HYDRAULIC SPECIFICATIONS SPECIFICHE IDRAULICHE Parallel circuit Circuito Parallelo When the spool is operated it intercepts the switch gallery by diverting the flow of oil to service port A or B. If two or more spools are actuated at the same time, the oil will power the service port that has the lower load by selecting the path with the least resistance; by throtting the spools, the flow of oil can be divided between two or more service ports. Il cursore quando viene azionato, intercetta il canale di libera circolazione deviando il flusso d’olio agli utilizzi A o B. Se due o più cursori vengono...
