Abstract
An electromagnetic valve for use in controlling fluid flow between first and second passageways in a hydraulic valve block includes a valve body. The valve body defines a central axis, has a central opening therethrough, and has a lower end adapted to be inserted into a bore of the valve block. A hollow valve dome is attached to an upper end of the valve body. An armature is axially moveable within the valve dome. A spring biases the armature in one axial direction. A closing element is coupled to a lower end of the armature. An electromagnetic coil coaxially surrounds the armature and is operable to effect axial movement of the armature in an axial direction opposite the one axial direction. A valve seat member is carried by a lower end of the valve body and has an orifice providing fluid flow between the first and second valve block passageways. The valve seat member defines a valve seat that surrounds the orifice and cooperates with the closing element for selectively closing the orifice. The valve seat member is formed as a deep drawn part and includes a tubular portion having one end defining a valve seat, and an opposite end connected to the valve body.
