    • An electromagnetically actuator is disclosed having an electromagnet, a core element, the core element having a normally biased initial spaced apart first position distal from the electromagnet when the electromagnet is off and a second stop position proximal from the electromagnet when the electromagnet is on, a first resilient member adapted to bias said core element in the normally biased first position, and a second resilient member adapted to bias the electromagnet away from the core. The first resilient member is more resilient than the second resilient member. Therefore, the core approaches the electromagnet when the electromagnet is on until the core reaches the fixed stop position, and the electromagnet subsequently approaches the core to the fixed stop position. The actuator may further include an adjustment member that engages the electromagnet so as to control the pressure of the electromagnet against the second resilient member, whereby the axial position of the electromagnet is controlled.
    • 公开了一种电磁致动器,其具有电磁体,芯元件,当电磁铁断开时,该芯元件具有远离电磁体的正常偏置的初始间隔开的第一位置,以及当电磁铁接通时靠近电磁体的第二停止位置, 第一弹性构件,其适于在所述正常偏置的第一位置偏置所述芯体元件;以及第二弹性构件,其适于使所述电磁体偏离所述芯。 第一弹性构件比第二弹性构件更具弹性。 因此,当电磁铁开启直到磁芯到达固定停止位置时,磁芯接近电磁铁,电磁铁随后接近磁芯到固定停止位置。 致动器还可以包括调节构件,其接合电磁体,以便控制电磁体抵靠第二弹性构件的压力,从而控制电磁体的轴向位置。
