A nebulizer for nebulizing a liquid from a container, where the nebulizer includes a fluid pump for withdrawing the liquid in doses from the container and pressurizing the respective doses for nebulization. The container includes an air pump with a piston/cylinder arrangement to pressurizing the liquid in the container to help withdrawing the liquid from the container. A control valve limits the air pressure acting on the liquid. 112. A nebulizer () for nebulizing a liquid () , comprising:{'b': 3', '2, 'a preferably replaceable container () containing multiple doses of the liquid (),'}{'b': 5', '2', '3, 'a fluid pump () for withdrawing a dose of the liquid () from the container () and pressurizing the respective dose for nebulization,'}{'b': 30', '2', '3', '2', '3, 'an air pump () for pressurizing the liquid () in the container () to help withdrawing the liquid () in doses from the container (), and'}{'b': 18', '1', '3, 'preferably a housing part () which can be detached from the nebulizer () or opened for inserting or replacing the container (),'}{'b': 1', '30', '44', '2', '3', '3', '2, 'wherein the nebulizer () or air pump () comprises a control valve () limiting the air pressure acting on the liquid () in the container () to a maximum value above the ambient pressure (PA) independently from a filling level of the container () with the liquid ().'}212. The nebulizer () for nebulizing a liquid () claim 1 , according to claim 1 , comprising:{'b': 3', '2, 'a preferably replaceable container () containing multiple doses of the liquid (),'}{'b': 5', '2', '3, 'a fluid pump () for withdrawing a dose of the liquid () from the container () and pressurizing the respective dose for nebulization,'}{'b': 30', '2', '3', '2', '3, 'an air pump () for pressurizing the liquid () in the container () to help withdrawing the liquid () in doses from the container (), and'}{'b': 18', '1', '3, 'preferably a housing part () which can be detached from the nebulizer () or opened for ...
