    Abstract: The invention provides exemplary methods and apparatus for dispensing liquids as an atomized spray. In one particularly preferably method, a liquid is dispensed as an atomized spray from a vibratable member having a front surface and a rear surface, with the member having at least one tapered hole between the surfaces for dispensing the liquid. The tapered hole has a larger cross-sectional area at the rear surface than at the front surface. The liquid is delivered from a supply container to the rear surface of the vibratable member in an amount sufficient to cover the hole with liquid. The vibratable member is then vibrated to dispense at least a portion of the liquid through the hole and from the front surface. Additional liquid is delivered from the supply container and to the rear surface in volumes that are substantially equal to the volumes dispensed.

    Abstract: The invention provides methods and apparatus for nebulizing liquids. In one exemplary embodiment, an apparatus is provided which comprises a thin shell member having a front surface, a rear surface, and a plurality of apertures extending therebetween. The apertures are tapered to narrow from the rear surface to the front surface. A liquid supplier is further provided which delivers a predetermined unit volume of liquid to the rear surface. A vibrator vibrates the thin shell member to eject liquid droplets from the front surface of the thin shell member.

    Abstract: A fluid injection device for ejecting fluid droplets in response to electrical signals comprises an oscillating surface that has one or more tapered apertures, each aperture having a first and second opening. The first opening of each aperture is larger than the second opening. The first opening is in surface tension contact with the fluid to be ejected. The fluid interaction with the tapered aperture wall creates cycles of fluid compression and decompression inside the aperture, causing fluid to be drawn from the large opening and ejected out the small opening of the aperture. The device includes a fluid supply nozzle that transports fluid to the oscillating surface at the large opening of the apertures. A discharge valve controls the fluid supply. An electronic wave generator induces oscillation in the tapered aperture containing surface. The device is used to great advantage for fluid atomization and fluid spray.

    Abstract: An aerosolization system comprises a gas flow passage, and an aerosol generator comprising a plate having a plurality of apertures and a vibratable element disposed to vibrate the plate. The aerosol generator is adapted to aerosolize a liquid for delivery into the gas flow passage. A flow sensor is configured to sense a gas flow through the passage, and a controller is employed to actuate the aerosol generator based on the gas flow sensed by the flow sensor.
