Abstract: An aerosol generator for generating an inhalation aerosol from an inhalation liquid, includes an intake duct for guiding air to a mouth of a user, and a nozzle, arranged in the intake duct for injecting the inhalation liquid into the intake duct. The nozzle is arranged for generating a Rayleigh droplet train of the inhalation liquid propagating along a droplet train propagation path. The intake duct includes at least two first orifices having at least partly opposing discharging directions extending towards the droplet train propagation path. The at least two first orifices are configured for providing respective first air streams in at least partly opposing directions so as to interact in the droplet train propagation path.

Abstract: A method of manufacturing an atomizing body for an atomizing device includes the steps of providing a support element having a first layer on a first surface of the support element and a second layer on a second surface of the support element, the first layer including a first perforated membrane and the second layer including a process orifice, etching a cavity through the support element, the cavity forming a fluid connection from the process orifice to the perforated membrane, by providing etching substance to the process orifice. The atomizing body as obtained may advantageously be applied in an atomizing device or an inhaler.

Abstract: An atomizing device, includes an atomizing body (1) with an inlet (16) for receiving a fluid under increased pressure, and with at least one set of outflow ports (18) for allowing the fluid to escape on a delivery side with forming of a vapor. Imaginary central axes of the outflow ports directed in a flow direction herein enclose a mutual angle (?) in order to intersect each other at an intersection (S). The atomizing body includes a roof (21) and a bottom (11 which extend over at least a first distance (d1) beyond the set of outflow ports (18) and bound a vaporizing space (17) on either side. The intersection (S) of the imaginary central axes of the outflow ports lies at a second distance (d2) from the set of outflow ports, wherein the second distance (d2) is greater than the first distance (d1) and extends beyond the vaporizing space.

Abstract: Nozzle device and nozzle for atomisation and/or filtration as well as methods for using the same. The present invention relates to a nozzle and nozzle device for atomisation, in particular a micro-machined reinforced nozzle plate, that may produce small liquid droplets in air (spray) or into a liquid (emulsion) with a narrow droplet size distribution and to make small air bubbles into a liquid (foam) and to methods of making the same. The invention is further related to a nozzle part for filtration as well as means and methods to facilitate atomisation and filtration.
