ABSTRACT:
A linear fluid actuator having two pistons and two cylinder chambers in tandem to provide redundancy when supplied from independent pressure sources. The actuator is balanced in that the actuator output force is equal in extend or retract positions. The two cylinder chambers are made from separate housings to prevent crack propagation between the chambers and dual piston rod construction is provided to enhance redundancy.
