| 摘要 |
The invention relates to a pressure-accumulating brake cylinder (1), comprising a housing (2) in which a pressure accumulator piston (4) runs, dividing an internal chamber of the housing (2) into a pressure accumulation chamber (22) and a pressure chamber (21), a spring arrangement (221), arranged in the pressure accumulation chamber (22) and tensioning the pressure accumulator piston (4) in the direction of the pressure chamber (21) and a mechanical emergency release device (5), for the mechanical emergency release of the pressure accumulating brake cylinder (1). A linear displacement of the pressure accumulating piston (1) is thus possible, by means of the mechanical emergency release device (5), against the tension of the spring arrangement (221), with a threaded spindle (51), acting as operating device, rigidly fixed, in the axial direction, to the housing (2) and the emergency release device (5) furthermore comprises an indicator device (54) which displays the position of the pressure accumulating piston (4), relative to the operating device. It is thus possible to have a reliable display of whether the pressure accumulating brake cylinder has been released in an emergency or not, even for an emergency release device with a threaded spindle which is not unscrewed externally.
