Abstract: A method for drying a fluid film, which is applied to a surface of a substrate and includes a vaporizable liquid, includes following steps: transporting the substrate on a transport surface of a transport device along a transport direction through a drying device; vaporizing the liquid by way of a heat source having a heating surface, wherein the heating surface is disposed at a distance of 0.1 mm to 5.0 mm opposite to a surface of the substrate; and removing a vaporized liquid in a direction of the heat source.

Abstract: The invention relates to a fuel injection system, in particular a common rail injection system, in which fuel is conducted from a distributor pipe via high-pressure lines to injectors, by means of which the fuel can be injected during an injection cycle with a number of injection pulses, wherein each of the high-pressure lines is provided with at least one damping device for damping pressure pulsations. In order to simplify the production of the damping device, the damping device has a pipe, in which a core that is held at a distance via spacers so as to form an annular gap is provided.

Abstract: The invention relates to a method for drying a fluid film (F), which is applied to a surface of a substrate (3) and includes a vaporizable liquid, comprising the following steps: transporting the substrate (3) on a transport surface (6) of a transport device (5) along a transport direction (T) through a drying device (7); vaporizing the liquid by way of a heat source (13) having a heating surface (G), wherein the heating surface (G) is disposed at a distance (?G) of 0.1 mm to 5.0 mm opposite the substrate surface; and removing the vaporized liquid in the direction of the heat source (13).

Abstract: The invention relates to a coating tool for applying a fluid film onto a substrate, wherein disposed upstream of a slot nozzle (1) for producing a fluid film, said nozzle extending substantially across the entirety of a first width (B1) of the coating tool in unbroken fashion, is a distribution space (7) for distributing the fluid over a second width (B2) of the slot nozzle (1), wherein at least one channel (6) for feeding fluid is provided upstream of the distribution space (7), said channel having a third width (B3), and wherein the third width (B3) is smaller than the second width (B2). To avoid an uneven throughput of material across the width of the slot, it is proposed according to the invention that a plurality of feed channels (9) be disposed in the distribution space (7), said channels having a cross sectional area that increases in the direction of flow (S).
