Abstract

APARATO QUE COMPRENDE UN EMBOLO DE IMPACTO (1) ACCIONADO HIDRAULICAMENTE DE MANERA ALTERNA POR UN FLUIDO NO COMPRESIBLE EN EL INTERIOR DE UN CILINDRO, Y QUE HACE PERCUTIR UNA HERRAMIENTA (60), DEL TIPO EN EL QUE EL EMBOLO SE DESLIZA EN UN CILINDRO QUE LLEVA DOS PORTADAS DE EMBOLO CONCENTRICAS DE SECCIONES DIFERENTES, SIENDO LA SITUADA DEL LADO DE LA HERRAMIENTA DE SECCION INFERIOR A LA MAS ALEJADA DE LA HERRAMIENTA, DELIMITANDO EL EMBOLO Y EL CILINDRO DOS CAMARAS ANTAGONISTAS, UNA CAMARA INFERIOR ANULAR (7) Y UNA CAMARA SUPERIOR DE MAYOR SECCION. SEGUN LA INVENCION, EL INTERIOR DE LA CAMARA SUPERIOR (3) ESTA PERMANENTEMENTE A UNA PRESION AJUSTADA, DE VALOR INTERMEDIO ENTRE LAS PRESIONES DE ENTRADA O ALTA PRESION Y DE SALIDA O BAJA PRESION, Y LA CAMARA INFERIOR ANULAR (7) ESTA CONECTADA ALTERNATIVAMENTE POR UN DISTRIBUIDOR (6) AL CIRCUITO DE ALIMENTACION DE ALTA PRESION DURANTE LA FASE DE SUBIDA DEL EMBOLO (1) Y A LA CAMARA SUPERIOR (3) DURANTE LA FASE DE BAJADA ACELERADA DEL EMBOLO (1).
