Abstract

L’invention concerne une pompe de circulation d’un fluide, et une installation comprenant une telle pompe, trouvant notamment une application aux installations hydrauliques de type installation de chauffage ou de fourniture d’eau chaude. La pompe comprend une chambre d'admission 1 présentant un premier et un deuxième orifices d'entrée 2, 3 de fluide, une chambre de refoulement 4 présentant un orifice de sortie 5 de fluide, un organe d'entraînement pour entraîner le fluide de l'un des premier et deuxième orifices d'entrée 2, 3 vers l'orifice de sortie 5, un organe d'obstruction sélectivement actionnable pour obstruer le premier ou le deuxième orifice d'entrée 2, 3, et un organe d'actionnement 7 solidaire de l'organe d'obstruction et configuré pour actionner ledit organe d'obstruction. La pompe comprend également un premier support 8 monté sur la chambre d’admission 1, l’organe d’actionnement 7 étant monté sur un deuxième support coopérant avec le premier support 8 pour assurer le couplage amovible de l’organe d’actionnement 7 avec l’organe d’obstruction, en sorte de permettre d’assembler sans outils l’organe d’actionnement 7 avec l’organe d’obstruction et de désassembler sans outil l’organe d’actionnement 7 de l’organe d’obstruction, par assemblage et désassemblage des premier et deuxième supports. Figure pour l’abrégé : figure 1The invention relates to a fluid circulation pump, and an installation comprising such a pump, finding in particular an application to hydraulic installations of the heating or hot water supply type. The pump comprises an inlet chamber 1 having first and second inlet orifices 2, 3 for fluid, a discharge chamber 4 having an outlet orifice 5 for fluid, a drive member for driving the fluid from the one of the first and second inlet orifices 2, 3 towards the outlet orifice 5, an obstruction member selectively operable to obstruct the first or the second inlet orifice 2, 3, and an actuating member 7 secured to the obstruction member and configured to actuate said obstruction member. The pump also comprises a first support 8 mounted on the inlet chamber 1, the actuating member 7 being mounted on a second support cooperating with the first support 8 to ensure the removable coupling of the actuating member 7 with the obstruction member, so as to allow the actuating member 7 to be assembled without tools with the obstruction member and the actuating member 7 to be disassembled without tools from the obstruction member, by assembling and disassembling the first and second supports.
