Patent abstract
The present invention relates to an improved controllable valve, in particular for an inhalation device, which, e.g., comprises a container for a predetermined aerosol volume, a means for disbursing an aerosol from an aerosol dispenser into the container and a control means that keeps the inhalation flow essentially constant during the entire inhalation. The control means comprises an either continuously or gradually controllable valve so as to limit the flow rate.
