Abstract

Un dispositivo de restricción de la circulación de un fluido para proporcionar una disipación y controlada de la energía de circulación del fluido, que comprende una pluralidad de partes rígidas de acoplamiento por contacto dispuestas a través de la trayectoria de dicha circulación del fluido, y aberturas de circulación del fluido formadas a través de la superficie de cada una de dichas partes y espaciadas a través de ella, con lo cual cada una de dichas aberturas de circulación del fluido actúa como cámara de expansión para el fluido que circula a su través, siendo cada una de las partes de acoplamiento de dimensiones uniformes en todo el grueso de la parte y estando dispuestas para solapar al menos una de las aberturas de circulación del fluido de una parte contigua para formar un orificio de restricción para la comunicación de circulación entre dichas aberturas.
