摘要：
The invention relates to door closers, particularly a door closer control device that regulates the flow of a pressure medium controlling the function of a door closer. A control device according to the invention includes a support part with a collar that serves as a second support for the control device on the door closer body in addition to the support in the guiding part. This second support holds the control device in place within the pressure medium flow without any rocking or swaying movement, which would hamper the door closing speed.
