Abstract
A thermostatic valve contains a control system comprising two disks for the quantity control. One of the two disks is placed in fixed manner in the valve casing, whereas the second disk can be rotated. Each of the two disks contains an inlet opening for cold water and an inlet opening for hot water. These openings are made to coincide to a greater or lesser extent for the quantity control. In addition, each of the control disks contains a subdivided outlet opening for the mixed water leaving the valve. On rotating the valve there is also a modification of the flow cross-section of the outlet opening. This is also brought about by a greater or lesser coincidence of the openings.
