摘要： The present invention relates to an inhalation apparatus for dispensing substances for inhalation and, in particular, but not exclusively for dispensing medicinal products. An inhalation apparatus is provided having a housing defining a socket for receiving a pressurized dispensing container, an actuator for receiving a valve stem of the pressurized dispensing container and a cylindrical chamber having an inlet located at a periphery of the chamber and an outlet at or near a center of the chamber. The actuator defines a duct designed to direct product dispensed from the valve stem of the pressurized dispensing container through the inlet of the cylindrical chamber in a direction substantially tangential to the major axis of the cylindrical chamber, the outlet of the cylindrical chamber communicating with a mouthpiece, such that the inhalation by a user on the mouthpiece creates a cyclonic airflow in the cylindrical chamber between the inlet and outlet in which the dispensed product is entrained for inhalation.
