How does floor spring work?

Floor springs operate using what we call a CAM action mechanism. When the door is opened, regardless of in which direction, the bottom arm, which is fixed to the door, rotates the CAM spindle. This, in turn, rotates the CAM itself. The CAM is connected to the piston and, when it's rotated, pulls the piston head.
