    Abstract: A door closer unit (100) including a cylindrical housing (10) with a partition (14) axially extending inside and having a first liquid path; a moving body (20) with a movable barrier (24) dividing the interior of the housing into first and second chambers, and a rotational shaft (21) having an upper end extending upward; a door return spring (30) applying a recovering force to the door in a direction opposite to the direction when the moving body's rotational shaft (21) or housing (10) rotates in one direction; a high-viscosity liquid filling in the housing; a control check valve for opening a second liquid path when the door is opened, and closing the second liquid path when the door is closed; a cover (40) rotatably supporting the rotational shaft (21) of the moving body (20) and sealing the upper portion of the housing (10); a speed controller (19) regulating the amount of the liquid when the door is opened or closed, thus controlling the speed of the door; and a door stopper (29) for stopping the door when the door reaches to a predetermined rotating angle including the door's initial position.
