摘要：
The invention relates to a dosing system for an inhalation device which is capable of aliquoting a precise and accurately metered volume from a larger pre-defined fill volume. The dosing system comprises a filling chamber for receiving a liquid to be aerosolized, the filling chamber having a lateral wall, an inlet opening and an outlet opening with a closing means (11) for closing the outlet opening. The dosing system further comprises an overflow chamber surrounding the inlet opening of the filling chamber and a plunger which can be inserted, at least partially, into the filling chamber, and which sealingly contacts the lateral wall such as to displace liquid from said filling chamber upon insertion, and push a metered volume of the liquid out from the filling chamber through the outlet opening and feed it to the nebulizing means of the inhalation device.
