Abstract (en)
The invention is related to a door closer (10) comprising a first housing (11), a second housing (12), a transmission element (13), a first piston (15) and a second piston (16) solidly attached by a rod (17). The first piston (15) is arranged in the first housing (11) to receive the linear movement of the transmission element (13) and the second piston (16) is arranged in the second housing (12). A resilient element (18) is arranged to provide a return force against the first piston (15). The second housing (12) comprises at least a first valve (1) and a second valve (2), both valves being located in the first half (23), the second valve (2) being located closer to the first end (21) than the first valve (1). The first valve (1) is configured to allow only fluid outlet from the stroke zone (20) to the exterior of the second piston (16) and the second valve (2) is configured to allow only fluid inlet inside the stroke zone (20) from the exterior of the second piston (16). The invention also provides a door assembly (100) comprising such a door closer (10).
