The invention is directed to a device (V) for the output of a liquid (2) in partitioned amounts (2') from a store room (3), preferably in form of a cartridge (K), over an output mouth piece (4), preferably in form of an injection needle (5), and has the object the application of exactly reproducible amounts from a reserve amount and its safe application. This is obtained by an intermediate reservoir (17) taking up the partitioned amount (2') from the store room (3), whereby for the intermediate reservoir (17) an output piston (19) is provided with a penetration canal (18) to fill the intermediate reservoir (17).

L'invention concerne un dispositif (V) pour la distribution de liquide (2) en quantités divisées (2') à partir d'un réservoir (3), de préférence sous la forme d'une cartouche (K), par l'intermédiaire d'un ajutage de distribution (4), de préférence sous la forme d'une aiguille hypodermique (5) montée sur la cartouche. L'invention a pour but de permettre que des quantités exactement reproductibles soient distribuées à partir du réservoir et soient administrées de façon sûre. Ce but est atteint grâce au fait qu'il est prévu un réservoir intermédiaire (17) recueillant les quantités divisées (2') provenant du réservoir principal (3), et auquel est associé un piston de décharge (19) présentant un conduit traversant (18) pour le remplissage du réservoir intermédiaire (17).
