Abstract

"PERFURADORA PARA ROCHAS ENXAGUADA". Perfuradora para rochas (1) com uma cabeça de perfuração (4) em forma de panela, enxaguada com água, móvel em relação à haste de perfuração (3), de maneira axialmente limitada, um invólucro interno da cabeça de perfuração (5), sendo que a haste de perfuração (3) apresenta um êmbolo(6), alocado ao invólucro interno da cabeça de perfuração (5), para a alteração de volume de um espaço de enchimento (8) o qual pode ser enchido com líquido através de pelo menos uma abertura estreita de corrente dinâmica (7a, 7b, 7c, 7d)."RINSE ROCK DRILL". Rock drill (1) with a pan-rinsing, water-rinsed drill head (4) movable relative to the drill rod (3), axially limited, an inner shell of the drill head (5), wherein the drill rod (3) has a plunger (6) allocated to the inner casing of the drill head (5) for changing the volume of a filling space (8) which may be filled with liquid through at least one narrow dynamic current aperture (7a, 7b, 7c, 7d).
