<p>A fluid applicator, e.g. for adhesive, comprises a body (2) defining a reservoir (3) to which fluid is fed under pressure via an inlet (4). An outlet passage (5) is normally closed by a closure member (8). The closure member (8) may be reciprocated at high speed (e.g. 1KH3), and each reciprocation causes a small volume of fluid to be forced by the closure member into the outlet passage, and corresponding volume of fluid to be ejected from nozzle (6) as a small dot. Actuations of the device may be under program control.</p> |
