CA 2180562

In a radiator valve a second throttle point which is formed by a gap (119) between an annular face (114) surrounding the valve seat and the end face of an insert (113) is located downstream of a first throttle point between the valve seat (108) and the closure member (109). The gap (119) is axially offset with respect to the valve seat (108). In particular, the valve seat (108) projects beyong the annular face (114). In this manner, valve noise can be considerably reduced.

Selon la présente invention, un robinet de radiateur comporte un second point d'étranglement constitué par l'intervalle (119) laissé libre entre une face annulaire (114) entourant le siège du robinet et la face d'extrémité d'un insert (113) mis en aval d'un premier point d'étranglement situé entre le siège du robinet (108) et l'obturateur (109). Cet intervalle (119) est axialement décalé par rapport au siège du robinet (108). En particulier, le siège du robinet (108) déborde au-delà de la face annulaire. Ce procédé permet de réduire considérablement le bruit émis par le robinet.
