Abstract
The invention concerns a thermostatic valve to control the delivery of hot, cold and mixed water, that comprises a thermostatic bulb (17) in connection with a mixer control device (19), which solicited by a spring (21) that rests against it by means of a cap (28) for a uniform action of the spring on all the contact surface of the cap with said device. Furthermore the control device (19) has some radial holes (194) to convey the water towards the thermostatic bulb in a more satisfactory way.
Claims20
Thermostatic valve for the control of the delivery of mixed water, comprising a cartridge body and, coaxially inside said body, a thermostatic bulb (20) and a mixing control device (19) associated and connected together, and where
- the cartridge body has, at different levels, some radial holes or conduits (15, 16) for an input of respectively hot and cold water to a mixing chamber (17) with an output opening of mixed water towards a user point;
- the thermostatic bulb (20) and the mixer control device (19) are positioned in said mixer chamber, together with said control device operating on a level with said hot and cold input holes or conduits;
- said mixer control device is susceptible to axial movements in response to dilatations the thermostatic bulb is subject to as the temperature of the water changes;
- and
- the movements of the mixer control device are opposed by two different opposite springs (22, 23) respectively associated with the device itself and with a cover resting on the summit of the thermostatic bulb;
- wherein between the mixer control device (19) and the spring (22) associated with it there is a cap (28) for a uniform distribution of the thrust of said spring (22) on all the contact surface of said cap with said control device.
