Abstract
An ejection nozzle arrangement is provided having a fluid chamber having a wall and a fluid port, an arm extending through an aperture in the wall, a dynamic structure cantilevered from the wall adjacent the aperture, a static structure cantilevered from the wall adjacent the dynamic structure. The arm is connected to the dynamic and static structures at a point distal from the aperture such that thermal expansion of the dynamic structure moves the arm upwards in the chamber to eject fluid from the chamber through the port.
