Abstract

UN CIRCUITO HIDRAULICO DE ACEITE PARA UNA PALA HIDRAULICA EN LA QUE UNA OPERACION COMNBINADA DE, POR EJEMPLO, GIRAR Y ELEVAR, PUEDE REALIZARSE CON FACILIDAD Y SUAVEMENTE SIN UNA HABILIDAD ESPECIAL EN LA OPERACION. EL CIRCUITO COMPRENDE JUEGOS PRIMERO Y SEGUNDO DE VALVULAS HIDRAULICAS (A, B), ADAPTADO CADA UNO A RECIBIR UN SUMINISTRO DE FLUIDO A PRESION, PROCEDENTE DE UNA BOMBA (2, 3) INDIVIDUAL DE MANO, Y PASAR EL FLUIDO A PRESION A LOS RESPECTIVOS ACTUADORES PRIMERO (13) Y SEGUNDO (14) HIDRAULICOS, CONTROLANDO ESTOS DOS ACTUADORES DIFERENTES OPERACIONES DE LA MAQUINA HIDRAULICA; EL CITADO SEGUNDO JUEGO (B) DE VALVULAS HIDRAULICAS, ADEMAS DE PASAR FLUIDO A PRESION A SU SEGUNDO ACTUADOR (14) ASOCIADO, TAMBIEN ES CONTROLABLE PARA PASAR FLUIDO A PRESION ADICIONAL AL PRIMER ACTUADOR (13); UN MEDIO (10) QUE ESTA INSTALADO EN UN CONDUCTO (22, 26), QUE COMUNICA EL SEGUNDO JUEGO (B) DE VALVULAS HIDRAULICAS CON EL CITADO PRIMER ACTUADOR (13) PARA AJUSTAR EL SUMINISTRO DE FLUIDO A PRESION ADICIONAL AL PRIMER ACTUADOR (13), EN RESPUESTA A UNA SEÑAL (PO); Y UN CONTROLADOR (17) PARA AJUSTAR LA SEÑAL (PO) Y AJUSTAR EL CITADO MEDIO (10), Y, CONSECUENTEMENTE, EL SUMINISTRO ADICIONAL DE FLUIDO A PRESION AL CITADO PRIMER ACTUADOR (13) PARA, MEDIANTE ELLO, CAMBIAR LA VELOCIDAD RELATIVA DE LAS DIFERENTES OPERACIONES CONTROLADAS POR LOS DOS ACTUADORES (13, 14).
