    摘要： A system or apparatus that in one implementation includes an electromagnetic valve having an actuator rod with a first coil and a second coil positioned at different longitudinal locations on the actuator rod and being situated electrically parallel to one another in an electrical circuit. The electromagnetic valve is constructed to induce a first voltage in the second coil when the electromagnetic valve is in the open position and to induce in the second coil a second voltage lower than the first voltage when the electromagnetic valve is in the closed position. A switch changeable between a first position and a second position is located in the electrical circuit. When the switch is in the first position the electrical circuit is configured to allow current from a power source to be delivered to the second coil. When the switch is in the second position the electrical circuit is configured to not allow current from a power source to be delivered to the second coil. A control device situated in series with the second coil in the electrical circuit is adapted to detect the open or closed position of the first electromagnetic valve based on the induced voltage of the second coil. The control device is adapted to act upon the switch to change it between the first and second positions. In one implementation, upon detecting that the electromagnetic valve is in the closed position, the control device is configured to act upon the switch to cause it to assume the first position.

    摘要翻译： 在一个实施方式中的系统或装置包括具有致动器杆的电磁阀，所述致动器杆具有第一线圈和位于致动器杆上的不同纵向位置处的第二线圈，并且在电路中彼此电并联。 电磁阀被构造成当电磁阀处于打开位置时在第二线圈中产生第一电压，并且当电磁阀处于关闭位置时，使第二线圈中的第二电压低于第一电压。 在第一位置和第二位置之间可切换的开关位于电路中。 当开关处于第一位置时，电路被配置成允许来自电源的电流被输送到第二线圈。 当开关处于第二位置时，电路被配置为不允许来自电源的电流被传送到第二线圈。 与电路中的第二线圈串联设置的控制装置适于基于第二线圈的感应电压来检测第一电磁阀的打开或关闭位置。 控制装置适于作用在开关上以在第一和第二位置之间改变它。 在一个实施方式中，当检测到电磁阀处于关闭位置时，控制装置被配置为作用于开关以使其处于第一位置。
