Embodiment Construction

[0075] figure 1The working fluid container 1 according to the invention is shown in a schematic perspective view. The working fluid container 1 has a container wall 10 delimiting a working fluid container interior 13 . It can be seen that in the illustrated embodiment the working fluid container 1 comprises two second reinforcement structures 22 which in the illustrated embodiment are formed as second tensile straps 22 . In this case, the second tensile strap 22 is connected to the outer surface 12 of the container wall 10 facing away from the working fluid container interior 13 . From figure 1 It can also be seen that the second tensile straps 22 are arranged crossing each other, so that the reinforcing fibers of the tensile straps 22 , not shown in the figures, run perpendicularly with respect to each other. Because the reinforcing fibers of the second tensile tape 22 run parallel to the longitudinal extension direction of the second tensile tape 22 . However from figu...

Abstract

The present invention discloses a fuel tank (1) for a motor vehicle, with a tank wall (10) bounding a fuel tank interior (13), characterized by the following features: the fuel tank (1) has a first fiber-reinforced stiffening structure (21) and a second fiber-reinforced stiffening structure (22); the first stiffening structure (21) is connected to an inner surface (11) of the tank wall (10), saidinner surface facing the fuel tank interior (13), and the second stiffening structure (22) is connected to an outer surface (12) of the tank wall (10), said outer surface facing away from the fuel tank interior (13); and the tank wall (10) is arranged at least in sections in a sandwich-like manner between the first stiffening structure (11) and the second stiffening structure (12) such that the first stiffening structure (11) and the second stiffening structure (12) are arranged overlapping at least in sections.

Description

technical field [0001] The invention relates to a working liquid container with a reinforced structure. Background technique [0002] In the sense of the present invention, operating fluid containers made of thermoplastic material are in particular, but not limited to, fuel tanks, wiper tanks, oil tanks, refill fluid tanks or additive tanks of motor vehicles. Containers of the initially mentioned type are usually manufactured by extrusion blow molding, with HDPE (short for high density polyethylene) being particularly suitable for producing extrusion blow molded containers. [0003] In a motor vehicle with an internal combustion engine, when heat is applied to the working fluid container, especially the fuel tank, the working fluid, such as fuel, is also heated, so that the vapor pressure of the working fluid increases and the working fluid container is subjected to a corresponding internal pressure, whereby The fuel tank is deformed. [0004] To ventilate the operating fl...
