A pump (1) for delivery of gas-liquid mixtures adapted to be connected to a container (3) for a liquid (4) comprising: suction means adapted to be reciprocated between a first rest position and a second position so as to collect the liquid from the container; a mixing chamber (12) in communication with the suction means so that when the suction means are moved from a first position to a second position, the liquid is collected from the container and conveyed into a mixing chamber (12); elastic means adapted to displace the suction means back in the first position after that the suction means are moved from a first position to a second position. The elastic means define a variable volume gas chamber (18) in communication with the mixing chamber (12) so that, when the suction means are moved from a first position to a second position, the gas is conveyed into the mixing chamber (12) and a gas-liquid mixture is formed in the mixing chamber.
L'invention concerne une pompe (1) pour la distribution de mélange gaz-liquide, reliée au col (2) d'un contenant (3) de liquide (4), via un bouchon (5), qui comprend: un corps creux généralement cylindrique (6) définissant une chambre (7) pour le liquide à mélanger, en communication avec le contenant par une conduite d'aspiration (8); un piston (9) couplé coulissant avec le corps creux, comportant une tige (10) à canal d'alimentation (11) du liquide (7) vers une chambre de mélange (12) gaz-liquide; un soufflet élastique (13) renvoyant la pompe au repos après une phase de compression manuelle; un premier clapet associé à la chambre à gaz et un second clapet associé à la chambre à liquide; un joint pour ces chambres; une chambre à volume variable (18) pour le mélange gaz-liquide; un distributeur (19) du mélange. La pompe présente en outre un système de collecte (25, 26, 27) de liquide non utilisé pour le mélange et s'échappant de la chambre de mélange (12), qui sort de la tige (10) en descendant dans l'axe de cette tige.
