Abstract

SE DESCRIBE UNA PRENSA HIDRAULICA QUE COMPRENDE UNA PRIMERA CAMARA (2/10) PARA LA COMPRESION DEL LIQUIDO HIDRAULICO, UNA SEGUNDA CAMARA DE TRABAJO, LOS PISTONES RESPECTIVOS (2/11, 2/15), UN CONDUCTO SELLADO (2/4) QUE CONECTA ENTRE SI LOS VOLUMENES INTERIORES DE LAS DOS CAMARAS MENCIONADAS, UN ELEMENTO DE EMPUJE (2/12) ADECUADO PARA EJERCER PRESION SOBRE EL PISTON DE LA CITADA PRIMERA CAMARA, UNA ABERTURA (2/16) QUE PERMITE QUE EL VOLUMEN QUE CONTIENE EL LIQUIDO HIDRAULICO SE PONGA EN COMUNICACION CON EL AMBIENTE EXTERIOR, UN MEDIO DE CIERRE (2/18) ADECUADO PARA CERRAR DICHA ABERTURA Y VINCULADO A UN MEDIO DE TRANSMISION DE MOVIMIENTO (2/13) DESPLAZABLE A DISTINTAS POSICIONES DE MANERA QUE EL CITADO MEDIO DE CIERRE SE DESPLACE A POSICIONES RESPECTIVAS EN LAS QUE CIERRA Y DESCUBRE COMPLETAMENTE DICHA ABERTURA. LA MISMA ABERTURA EXISTE EN UNA PARTE QUE SE EXTIENDE DESDE EL CITADO CONDUCTO SELLADO QUE CONECTA ENTRE SI LOS VOLUMENES INTERIORES DE LAS DOS CAMARAS MENCIONADAS Y EN LA CABEZA DEL PISTON DE LA CAMARA DE COMPRESION DEL LIQUIDO HIDRAULICO.
