Abstract

"DISPOSITIVO DE PERCUSSãO ROTATIVA PARA PERFURAçãO DIRECIONAL EM ROCHA, E, FERRAMENTA DE RETROALARGADOR PARA USO NA PERFURAçãO DE ROCHAS". Um dispositivo de percussão com percussão rotativa para perfuração direcional controlada em rocha compreende uma parte de corpo girante (15) substancialmente cilíndrica alojando um martelo de percussão, e uma cabeça troncónica (2) excentricamente montada sobre a frente da parte de corpo. A face de diâmetro mínimo (3) da cabeça está adjacente à parte de corpo. O eixo geométrico (6) da cabeça é paralela a porém desviada do eixo geométrico (5) do corpo. A face frontal (4) da cabeça é em forma de talhadeira e compreende pelo menos um plano oblíquo (11) se inclinando para a frente na mesma direção do desvio do eixo geométrico da cabeça em relação ao eixo geométrico do corpo.
