Abstract
Droplet deposition apparatus comprising first and second channels (82a, 82b), one end of each channel communicating with a single, common supply chamber (40) for supply of droplet liquid and the respective other ends of the first and second channels each communicating with a respective further supply chamber (88, 92) for supply of droplet liquid; each of said first and second channels having an opening (96a, 96b) for ejection of droplets therefrom; and actuator means being associated with each channel for effecting the ejection of droplets.
Claims23
Droplet deposition apparatus comprising:
- a body of piezoelectric material mounted on and supported by a base, the body being formed with at least one channel open on one side, the channel communicating at each end with a supply chamber for supply of droplet fluid, the body being formed with actuator means associated with each channel for effecting ejection of droplets;
- a cover closing the open side of the at least one channel and having formed therein at least one opening for ejection of droplets from the channel;
- the base defining with the cover the supply chambers communicating with the respective ends of the at least one channel.
Droplet deposition apparatus comprising:
- a body formed with at least one chamber open on one side, each chamber communicating with an opening for ejection of droplets therefrom and with a manifold for supply of droplet fluid, actuator means being associated with each chamber for effecting ejection of droplets in response to electrical signals and a cover closing the open side of the at least one chamber;
- the manifold being defined at least in part by a base, the base also defining at least in part a further chamber, control means for supplying the electrical signals to the actuator means being located in the further chamber.
Droplet deposition apparatus comprising a body formed with at least one chamber having an open side, each chamber communicating with a supply of droplet fluid and an opening for ejection of droplets therefrom;
- actuator means being associated with each chamber for effecting ejection of droplets in response to electrical signals, a support member for said body, the support member closing the open side of said chamber and having at least one track thereon for conveying electrical signals to respective actuator means, and having formed therein at least one opening for ejection of droplets from respective chambers.
