CA 2352112

The invention concerns a device comprising a first calibrated or adjustable orifice (34) and a second orifice (36) located downstream of the first orifice (34). The opening of the second orifice (36) is adjusted by a valve (38) whereof the position is controlled by means (46, 56) displacing the valve depending on the pressure difference (P2-P1) prevailing between upstream and downstream of the first orifice (34) and by means (48) producing a displacement depending on the temperature of the premises wherein the device is located. Said device is mounted in two separate bodies (88, 90), mutually linked, a first body (90) corresponding to the first orifice (34) and a second body (88) corresponding to the second orifice (36). The device enables to produce both automatic hydraulic balancing and thermostatic control.

Ce dispositif comporte un premier orifice (34) calibré ou réglable, ainsi qu'un second orifice (36) situé en aval du premier orifice (34). L'ouverture du second orifice (36) est réglée d'une part par un clapet (38) dont la position est commandée par des moyens (46, 56) permettant le déplacement du clapet en fonction de la différence de pression (P2-P1) existant entre l'amont et l'aval du premier orifice (34) et d'autre part par des moyens (48) permettant de réaliser un déplacement en fonction de la température du local dans lequel se trouve le dispositif. Ce dispositif est monté dans deux corps (88, 90) distincts, reliés l'un à l'autre, un premier corps (90) correspondant au premier orifice (34) et un second corps (88) correspondant au second orifice (36). Ce dispositif réalise à la fois un équilibrage hydraulique automatique et une régulation thermostatique.
