摘要
Thermostatic assembly, in particular thermostatic cartridge This assembly comprises a casing (10), a thermostatic element (30) and a drawer (20). This drawer is movable along an axis (XX) of the element so that a first seat (20.1) of the drawer and a first seat (10.1) of the casing define between them a first passage (P1) which runs around the axis and on which opens a hot fluid inlet (14.1), and that a second seat (20.2) of the spool and a second seat (10.2) of the casing define between them a second passage (P2) which runs around of the axis and on which opens a cold fluid inlet (14.2). These first and second passages are closed when the drawer occupies a first, respectively second, axial position in which the first, respectively second, seat of the drawer bears axially against the first, respectively second, seat of the casing. They are open continuously all around the axis when the drawer occupies an intermediate position between the first and second positions. The drawer is moved by the element so as to close the passages in opposite respective proportions. So that this assembly avoids whistling, it integrates one or more first reliefs (25.1) and one or more second reliefs (25.2), which are arranged in and / or at the inlet of and / or at the outlet of the first, respectively second, passage, and which are shaped to brake, in a non-uniform manner around the axis, the flow of fluid in the first, respectively second, passage when the spool is between the intermediate position and the first, respectively second, position.
