Embodiment Construction

[0019] figure 1 and 2 Shown is a thermostatic spool C fitted on a mixer tap for sanitary facilities (such as sinks, bathtubs, showers, etc.). The spool is designed to fit inside the faucet assembly for directing the incoming thermal fluid F 1 (actually hot water) and incoming cold fluid F 2 (actually cold water) mixed to deliver the fluid mixture F 3 (Actually, it is mixed water whose temperature is between hot water temperature and cold water temperature).

[0020] As will be explained step by step below, the spool C is adapted to control the mixed water F in a unique way 3 Both temperature and flow.

[0021] Spool C mainly includes:

[0022] ·Main casing 1;

[0023] A thermostatic assembly 2 , described in detail below, adapted to be supplied with hot water F 1 and cold water F 2 And control the temperature of the mixed water F3;

[0024] a pair of ceramic discs 3 and 4 for controlling the flow of hot and cold water delivered to the thermostatic assembly 2, the two...

Abstract

A thermostatic cartridge (C) that comprises a thermostatic assembly (2) for adjusting the temperature of an outflowing mixture (F3) of hot (F1) and cold (F2) incoming fluids, two ceramic disks (3, 4) for controlling the flows of hot and cold fluids supplied to the thermostatic assembly, and a disk-actuation sleeve (5) for sealingly receiving therein the outer body (2.1) of the thermostatic assembly. In order to reduce the costs and the leaking risks of the cartridge, the actuation sleeve is made of a single piece defining two inner circulation channels (52, 53) for the hot and cold fluids, respectively, extending from the disks to respective inlet lumens (2.2, 2.3) defined by the outer body of the thermostatic assembly.

Description

technical field [0001] The invention relates to a constant temperature (temperature control) valve core (core cylinder) used for a mixing faucet. More specifically, the present invention relates to a thermostatic valve cartridge having concentric temperature and flow control means, that is, such a valve cartridge having a first control element and a second control element distinct from the first control element, the first The control element is used to set the temperature of the outgoing fluid obtained by mixing the hot incoming fluid with the cold incoming fluid, said second control element is used to set the flow rate of the outgoing mixture, the two control elements are arranged concentrically assembled so as to be able to operate each of them individually by turning each of them about its own axis. Background technique [0002] In practice, the temperature of the effluent mixture is regulated by a thermostatic element, generally wax-based, while the flow rate of the eff...
