Definitions

• the invention relates to a fuel flow module according to the preamble of the main claim.
• the fuel delivery module according to the invention with the characterizing features of the main claim has the advantage that damage to the recording during assembly is avoided by the tank flange facing the end of the guide rod has a holding cooperating with the receptacle bead and a constriction behind it.
• the inventive construction the pressing of the guide rod takes place only in the region of the bead.
• the bead is disc-shaped, nail-head-shaped, bead-like, collar-shaped, annular, flange-shaped or collar-shaped.
• the receptacle of the tank flange in the press-in direction seen a guide portion and then one compared to the guide portion narrowed Holding portion, wherein between the bead and the guide portion a clearance fit and between the bead and the holding portion is provided a press fit.
• This has the advantage that the press length is shorter and thereby the risk of cracking is reduced.
• the holding portion of the tank flange has longitudinal ribs and the bead is pressed in each case against the longitudinal ribs. This has the advantage that the necessary press-in force is reduced and thus the mounting device is cheaper.
• each end of the guide rod can be pressed into the receptacle is very advantageous.
• the guide rods 4 must therefore not be fed to the assembly machines in the manufacturing process.
• FIG. 1 shows in section a simplified fuel disposal module and FIG. 2 shows a partial view of the fuel storage module according to FIG.
• FIG. 1 shows in section a simplified fuel flow module shown.
• the fuel disposal module 1 has a tank flange 2 and a storage pot 3, which is connected to the tank flange 2 via at least one, for example two guide rods 4 and axially movable relative to the tank flange 2 in the direction of the guide rods 4.
• a delivery unit 5 may be provided, which sucks fuel from the storage tank 3 and pressure increases via a pressure line 6 to an internal combustion engine 7 calls.
• the fuel disposal module 1 is provided in a fuel tank 10, which has a mounting opening 11, through which the fuel delivery module 1 can be inserted into the fuel tank 10.
• the tank flange 2 is arranged in the Montageöffhung 11 and closes it.
• the fuel delivery module 1 has at least one spring element 8 which presses the storage pot 3 in a direction away from the tank flange 2. In this way, the storage pot 3 is pressed against a bottom 12 of the fuel tank 10.
• the spring element 8 is for example a Coil spring, which is arranged on the guide rod 4, is supported on the tank flange 2 and acts with its other end on the storage cup 3.
• the example cylindrical guide rod 4 is pressed with one end in a receptacle 15 of the tank flange 2 and extends from the receptacle 15 in the direction of storage pot 3. Die
• Recording 15 is a depression on the tank flange 2, for example a blind hole.
• the guide rod 4 is provided in a guide 16, which is an axial movement of the storage pot
• a stop 17 is designed to limit the axial movement, for example a locking ring or a locking washer.
• the guide rod 4 is made of metal or plastic.
• FIG. 2 shows a view of the press connection between the tank flange and the guide rod according to Fig.1.
• the bead 20 is an annular thickening of the guide rod 4, which is arranged for example on the tank flange 2 facing the end of the guide rod 4.
• the bead 20 is designed in the manner of a nail head, bead-like, collar-shaped, disc-shaped, annular, flange-shaped or collar-shaped.
• the receptacle 15 facing edges of the bead 20 are executed rounded.
• the guide rod 4 has a main section 4.1.
• the diameter of the bead 20 is less than or equal to the diameter of the main section 4.1.
• the constriction 21 has a diameter which is smaller than the diameter of the main section 4.1 and that of the bead 20.
• the transition from the main section 4.1 to the constriction 21 may be stepped or continuous, for example conical.
• the receptacle 15 of the tank flange 2 as seen in the press-in direction, has a guide section 15.1 and subsequently a holding section which is narrowed relative to the guide section 15.1 15.2 on. Between the bead 20 and the guide portion 15.1 of the receptacle 15 is a clearance fit and between the bead 20 and the holding portion 15.2 of the receptacle 15 is provided a press fit.
• the holding section 15.2 is shorter with respect to the longitudinal extent than the guide section 15.1.
• the bead 20 is easily inserted into the receptacle 15 and is pressed only in the region of the short holding portion 15.2 over a short distance.
• the guide rod 4 is inserted into the receptacle 15 up to a bottom or a stop 15.3.
• the constriction 21 is formed so long in the axial direction, that after the mounting of the guide rod 4 in the receptacle 15 from the bead 20 into the area of
• constriction of the holding portion 15.2 is achieved by distributed over the circumference of the receptacle 15, spaced apart longitudinal ribs 22.
• Longitudinal ribs 22 may of course also be provided a shoulder which has a constant diameter over the entire circumference, which is smaller than that of the guide section 15.1.
• the bead 20 is pressed against the holding portion 15.2, for example against the longitudinal ribs 22.
• the bead 20 presses elastically into the material of the receptacle 15.
• the two ends of the guide rod 4 are formed substantially mirror-symmetrical or uniform.
• the guide rod 4 has therefore at both ends in each case a single bead 20 and a respective underlying constriction 21.
• the mirror-symmetrical design of the guide rod 4 facilitates the manufacture of the fuel delivery module, since both ends are suitable to be pressed into the receptacle 15.
• the guide rods 4 must therefore not be fed to the assembly machines in the manufacturing process.
• a grounding plug 25 is provided, which electrically contacts the guide rod 4 and is connected to an electrical ground to charge electrical charges from the
• the grounding plug 25 extends with a leg in a space between the guide rod 4 and the guide portion 15.1 of the receptacle 15th
