Electromagnetic valve

An electromagnetic valve for use in controlling fluid flow between first and second passageways in a hydraulic valve block, comprising:

• a valve body defining a central axis and having a central opening therethrough, the valve body having a lower end adapted to be inserted into a bore of the valve block and provided with a lower cylindrical opening;
• an armature axially moveable within the valve body;
• a spring for biasing the armature in one axial direction;
• a closing element carried by a lower end of the armature;
• an electromagnetic coil coaxially surrounding the armature and operable to effect axial movement of the armature in an axial direction opposite the one direction;
• and
• a valve seat member carried by the lower end of the valve body and having an orifice providing fluid flow between the first and second valve block passageways, the valve seat member defining a valve seat surrounding the orifice and cooperating with the closing element for selectively closing the orifice, and wherein the valve seat member includes a cylindrical tubular portion positioned within the lower cylindrical opening of the valve body,
• characterized in that:
• the lower cylindrical opening of the valve body is provided with a stop surface at the upper end of thereof, the valve seat is defined at an outside upper end of the valve seat member, the cylindrical tubular portion extends outwardly and downwardly from the valve seat and is sealingly engaged with the lower cylindrical opening of the valve body, and an upper part of the cylindrical tubular portion of the valve seat member includes a radially outwardly extending flange between the valve seat and the portion of the cylindrical tubular portion that is sealingly engaged with the lower cylindrical opening of the valve body, the flange engageable with the stop surface for limiting downward movement of the valve seat member relative to the valve body.
