Abstract
The thermostatic cartridge (C) comprises a thermostatic assembly (2) for regulating the temperature of an outgoing mixture (F3) of incoming hot and cold fluids (F1 and F2), two ceramic disks (3, 4) for controlling the flow rates of the hot and cold fluids delivered to the thermostatic assembly, and a disk-actuating sleeve (5) receiving therein in leaktight manner the outer body (2.1) of the thermostatic assembly. To limit costs and any risk of leakage from the cartridge, the actuator sleeve is a single part that defines two internal channels (52, 53) for passing flows respectively of the hot and cold fluids from the disks to respective admission slots (2.2, 2.3) defined by the outer body of the thermostatic assembly.
Claims11
A thermostatic cartridge with concentric temperature and flow rate controls, the cartridge comprising:
- a thermostatic assembly for regulating the temperature of an outgoing mixture of incoming hot and cold fluids, said thermostatic assembly comprising an outer body that defines first and second admission slots respectively for the hot and cold fluids;
- a control assembly for controlling the flow rates of the hot and cold fluids sent to the first and second slots;
- and
- an actuator sleeve for actuating the control assembly, the actuator sleeve receiving in leaktight manner at least a portion of the outer body of the thermostatic assembly;
- wherein the actuator sleeve is a single part that defines both a first internal channel for passing a flow of the hot fluid from the control assembly to the first slot, and a second internal channel for passing a flow of the cold fluid from the control assembly to the second slot.
