11. When the solenoid is disengaged a spring takes over valve actuation duties. 12. Both Volvo and Ford use wet clutches and hydraulic actuation . 13. This actuation gathered around sixty castellers, who unloaded several basic constructions. 14. Pneumatic actuation is used to keep all tubing free of contamination . ]] 15. Therefore the process of actuation should not jeopardize the structure's strength. 16. Roll control was by differential actuation of the wing-fan exit louvers. 17. The system also allows manual actuation by the operator. 18. Magnetic actuation can either be used for actuating 1D or 2D MEMS mirrors. 19. Moreover, mechanical advantage is possible by use of electrostatic-pneumatic actuation . 20. Repeated actuation of the rotary solenoid advances the snap-switch forward one position.
