A hydraulically damped door closer is described which has a relatively weak closer spring (3c) and stronger back-up closer springs (3a, 3b). If, after a predetermined time period, the door does not arrive in the closed position under the effect of the closer spring (3c), the back-up closer springs (3a, 3b) are connected for the closing. Their connection is therefore controlled by way of a time function element, which represents a simple and, at the same time, reliable control.
