    • 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.
    • 用于控制液压阀块中的第一和第二通道之间的流体流动的电磁阀包括阀体。 阀体限定中心轴线,具有穿过其中的中心开口,并且具有适于插入到阀块的孔中的下端。 阀体的上端安装有中空阀罩。 电枢可在阀罩内轴向移动。 弹簧在一个轴向方向上偏置电枢。 闭合元件联接到电枢的下端。 电磁线圈同轴地围绕电枢并且可操作以实现电枢在与一个轴向方向相反的轴向方向上的轴向运动。 阀座构件由阀体的下端承载并且具有在第一阀块通道和第二阀块通道之间提供流体流动的孔口。 阀座构件限定围绕孔的阀座并且与关闭元件配合以选择性地关闭孔。 阀座构件形成为深拉伸部分并且包括管状部分,该管状部分具有限定阀座的一端以及连接到阀体的相对端。
