Abstract

Se describen varias modalidades de una válvula de exhalación y una máscara facial de filtrado que incluye tal válvula de exhalación. La válvula de exhalación puede incluir un asiento de válvula y una aleta de válvula dispuesta sobre una superficie de sellado y un orificio del asiento de válvula. La aleta de válvula está adaptada para sellarse contra la superficie de sellado del asiento de válvula cuando la válvula de exhalación está dispuesta en una configuración cerrada de tal manera que se evita que el fluido fluya a través del asiento de válvula. El orificio del asiento de válvula puede incluir una forma sustancialmente circular en un plano definido por una primera superficie principal del asiento de válvula. Además, la superficie de sellado puede circunscribir el orificio y puede incluir una forma sustancialmente no circular en el plano definido por la primera superficie principal del asiento de válvula.
