Abstract
CIRCUITO HIDRAULICO PARA UN MOTOR QUE MUEVE UNA CARGA. EL CIRCUITO HIDRAULICO SIRVE PARA LA SOLICITACION ALTERNATIVA DE UN MOTOR QUE MUEVE UNA CARGA (22) Y DEBE DETENERSE INMEDIATAMENTE EN EL CASO DE QUE APAREZCA UNA ROTURA DE LA TUBERIA O MOVERSE DE UNA MANERA CONTROLADA SIN NINGUNA ACCION DESDE EL EXTERIOR. PARA ELLO EL CIRCUITO PRESENTA ADEMAS UNA BOMBA (24) PARA LIQUIDO A PRESION UNA VALVULA DE MANDO (28) Y DOS TUBERIAS (30 32) QUE UNEN LA VALVULA DE MANDO (28) CON EL MOTOR CONFIGURADO COMO CILINDRO (12) SOLICITABLE POR AMBOS LADOS QUE SIRVEN DEPENDIENDO DE LA POSICION DE LA VALVULA DE MANDO (28) COMO TUBERIA DE ALIMENTACION O COMO TUBERIA DE RETORNO Y QUE PRESENTAN SENDAS VALVULAS (34 48) CONTROLADAS POR PRESION PILOTO.
