Problems solved by technology

This spring thus acts as an overtravel spring for the thermostatic element and is essential for the correct operation of the tap, which spring occupies a relatively large space inside the tap body and considerably increases the space requirement in the longitudinal direction of the thermostatic element

Embodiment Construction

[0032] Figures 1 to 4 show a mixer tap cartridge designed to be fitted to a water supply tap, especially for domestic appliances. For convenience, the later part of this specification defines the term "upper" to refer to the upper part of Fig. 2 to Fig. 4, and the term "lower" to refer to its relative direction.

[0033] The spool comprises a rigid body 1 forming a housing, having a substantially cylindrical outer surface with axis X-X. The housing comprises a lower base 2 above which extends a tubular skirt 4 centered on the axis X-X. This defines an interior space 6 delimited at the bottom by the base 2 and at the top by a cover 8 fixedly attached to the upper end of the skirt 4 , for example by clips. The cover 8 has a central opening in which is guided a sleeve 10 fitted with a collar 10A pressed against the lower face of the cover 8 so that the sleeve 10 can rotate about the axis X-X relative to the fixed cover. This rotation is limited by a stop system (not shown) over...

Abstract

The cartridge comprises two ceramic disks (20, 24) for regulating the temperature and flow of a mixture (M) of two entering fluids. In order to ensure that the temperature of the mixture remains lower than a predetermined value, the cartridge comprises thermostatic means (16) designed for, in the event of a high-temperature mixture, automatically shutting off, upstream from these disks, the circulation of the entering fluid (C) of the highest temperature. In order to limit their size, these means comprise: a closure element (34), which serves to close a passage (56) of the fluid (C) having the highest temperature and which is delimited by the cartridge, and; a thermostatic element (36) including a thermosensitive part (38) placed along the flow path of the mixture and a mobile part (40) connected in translation to the closure element, said closure element being mounted in a manner that enables it to slide in an area (42A) of the passage of the fluid of the highest temperature, with the interposition of a packing seal (58), which is joined to this area and which, when the temperature of the mixture is greater than the predetermined value, is capable of forming a sliding tight contact with the closure element.

Description

technical field [0001] The invention relates to a cartridge for a mixer tap, a mixer tap equipped with such a cartridge and a thermostatic assembly for regulating fluid flow. [0002] More particularly, the invention relates to a tap cartridge supplying two fluids having different temperatures, which fluids are to be mixed inside the cartridge by means of at least two ceramic discs movable relative to each other. To vary the relative position of these discs and thereby control the temperature and flow of the mixture, the spool is usually equipped with a single operating member constituted in practice by a lever generally inclined with respect to the central longitudinal axis of the spool. This lever is designed to be operated by the user of the faucet so that, generally, rotation of the lever about the longitudinal axis of the spool changes the temperature of the mixed fluid when the lever is tilted and the flow of the mixed fluid when kept in the same vertical plane. The syn...
