ABSTRACT:
The configuration of an ink inlet through which flows ink into a chamber for expulsion from the chamber by a thermal process is such that a vapor bubble generated by the thermal process to eject ink from the chamber expands to simultaneously occlude the inlet, thereby to separate the ink within the chamber from ink within a channel that is in fluid communication with the inlet. The separation eliminates a liquid path between the chamber and the channel so that substantially no ink is blown back into the channel as the bubble expands, thereby improving the thermal efficiency of the process.
