<p>A valve intended for installation in the inlet of a thermostatic mixing devi ce comprises a tubular body (1) intended to be inserted in a water supply pipe, a holding seat (2) presented by the body (1), and a cursor (3) that can be mov ed in the body (1) with respect to the seat (2) between a first position (Figur e 12) in which it at least partly occludes the seat (2) and a second position (Figure 13) in which it leaves the seat (2) substantially clear. The cursor (3) is subjected, on the one hand, to the pressure of the water supply pipeline and, on the other hand, to the pressure existing inside the thermostatic mixing device. The valve further comprises a spring (6) that works on the cursor (3), pushing it toward the occlusion position. The valve can also comprise means that act as a nonreturn valve, and it can be equippe d with a flow rate regulator (9).</p> |
