Raccorderie (20;20') pour la connexion d'éléments thermiques (12, 13, 14, 15) d'un circuit de chauffage (10,10') d'une installation de chauffage d'un bâtiment à sa source de chaleur, p.ex. une chaudière (11), les éléments de chauffage étant reliés entre un raccord de la canalisation montante (18) et un raccord de la canalisation de retour (19) de la chaudière, dans laquelle un agent caloporteur servant au transfert thermique peut être porté à une température d'aller réglable et le caloporteur étant conduit aux éléments de chauffage du circuit de chauffage à l'aide d'une pompe d'alimentation et chaque élément de chauffage étant pourvu d'un raccord de canalisation montante (16) et d'un raccord de canalisation de retour (17) via lesquels, regardé en direction d'écoulement de l'agent caloporteur, l'agent caloporteur chauffé à une température d'aller élevée est conduit à l'élément de chauffage respectif ou, après avoir conduit une partie de la chaleur coulant à travers le circuit de chauffage pour atteindre la température ambiante désirée, le caloporteur est conduit de nouveau à la chaudière, et un dispositif de réglage étant pourvu pour régler la section de passage du chemin d'écoulement de la raccorderie (20;20') conduisant au raccord de la canalisation montante (16) de l'élément de chauffage et la section de passage du chemin d'écoulement de la raccorderie partant du raccord de la canalisation de retour (17) de l'élément de chauffage entre une valeur maximale et l'arrêt total, caractérisée par le fait qu'en tant que dispositif de réglage une vanne 4/3 (74) est prévue sous forme d'un régulateur d'écoulement (74), qui, d'une première position ouverte (I), dans laquelle un raccord (34 ou 36) de la raccorderie (20;20') étant installé dans une connexion fixe avec le raccord de la canalisation montante (16) de l'élément de chauffage respectif (12, 13, 14, 15) est raccordé avec un raccord d'alimentation (42, 44; 81) de la raccorderie (20;20'), et un raccord (34, 36) de la raccorderie (20;20'), étant installé dans une connexion fixe avec le raccord de la canalisation de retour (17) de l'élément de chauffage respectif est raccordé avec un raccord de transfert (43, 46; 82) de la raccorderie (20;20') peut être commuté via une position d'arrêt (0), dans laquelle les raccords d'alimentation et de transfert de la raccorderie (20;20') sont bloqués contre les raccords (34, 36) installés dans une connexion fixe avec les éléments de chauffage respectifs à une position ouverte alternative (II) et complémentaire à la position ouverte (I), et que la vanne 4/3 (74) est dessinée comme vanne proportionnelle, qui, avec l'excursion croissante d'un corps (63) de vanne de sa position de blocage normale en sens de la conduction alternative respective des chemins d'écoulement en positions ouvertes (I et II) débloque des sections de passage croissantes.
  2. Raccorderie selon revendication 1, caractérisée par le fait que la vanne 4/3 (74) est dessinée en tant que vanne rotative avec un corps de vanne de forme cylindrique (63).
  3. Raccorderie selon revendication 1 ou revendication 2, caractérisée par le fait qu'un canal de passage (22) de la raccorderie (20) constitue une section de la canalisation montante, et un canal de passage (23) constitue une section de la canalisation de retour d'un système à deux voies qui peuvent être raccordés via la vanne 4/3 (74) en chemins d'écoulement alternatifs au raccord de la canalisation montante et de retour (16, 17) de l'élément de chauffage respectif (12, 13, 14, 15).
  4. Raccorderie selon revendication 1 ou revendication 2, caractérisée par le fait que la raccorderie (20') a une canalisation principale (86) disposée entre un raccord d'entrée (81) et un raccord de sortie (82), la canalisation principale mentionnée étant pourvue d'un diviseur de débit (87) qui ne développe qu'un faible effet d'étranglement et dérive d'un milieu de courant un courant secondaire s'écoulant à l'élément de chauffage et revenant de l'élément de chauffage via la vanne 4/3 (74).
  5. Raccorderie selon revendication 4, caractérisée par le fait que le diviseur de débit (87) consiste en une tuyère (101) dérivant de l'alimentation en eau chaude le courant secondaire, qui est conduit à la raccorderie (20') via la vanne 4/3 (74), et en outre transférant le courant d'eau chaude à travers la conduite d'eau principale (86), recevant de nouveau le courant secondaire dérivé avant via la vanne 4/3 (74).
  6. Raccorderie selon revendication 5, caractérisée par le fait qu'une tuyère d'injection (102) est pourvue pour réintroduire dans le courant principal l'eau courant de l'élément thermique via la vanne 4/3 dans la canalisation principale (86), les dimensions de la tuyère correspondant à celles du diviseur de débit (101).
  7. Raccorderie selon l'une des revendications 1 à 6, caractérisée par le fait que des actuateurs électriquement commandés (114) sont prévus pour le réglage des sections de passage efficaces des canaux de passage (64, 66) de la vanne 4/3 (74).
