Abstract: An automatic door closer includes: a casing having a primary and a secondary cylinder juxtapositionally formed in the casing for resiliently holding two pistons in the two cylinders filled with a hydraulic oil and partitioned with a wall formed with a main hole and a throttling hole for communicating the two cylinders, wherein each piston is normally urged by a tensioning spring towards the two holes in the casing, whereby upon an opening of the door, an upper piston is retracted to compress an upper spring in the primary cylinder to suck oil from the secondary cylinder to the primary cylinder and also to extend the lower piston and tension the lower spring for accelerating a door opening operation and saving the door-opening force; and a positioning device provided for temporarily keeping the door at its opened state by locking a positioning pin in a recess formed in the upper piston.
