摘要:
An electromagnetic spool valve includes a spool valve, an electromagnetic actuator, and a bracket. The spool valve includes a cylindrical sleeve and a spool. The cylindrical sleeve includes an input/output ports for fluid to flow through. The spool is axially slidable in the sleeve. The electromagnetic actuator is fixed to the spool valve for axially driving the spool. The bracket is welded to the electromagnetic actuator. The spool valve is disposed in a fixing member and is fixed thereto by a tightening member tightening the bracket welded to the yoke to the fixing member. Either the bracket or the electromagnetic actuator includes a stopper contact portion for contacting a part of the other to prevent the electromagnetic spool valve from being removed from the sleeve insertion hole.
