Abstract

UN SISTEMA DE CONTROL DE VALVULA DE UN MOTOR ELECTROHIDRAULICO EN UN MOTOR MULTI-VALVULAS, EN EL QUE LAS VALVULAS DE ENTRADA (O SALIDA) (10) EN CADA CILINDRO SE CONTROLAN HIDRAULICAMENTE MEDIANTE UN CONJUNTO DE VALVULAS HIDRAULICAS (64,68). CADA VALVULA DEL MOTOR (10) INCLUYE UN PISTON DE VALVULA (26) SOMETIDO A UNA PRESION DE FLUIDO QUE ACTUA SOBRE LAS SUPERFICIES EN LOS DOS EXTREMOS, CON EL VOLUMEN (27) EN UN EXTREMO CONECTADO A UNA FUENTE DE FLUIDO DE ALTA PRESION (40) MIENTRAS QUE EL VOLUMEN EN EL OTRO EXTREMO (25) SE CONECTA SELECTIVAMENTE A UNA FUENTE DE FLUIDO A ALTA PRESION (40) Y UNA FUENTE DE FLUIDO DE BAJA PRESION (42), Y DESCONECTADO DE CADA UNA MEDIANTE UNA ACCION DE LAS VALVULAS HIDRAULICAS (64,68). CADA GRUPO DE VALVULAS DEL MOTOR CORRESPONDIENTES (10) SE ENCUENTRA UNIDO HIDRAULICAMENTE ENTRE SI Y PUEDE MOVERSE EN UNISONO. EXISTEN MUELLES DE COMPENSACION (80) QUE ESTAN UNIDOS OPERATIVAMENTE A CADA PISTON DE VALVULA (26), PARA COMPENSAR LAS TOLERANCIAS DE FABRICACION Y OTROS FACTORES, COMPENSANDO EL MOVIMIENTO DE LAS VALVULAS DEL MOTOR (10) MIENTRAS SE ABREN Y CIERRAN.
