Abstract: A nebulizer has an aerosol generator mounted in a housing, and has a vibratable aperture plate mounted to an annular support and to which is attached a vibration generator piezo. A downstream annular resilient seal is mounted between the housing and the washer on a side of the aperture plate opposed to the liquid supply reservoir. An upstream resilient seal is in the form of a gasket and is mounted between the washer and the housing reservoir, and has an opening forming part of a throat over the aperture plate. The gasket has a washer-shaped body extending radially from a downstream-extending rim adjacent the aperture plate. There are two upwardly-directed ridges for engagement with a housing surface, and the gasket is configured so that when under axial compression the opening internal surface is tapered inwardly in a flow direction to form a funnel shape.
