Abstract: The invention relates to a compensating device suitable for use in railway car transformers. Said compensating device is provided with at least one compensation receptacle (3) which is in fluid-carrying connection (13) with the interior of the housing of a transformer accommodating a fluid volume. The device is also provided with a separating element limiting the fluid volume (21) in the compensation receptacle (3) which, when a change occurs in the fluid volume (21) in the compensation receptacle (3), is subject to a change in position. Said separating element is designed in the form of a roll-over membrane (19). The circumferential edge of said membrane is connected to the side walls (11) of the compensation receptacle (3) at a distance from the bottom (9) of said receptacle in a sealing manner. Said connection is such that the roll-over membrane (19), in its rolled-up state, has a position in which it allows for the largest amount of fluid volume (21) by substantially extending in one plane at a distance from the bottom (9). Said membrane can be rolled-over from this position so as to approach the side walls (11) and bottom (9) in the compensation receptacle (3), thus reducing the fluid volume (21).
