Abstract
Disclosed herein is a power control apparatus. A piston partitions a hydraulic chamber of a cylinder body unit into a first hydraulic chamber and a second hydraulic chamber. A screw shaft unit passes through the piston and is threadedly coupled to the piston. The first hydraulic chamber and the second hydraulic chamber are directly connected to each other by a single hydraulic chamber connection pipe. A valve unit is provided on the hydraulic chamber connection pipe. Force of rotating the screw shaft unit, required to move the piston, is controlled by adjusting the degree of opening of the hydraulic chamber connection pipe.
