Abstract
Un miembro de pared exterior, tal como la pared de un tubo, que puede ser conectado a la tubería o puede ser integral con ella, tiene una abertura comunicada con el exterior de la tubería. Un miembro interior está colocado fijamente contra el interior del miembro exterior para separar la abertura de la trayectoria del fluido a través de la tubería. El miembro interior tiene una superficie interior que define por lo menos una porción de una cámara interior comunicada con la trayectoria del fluido de la tubería. Los miembros interior y exterior definen un laberinto que tiene un área efectiva en sección transversal, un extremo de entrada para recibir fluído sobrecomprimido de la tubería, y un extremo de descarga comunicado con la abertura de la tubería para emitir fluído. Una pluralidad de canales conectan porciones intermedias del laberinto directamente con la abertura, pasando por alto con ello partes respectivas del laberinto. Una pared elástica, que funciona como una válvula, forma una barrera entre el canal y la cámara interior y es sensible a la presión en la cámara interior para restringir el canal cuando la presión excede a una primera presión predeterminada. Esto impide que el fluido pase por alto una parte del laberinto, aumenta la longitud efectiva del laberinto y reduce con ello el flujo que tiene lugar a la presión más alta.
