Beschreibung
Zusammenfassung:	An electromagnetic-mechanical locking device applied to a subsurface safety valve comprising an electromagnetic-mechanical coupler formed electromagnet (4), ferromagnetic bulkhead (5) in solidarity to the mobile part (6), actuated by spring (9), in addition to locking element (7), and when activated, the electromagnet (4) creates a magnetic field that attracts the ferromagnetic bulkhead (5), along with the mobile part (6), moving this set towards the electromagnet (4), and compressing the locking element (7). During the movement, the mobile part (6) shifts the locking element (7) to the locking position, until it reaches its coupling on the flow tube (3), where it is maintained with compression locking element (7), configuring a trigger device. When the power supplied to the electromagnet (4) ceases, the electromagnetic attraction force of the ferromagnetic bulkhead (5) is cancelled, and the locking element (7), until then retracted, is distended, causing the return of the mobile part (6) to initial position.
