Abstract: A door operator for operating a door includes a housing, an output shaft with a cam disc, an opening piston guided in the housing, which piston, on a first side, bears against the cam disc, an energy accumulator acting upon the opening piston for storing a closing energy for the door, and a damping piston guided in a cylindrically shaped hollow space of a cylinder element, and which piston, on a second side, bears against the cam disc, wherein the cylinder element is firmly connected to the opening piston.

Abstract: A regulating valve, which is attachable in particular in a bore, executed with a female thread, of a hydraulic door closer. The regulating valve has a body adjoined by a regulating section and has a thread located at the body. In order to provide a regulating valve which has a simple configuration, and in which an unwanted, independent adjusting of the regulating valve is excluded during operation, at least one prominence is provided in a reception for an insert part. The prominence engages in a surface of an insert part such that, upon an axial rotational movement of the regulating valve, the insert part is moved in rotational direction. The insert part cooperates in a clamping and a sealing manner with the bore or the female thread of the door closer. In one embodiment, the prominences act as a cam for the insert part.
