PURPOSE:To force bubbles out of an electromagnetic spool valve by reciprocating a spool regardless of primary action of the electromagnetic spool valve. CONSTITUTION:A controller for controlling an electromagnetic spool valve for controlling a damping force of a shock absorber is set to vibrate a spool (S5) regardless of damping control when a car velocity V is a set value alpha or less (S1 and S2), and if an engine rotation number N is a set value beta or more (S3 and S4). With the spool vibrated, bubbles generated in actuation oil around the spool are forced out. |
