<p>The first improvement described relates to the gasket (20) between the ink reservoir (15), with its nozzle plate (61) attached, and the drop generator body (11) that encloses the dynamic pressure transducer (13). If this gasket (20) is formed of very soft material, having a durometer value in the order of 60, then it is only necessary to clamp the plate (61) to the drop generator body (11) with sufficient torque to seat and seal the ink reservoir (15) to prevent ink leakage. The second improvement described requires a small space (59, 60) between each crystal (52) in a piezoelectric transducer (15) and the washer (58) of acoustic-absorbing material, and the third improvement involves the support rod (56) for these crystals. The support rod (56) should fit with sufficient frictional force to retain the crystals (52) in a preset position, avoiding all unnecessary extra loading of the crystals.</p> |
