A spring-type brake cylinder that includes a compression spring, a pressure chamber, a dividing wall disposed between the compression spring and the pressure chamber, a piston having an inner wall and a bottom, and a nut disposed inside the piston and configured to be held on a release bolt. A support structure is disposed inside the piston and configured to abut against the nut while the release bolt is screwed into the nut. The piston comprises a first retaining structure and a second retaining structure, the first retaining structure configured to hold the support structure in an assembly position and the second retaining structure configured to hold the support structure in a drive position. The support structure is moveable from the assembly position to the drive position by a movement of the nut relative to the piston. |

1. A spring-type brake cylinder, comprising:
a compression spring; a pressure chamber having a wall with an opening therein; a dividing wall disposed between the compression spring and the pressure chamber; a piston having an inner wall and a bottom, the piston being disposed in the pressure chamber and operable to extend through the opening in the wall of the pressure chamber; and a nut disposed inside the piston and configured to be held on a release bolt, wherein the piston includes a guide configured to guide the nut such that the nut cannot be rotated in the piston and such that the nut is moveable along a longitudinal direction of the piston, wherein a support structure is disposed inside the piston and configured to abut against the nut while the release bolt is screwed into the nut, wherein the piston comprises a first retaining structure and a second retaining structure, the first retaining structure configured to hold the support structure in an assembly position and the second retaining structure configured to hold the support structure in a drive position, wherein the drive position is closer to the bottom than the assembly position, and wherein the support structure is moveable from the assembly position to the drive position by a movement of the nut relative to the piston. |
