Definitions
- Pressure pulsation damper for a fuel injection system and fuel injection system
- the invention relates to a pressure pulsation damper for a fuel injection system, in particular a common rail injection system, with the features of the preamble of claim 1. Furthermore, the invention relates to a fuel injection system, in particular a common rail injection system, with such a pressure pulsation damper.
- strong pressure pulsations can occur, which can be associated with high pressure spikes. These are primarily due to the lifting movement of a pump piston of a high-pressure pump of the fuel injection system, in particular when during the delivery stroke of the pump piston one of the filling of the high pressure pump with fuel serving suction valve remains open at least temporarily to push an excess amount of fuel back into the inlet area.
- Pressure pulsations can mechanically load a fuel injection system or components or lines arranged therein to such an extent that they are damaged. Furthermore, they can affect the functionality of individual components. For example, a pressure and / or quantity wave can cause a fuel filter arranged in the fuel system to be backwashed. As a result, the filter effect of the fuel filter can be impaired.
- Fuel injection systems are known from the prior art, which use an overflow valve for damping pressure pulsations.
- the Abgresmenge is doing fed to a return.
- the pressure upstream of the spill valve reduces, which may affect the filling of the high pressure pump. Inadequate filling, however, decreases the efficiency of the high-pressure pump.
- German Offenlegungsschrift DE 10 2006 037 179 A1 discloses a fuel injection system which comprises a high-pressure source and at least one fuel injector connected to the high-pressure source via a fuel pressure line.
- a pressure vibration damper is arranged in the fuel pressure line. This has a tubular conduit section with at least one radially extending throttle bore, via which fuel can be discharged into a pressure damping chamber.
- the present invention has the object to provide a pressure pulsation damper for a fuel injection system, which is simple and inexpensive to produce and also easy to integrate into a fuel injection system.
- the integration should in particular in the low pressure region of the fuel injection system, preferably in the inlet region of a high-pressure pump, take place to dampen pressure pulsations occurring there, so that the filling of the high-pressure pump is improved.
- a fuel injection system is also to be provided, which has an increased robustness due to a reduced mechanical load.
- the pressure pulsation damper is proposed with the features of claim 1. Advantageous developments of the invention can be found in the dependent claims. In addition, a fuel injection system is specified with such a pressure pulsation damper.
- the pressure pulsation damper proposed for a fuel injection system comprises a tubular line section in which a fuel channel is formed which has at least one jacket-side opening in the tubular line section with a pressure damping chamber. is bound.
- the pressure damping chamber is at least partially filled with gas and / or contains at least one gas-filled element.
- the tubular passage portion forming a fuel passage facilitates integration of the pressure pulsation damper into a fuel injection system.
- both ends of the pipe-shaped pipe portion may be connected to a fuel pipe so that the pipe-shaped pipe portion forms or replaces a part of the fuel pipe.
- pressure pulsations occur in the fuel line, they spread into the fuel channel and from there to the pressure damping chamber of the pressure pulsation damper. There, the pressure peaks associated with the pressure pulsations cause a compression of the existing gas volume in the pressure damping chamber, so that the pressure peaks are damped or compensated. A further spread of the pressure pulsations is therefore suppressed.
- the gas present in the pressure damping chamber absorbs energy. If the pressure in the system subsequently drops again, for example in the suction phase of a high-pressure pump of the fuel injection system, the energy absorbed by the gas is returned to the fuel. This process helps to fill the high-pressure pump so that the efficiency of the high-pressure pump is increased.
- the gas volume present in the pressure damper space of the proposed pressure pulsation damper can be designed to be continuous or distributed over many self-contained gas volumes.
- the many self-contained gas volumes can also all be the same or different.
- the pressure damping chamber of the pressure pulsation damper is filled with gas, wherein the gas-filled part of the pressure damping chamber is separated from the fuel channel of the tubular conduit section by a membrane.
- the material of the membrane is fuel resistant to effect a permanent tight separation.
- the material of the membrane should be elastically deformable to allow compression of the gas volume.
- the gas-filled part of the pressure damping chamber is separated by a float from the fuel passage of the tubular conduit section.
- the float rises and falls with the liquid level in a fuel-filled portion of the pressure-damping space, with the volume of gas preferably "above” experiencing a reduction or increase in pressure and / or volume
- the pressure pulsation damper need only be integrated into a fuel injection system in such a way that the gas-filled part of the pressure damping chamber comes to rest above the part filled with fuel.
- the pressure damping chamber is preferably cylindrical.
- a cylindrical pressure damping chamber can be filled in a simple manner with gas or with at least one gas-filled element.
- a cylindrical pressure damping chamber is particularly well suited for receiving a float, whose task is to separate the gas volume of a fuel volume.
- the float is preferably piston-shaped in this case. A remaining between the piston-shaped float and the cylindrical pressure damping chamber circumferential radial gap ensures the mobility of the float.
- the pressure damping chamber contains at least one gas-filled element.
- the element is preferably formed as a hollow body, wherein the size and / or the shape of the element is freely selectable. In this way, the size and the shape can be adapted to the size and shape of the pressure damping chamber.
- the gas-filled element may be spherical.
- the pressure damping chamber contains a plurality of gas-filled elements, which are preferably all of a similar design. For example, a plurality of spherical gas-filled elements can be accommodated in the pressure damping chamber.
- the at least one gas-filled element is at least partially formed from an elastically deformable material.
- the elastic deformability allows a reduction of the enclosed gas volume.
- the pressure damping chamber contains a plurality of gas-filled elements, which are accommodated relative to each other movable in the pressure damping chamber.
- a pulsation damping can already be effected via the movement of the elements relative to each other or through the formation of different sized spaces between the gas-filled elements in which the pressure waves extend or cancel each other.
- the pressure damping chamber is annular and surrounds the tubular conduit section.
- the annular design has the advantage that the connection of the pressure damping chamber with the fuel channel in the interior of the tubular conduit section over several, preferably at the same angular distance arranged mutually mantelsei- term openings can be prepared.
- the annular design of the pressure damping chamber requires a small space requirement, this is especially true when multiple annular Druckpulsationsdämpfer be switched one behind the other, to provide a sufficiently large volume of gas for Druckpulsationsdämpfung.
- the tubular conduit section forms or comprises at least one end of a connection piece, via which the pressure pulsation damper can be connected to a fuel line and / or to a housing part of a component of the fuel injection system.
- the component may in particular be a fuel pump, preferably a Radial piston pump, act, which preferably has a corresponding recess in a housing part for receiving the connecting piece.
- the provided on at least one end of the tubular conduit section connecting piece simplifies the integration of the Druckpulsationsdämpfers in a fuel injection system.
- the further proposed fuel injection system in particular common rail injection system, is characterized in that it comprises a pressure pulsation damper according to the invention.
- the pressure pulsation damper is arranged in a low-pressure region of the system, in particular in the inlet region of a fuel pump.
- the advantages of a Druckpulsationsdämpfers invention particularly well come into play, since in the low pressure region, especially in the inlet region of a fuel pump particularly frequently pressure pulsations occur that can burden the system and affect the function of individual system components.
- the pressure pulsation damper according to the invention is arranged in the inlet region of a fuel pump, it is at the same time possible to ensure sufficient filling of the pump with fuel via the pressure pulsation damper. This is especially true when the fuel pump is a radial piston pump.
- the fuel pump of the proposed fuel injection system is preferably a radial piston pump.
- total gas volume is much greater than the displacement volume of the stroke movable pump piston of the radial piston pump selected.
- the total gas volume is many times greater than the displacement volume of the pump piston.
- 1 shows a schematic longitudinal section through a first preferred embodiment of a Druckpulsationsdämpfers invention
- 2 shows a schematic longitudinal section through a second preferred embodiment of a pressure pulsation damper according to the invention
- Fig. 3 is a schematic longitudinal section through a third preferred embodiment of a Druckpulsationsdämpfers invention.
- FIG. 4 shows a schematic cross section through the pressure pulsation damper of FIG. 3.
- the pressure pulsation damper 1 shown in FIG. 1 comprises a tubular conduit section 2 to which a cylindrical pressure damping chamber 5 is attached in a peripheral region.
- the pressure damping chamber 5 is connected via a tubular extension 14 and a shell-side opening 4 formed in the tubular conduit section 2 to a fuel channel 3 of the tubular conduit section 2, so that fuel passes from the fuel channel 3 into the pressure damping chamber 5.
- the pressure damping chamber 5 is only partially filled with fuel 12, since another part of the pressure damping chamber 5 is filled with a gas 6.
- the gas 6 is air, which forms a compressible gas volume in the pressure damping chamber 5.
- a certain separation between the fuel 12 and the gas 6 is effected via a piston-shaped float 8, which floats on the fuel and rises at a pressure and / or quantity wave flowing through the fuel channel 3 with the fuel level in the pressure damping chamber 5 and thereby the gas volume above reduced. In this way, an attenuation of the pressure and / or mass waves is effected.
- the floating seat of the float 8 in the pressure damping chamber 5 is ensured by a radial gap 13.
- FIG. 1 Another preferred embodiment of a pressure pulsation damper according to the invention is shown in FIG. This differs from that of FIG. 1 in particular in that the gas volume is distributed over many elements formed as hollow spheres 7, which are filled with the gas 6. On the outside, the elements 7 are surrounded by the fuel 12. The gas-filled elements 7 are formed of a material which is elastically deformable. Under pressure, the elements deform 7, wherein the gas 6 is compressed. At the same time, the elements 7 move relative to each other, creating new gusset spaces in which pressure and / or bulk waves can pass.
- the pressure pulsation damper 1 thus has different modes of action that are used simultaneously and thus make the pulsation damping even more effective.
- the pressure pulsation damper 1 of FIG. 2 also has a tubular conduit section 2, which forms at its two ends in each case a connecting piece 9, 10, via which the pressure pulsation damper 1 to a fuel line (not shown) or to a housing part 11 of a fuel pump (not shown) can be connected.
- a connecting piece 9 in the housing part 11 a corresponding recess 15 is provided for this purpose, in which the connecting piece 10 can be inserted or pressed.
- the press fit also ensures a fluid-tight connection.
- the pressure pulsation damper 1 shown there can also have a connecting piece 9, 10 at at least one end.
- the pressure damping chamber 5 is annular and arranged around the tubular conduit section 2.
- a plurality of shell-side openings 4 connect the fuel channel 3 formed in the interior of the tubular conduit section 2 to the annular pressure-damping chamber 5 in which a plurality of spherical gas-filled elements 7 are received in an annular arrangement (see FIG. 4).
- the elements 7 are surrounded on the outside by fuel 12 so that pressure and / or mass waves occurring in the fuel 12 are damped by elastic deformation of the elements 7.
