Abstract

Un dispositivo de desplazamiento de fluido para definir y desplazar un desplazamiento volumétrico sustancialmente constante, que actúa como respuesta a diferenciales de presión de fluido incluyendo dicho dispositivo un cuerpo hueco de volumen fijo provisto de superficies lisas opuestas cóncavas en u interior y de forma idéntica, que presentan superficies sustancialmente iguales: un diafragma flexible, no elástico, permanentemente formado que presenta y mantiene sustancialmente la misma forma y la misma superficie que cada una de la superficies cóncavas, estando sujeta de manera fija, la periferia del diafragma entre las periferias de las superficies cóncavas originando el tamaño, forma, deformación permanente no elasticidad y sujeción fija de dicho diafragma su montaje para que pueda desplazarse entre y contra las superficies cóncavas definiendo el movimiento del diafragma desde una superficie hasta la otra superficie el volumen fijo está consistentemente logrado en cada desplazamiento de movimiento recíproco de dicho diafragma
