Abstract

"VáLVULA DE CONTROLE E UM MéTODO PARA UM DISPOSITIVO DE PERCUSSãO COM UM CICLO DE TRABALHO ENVOLVENDO VáRIOS MOMENTOS DE ACOPLAMENTO". A invenção refere-se a uma válvula de controle, a um dispositivo de percussão e a um método para controlar um ciclo de trabalho de um dispositivo de percussão. Um dispositivo de percussão (1) para rompimento de rocha inclui um elemento de impacto (8) controlado por uma válvula de controle (2). A válvula de controle inclui um elemento de controle (5) disposto para controlar canais (7b) que levam a uma superfície sob pressão de trabalho (9) do elemento de impacto (8). O elemento de controle, durante um ciclo de trabalho da válvula de controle, é disposto para abrir e fechar canais de pressurização em vários momentos de conexão, de tal forma que durante cada ciclo de trabalho da válvula, vários pulsos de impacto são produzidos.
