Patent

CA 2602052

A volumetric pump (1) comprising at least one piston (2) in a hollow cylinder (3), said pump (1) having at least one inlet port (10) through which a liquid (15) can be sucked into a pump chamber (3) during an instroke of said piston (2), and at least one outlet port (11) through which the liquid (15) can be expelled during an outstroke of the piston (2). Said piston (2) or the hollow cylinder (3) of the volumetric pump (1) can be actuated directly or indirectly by at least one rotor (5). This rotor (5) transmits, on the one hand a bi- directional linear movement to the piston (2) or to the cylinder (3) causing said piston (2) to slide back and forth inside said cylinder (3) or following the axis of said piston (2), and on the other hand, a bi-directional angular movement either to the piston (2) or to a disc (24) in order to open and close alternately the inlet and outlet ports (10, 11).

L'invention concerne une pompe volumétrique (1) comprenant au moins un piston (2) dans un cylindre creux (3), cette pompe (1) possédant au moins un orifice d'entrée (10) à travers lequel un liquide (15) peut être aspiré dans un corps de pompe (3') durant un déplacement vers l'intérieur du piston (2), et au moins un orifice de sortie (11) à travers lequel le liquide (15) peut être expulsé durant un déplacement vers l'extérieur du piston (2). Ce piston (2) ou le cylindre creux (3) de la pompe volumétrique (1) peuvent être actionnés directement ou indirectement par au moins un rotor (5). Ce rotor (5) transmet, sur une bande de mouvement linéaire bidirectionnelle à partir du piston (2) ou vers le cylindre (3) entraînant le coulissement vers l'avant et vers l'arrière du piston (2) à l'intérieur du cylindre (3) ou suivant l'axe de ce piston (2), et d'autre part, un mouvement angulaire bidirectionnel vers le piston (2) ou vers un disque (24) afin d'ouvrir et de fermer en alternance les orifices d'entrée et de sortie (10, 11).
