Abstract

Mecanismo de percusión de muelle neumático para un martillo de percusión y/o martillo perforador, con - un émbolo de accionamiento (1) movible axialmente en sentido de vaivén con un casquillo de guía (1a), un fondo del émbolo (2) y una suspensión del émbolo (3); - un émbolo de percusión (17) movible axialmente en sentido de vaivén en el casquillo de guía (1a); - un espacio hueco (19) constituido entre el émbolo de accionamiento (1) y el émbolo de percusión (17) y que rodea un muelle neumático; y con - un tubo de guía (16) que guía el casquillo de guía (1a), caracterizado porque - en el casquillo de guía (1a) se ha previsto al menos una ranura de compensación neumática (5) que presenta una longitud, que es mayor que la longitud axial de una superficie de contacto del émbolo de percusión (17) con el casquillo de guía (1a), cuando el émbolo de percusión (17) se encuentra totalmente recogido en el casquillo de guía (1a), - el tubo de guía (16) cubre la ranura de compensación neumática (5)en su lado exterior radial; y - el espacio hueco (19) es comunicable a través de la ranura de compensación neumática (5) con un lado frontal (1b) delantero del émbolo de accionamiento (1).
