Abstract
La presente descripción se refiere a un ensamblaje de barrenado de fondo (11) activado mediante fluido bajo presión. Un entubado alargado (15) que tiene un extremo axialmente posterior (15a) y un extremo axialmente delantero, un pistón encendido por fluido (13) colocado de manera movible en el interior del entubado (15), una cámara de funcionamiento superior (27) en un lado superior del pistón (13), una cámara de funcionamiento inferior (28) en un lado inferior del pistón (13), una pluralidad de pasajes de fluido (52) para alimentación y descarga de fluido presurizado hacia dentro y hacia fuera de las cámaras de funcionamiento para la generación de movimiento recíproco para el pistón, una barrena (14) capaz de conectarse al extremo axialmente delantero (15b) del entubado (15) y provista con un yunque (26) que se orienta hacia el pistón (13) para la recepción de los impactos del pistón (13) y un sustituto de conducción anular (18) que rodea al menos una porción de un mango (17) y que coopera con la barrena (14) a fin de formar pasajes de fluido que se extienden de manera longitudinal a lo largo del mango (17). El sustituto de conducción (18) comprende un surco curvo cóncavo que se extiende circunferencialmente en el sustituto de conducción, formando una cámara (21) para recolección del fluido proveniente del escape del martillo y redistribución del volumen del fluido recolectado a partir de los canales (48) formados entre estrías complementarias (43) del sustituto de conducción (18) y las estrías (42) de la barrena (14) hacia orificios de descarga (24) colocados en la barrena (14).
