Abstract
La presente invención se refiere a una broca para perforar la tierra con un sello de cara rígida mejorado, compensador de presión, comprendiendo dicha broca; un cuerpo; una flecha soportadora proyectante que incluye una base asegurada al cuerpo y una superficie de cojinete, de apoyo rotatorio, generalmente cilíndrica, que se extiende oblicuamente hacia adentro y hacia abajo desde el cuerpo; un cortador, asegurado para girar alrededor de la flecha soportadora, con juego axial y radial debido a los claros, un sistema de lubricación en el cuerpo, que incluye un compensador de presión hidrostática; caracterizada la broca por una ranura de sello de cortador, formada parcialmente por una cara de sello radial, orientada hacia afuera; una ranura de sello de flecha, formada en la base de la flecha soportadora, opuesta a la ranura de sello de cortador, que incluye una superficie circunferencial generalmente cónica; un aro de sello rígido que incluye una cara radial que se acopla selladora y opuestamente a la cara de sello radial de la ranura de sello de cortador, y una superficie circunferencial generalmente cónica, que se opone a y está separada de la superficie cónica de la ranura de sello de flecha; y un aro energizador elástico comprimido entre las superficies cónicas opuestas del aro sellador rígido y la ranura de sello de flecha, con su periferia interna dentro de la superficie de apoyo rotatorio para definir un volumen que permanece esencialmente constante cuando el cortador, el aro rígido y el aro energizador se mueven durante la operación de perforar.
