  • Fi ltervoriquesen the above type are known in the art. They are used, for example, in fuel systems for internal combustion engines, in order to protect sensitive components, in particular injection systems, from being impaired by water components entrained in the fuel. In the effort to achieve energy efficiency and good exhaust gas values in diesel engines, the injection systems have recently undergone further technical development. Instead of simple mechanical injection systems, common-rail injection systems are used, which operate as high-pressure systems with pressures of 2500 bar and more. In such high-pressure systems, free water components, in addition to other contaminants, have a particularly disadvantageous effect on the operational safety of the injection system. At the same time, the recent changes in diesel fuel to hamper water abstraction. The main reason for this is the increasing proportion of so-called biodiesel and the reduction of the sulfur content.

  • An advantage consists in the simplified production in that the spun-spray layer can optionally be applied to an already glued hollow cylinder of the filter material 39 and so with a filter body already manufactured a filter element without water separation and even with applied Spun- spray Fiber material can produce a filter element with water separation.
  • Another advantage of this flow direction is that the flow velocity on the outside of the filter element is significantly smaller by the much larger area than in a flow from outside to inside. This in turn means that the drops formed can be better separated due to their now lower kinetic energy.
  • an additional barrier such as the hydrophobized fabric 43, on the outside of the filter with respect to the surface can make much larger than can be the case with a flow from the outside inwards. It is thus generated a very low hydraulic load, whereby drops are deposited improved.
