Submersible electromechanical actuator

摘要

An electromechanical actuator includes a housing 102 and a magnetic core 126 movably disposed in the housing. An impervious chamber containing the stator is defined between the housing wall and can 114, the chamber being filled with a dielectric fluid. Pressure balancing is provide by bellows 152. The actuator may be rotary and arranged to surround the stator - 126 fig 6 or may be linear - 205 fig 5. Fluid tight electrical connection is provided through bulkhead 108.
