Definitions
- the invention relates to a fuel filter, in particular a diesel filter, with at least one fuel inlet, at least one fuel outlet, means for separating water, at least one sump and a water drain assigned to the sump, and control means for the water drain.
- a fuel filter in particular a diesel filter, with at least one fuel inlet, at least one fuel outlet, means for separating water, at least one sump and a water drain assigned to the sump, and control means for the water drain.
- Fuel filters of this type are used, among other things, in diesel engines to filter out impurities contained in diesel fuel and to separate water from the diesel fuel in order to avoid malfunctions and damage such as impurities or corrosion in the fuel system or poorer combustion in the engine.
- a problem of such fuel filters is the removal of the water from the sump, since the water usually contains impurities after being separated from the fuel and is therefore not allowed to be released into the environment without further ado.
- a fuel filter of the type mentioned at the outset is known from US Pat. No. 4,264,442.
- the fuel filter has a chamber in which a cage is arranged.
- the cage defines one
- a fuel inlet chamber which is connected to the fuel inlet and a fuel outlet chamber which is opposite to the fuel inlet chamber and is separated therefrom by an intermediate wall and is connected to the fuel outlet. The one entering the fuel filter through the fuel inlet
- Fuel passes through the fuel inlet chamber, emerges from it via a porous wall into the chamber, circles the cage, and passes over the opposite side of the cage also porous wall into the fuel outlet chamber and from there flows out of the fuel filter as cleaned fuel via the fuel outlet.
- the bottom of the chamber outside the cage serves as a sump for water that was removed during filtration.
- a valve which is controlled with the aid of a water level sensor arranged in the sump and with which a water drain connected to a line can optionally be opened and closed.
- the valve is opened via a negative pressure generated at the water outlet, a substantial part of the water is sucked out of the sump and discharged via the line into a downstream chamber.
- a major disadvantage when draining water into such a chamber outside the fuel filter is that the chamber has to be emptied manually to collect the water and the fuel filter is therefore not maintenance-free.
- the _Was.ser is disposed of via the engine .directly, but there is the disadvantage that the connection of the water drain of the fuel filter to the engine is complex and therefore expensive. In addition, when the water is supplied to the engine's air intake system, there is the disadvantage that the combustion air during the drainage of the fuel filter is much wetter and the combustion is impaired at least for a short time.
- the object of the present invention is to provide a fuel filter which does not have the disadvantages mentioned above, in particular with regard to the removal of water, can be operated essentially independently of other engine parts and is maintenance-free.
- the fuel filter should also be simple in construction and therefore inexpensive to manufacture.
- This object is achieved in a fuel filter of the type mentioned by means of separating contaminants from the water to be drained.
- the water contained in the fuel can be separated, for example, by a corresponding coating on the clean side of the filter.
- an arrangement in which the sump is assigned to the dirt side of the filter can be as effective or even more effective.
- the water is separated off, for example, using a coating provided on the dirt side of the filter.
- the separated water collected in the sump is so clean that it can be drained directly into the environment.
- the means for separating contaminants from the water to be drained are made available directly via the filter.
- a filter for filtering the water to be drained from the sump can be provided as a means for separating contaminants from the water.
- This additional filter can be arranged, for example, directly on the water drain of the fuel filter, but also in or on a water chamber downstream of the sump, into which the water is drained from the sump.
- a suitable filter can be used to ensure that the water released into the environment is sufficiently clean.
- a water absorption and evaporation unit downstream of the water outlet and to the environment is provided as the separation means.
- the water to be drained can be separated from contaminants easily and without additional complex technical means by evaporation and can thus be released into the environment and disposed of without any problems.
- it must be ensured that not yet evaporated water is kept so stationary that it does not drain into areas where it must not enter for environmental, safety or other reasons.
- the water drain of the fuel filter is opened until a large part of the water collected in the sump or almost all of the water has drained off and is absorbed in the water absorption and evaporation unit, the water drain being closed again in time so that no fuel is drained from the swamp.
- intervals at which the fuel filter has to be drained are usually long enough so that until a subsequent drain of water from the sump, the previous amount of drained water can evaporate completely.
- the evaporation can be accelerated by the waste heat of the engine or can be deliberately accelerated if the water absorption and evaporation unit is positioned in the engine compartment.
- the evaporation can also be accelerated due to an air flow caused by airflow or via forced ventilation of the engine compartment.
- Another possibility for accelerating the evaporation consists in arranging an independent supply of heat in the water absorption and evaporation unit, for example an electrically operated heating coil, for which an electrical energy supply is then required, however.
- the water absorption and evaporation unit can, for example, be supplied with heat via the cooling system of the engine.
- the water absorption and evaporation unit has a container which is open to the surroundings in an upper region, preferably of a container temperature-resistant material such as polyamide.
- the inlet for the water drained from the fuel filter can take place, for example, via the opening in the upper region of the container, but for example also via a line on the side or, if appropriate, also at the bottom of the container.
- the opening at the top of the container can be provided with a fine-mesh cover, which prevents the water contained in the container from splashing out.
- the container thus serves as a kind of catch basin from which the water drained from the fuel filter does not flow out, but can nevertheless evaporate to the environment.
- the larger the cross section of the container in the area in which the water is held the larger the surface of the water available for evaporation.
- the water absorption and evaporation unit has an absorbent material, which in particular consists at least partially of an absorbent paper and / or is formed like a sponge, and which absorbs water that is removed from the sump of the fuel filter and holds it until it evaporates completely is.
- an absorbent material which in particular consists at least partially of an absorbent paper and / or is formed like a sponge, and which absorbs water that is removed from the sump of the fuel filter and holds it until it evaporates completely is.
- it can simply be arranged on the water drain of the fuel filter without a special container.
- the absorbent material In order to prevent the water from dripping from the absorbent material, it can also be arranged within a container which then serves as a drip protection device. In this embodiment, the absorbent material then simultaneously offers protection against water splashing out of the container.
- the water absorption and evaporation unit provides the largest possible evaporation surface for the water.
- the absorbent material preferably has a large surface. This .lass.t. yourself .
- a sponge-like material by means of a structure which is rib-like towards the surroundings, similar to cooling fins of a heat sink for electronic components.
- chemicals for binding the contaminants are provided as means for separating contaminants from the water to be discharged, which chemicals are either already stored in the sump and / or in a chamber downstream of the water drain.
- Fuel filter in the fuel line system different preferred locking systems.
- a controllable valve is preferably provided on the water drain. Due to the excess pressure in the fuel filter compared to the environment, the water is automatically pushed out of the sump when the valve is opened.
- a valve for closing the water drain can be actuated mechanically via a floating body, without the need for electrically operating water sensors or other electrical components to drain the water.
- the floating body located on the phase boundary between fuel and water lifts the valve so that water is drained off and, depending on the design, closes the valve again when a minimum water level is reached or undershot.
- a pump is preferably provided on the water drain.
- the pump is necessary to drain the water from the sump against the negative pressure prevailing in the fuel filter in relation to the environment.
- a volumetric pump is used as the pump, which has the advantage over other pumps shows that a clearly defined amount of water can be removed from the sump, so that it can be ensured that - starting from a maximum water level - just enough water is removed that no fuel is drained via the water drain.
- the use of a pump, in particular a volumetric pump is also advantageous if there is an overpressure in the fuel filter in relation to the environment.
- valve or the pump can be arranged in the sump
- Water level sensors can be controlled. In particular when using a volumetric pump, it is sufficient if only a water level sensor is used in the sump, which indicates when a certain water level has been reached or exceeded, since a precisely defined amount of water can then be removed from the sump via the volumetric pump. But even without a volumetric pump, a single water level sensor can be sufficient to control the valve or the pump, for example when the control specifies a defined time for which the valve is to be opened after the specific water level has been reached or the pump is to be actuated.
- two water level sensors are used, with which an upper and a lower filling quantity of the water in the sump can be determined, the opening and closing of the valve or the switching on and off of the pump can be completely controlled via the signals of the two sensors ,

- FIG. 1 schematically shows a fuel filter with a housing 1, on the upper side wall of which a fuel inlet 2 and a fuel outlet 3 are provided on opposite sides.
- a filter for filtering the fuel can be arranged in a fuel filter housing and which means are to be provided for separating water. Therefore, the arrangement of the filter in the fuel filter housing and the means for separating water from the fuel have been omitted for reasons of simplification.
- the lower region of the housing 1 serves as a sump 4 for water which is separated off when the fuel is filtered.
- a water drain 5 with a controllable closure is provided at the bottom of the sump 4, a water drain 5 with a controllable closure is provided.
- the closure is controlled by a control unit 6 as a function of the level signals of an upper water level sensor 7 and a lower water level sensor 8.
- a vertical line 9 is arranged on the underside of the closure.
- the line 9 ends in a container which is arranged below the housing 1 and is open to the top. Inside the container there is an absorbent material 12 for receiving water which is discharged from the sump 3 and which extends horizontally over the entire inner cavity of the container 11 extends.
- the absorbent material can, for example, at least partially consist of a sponge, an absorbent paper or a fleece.
- the closure can be designed as a valve if the pressure at the bottom of the sump is greater than the ambient pressure, so that the water can simply run off from the sump when the valve is open. This is always the case in particular when the fuel filter is arranged behind a fuel pump in the direction of flow of the fuel. If the pressure at the bottom of the sump is lower than the ambient pressure, a pump must be present on the closure 4, so that the water can be pumped out of the sump 4 against the pressure difference.
- valve is opened or the pump is actuated via the control unit 6 when the water level in the sump 4 of the fuel filter indicated by line 13 has reached the upper water level sensor 7. Conversely, the control unit 6 closes the valve or switches off the pump when the water level 13 has reached or fallen below the lower water level sensor 8.
- control unit 6 can determine the time for closing the valve or for switching off the pump on the basis of a time constant, which can be based, for example, on empirical data on the outflow rate of the water from the sump 4. Or a clearly defined amount of water is removed, as is possible, for example, when using a volumetric pump.
- the water is drained into the container 11, where it is absorbed by the absorbent material 12. If so much water is drained from the sump 4 that it cannot be completely absorbed by the absorbent material, the excess water can drip downward and be “collected on the bottom of the container ...
- the absorbent material 12 offers protection against Spraying out the water collected at the bottom of the container 11, so that pollution of the environment by dirt particles or oil residues dissolved in the water is reliably avoided. With appropriate dimensioning of the absorbent material, the water can evaporate completely into the environment in the period available for evaporation between the times in which water is drained from the sump of the fuel filter. Evaporation is usually supported by an increased ambient temperature due to the engine's waste heat.
- FIG. 2 shows a preferred circuit arrangement for controlling the water drainage with an upper and a lower one
- Water level sensor shown. It has a voltage source 21, four switches 22, 23, 24, 25, a relay 26 and a signal generator 27.
- the first switch 22 is switched by an upper water sensor, the second switch 23 by a lower water sensor.
- the third switch 24 and the fourth switch 25 are switched by the relay 26.
- the signal generator 27 is connected to the voltage source, the second and third switches 23, 24 are connected in series and are parallel to the first switch 22.
- the relay 26 is connected to the voltage source 21.
- the second switch 23 is switched on as long as the water level has not yet fallen below the lower water level sensor, ie has not dropped below a minimum water level.
- the first switch 22 is then switched on when the water level has reached the upper water level sensor, that is to say when a maximum water level has been reached or exceeded.
- the relay 26 is connected to the voltage source 21 and thereby switched.
- the third and fourth switches 24, 25 are short-circuited, so that the signal generator 27 is connected to the voltage source 21 and. on. Signal to open de.s._Wa_s.serabl.asses. for example, to open a valve or to operate a pump, and water can drain from the sump of the fuel filter.
- the first switch 22 is opened again. However, this has no influence on the switching state of the relay 26, since it is via the second and third switches 23, 24, both of which are still closed, remain connected to voltage source 21.
- the second switch 23 is only opened again when the water level has fallen below the lower water sensor and thus the minimum water level. As a result, the power supply to the relay 26 is interrupted, so that it switches over and the third and fourth switches 24, 25 are opened again. As a result, the signal generator 27 is disconnected from the voltage source 21, so that the signal level changes and the water drain is closed.
- FIG. 3 shows another preferred variant of a water sensor system for determining whether a maximum and a minimum water level has been reached.
- the water sensor system consists of a laser 31 which is arranged on one side of the sump 32 and is directed obliquely upwards.
- the laser 31 is preferably oriented so that its beam crosses a predetermined level as the minimum water level in the middle of the swamp.
- two light sensors 33, 34 are arranged one above the other, the first light sensor 33 being oriented such that the laser beam reflected at the phase edge between fuel and water strikes the sensor surface at a minimal water level, and the second light sensor 34 is oriented in this way is that the laser beam reflected at the phase edge strikes its sensor surface at maximum water level.
- Fuel filters such as water drainage etc. are not shown for the sake of simplicity.
- Such a water sensor system is particularly suitable for fuel systems in permanently installed, immovable combustion apparatus.
- FIG. 4 shows the principle of a float control for opening the water drain 41 at a maximum water level and closing the water drain .
- 41 at. a..minimal Wa_s_serp.egel represented.
- a float 42 which is designed so that it floats on the aqueous phase, but is heavier than the fuel, cooperates with a valve pin 43 so that it raises the valve pin 43 as soon as a certain maximum water level in the sump 44 is exceeded, and the valve pin 43 again lowers as soon as the water falls below a certain minimum level.
- the valve pin 43 is guided through a through opening 45 in the float 42.
- valve pin 43 It has at its upper end and in its lower area slightly above its valve cone 46 which closes the water drain 41 and acts as catches 47, 48 which cooperate with corresponding recesses 49, 50 on the top and bottom of the float 42. If the float 42 exceeds the maximum water level, the valve pin 43 is raised so that the water drain 41 is opened. The valve pin 43 then remains in its raised position until so much water has been drained from the sump that the floating body, which descends with the water level, presses the valve pin 43 downward, so that the water drain 41 is closed again when the minimum water level is reached , A guide mechanism for the valve pin 43 is not shown for reasons of simplification.
- FIG. 5 shows the sump 51 of a fuel filter with a water drain 52, which can be opened and closed via an electromagnetically closable valve 53 and to which a filter body 54 connects, by means of which the water drained from the sump 51 is cleaned, so that it can be drained immediately to the environment.
- the filter body 54 can also be designed as a sponge, which
- Water drain should be opened. Or a floating body can be used which does not interact directly with a valve pin but with a valve pin via a lever mechanism. Filters for cleaning the drained or drained water can also be optionally linked to one another with a system for evaporating the purified water or a system for binding contaminants by chemicals or catalysts.
