Abstract

In an electromagnetic valve, a stator assembly includes an electrically energizable coil and a thin-walled core which receives and reciprocally supports an armature. The thin-walled core has a closed end and an open end, the open end being in fluid communication with a fluid flow passage within a valve member. The valve member reciprocates with the armature to control flow rate in the flow passage. A flange integral with the thin-walled core extends about the open end. A washer receives the thin-walled core and abuts the flange. The flange and the washer are received in a recess in the valve body and are permanently and sealingly fixed therein by a swaged joint in the valve body.
