Actuator with fail safe mode

An actuator with a predetermined failure mode comprises two carriers 1, 2 which are each moveable in a common direction. A detent 18, 22 is engageable to couple the carriers to move in unison. An electrically operated actuating device 28 causes extension of a toggle linkage to operate the detent, an...

description	An actuator with a predetermined failure mode comprises two carriers 1, 2 which are each moveable in a common direction. A detent 18, 22 is engageable to couple the carriers to move in unison. An electrically operated actuating device 28 causes extension of a toggle linkage to operate the detent, and collapses the toggle linkage when de-energised. A prime mover 5 operates the first carrier 1 and a spring 8 returns the second carrier 2 on release of the detent. The detent comprises a pivoted arm 18 disposed on the first carrier and positioned to engage a part 22 of the second carrier. The toggle linkage comprises a pair of relatively pivoted links 23, 24 connected between a pivot 26 on the first carrier and a pivot 27 on the arm 18.
