Abstract
Patente de Invenção: <B>"APARELHO E MéTODO PARA UTILIZAR BOLHA COMO VáLVULA VIRTUAL NO MICROINJETOR PARA EJETAR FLUIDO"<D>. Um aparelho e método para formar uma bolha dentro de um microcanal de um microinjetor para funcionar como um mecanismo de válvula entre a câmara e o tubo de distribuição, que proporciona uma alta resistência ao líquido saindo da câmara através do tubo de distribuição durante a ejeção do fluido através de um orifício e que também proporciona uma baixa resistência ao reabastecimento de líquido para dentro da câmara após a ejeção do fluido e do desmoronamento da bolha. Isto efetivamente minimiza a linha cruzada entre as câmaras adjacentes e aumenta a freq³ência de injeção do microinjetor. A formação de uma segunda bolha dentro da câmara funde-se com uma primeira bolha formada entre a câmara e o tubo de distribuição para abruptamente terminar a ejeção do fluido, por meio disso eliminando as gotículas satélite.
