    • An actuated atomizer is adapted for spray cooling or other applications wherein a well-developed, homogeneous and generally conical spray mist is required. The actuated atomizer includes an outer shell formed by an inner ring; an outer ring; an actuator insert and a cap. A nozzle framework is positioned within the actuator insert. A base of the nozzle framework defines swirl inlets, a swirl chamber and a swirl chamber. A nozzle insert defines a center inlet and feed ports. A spool is positioned within the coil housing, and carries the coil windings having a number of turns calculated to result in a magnetic field of sufficient strength to overcome the bias of the spring. A plunger moves in response to the magnetic field of the windings. A stop prevents the pintle from being withdrawn excessively. A pintle, positioned by the plunger, moves between first and second positions. In the first position, the head of the pintle blocks the discharge passage of the nozzle framework, thereby preventing the atomizer from discharging fluid. In the second position, the pintle is withdrawn from the swirl chamber, allowing the atomizer to release atomized fluid. A spring biases the pintle to block the discharge passage. The strength of the spring is overcome, however, by the magnetic field created by the windings positioned on the spool, which withdraws the plunger into the spool and further compresses the spring.
    • 致动的雾化器适用于喷雾冷却或其他应用,其中需要发达,均匀和大体上呈锥形的喷雾。 致动雾化器包括由内环形成的外壳; 外圈; 致动器插件和盖。 喷嘴框架定位在致动器插入件内。 喷嘴框架的基部限定了涡流入口,涡流室和涡流室。 喷嘴插入件限定了中心入口和进料口。 线轴被定位在线圈壳体内,并且承载具有多个匝数的线圈绕组,其被计算得到足够强度的磁场以克服弹簧的偏压。 柱塞响应于绕组的磁场而移动。 止挡可以防止枢纽过度撤回。 由柱塞定位的枢轴在第一和第二位置之间移动。 在第一位置,枢栓的头部堵塞喷嘴框架的排出通道,从而防止雾化器排出流体。 在第二位置,枢轴从涡流室排出,允许雾化器释放雾化的流体。 弹簧偏压枢栓以阻止排放通道。 然而,通过由位于线轴上的绕组产生的磁场来克服弹簧的强度,其将柱塞缩回到线轴中并进一步压缩弹簧。
