Abstract

A concealed door closer (10) with an adjustable back check includes a mount (20), a pivot unit (30) mounted to the mount, two damping units (40) connected with the pivot unit, two flow adjusting valves (50a, 50b) mounted in the mount, and a back check adjusting valve (60) mounted in the mount. An external force for opening door drives the pivot unit to rotate so as to actuate the damping units to move. The back check exerting on the door leaf during opening door can be adjusted subject to different conditions by controlling the position of the back check adjusting valve. As soon as the external force exerting on the door leaf for opening the door leaf is released, the door leaf will be gradually closed by the actuation of the damping units, and the speed at which the door closer closes the door can be adjusted by controlling the flow adjusting valves.
