Abstract
A fluid droplet production apparatus, for example, for use an atomizer spraying device, has a membrane which is vibrated by an actuator, which has a composite thin-walled structure and is arranged to operate in a bending mode. Fluid is supplied directly to a surface of the membrane, as fluid is sprayed therefrom on vibration of the membrane.
Claims15
Fluid droplet production apparatus comprising a membrane;
- an actuator, for vibrating the membrane, the actuator comprising a composite relatively thin-walled structure arranged to operate in a bending mode having a direction of bending and to vibrate the membrane substantially in the direction of actuator bending;
- and
- means for supplying fluid directly to a surface of the membrane, as fluid is sprayed therefrom on vibration of the membrane.
