Abstract

Un aparato de impacto o martillo operable por fluido, que comprende un cuerpo que tiene un anima alargada que se extiende en el y un pistón de martillo movible axialmente dentro de dicha anima para formar dentro de ella una cámara de volumen variable, caracterizado por una cámara de escape destinada a comunicación de fluido con un conducto de fluido de escape, un paso para comunicación de fluido entre dicha cámara de volumen variable y dicha cámara de escape, una válvula que puede funcionar selectivamente para abrir y cerrar dicho paso para controlar la circulación de fluido a través de el, y un conjunto de bomba para retirar fluido hidráulico desde dicha cámara de escape solo cuando esta abierto dicho paso.
