Definitions
- the invention relates to a device for delivering fuel according to the preamble of the main claim.
- a device for delivering fuel from DE 198 56 298 Cl is already known, with a suction jet pump which has a drive line and a mixing channel, a nozzle-like constriction with a nozzle opening being provided in a first section of the drive line facing the mixing channel, and the The drive line is fluidly connected to the mixing channel via the nozzle opening.
- the mixing channel is formed on a storage container and the nozzle-like constriction as a separate part on the
- the suction jet pump sucks fuel through a suction opening from a storage container into a suction space.
- the fuel drawn in tends due to the dynamics of the fuel entering the intake chamber which is not parallel to the driving jet direction
- the nozzle Due to tolerances between the nozzle and the drive line, the nozzle must be installed in the
- Drive line are checked so that it is aligned in the direction of the mixing channel, the driving jet runs in the direction of the mixing channel and not at an angle to it, so that the driving jet does not hit the wall of the mixing channel after a certain distance and lies there.
- the device according to the invention with the characterizing features of the main claim has the advantage that the device according to the invention is improved in a simple manner by a higher delivery rate is achieved with the same amount of propellant jet that the propulsion jet is prevented from being applied to the housing wall.
- the fuel flowing into the suction jet pump is guided in a flow-guiding manner in such a way that the drive jet experiences little or no deflection in the direction of the wall of the mixing channel.
- the at least one web connects the partial section of the drive line to the mixing channel in one piece, since the nozzle of the drive line is oriented in a defined manner in this way to the mixing channel. After assembly the device therefore eliminates the additional test of whether the nozzle is correctly aligned.
- the at least one web is flat or curved in the direction of flow.
- the at least one web extends from the subsection of the drive line in the axial and radial direction to the mixing channel.
- the at least one web projects beyond the nozzle opening in the direction of the mixing channel.
- annular inlet opening is provided in the mixing channel between the first section of the drive line and the mixing channel, since the nozzle can thus flow completely around and the fuel sucked in by the driving jet enters the mixing channel at least approximately parallel to the driving jet. This at least greatly reduces the deflection of the driving jet.
- the wall thickness of the at least one web when viewed in the axial direction with respect to an axis of the mixing channel, is small compared to the cross section of the inlet opening of the mixing channel, since the fuel sucked in by the propellant jet is least swirled in this way. It is also advantageous if the first section of the Treilo line with the nozzle-like constriction and the mixing channel are inserted into a housing of the suction jet pump, since in this way the device can be installed very easily.

- the first subsection 2.1 of the drive line 2 and the mixing channel 3 are arranged, for example, in the direction of the tank bottom 10, this also being referred to as the lying arrangement of the suction jet pump 1.
- an arrangement of the first subsection 2.1 of the drive line 2 and the mixing channel 3 which is perpendicular or also referred to as standing with respect to the tank bottom 10 is also possible.
- a second subsection 2.2 of the drive line 2 is connected, for example via a pressure control valve 11, to a pressure line 12 which runs from a delivery unit 15 to an internal combustion engine 16 and supplies it with fuel.

- a main filter 19 is provided in the pressure line 12, for example , which filters out fine dirt particles contained in the fuel.
- the drive line 2 branches off from the pressure line 12, for example downstream of the main filter 19, and supplies the suction jet pump 1 with fuel when the pressure control valve 11 is open.
- the pressure control valve 11 opens when the pressure in the pressure line 12 exceeds a predetermined value and leaves excess fuel from the pressure line 12 via the drive line 2 with the first and second subsection 2.1.2.2, the nozzle 5 and the mixing channel 3 of the suction jet pump 1 back in flow the storage tank 8.
- the suction jet pump 1 sucks fuel from the reservoir 9 in a known manner, the Fuel reaches an intake chamber 23 of the suction jet pump 1 via an intake opening 22.
- the suction jet pump 1 can, however, also be expressly fed via a return line, the excess
- the suction jet pump 1 can be connected directly to the pressure line 12 both upstream and downstream of the main filter 19, the pressure of the pressure line 12 being reduced, for example, by a throttle.
- the fuel of the propellant line 2 passes through the nozzle opening 5 of the nozzle 4 as a so-called propellant jet into the intake chamber 23, the propellant jet passing through the intake chamber 23 from the nozzle 5 and reaching into the mixing duct 3 adjoining the intake chamber 23.
- the driving jet takes fuel from the suction chamber 23 and / or the mixing channel 3 in the flow direction, so that a negative pressure is created in the suction chamber 23, which allows fuel to flow from the reservoir 9 through the suction opening 22 into the suction chamber 23.
- the fuel of the driving jet and the entrained fuel of the intake space 23 and / or the mixing channel 3 flow via the mixing channel 3 and an outlet opening 24 of the mixing channel 3 into the storage container 8.
- the first section 2.1 of the drive line 2 extends, for example, into the suction space 23 and can extend into an inlet area 25 at the beginning of the mixing channel 3 or beyond.
- the fuel flowing from the intake chamber 23 in the direction of the mixing duct 3 flows around the first subsection 2.1 of the drive line 2 with the nozzle 4 and enters the mixing duct 3 through an annular inlet opening 26 between the mixing duct 3 and the first subsection 2.1 of the drive line 2. Due to the flow around the first section 2.1 of the drive line 2, the flow enters the mixing channel 3 almost parallel to the drive jet, so that the flow forces deflecting the drive jet are low.
- At least one web 27 is provided between the wall of the first section 2.1 of the drive line 2 and the wall of the mixing duct 3, which web 27 enters through the annular inlet opening 26
- the entire driving jet surface can be used for entraining fuel from the intake chamber 23, so that the delivery rate of the suction jet pump 1 is improved with the same amount of driving jet.

Due to the design of the device with a plurality of webs 27, there is a mechanically more stable connection between the first subsection 2.1 with the nozzle 4 and the nozzle Mixing channel 3. In addition, the flow is guided in the direction of the mixing channel 3 even better in this way than with only one web 27.
