Abstract

UN SISTEMA DE CIRCUITOS HIDRAULICOS PARA UN GATO COMPRENDE UN CIRCUITO DE ENTRADA, UN CIRCUITO DE RETORNO Y UN CIRCUITO DE PROTECCION FRENTE A SOBRECARGAS CON UN CONJUNTO DE CILINDROPISTON (4, 10), UNA VALVULA SECUENCIAL (B), UNA VALVULA DE SEGURIDAD (D) Y UNA VALVULA LIMITADORA (C), EXTENDIENDOSE EL CIRCUITO DE ENTRADA DESDE UN DEPOSITO EXTERIOR (2) A TRAVES DE UNA VALVULA DE RETENCION (A1) HASTA UNA CAMARA DE ACEITE (3) DE UNA BOMBA MANUAL (20), ESTANDO CONECTADA LA CAMARA DE ACEITE (3) A UNA CAMARA DE ACEITE INTERIOR (41) FORMADA EN EL VASTAGO DEL PISTON (4) A TRAVES DE OTRA VALVULA DE RETENCION (A2) PARA FORMAR UN CIRCUITO CERRADO. LA CAMARA DE ACEITE (3) DE LA BOMBA (20) ESTA CONECTADA A UN DEPOSITO INTERIOR (1) EN EL CILINDRO HIDRAULICO (10) A TRAVES DE UNA VALVULA SECUENCIAL (B), Y EL DEPOSITO INTERIOR (1) ESTA CONECTADO AL DEPOSITO EXTERIOR (2) A TRAVES DE UNA VALVULA DE RETENCION (A3). CUANDO LA MAXIMA CAPACIDAD DE EFECTO DE LA CAMARA DE ACEITE (3) DE LA BOMBA (20) ES MAYOR O IGUALQUE LA DE LA CAMARA DE ACEITE INTERIOR (41) DEL VASTAGO DEL PISTON (4), UN SOLO TOQUE DE LA BOMBA (20) PUEDE ELEVAR EL GATO HIDRAULICO HASTA UNA POSICION DE CARGA REQUERIDA EN CONDICIONES DE AUSENCIA DE CARGA O DE CARGA LIGERA.
