Abstract:
A thermostatic and flow control mixing valve for insertion within a conventional tap body (CR), the thermostatic and flow control mixing valve (CT) comprising:a cartridge mixing valve (CT) for being inserted into the tap body (CR), the cartridge mixing valve (CT) being divided into a first subassembly and a second subassembly, the first subassembly including a thermostatic device having a thermostatic member (13), a slider (14) and a resilient contrast element (16) which are moveable within a mixing chamber for hot and cold water, the mixing chamber being formed in a body (17), the first subassembly controlling a temperature of water passing through the first subassembly, the second subassembly including a valve group having at least one ceramic disk for adjusting a rate of flow of water passing through the second subassembly;a locking element (GF) securing the cartridge mixing valve (CT) within the tap body (CR);a first coupling for operatively coupling a flow rate control member (LP) to the second subassembly to control the flow rate of water through the second subassembly;a second coupling for operatively coupling a temperature control member (MT) to the first subassembly to separately control the temperature of the water flowing through the first subassembly, the first subassembly being removable in an assembled state from the cartridge mixing valve (CT) without removing the second subassembly which is retained in its position by the locking element (GF), the removal of the first subassembly allowing the removal of the thermostatic member, slider and resilient contrast element (13, 14, 16) of the thermostatic device which are moveable within the body (17).
