The valve solenoids can be divided into two kinds of AC and DC in voltage by the different power, the wet solenoids is composed by the coil, rectangular framework , the pusher, the armature and magnetically permeable sleeve , the coil is disposed within a rectangular frame , the two together, with a plastic or steal encapsulation of the package through the coil center and framework on both sides of a through hole for the sleeve on a magnetically permeable sleeve, permeable sleeve contains the armature, the magnetically permeable sleeve mounted on the valve body of the solenoids valve screwed permeable casing bore and electromagnetic the the
valve return oil interlinked, so the armature infiltration in the oil of the system , which is called the wet
solenoid valve .
Around the coil generates a magnetic field of the
solenoid valves, the magnetic field around the the rectangular ferromagnetic channel and the internal coil of the armature coil strengthened, turned on the moment the current in the wet armature coil , still part of the movable armature of the coil outside, the current generated by the armature of the magnetic field will be inhaled, impinging contact with the spool pusher , so that the electromagnetic
switching valve commutated with spool commutation , the armature will be fully into the coil , the coil magnetic field is completely distributed in the ferromagnetic channel.
Iron is a good magnetic conductor and around the armature and the plunger oil is permeable wet principle of operation of the electromagnet is resident in the magnetic pull-in armature, thereby reducing the core portion of the coil causing a great reluctance gap. As the hydraulic directional spool valve solenoids' armature is moved, the slit is gradually reduced, increasing the thrust of the solenoid output when the electromagnetic force of the armature online circle larger than the electromagnetic force when the line outside of the circle.
