The invention relates to a door closer, in particular a pivoting door closer, with a free-swing function, comprising a door closer housing, an output shaft that can be connected to a door, a piston assembly which is connected to the output shaft and which is guided in the door closer housing, a closing spring, a piston rod arranged for connecting the piston assembly to the closing spring, a free-swing arrangement which is designed to enable a translational movement of the piston assembly in a decoupled manner from the closing spring when the closing spring is blocked and which is designed as a displacement coupling that transmits pressure forces exclusively between the closing spring and the piston assembly. The door closer also comprises a hydraulic blocking chamber designed to block the closing spring.
