Abstract
A thermostatic valve contains a control system, which can be actuated by a single operating member. It produces a connection between a cold water inlet and a hot water inlet on the one hand and a mixed water outlet on the other. The control system can in particular have two control disks, whereof one is constructed as a fixed control disk and the other as a rotatable control disk in contact therewith. The control system is designed in such a way that on opening initially only cold water flows out of the outlet. This is achieved in that a direct connection is formed between the cold water inlet and the mixed water outlet. Only on further opening the valve is it ensured that the direct connection is closed, so that the cold water must then flow through the thermostatic valve.
Claims9
Mixing fitting with single lever operation, comprising a cold water inlet, a hot water inlet, a thermostatic valve, a mixed water outlet and a control system for the connection of inlets and outlets via the thermostatic valve, wherein the control system has a position in which both a direct connection is formed between the cold water inlet and the mixed water outlet and an indirect connection is formed between the cold water inlet and the mixed water outlet via the thermostatic valve.
