Abstract

1. Un conjunto de ampolla elastomérica para recibir y distribuir un fluido a presión , que comprendiendo una caja tubular; un obturador fijado en un extremo de la caja; un pistón axialmente desplazable dentro de tal caja y dispuesto en la zona opuesta a la del obturador; una ampolla elastomérica tubular alojada en la caja y destinada a recibir y contener el fluido a presión, cuyos extremos se unen herméticamente al obturador y pistón, respectivamente; caracterizado porque la referida ampolla elastomérica va montada entre dos soportes tubulares enfrentados axialmente, los cuales emergen de la cara interna del obturador y del pistón, respectivamente, de tal modo que en la posición de reposo, previa a la introducción del fluido, el diámetro interior de la ampolla queda rellenado por los soportes cuyos extremos enfrentados contactan entre sí, pudiendo resistir las compresiones axiales entre tales extremos enfrentados sin ofrecer sustancialmente resistencia a la expansión y contracción axiales de la propia ampolla, en orden a poderse mantener espaciados tales extremos de los soportes cuando se desinfla la ampolla, así como a poderse separar axialmente durante el inflamiento y juntarse de nuevo durante el desinflado de la ampolla; habiéndose previsto un tabique divisorio perforable y soltable en correspondencia con el pistón, a través del cual es susceptible de producirse el llenado y vaciado de la ampolla por medio de la perforación axial producida por una aguja. 2. Un conjunto de ampolla elastomérica para recibir y distribuir un fluido a presión, según reivindicación 1, caracterizado porque el pistón y soporte tubular que emerge axialmente del mismo, están afectados de un orificio a través del cual pasa la aguja, quedando ésta alojada en el paso longitudinal que define el orificio del soporte tubular. 3. Un conjunto de ampolla elastomérica para recibir y distribuir un fluido a presión, según reivindicaciones 1 y 2, caracterizado porque incluye además medios de control de flujo para controlar la liberación o salida del fluido desde la ampolla al exterior. 4. Un conjunto de ampolla elastomérica para recibir y distribuir un fluido a presión.
