    • A solenoid valve system, wherein the valve member is provided with a seal member disposed thereabout. The solenoid valve is especially suitable for use with exhaust gas recirculation systems. The seal member is operable to slide axially relative to the valve member, including the stem portion thereof. An optional lubricant is provided between the valve member and the seal member so as to provide a relatively low friction environment therebetween when the valve member is in motion. An optional biasable member, in operable association with the seal member, is provided so as to maintain proper positioning of the seal member, e.g., during operation of the solenoid valve system.
    • 一种电磁阀系统,其中所述阀构件设置有设置在其周围的密封构件。 电磁阀特别适用于废气再循环系统。 密封构件可操作以相对于阀构件轴向滑动,包括其杆部。 在阀构件和密封构件之间设置可选的润滑剂,以便当阀构件运动时在其间提供相对较低的摩擦环境。 提供与密封构件可操作地相关联的可选择的偏置构件,以便例如在电磁阀系统的操作期间保持密封构件的适当定位。
