초록

Apparatus which controllably meters dry powder from a powder supply chamber falling through a vertically disposed axial passageway interconnecting the supply chamber with a mixing chamber therebelow for forming an air-powder mixture therein for transport to a desired site. A tapered plug member is bonded to a bimorph bender comprising a piezoelectric element bonded to each face of a thin, flat, cantilevered metallic beam which is deflectable by a dc bias or driving voltage applied to the bender to cause the tapered plug to penetrate or move within the pa...
