Embodiment Construction

[0025] figure 1 In is shown a thermostatic core 1 extending longitudinally about a central axis X-X and intended to equip a mixing tap for water. The following instructions are based on the figure 1 The lower part of the core piece shown in the lower part was made.

[0026] The core 1 has an upper tubular casing 2 and a lower tubular casing 4 centered on the axis X-X and fixed coaxially to each other.

[0027] Housed inside the housing 2 is a core body 10 having an overall cylindrical shape around the axis X-X, with a circular base. The core body 10 defines a cold water introduction duct 11A and a hot water introduction duct 11B over its entire length, ie along the axis X-X direction. The core body 10 also defines, just on its upper part, a cold water return conduit 12A and a hot water return conduit 12B, which open at their lower end into a mixing chamber 13 centered on the axis X-X. The ducts 11A, 11B, 12A and 12B are positioned angularly and radially relative to the axi...

Abstract

According to the invention, the cartridge (1) includes a thermostatic element (72) which is thermally activated by a mixture of a cold fluid and a hot fluid, which is mechanically connected to a regulator slide (70) and which is moved by a single lever (50) for controlling the flow rate and the temperature of said mixture. In order to improve cartridge temperature regulation within a large flow range, the cartridge includes second (30) and third discs (40) in addition to a first disc which is stationary relative to the cartridge body (10). The second disc is translationally stationary relative to the first disc and is capable of rotation under the action of the lever actuation via a nut partially containing a thermostatic-member-moving assembly (76, 78, 80) which is rotatably connected to the control lever about the axis (X-X) and which is provided with extensions (66) that engage mechanically with the second disc for rotating same. The third disc is rotatably connected to the second disc and is capable of translation under the action of the lever actuation. The third disc defines: (a) a cold fluid passage (41A) designed to establish a communication between an inlet (21A) and a return line (22A) for cold fluid, formed through the first disc via an inlet (31A) and a return line (32A) for cold fluid extending through the second disc in order to enable a high flow rate; and (b) a hot fluid passage (41B) designed to establish a communication between an inlet (21B) and a return line (22B) for hot fluid, formed through the first disc via a hot fluid inlet (31B) and a return line (32B) also extending through the second disc in order to enable a high flow rate.

Description

technical field [0001] The invention relates to a single-control thermostatic core, and a mixing faucet including the core. Background technique [0002] Today, many sinks, washbasins and showers are equipped with mixer taps, inside which a ceramic disc insert is arranged. The user controls the relative position of the dials by manipulating the handle so that the volume of cold water supplied to the tap and the volume of hot water also supplied to the tap are mixed before leaving the tap. In this way, the user adjusts the flow rate and temperature of the mixture of cold and hot water in a similar manner. [0003] However, such wicks are not effective in stabilizing the temperature of the fluid exiting the faucet when there are large or sudden changes in the pressure and / or temperature of one of the fluids entering the fluid. WO-A-96 / 26475 has thus proposed integrating thermostatic elements into such cores. To do this, two ceramic plates are stacked: the lower plate is tra...
