THERMOSTATIC CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2018/042050
Kind Code:
A9
Abstract:
This thermostatic cartridge (1) has a hollow casing (10); a thermostatic element (30); a return spring (40); a slide valve (20) which is movably mounted inside a chamber (11) of the casing to regulate the respective amounts of cold fluid (F) and hot fluid (C) entering the chamber, and which is axially translatably coupled to a thermosensitive portion (31) of the thermostatic element; an end piece (50) against which a portion (32) of the thermostatic element, axially translatably actuated by the thermosensitive portion, is axially pressed under the action of the return spring; a nut (60), axially translatably mounted inside the chamber while being rotatably linked to the casing; an overtravel spring (70), axially inserted between the end piece and the nut in order to rigidly connect the end piece and the nut axially, as long as the slide valve can be freely moved axially by the thermosensitive portion; and a screw (80), which is screwed into the nut while being locked against axial translation relative to the casing and which extends from inside the chamber to the outside of the casing via a bore (18) in the casing. The screw has a threaded portion (81) which is screwed inside the nut, and a first screw seat (83) disposed in the bore and which, inside the bore, is guided relative to the casing in order to align the screw with the axis. To limit the clearance of the screw, the latter further includes a second seat (84), which is separate from the threaded portion and the first seat, and which is arranged inside the chamber but outside the bore, the second seat being guided inside the chamber and relative to the casing such that the screw is aligned with the axis.
