The volume of water in circulation is controlled by means of a bell-type mixer (4) which has a stationary section disc (6) and a somewhat sickle-shaped rotary distributor bell (7). The section disc has at least three separate passage openings, the first of which is connected with the boiler feed pipe (KV), the second (12) with the heating pipe (HV) and the third with the boiler return pipe. The distributor bell (7) is acted upon externally by the heating return water pressure and internally houses à communication duct (19). The distributor bell shunts the boiler feed pipe over a limited area of rotation via the second passage opening (12) with the heating pipe and simultaneously frees a variable area of the opening into the second passage for the admixture of return water. In this way optimal regulation is achieved with little structural, maintenance or operational outlay.
Le volume d'eau de circulation est contrôlé à l'aide d'un mélangeur à cloche (4) comprenant un disque fixe (6) et une cloche de distribution rotative en forme de faucille (7). Le disque fixe comporte au moins trois orifices de passage distincts, le premier étant relié au tuyau d'alimentation de la chaudière (KV), le deuxième (12) au tuyau de chauffage (HV) et le troisième au tuyau de retour. La pression de l'eau de retour de chauffage agit de façon extérieure sur la cloche de distribution (7), laquelle renferme un conduit de communication (19). La cloche de distribution fait faiblement dériver le tuyau d'alimentation, lequel traverse le deuxième orifice de passage (12) avec le tuyau de chauffage et dégage ainsi une portion de dimension variable de l'orifice du deuxième passage pour assurer le mélange de l'eau de retour. On obtient une régulation optimale avec un minimum de complexité constructive et d'interventions au plan de l'entretien ou de l'exploitation.
