Abstract
PERFECCIONAMIENTOS EN LA FABRICACION DE MARTILLOS HIDRAULICOS. CARACTERIZADOS POR LA CONSTITUCION DE UN CONJUNTO DE CILINDRO PORTADOR DEL CONJUNTO MOVIL INTERIOR MEDIANTE CAMISAS RECAMBIABLES Y PORTADOR EN EL EXTREMO OPUESTO AL DE ACCIONAMIENTO DEL PUNZON, DE UNA CAMARA DE ACEITE HIDRAULICO SUSCEPTIBLE DE TRANSMITIR Y RECIBIR EL ESFUERZO CON RESPECTO A UN ACUMULADOR DE PRESION GASEOSO ACOPLADO EN EL EXTREMO DEL CUERPO DEL MARTILLO, EL CUAL LLEVA INCORPORADOS DOS CUERPOS DE VALVULAS, EL PRIMER DE LOS CUALES ES PORTADOR DE UNA VALVULA CORREDERA HUECA QUE CONTROLA UN SISTEMA DE TRES PASOS DE COMUNICACION DE ACEITE HIDRAULICO AL CILINDRO PRINCIPAL Y EL SEGUNDO CUERPO DE VALVULAS ES PORTADOR DEL SISTEMA DE VALVULAS DE REGULACION DE PRESION Y SEGURIDAD DE LA CAMARA DE ACEITE HIDRAULICO INTERMEDIA ENTRE LA PARTE POSTERIOR DEL CONJUNTO MOVIL DEL MARTILLO Y LA CAMARA DEL ACUMULADOR DE PRESION, DE GAS.
