Abstract
A brake cylinder, especially for rail vehicles, with a simple-acting linkage regulator for maintaining a uniform play between the brake surfaces. A nut that is disposed upon a threaded spindle is connected with first coupling surfaces that cooperate with second coupling surfaces disposed on the piston of the control or operating cylinder. A coupling element that is provided with the first coupling surfaces is further provided with a centrally disposed pin that is guided in the piston of the cylinder. A spring or other member that is under pressure is clamped onto the pin, with this member being secured in such a way that it cannot shift parallel to the axis of the pin nor can it rotate with the pin.
