Abstract: A rim well with integrated flange made of fiber composite as well as to a method for manufacturing same. The flange is formed by inwardly directed protuberances of fiber layers of the rim well, wherein the fiber layers transition to the flange from the rim well without interruption of the fibers. The manufacture is carried out by depositing fiber material on a mold, which corresponds to the contour of the rim well and has a radially circumferential or segmented groove. The fibers are deposited such that the fibers of at least one fiber layer have protuberances directed into the groove. A multipart mold, which makes it possible to reduce the width of the groove and thus a deformation of the protuberances, is preferably used.

Abstract: A fuel system for an internal combustion engine includes at least one first fuel pump and a pressure region into which the fuel pump pumps and which communicates with an elastic volume reservoir. The elastic volume reservoir has a characteristic pressure/volume curve, which is defined by at least two points. It is proposed that a first point is defined by a first volume at a first pressure that is somewhat greater than a vapor pressure of the fuel at ambient temperature, and that a second point is defined by a second volume and a second pressure in the pressure region that corresponds to a maximum pressure; the difference between the first and second volumes corresponds at least approximately and at least to a value by which the volume of the fuel in the pressure region decreases upon cooling down from a maximum temperature to ambient temperature.
