In a pressure-maintaining device for a fuel supply system of an internal combustion engine (1) of a motor vehicle, a pressure reservoir (5) is arranged in a supply line (7) leading to the internal combustion engine (1). The pressure reservior (5) has a pressure chamber (13), which is bounded by a movable wall (14) that is pretensioned by a compression spring (15). The position of the movable wall (14) is registered by a displacement transducer (18) and forwarded to a regulating device (12). The regulating device (12) regulates the rotational speed of a fuel pump (3) as a function of the position of the movable wall (14).

[ What is claimed is:] [1.]1. A pressure-maintaining device for a fuel supply system of an internal combustion engine of a motor vehicle, having a pressure reservoir connected to a supply line between a fuel pump and the internal combustion engine, the pressure reservoir having a pressure chamber, a pretensioned, movable wall in order to bound a volume of fuel in the pressure chamber and means for registering the position of the movable wall, it being possible for the fuel pump to be variably regulated by a regulating device as a function of the position of the movable wall, wherein the regulating device is designed to produce a central position of the movable wall.
