Abstract
ARRANJOS DE LIMPEZA E DE CONEXÃO PARA FERRAMENTAS DE PERFURAÇÃO DE PERCUSSÃO. A presente invenção diz respeito a uma ferramenta de perfuração de percussão operada por fluido (1) compreendendo uma luva de desgaste externa (2) compreendendo uma parede substancialmente cilíndrica (3) e tendo superfícies interna (4) e externa (5). A ferramenta também compreende uma broca de percussão (6) tendo uma parte de cabeça (7) e uma parte de retenção de broca (8) e localizada em uma extremidade dianteira (9) da luva de desgaste externa. A ferramenta compreende adicionalmente um pistão deslizante (10) montado para movimento alternado dentro da luva de desgaste externa para golpear a broca de percussão. A ferramenta inclui também um anel de acionamento (11) tendo uma parede substancialmente cilíndrica (12) e compreendendo meios de conexão (13) adaptados para conectar o anel de acionamento a meios de acionamento da ferramenta de perfuração de percussão operada por fluido. Pelo menos um canal de descarga (31) fornece um caminho de fluido para a face de corte da broca para um meio de limpeza. Uma primeira parte (32) do pelo menos um canal de descarga se estende longitudinalmente dentro da parede (3) da luva de desgaste, uma segunda parte (36) do pelo menos um canal de descarga se estende longitudinalmente dentro da parede (12) do anel de acionamento e uma terceira parte (40) do pelo menos um canal de descarga se estende através da parte de cabeça (7) da broca de percussão para a face de corte (43) da broca.
