Abstract: According to a first aspect of the disclosure, a spray device is provided for generating an aerosol. The spray device comprises a reservoir for containing a store of a liquid; a delivery chamber for containing a dose of the liquid received from the reservoir prior to ejection; a perforate element comprising one or more nozzles; a drive mechanism configured to drive liquid from the delivery chamber through the one or more nozzles; and a fluid metering system. The fluid metering system comprises an actuated valve that is actuatable between a closed position and an open position. The opening and closing of the actuated valve can be sequenced to control the flow of fluid from the reservoir to the delivery chamber.

Abstract: A nozzle assembly, configured to receive fluid at pressures of greater than 1 bar. The nozzle assembly comprises a first perforate element (1) comprising one or more orifices (2), each orifice having an inlet and an outlet and a diameter of no more than 100 μm, and at least one second perforate element (4) further comprising a plurality of orifices of a smaller size than the one or more orifices of the first perforate element (1) and having a larger number of orifices than the first perforate element (1). The second perforate element (4) is configured to act as a filter and the second perforate element (4) is attached to the first perforate element (1). A perpendicular distance between the first and second perforate elements (4) is less than the diameter of the largest orifice of the first perforate element (1).
