The invention relates to a housing which is composed of two housing halves ( 1 a, 1 b ) that form a bottom ( 5 ) and a lid ( 6 ) and an intervening section ( 7 ). According to the invention, sections of the walls of the two housing halves ( 1 a , 1 b ) are configured as respective peripheral rims ( 10, 11 ) which are joined to each other while overlapping, thereby increasing the wall thickness in the area of the rims ( 10, 11 ). The rims ( 10, 11 ) thus contribute to the wall thickness required to impart to the housing the necessary stability.
1. A fuel filter housing for use in a motor vehicle, comprising:
two housing halves which form a bottom, a lid, and a side wall section located between the bottom and lid one of the housing halves defining an outlet and the other of the housing halves defining an input connectable to a fuel line for receiving fuel, each housing half having a wall thickness which is sufficient for a designated strength and comprising ribs configured to hold and mount a fuel filter inside the housing, the side wall section being formed by overlapping side wall portions of the housing halves,
wherein each of the side wall portions of the housing halves comprises a peripheral edge in the region of the overlapping side wall portions,
wherein the respective peripheral edges do not abut each other over the side wall section located between the bottom and lid, and
wherein the wall thickness formed by the overlapped peripheral edges of the housing halves is greater than the wall thickness of either of the respective housing halves and has essentially the same wall strength as the bottom and the lid, wherein the overlapping side wall portions of the housing halves overlap over the entire length of the side wall section.
2. The fuel filter housing as claimed in claim 1 , wherein the side wall section is cylindrical.
3. The fuel filter housing as claimed in claim 1 , wherein the bottom and the lid are dome shaped.
4. The fuel filter housing as claimed in claim 1 , wherein the bottom and lid are curved.
5. The fuel filter housing as claimed in claim 1 , wherein the peripheral edges extend with a constant wall thickness into the respective bottom and lid.
6. The fuel filter housing as claimed in claim 1 , wherein the peripheral edges are designed with a wall thickness which is reduced toward the open end of the respective housing half.
7. The fuel filter housing as claimed in claim 1 , wherein at least one integrally formed raised peripheral collar is arranged between the respective peripheral edges.
8. The fuel filter housing as claimed in claim 1 , wherein an integrally formed raised peripheral collar is arranged on each of the respective peripheral edges and the respective peripheral collars are disposed between the respective peripheral edges.
9. The fuel filter housing as claimed in claim 8 , wherein each of the peripheral collars has step only on a side which faces an open end of the respective housing half.
10. The fuel filter housing as claimed in claim 7 , wherein the housing halves are joined by means of welding, in particular laser welding or ultrasonic welding in the region of the peripheral collar.
11. The fuel filter housing as claimed in claim 1 , wherein the housing halves are joined by means of bonding.
12. The fuel filter housing as claimed in claim 1 , wherein one of the housing halves comprises a part of a lid for closing an opening in a fuel tank.
13. The fuel filter housing as claimed in claim 1 , wherein the wall strength of the bottom, the lid and the overlapping peripheral edges is sufficient to withstand a maximum permanent load in the range of 8-10 bar.
14. The fuel filter housing as claimed in claim 1 , wherein the ribs are disposed on both the bottom and the lid.
