A paddle (5) for a liquid ejection device (1) is located in a chamber (2) and is moveable in a forward direction between a rest state and an ejection state, for ejecting fluid from the chamber through an outlet port (11) as it moves from the rest state to the ejection state. The paddle (5) is positioned to substantially close an inlet port (3) when in the rest state and the paddle (5) and the inlet port (3) define an aperture (16) between themselves. The paddles (5) includes means (12) to reduce fluid flow through the aperture (16) toward the inlet port (3) as the paddle (5) moves from the rest state to the ejection state. |
