Fluid delivery device
Fluid delivery systems and methods for using fluid delivery systems are rotatable around two axes. In one embodiment, the fluid delivery system has a reduced swing radius and/or a reduced clearance area needed to rotate the fluid delivery device about one of the axes. The reduced swing radius and/or reduced clearance area allow for a more compact footprint of the fluid delivery system and a larger ratio of flow rate of fluid per unit of required clearance area.
