Abstract:
1. A system for priming a fluid jetting device, the system comprising: a fluid trench configured within a fluid jetting chip of the fluid jetting device; at least one flow feature channel disposed adjacent to the fluid trench and adapted to be fluidly coupled to the fluid trench; a plurality of first channels fluidly coupled to the fluid trench and extending vertically between the fluid jetting chip and a mounting unit adapted to support the fluid jetting chip; and a plurality of second channels fluidly coupled to one or more flow feature channels of the at least one flow feature channel and extending vertically between the fluid jetting chip and the mounting unit, wherein each of the plurality of first channels alternate locations along the fluid trench with each of the plurality of second channels, wherein said each of the plurality of first channels are adapted to supply a priming fluid to the fluid trench, and wherein said each of the plurality of second channels are adapted to drain-out the priming fluid from within the one or more channels of the at least one flow feature channel thereby forming opposite fluid flow directions between the plurality of first channels and the plurality of second channels and forming a plurality of circulation flow paths of fluid between neighboring ones of the plurality of first channels and the plurality of second channels.
