Summary:The invention relates to a vacuum pump for applications in vacuum packaging machines, comprising: a cylinder (11) consisting of the envelope of two parallel, transversely intersected cylindrical chambers, the axes of said chambers lying in the same plane and one of the faces of said chambers being a wall on which the suction opening (17) is provided, and also of the outer envelope surrounding the envelope of two parallel cylindrical chambers in order to form a confined space provided with an inlet and an outlet, enabling a fluid carrying out the heat exchange to circulate; and a driving housing (12) containing the motor and the components for driving and synchronising the pumping rotors, that hold said rotors in an overhanging manner and are used to support and centre the cylinder (11). Cette demande se rapporte à une pompe à vide pour applications dans les machines d'emballage sous vide, comprenant un cylindre (11), constitué de l'enveloppe de deux chambres cylindriques parallèles, intersectées transversalement, et dont les axes reposent dans un plan, et dont une des faces représente une paroi sur laquelle se trouve l'orifice d'aspiration (17), et de l'enveloppe extérieure englobant l'enveloppe de deux chambres cylindriques parallèles pour former un espace confiné, muni d'une entrée et d'une sortie, qui permet de faire circuler un fluide effectuant de l'échange thermique, et un carter d'entraînement(12) contenant le moteur, les composants d'entraînement et de synchronisation des rotors de pompage, supportant lesdits rotors en porte-à-faux et servant d'appui et de centrage au cylindre (11).
