Abstract
Martillo de fondo que tiene un tambor de martillo (17) con una broca (14) sujeta en un extremo del martillo. Un piston (10) se mueve alternativamente dentro del tambor del martillo (17) e impacta repetidamente contra la broca (14). Un dispositivo de control del fluido provoca el movimiento alternativo de dicho piston (10) por medio del control de fluido a alta presion, donde parte del dispositivo de control de fluido incluye: multiples canales alargados (22) en la superficie interna de dicho tambor del martillo (17) espaciados radialmente alrededor de dicha superficie interna, una superficie de sellado circunferencial (12) en el extremo delantero de dicho piston (10) o en direccion al mismo, que coopera con dichos canales (22) para ayudar a controlar dicho flujo de fluido, existiendo un huelgo entre cualquier porcion de dicho piston anterior a dicha superficie de sellado (12) y la superficie interna de dicho tambor del martillo.Bottom hammer that has a hammer drum (17) with a drill bit (14) held at one end of the hammer. A piston (10) moves alternately inside the hammer drum (17) and repeatedly hits the drill bit (14). A fluid control device causes the reciprocating movement of said piston (10) by means of high pressure fluid control, where part of the fluid control device includes: multiple elongated channels (22) on the inner surface of said drum of the hammer (17) radially spaced around said internal surface, a circumferential sealing surface (12) at the front end of said piston (10) or in the direction thereof, which cooperates with said channels (22) to help control said flow of fluid, there is a gap between any portion of said piston anterior to said sealing surface (12) and the internal surface of said hammer drum.
