Definitions
- the invention relates to a filter for use in a flowing, viscous medium, in particular in the flow of a hydraulic oil pump for an electrohydraulic valve control, according to the preamble of claim 1.
- the high-pressure hydraulic oil for controlling the hydraulic actuators actuating the gas exchange valves in the combustion cylinders of the internal combustion engine is made available by a high-pressure pump that works with hydraulic oil from a Hydraulic oil reservoir is supplied either directly by suction or indirectly via a pre-feed pump.
- a hydraulic oil filter is usually arranged on the inlet side of the high-pressure pump in order to separate dirt particles contained in the hydraulic oil.
- the filter according to the invention with the features of claim 1 has the advantage that the viscous flowing through the filter element of the filter by the electric heating device
- the filter housing has a pot shape and is divided by the filter element into a hollow cylindrical, outer filter chamber and into a cylindrical, inner filter chamber.
- a preferably ring-shaped electrode for applying a voltage potential of a heating voltage is arranged on each end face of the filter housing, from which electrically conductive current bars spaced apart from one another extend axially over the filter element.
- the heating device has a plurality of heating wires, which are arranged on the surface of the filter element and in each case between the Current bars of one electrode and the current bars of the other electrode are spanned.
- FIG. 1 is a perspective view of a filter for an electro-hydraulic valve control
- FIG. 2 shows a detail of a plan view in the direction of arrow II in FIG. 2 of a development of a heating device integrated in the filter
- FIG. 3 shows a section of the filter along the line III - III in FIG. 2.
- the filter shown in Fig. 1 is used in an electro-hydraulic valve control of gas exchange valves in internal combustion engines, as described for example in DE 198 26 047 AI.
- hydraulic oil is clamped to high pressure by a high-pressure pump.
- the hydraulic oil is from a hydraulic oil reservoir sucked.
- the high-pressure pump is often preceded by a pre-feed pump which conveys the hydraulic oil from the hydraulic oil reservoir to the high-pressure pump.
- the filter shown in FIG. 1 is arranged on the inlet side of the high-pressure pump, that is to say between the prefeed pump and the high-pressure pump.
- the filter has a cup-shaped filter housing 11 with an inlet 12 and an outlet 13, which are identified in FIG. 1 by flow arrows
- FIG. 3 shows sections of the jacket of the filter housing 11 is double-walled and the annular cavity between the two housing walls 111 and 112 is filled with a heat insulating material 14. Inside the filter housing 11 is a
- Filter element 15 arranged concentrically, which separates the inlet 12 from the outlet 13.
- the filter element 15 consists of a flat, band-shaped filter material, which lies folded in a star shape in a circular shape in the filter housing 11 and divides the filter housing 11 into a hollow cylindrical outer filter chamber 16 and a cylindrical inner filter chamber 17.
- the outer filter chamber 16 is connected to the inlet 12 on the filter housing 11 and the inner filter chamber 17 is connected to the outlet 13 on the filter housing 11.
- the filter element 15 is provided with an electric heating device 18, to which a heating voltage 19, here a direct voltage, is applied, which is taken off, for example, in a control unit 20 for the electro-hydraulic valve control.
- the electric heater 18 includes a plurality of heater wires 25, which are distributed over the filter element 15 and are arranged on the surface of the filter element 15, specifically on the side of the filter element 15 facing the outer filter chamber 16.
- the heating device 18 has an upper electrode 21, which is at the plus potential of the heating voltage 19, and a lower electrode 22, which is at the minus or ground potential of the heating voltage 19 lies.
- Current bars 23, 24 are arranged so that they are approximately the same distance apart as seen in the circumferential direction.
- the two electrodes 21, 22 are designed as electrically conductive ring surfaces which are arranged on the end faces of the filter housing 11.
- the current webs 23, 24 striving at right angles to this are designed in the exemplary embodiment shown as rods with a circular cross section, but can also have a flat cross section.
- the two electrodes 21, 22 are preferably manufactured with their current bars 23, 24 in one piece as a lead frame. Between each of the current bars 23, 24 of the upper and lower electrodes 21, 22, a heating wire 25 is stretched, which - as shown in FIG. 2 - runs in a zigzag shape between the two current bars 23, 24. The peaks or vertices of the heating wire 25 are electrically contacted on the one hand on the power web 23 and on the other hand on the power web 24. Alternatively, it is possible to give the heating wires 25 a meandering course between the current bars 23, 24, the apices of the meandering arches again being fixed in an electrically conductive manner on the current bars 23, 24.
- the hydraulic oil is very viscous, so it has a high viscosity.
- the electrical heating device 18 in the filter is switched on together with the high-pressure pump in a preliminary phase. The current flows from the top
- the discharged from the hydraulic oil reservoir cold hydraulic oil flow is heated by the heating wires 25 and filtered by the lying behind filter element 15 so that can be supplied by an appropriate heating time of the filtered and heated volume flow without pressure loss • by increased filter resistance of the high-pressure pump.
- the heat-insulating material 14 in the double-walled jacket of the filter housing 11 improves the heating power of the electric heating device 18.
- the filter described is not limited to use with an electro-hydraulic valve control. So it can be used wherever viscous media
- Liquids or gases that have a viscosity that depends on the operating temperature.
- An example of a further use is the use as a fuel filter for diesel injection systems.
