Claims

[Scope of utility model registration request]

In an electromagnetic control valve spool valve consisting of a spool valve section attached to a device and a solenoid section installed in the air that operates the spool valve section,
An oil spill passage that communicates with the oil discharge side of the spool valve part at least during excitation operation is formed in the housing of the spool valve part and the linear solenoid part, and the oil spill passage opens on the outer peripheral surface of the housing on the linear solenoid part side. Electromagnetic control spool valve.
