Abstract

Una microválvula de retención (1100) para controlar el flujo de un líquido, que comprende un asiento de la válvula (210) compuesto por un material sustrato; una tapa de la válvula (220) dispuesta sobre el asiento de la válvula (210), un espacio definido entre el asiento de la válvula y la tapa de la válvula; y un elemento flotante (230) que se mueve en el espacio entre el asiento de la válvula (210) y la tapa de la válvula (220) mediante la aplicación de presión sobre el elemento flotante por el líquido para controlar pasivamente el flujo del líquido a través del asiento de la válvula (210) y la tapa de la válvula (220); caracterizada porque el asiento de la válvula (210) comprende un asiento de la válvula multinivel que tiene una primera superficie (212) a un primer nivel y una segunda superficie (1102) a un segundo nivel por debajo del primer nivel, estando dispuesta la tapa de la válvula (220) en la primera superficie (212).
