摘要： A door closer comprises a piston cooperating with a rotating pinion. Upon rotation of the pinion in the door opening direction, the piston moves toward the second end of the housing forcing fluid from a second variable volume chamber through a passage to a first variable volume chamber and compressing a spring assembly for storing energy. The spring assembly urges the piston toward the first end of the housing for forcing fluid from the first variable volume chamber to the second variable volume chamber and rotating the pinion in the door closing direction. A controller controls the position of a valve in the passage based on the sensed angular position of a door and the position of the valve for determining the amount of hydraulic fluid flowing through the valve.
