Abstract

MéTODO PARA CONTROLAR DISPOSITIVO DE PERCUSSãO OPERADO POR FLUIDO DE PRESSãO, E DISPOSITIVO DE PERCUSSãO. A invenção se refere a um método para controlar um dispositivo de percussão operado por fluido de pressão compreendendo uma câmara de operação (3) para fluido de pressão, e, na câmara de operação (3), um pistão de transmissão (4) instalado movelmente em relação a esta, de modo a capacitar uma ferramenta (5) instalada no dispositivo de percussão a ser pressionada contra um material a ser rompido de modo a gerar um pulso de tensão, e a um dispositivo de percussão. O método compreende ajustar o comprimento do pulso de tensão pelo ajuste do tempo durante o qual a pressão influencia o pistão de transmissão (4) . O dispositivo de percussão compreende um elemento de ajuste (14) e meios de ajuste para ajustar o tempo de influência da pressão do fluido de pressão sendo alimentado, via uma válvula de controle (8), e influenciando o pistão de transmissão (4)
