Definitions
- the invention relates to a suction jet pump according to the preamble of the main claim.
- suction jet pump from DE 103 03 390 Al known, with a drive line, which opens via a jet outlet in a suction chamber, wherein the suction chamber has a cooperating with a valve member Ansaugöffhung, can be sucked through the fluid into the suction chamber.
- the valve member forms an intake valve together with the Ansaugöffhung.
- the suction jet pump is driven by a drive current flowing over the drive line.
- the suction jet pump is arranged in a storage container and sucks fuel from a fuel tank into the storage tank. At low levels in the fuel tank, it may happen that some air is sucked in and passed into the storage tank, which leads to a foaming in the storage tank.
- the foam with its large volume displaces fuel, which can lead to a partial emptying of the storage container. This effect is also called dynamic leakage.
- a characteristic of the suction jet pump which represents the intake volume flow as a function of the driving current, runs comparatively steeply. Strong foaming occurs only from a critical negative pressure field in the intake of the suction jet pump, which is referred to below as the foam boundary.
- a suction jet pump is known, with a drive line, which upstream of the jet outlet has a pressure relief valve, which can flow fuel from a predetermined pressure in the treble line via a valve outlet directly into the storage tank.
- the suction jet pump according to the invention with the characterizing features of the main claim has the advantage that the foaming is avoided or at least reduced by the treble line has a opening into the suction bypass opening, which is arranged such that the bypass current acts on the valve member. In this way one becomes additional, directly dependent on the drive current flow resistance produced at the intake, so that the characteristic of the ejector runs flatter than in the prior art.
- the suction jet pump can thus be designed so that their suction or their intake flow in the desired drive current range is above the minimum power and below the foam limit.
- the bypass opening is arranged in the region above the valve member.
- the tether with an end portion extends into the suction chamber, wherein the bypass opening is provided in the end portion.
- valve member is provided in sections in the suction chamber, since in this way the liquid flowing through the bypass opening can best act on the valve member.
- valve member umbrella-shaped since such a valve is particularly inexpensive to manufacture, reliably seals and has a large effective area for the flow of the bypass opening.
- the drawing shows in section an inventive suction jet pump.
- the suction jet pump has a drive line 1, which opens via a jet outlet 2 into a suction chamber 3.
- the jet output 2 is designed, for example, narrows nozzle-shaped.
- a mixing channel 4 is arranged, which is arranged in an imaginary extension of the jet outlet 2, such that a from the jet outlet 2 of the drive line 1 emerging fluid jet via the suction chamber 3 passes straight into the mixing channel 4.
- the cross sections of the beam exit 2 and the mixing channel 4 therefore overlap in the projection.
- the mode of action of a suction jet pump is well known, so that it is described here only briefly: via the haulage line 1 and its jet outlet 2, a blowing current is introduced jet-shaped into the suction chamber 3.
- the motive flow is any liquid, but could in principle also be a gas.
- the propulsion jet of the Treb Arthur 1 ruptures surrounding fluid from the
- valve member 6 which cooperates with the suction port 5 and forms a check valve with this.
- the valve member 6 is designed umbrella-shaped according to the embodiment, but may also be arbitrarily different, for example T-shaped, double-T-shaped, conical, spherical, disc-shaped or cylindrical.
- the valve member 6 may be elastic or rigid.
- the treble line 1 has a bypass opening 10 opening into the suction chamber 3, which is arranged such that its bypass flow acts directly or indirectly on the valve member 6.
- the bypass flow acts on the valve member 6 in a closing manner, ie opposite to the opening direction of the check valve.
- the bypass opening 10 is directed onto the valve member 6 such that the jet or the flow of the bypass opening 10 strikes the valve member 6. At least it is provided that the volume flow of the bypass opening 10, the valve member 6 flows over and thereby exerts flow forces on this.
- the bypass opening 10 is designed and arranged such that its bypass flow exerts such a high force on the valve member 6 that the valve member 6 is movable in the direction of its valve seat.
- the bypass opening 10 may be designed such that the valve member 6 is completely closable by means of the bypass flow of the bypass opening 10.
- the diameter of the bypass opening 10 must be smaller than that of the line output 2 of the treble line. 1
- suction jet pump which represents the volume flow drawn in via the suction opening 5 as a function of the blowing current, is thereby flatter than in the prior art.
- the suction jet pump can thereby be designed so that their suction power in the desired drive current range is above the minimum power and below the critical foam limit. Due to the construction according to the invention, foam formation downstream of the mixing channel 4 is avoided or at least reduced by suction of air. It is achieved a self-regulating suction jet pump.
- the treble line 1 extends with a section 1.1 into the suction chamber 3, wherein the bypass opening 10 is located in the section 1.1. Upstream of section 1.1, for example, a section 1.2 which is angled relative to section 1.1 is designed, the bypass opening 10 being arranged, for example, in the region of the angling.
- the bypass opening 10 is formed, for example, on the underside of the section 1.1 facing the bottom 14.
- the Ansaugöffhung 5 is provided at the bottom 14 in the region below the bypass opening 10.
- the bypass opening 10 has an axis 10. 1 which is aligned with the intake opening 5 or the valve member 6 and can extend perpendicular or obliquely with respect to the floor 14.
- the axis 10.1 can be aligned with the axis of Ansaugöffhung 5.
- the suction opening 5 can also be arranged offset to the bypass opening 10.
- the suction jet pump is provided in a cup-shaped storage container 11 which is arranged in a storage container 12.
- the suction chamber 3 of the suction jet pump is designed, for example, open on one side and rests with the open side on a bottom 14 of the storage container 11, whereby the open side of the suction chamber 3 is closed.
- the Ansaugöffhung 5 of the suction chamber 3 is provided according to the embodiment of the bottom 14 of the storage container 11, but could also be embodied on the housing of the suction jet pump.
- the check valve formed from the Ansaugöffhung 5 and the valve member 6 prevents backflow of liquid from the storage tank 11 via the mixing channel 4 and the suction chamber 3 back into the reservoir 12th
- the mixing channel 4 extends horizontally in the direction of the bottom 14 of the storage container 11.
- the suction jet pump according to the invention according to Fig.l can be used for example in a device for conveying fuel.
- This has, for example, a delivery unit 16, which sucks fuel from the storage tank 11 and pressure increases via a pressure line 17 to a Internal combustion engine 18 promotes.
- the brake line 1 branches off, wherein a pressure control valve 19 may be provided, the line from a predetermined pressure fuel from the pressure line 17 into the drive 1 can flow.
- the storage tank 11 holds for the delivery unit 16 sufficient fuel, so that it can suck fuel even at low levels in the fuel tank 12 and when accelerating, braking, cornering and / or driving uphill.
- a partial emptying of the storage container 11 is avoided by sucking air and thereby causing foaming.
