the selective opening and closing of the first and second tubes passing through the device, and further comprises: actuating means fixed to a rocker body;a base on which the body is mounted in order to rock about the neutral and selective closed/open positions;wherein the tube compression means is mounted on the base and able to be displaced against the elastic return means by actuating the actuating means. 3. The machine according to claim 2, wherein the elastic return means is arranged with respect to the rocker body in order to: close both tubes in the neutral position; andclose one tube while maintaining the other tube open in the selective closed/open positions. 4. The machine according to claim 2, wherein the actuating means comprises a lever. 5. A drink preparing machine for preparing hot and cold drinks, comprising: a control device comprising a peristaltic valve for controlling the selective opening and closing of first and second tubes passing through the device, with the device comprising:actuating means fixed to a rocker body;a base on which the body is mounted in order to rock about at least one neutral position, two selective closed/open positions of the tubes comprising a closed position of a first tube and an open position of a second tube and an open position of the first tube and a closed position of the second tube; andtube compression means mounted on the base and able to be displaced against elastic return means by actuating the actuating means, wherein the elastic return means comprises at least one return spring provided between the body and the compression means;wherein the elastic means are elastic return means arranged with respect to the rocker body in order to:in the neutral position, keep the compression means in the closed position against the two tubes with sufficient return tension to keep the two tubes closed; andin the selective closed/open positions of the tubes, keep the compression means selectively with a greater tension on one of the tubes so as to close one of the tubes and at least partially open the other tube;wherein the tubes include a first tube for providing heated water, and a second for providing unheated water. 6. The machine according to claim 5, wherein the return spring is arranged so as to provide a stable position of the compression means in the selective closed/open position of the tubes. 7. A drink preparing machine for preparing hot and cold drinks, comprising: a control device comprising a peristaltic valve for controlling the selective opening and closing of first and second tubes passing through the device, with the device comprising:actuating means fixed to a rocker body;a base on which the body is mounted in order to rock about at least one neutral position, two selective closed/open positions of the tubes comprising a closed position of a first tube and an open position of a second tube and an open position of the first tube and a closed position of the second tube, wherein the rocker body is mounted on the base on at least two parallel rotary pins, each pin forming the rotary displacement of the body with respect to the base towards one of the selective closed/open positions of the tubes; andtube compression means mounted on the base and able to be displaced against elastic return means by actuating the actuating means;wherein the elastic means are elastic return means arranged with respect to the rocker body in order to:in the neutral position, keep the compression means in the closed position against the two tubes with sufficient return tension to keep the two tubes closed; andin the selective closed/open positions of the tubes, keep the compression means with a greater tension on one of the tubes so as to selectively close one of the tubes and at least partially open the other tube;wherein the tubes include a first tube for providing heated water, and a second for providing unheated water. 8. The machine according to claim 7, wherein that the tube compression means comprises two pinching arms pivoting on the base. 9. The machine according to claim 8, wherein the compression means pinch the tubes against a bearing surface of the base. 10. The machine according to claim 9, wherein the bearing surface of the base constitutes a convex surface. 11. The machine according to claim 8, wherein the pinching arms are linked to the rocker body of the lever by two springs or two spring portions constituting the elastic return means, the latter being arranged so as to assume a stable position passing beyond the axis of rotation during the rotary displacement of the body with respect to the base towards one of the selective closed/open positions of the tubes. 12. The machine according to claim 11, wherein the springs have their points of attachment to the rocker body and to the said pinching arms arranged in such a manner that they intersect in the projection of the longitudinal plane to the base. 13. A drink preparing machine for preparing hot and cold drinks, comprising: a control device comprising a peristaltic valve for controlling the selective opening and closing of first and second tubes passing through the device, with the device comprising:actuating means fixed to a rocker body;a base on which the body is mounted in order to rock about at least one neutral position, two selective closed/open positions of the tubes comprising a closed position of a first tube and an open position of a second tube and an open position of the first tube and a closed position of the second tube; andtube compression means mounted on the base and able to be displaced against elastic return means by actuating the actuating means;wherein the elastic means are elastic return means arranged with respect to the rocker body in order to:in the neutral position, keep the compression means in the closed position against the two tubes with sufficient return tension to keep the two tubes closed; andin the selective closed/open positions of the tubes, keep the compression means selectively with a greater tension on one of the tubes so as to close one of the tubes and at least partially open the other tube; andat least one control switch for actuating a pump which is configured to convey water to the tubes for preparing a drink, with the actuating means acting on the switch;wherein the tubes include a first tube for providing heated water, and a second for providing unheated water. 14. The machine according to claim 13, wherein the actuating means comprises a lever. 15. The machine according to claim 13, which further comprises a pump configured to be turned on in the selective closed/open positions of the tubes. 16. The machine according to claim 5, which further comprises a pump configured to be turned on in the selective closed/open positions of the tubes.
