The disclosure relates to a device for dynamic control of a water flow, including the following items in a body: a feed chamber, a discharge chamber and a piston arranged between the feed chamber and the discharge chamber. The piston can be displaced from a first position, which is offset towards the feed chamber and wherein the piston narrows the flow between the feed chamber and the discharge chamber, and a second position, which is offset towards the discharge chamber and wherein the piston does not narrow the flow between the feed chamber and the discharge chamber.

What is claimed is: 1. A device for the dynamic control of a flow, comprising, in one body, one inlet chamber, one outlet chamber, one piston, which is positioned between the inlet chamber and the outlet chamber and is flexible between a first position that is moved relative to the inlet chamber, wherein the piston in the first position restricts the flow between the inlet chamber and the outlet chamber, and a second position that is moved relative to the outlet chamber, wherein the piston in the second position does not restrict the flow between the inlet chamber and the outlet chamber, and a retaining spring that acts upon the piston in the first position, wherein the inlet chamber is at least partially circular and surrounds the piston, that the piston involves a cylindrical jacket section that is positioned in the area of the inlet chamber and penetrated by restricted radial passages, and a transversal section, which defines an intermediate chamber and is penetrated by an axially restricted passage, and that the restricted radial passages, the axially restricted passage, and the retaining spring are proportioned relative to each other in such a manner that the effect of the spring is essentially equal to the force that tends to move the piston from the first position to the second position when the maximum flow is diverted, which could cause an instability in a thermostatic mixer, and the intermediate chamber within the body of the device is restricted by an inlet connection, in which an inlet chamber is defined and axially circumferential passages are provided, which flow into the circular inlet chamber, which surround the piston. 2. The device for the dynamic control of a flow according to claim 1, wherein the piston has a jacket section, in which the restricted passages are provided. 3. The device for the dynamic control of a flow according to claim 2, wherein the restricted passages are formed from small recessions that are provided in the edge of the jacket section. 4. The device for the dynamic control of a flow according to claim 3, wherein the jacket section is thin. 5. The device for the dynamic control of a flow according to claim 2, wherein the restricted passages are formed from holes, which are provided in the jacket section. 6. The device for the dynamic control of a flow according to claim 1, wherein in addition to, or instead of, the restricted passages, a small space is provided between the body and the piston. 7. The device for the dynamic control of a flow according to claim 1, wherein the inlet chamber and the axially circumferential passages are built as passages, which are designed into an auxiliary element that is installed between the body of the device and the inlet connection of which it forms a part. 8. The device for the dynamic control of a flow according to claim 7, wherein the auxiliary element is manufactured from stamped plastic material. 9. The device for the dynamic control of a flow according to claim 1, wherein the piston in its first closed position can fit against a plane surface of the inlet connection. 10. The device for the dynamic control of a flow according to claim 1, wherein the piston in its first position partially engages into a seat, which is built on a plane surface of the inlet connection. 11. The device for the dynamic control of a flow according to claim 1, wherein the inlet connection has a protrusion, which will shift into the restricted passage and partially shut off the same when the piston is in its first position, and will not shut it off when the piston is in its second position. 12. The device for the dynamic control of a flow according to claim 1, wherein it is installed into a stopcock. 13. The device for the dynamic control of a flow according to claim 12, wherein the direction of the shifting of the piston and the axis of a closing element of the stopcock coincide. 14. The device for the dynamic control of a flow according to claim 1, wherein it is installed in-series into the cold in-flow water of a thermostatic mixer for the purpose of stabilizing it. 15. A stopcock for installation in series into the cold water in-flow of a thermostatic mixer, wherein the stopcock contains a device for the dynamic control of a flow according to claim 1.
