| description | The present invention relates to a combination-type hydraulic actuator capable of minimizing the effort and costs required for maintenance and being highly responsive. The combination-type hydraulic actuator comprises: a hydraulic passage including a driving motor, and first and second fluid transfer units through which fluid flows and which are formed on one side and the other side thereof and communicate with the outside; a gear pump unit including a pair of transfer gears provided between the first fluid transfer units to be rotated by the driving motor and changing the direction of fluid in a rotation direction; and a cylinder device including a piston and a cylinder provided so that the piston is vertically movable and including an accommodating space communicating with the first fluid transfer unit above the stroke range of the piston and communicating with the second fluid transfer unit below the stroke range of the piston. Fluid is circulated by the driving force of the driving motor, and the piston is operated.
