Abstract
A door closer assembly includes a central shaft rotatingly mounted in an outer housing and which passes through at least one brake pad. One or more wedges are slidingly mounted on the central shaft by means of a fastener. The wedges, upon tightening of the fastener, wedge against an inclined surface, which forces the wedges downwards and applies a downwards force that causes a friction-enhanced surface to rub against the at least one brake pad.
