Abstract (en)
[origin: US2016177610A1] A door operator includes a housing and at least one linearly guided piston in the housing. A roller carrier is disposed in the piston and includes a rotatably movable supported pressure roller. The piston is formed as a deep drawn structural component and includes a bottom and a circumferential walling. The support and the axial guiding of the roller carrier with a pressure roller within the piston can be realized in a simple and cost effective manner. Furthermore, an aperture is provided in the bottom of the piston, through which the pressure roller protrudes to the outside beyond the bottom of the piston.
