Abstract

Pompe présentant un bruit de fonctionnement réduit. Le groupe d'alimentation comporte une pompe 1 et un moteur électrique 2 placés dans un carter 3 comportant un couvercle 5, des raccordements d'entrée 4 et de sortie 6 et une soupape antiretour 7. L'axe 12 est emmanché dans la plaque de base il sur laquelle sont vissées la plaque intermédiaire 13 et la plaque d'appui 14 de même axe. Le rotor de pompe 17 est porté par l'axe 12 grâce au palier 18. La pompe possède une chambre d'admission 19 et une chambre de refoulement 21 reliées par une soupape de commande 21. Le tube 28 tourne autour de l'axe 12 sur des coussinets 27. Il supporte la carcasse 29, l'enroulement 30 et le collecteur 31 du moteur électrique qui possède un induit 23 et une pièce magnétique 25. L'accouplement entre la pompe 1 et le moteur 2 se fait par le taquet 33 et l'encoche 34. L'aimant permanent 38 est placé dans le tube en tôle magnétique 39. Les réservoirs 41 et 42 peuvent subir des déformations élastiques.
