Abstract

The invention relates to a liquid atomisation or nebulisation device and method involving the use of a propellant gas which is pressure introduced into the device. According to the invention, the two fluids are mixed together and subsequently expelled to the exterior, such that the liquid is released in the form of an aerosol or a suspension of drops that is carried along by the gas current. The inventive device comprises: a liquid storage chamber which is housed in a pressurised cylinder, and a liquid/gas mixing head which is used to combine the two phases and to release same to the exterior. The propellant gas enters the cylinder through an injection nozzle which is located on the upper part of the cylinder and subsequently exits same through a discharge tube, one end of said tube being connected to the above-mentioned mixing head.
