Abstract
UNA VALVULA QUE CONSTA DE UNA PRIMERA CAPA RIGIDA CON UNA PRIMERA SUPERFICIE SUSTANCIALMENTE PLANAR, Y UNA SEGUNDA CAPA RIGIDA CON UNA SEGUNDA SUPERFICIE SUSTANCIALMENTE PLANAR DISPUESTA HACIA LA PRIMERA, Y UNA TERCERA SUPERFICIE SUSTANCIALMENTE PLANAR OPUESTA A LA SEGUNDA, Y UNA CAPA FLEXIBLE POSICIONADA ENTRE LAS SUPERFICIES PRIMERA Y SEGUNDA. UNA CAMARA DE VALVULA ESTA DEMARCADA POR UNA SUPERFICIE CONCAVA EN LA PRIMERA SUPERFICIE SUSTANCIALMENTE PLANAR, Y UNA SUPERFICIE DE LA CAPA FLEXIBLE Y AL MENOS UN PRIMER CONDUCTO DE FLUIDO EN LA PRIMERA CAPA RIGIDA QUE SE ABRE EN LA CAMARA DE VALVULA EN LA SUPERFICIE CONCAVA PARA APLICAR ALTERNATIVAMENTE UN VACIO Y UNA PRESION A LA MISMA. UNA CAMARA DE FLUIDO ESTA DEMARCADA POR OTRA SUPERFICIE DE LA CAPA FLEXIBLE Y UNA SUPERFICIE CONCAVO-CONVEXA EN LA SEGUNDA SUPERFICIE SUSTANCIALMENTE PLANAR, QUE INCLUYE UNA PARTE CONVEXA CIRCULAR Y UNA PARTE CONCAVA EXTERNA ANULAR Y CONCENTRICA. AL MENOS DOS SEGUNDOS CONDUCTOS DE FLUIDO EN LA SEGUNDA CAPA RIGIDASE ABREN EN LA CAMARA DE VALVULA EN LA SUPERFICIE CONVEXA. CUANDO SE APLICA UN VACIO A LA CAMARA DE VALVULA, LA CAPA FLEXIBLE SE FLEXIONA PARA ESPACIAR LA OTRA SUPERFICIE DE LA CAPA FLEXIBLE ALEJANDOLA DE LA SUPERFICIE CONCAVO-CONVEXA PARA PERMITIR LA COMUNICACION DE ENTRE AL MENOS DOS SEGUNDOS CONDUCTOS DE FLUIDO; Y CUANDO SE APLICA PRESION A LA CAMARA DE VALVULA, LA CAPA FLEXIBLE SE FLEXIONA PARA DISPONER LA OTRA SUPERFICIE DE LA CAPA FLEXIBLE SOBRE LA SUPERFICIE CONCAVO-CONVEXA PARA EVITAR LA COMUNICACION ENTRE AL MENOS LOS DOS CONDUCTOS PRIMEROS Y SEGUNDOS DE FLUIDO.
