摘要： An electrical lock for a moving part prevents the part from moving unless a device controlled by the part is in a safe mode. The invention may find a use in many different environments. The specific example here described is a set of reverse thruster doors on a jet engine. The lock prevents a throttle from applying or removing power unless the reverse thruster doors are properly set for such application or removal of power. The lock is removed when the doors reach full deployment or retraction, respectively, which is appropriate for the direction in which said throttle is moved. These functions are provided under the control of a single solenoid.

摘要： A solenoid has a multistage telescoping plunger which together produce a single stroke. Each plunger stage has a separate air gap individually associated therewith. As the first air gap closes responsive to movement of a first telescoping plunger stage, a portion of the stator becomes magnetically saturated; however, magnetic material has moved with the first plunger stage in order to bridge the saturated position which switches the flux path to a second air gap via a second of the telescoping plunger stages. An advantage is that the solenoid has a long stroke with a high pulling force on both the initial and the final ends of a continuous stroke formed by the separate movements of the first and second plunger stages.
