The invention refers to an apparatus for a controlled delivery of a liquid prepa- ration from a cylindrical liquid container, which has a liquid outlet at its front end and a movable wall, which acts like a piston, at its rear end. The driving force acting on the movable wall for expelling the liquid from the container is generated by means of a piston rod in connection with a pis- ton, which by the action of the atmospheric pressure is urged into a space where a vac- uum has been established. According to the invention, the amount delivered can be varied according to different modes by pro- viding an auxiliary force which acts on the piston during the initial stage of its move- ment into the vacuum space.
L'invention concerne un appareil pour la distribution contrôlée d'une préparation liquide à partir d'un conteneur à liquide cylindrique qui comporte une sortie du liquide à son extrémité avant et une paroi déplaçable qui agit comme un piston, à son extrémité arrière. La force d'entraînement pour agir sur la paroi déplaçable pour évacuer le liquide du conteneur, est générée au moyen d'une tige de piston reliée à un piston qui, sous l'action de la pression atmosphérique est poussé dans un espace où le vide a été établi. Selon l'invention, la quantité distribuée peut varier selon les différentes manières de fournir une force auxiliaire qui agit sur le piston pendant l'étape initiale de son mouvement dans l'espace sous vide.
