ABSTRACT:
A relatively thin but powerful linear power actuator particular adapted for the individual control of a plurality of closely stacked adjacent hydraulic valves. Each of the two disclosed embodiments include a reversible DC motor coupled to reduction gearing which drives a pivotable drive plate. Pivotally coupled to the drive plate is a driven plate from which a linear output shaft extends. The two plates may be connected together by a remotely operable solenoid coupler for motor control of the linear output shaft, or decoupled for manual control of the output shaft independently of the motor control.
