Definitions
- the invention relates to a control valve for a device for the variable adjustment of the timing of gas exchange valves in internal combustion engines according to the preamble of claim 1.
- the object of the invention is to provide a cost-effective to manufacture and to be mounted control valve with improved reliability.
- the pressure medium guide insert has a guide sleeve in which the control piston is guided, the guide sleeve a Plastic encapsulation, in which at least two of the Druckstoffleitkanäle are arranged, and between the plastic extrusion and the guide sleeve, a filter fabric is provided.
- the pressure medium insert with the guide sleeve and the encapsulation has a two-part construction and a filter fabric is provided between the two parts.
- the filter required for the pressure medium is thus already integrated into the pressure fluid feed, so that the chip risk and the manufacturing and assembly costs are eliminated by the previously required separate part.
- the invention offers the advantage that the filter is arranged as close as possible to the control edges of the Druckstoffleitunes, so that they are best protected against dirt particles.
- the filter element are associated with at least two Druckmitmitelleitkanälen, wherein it is further proposed that the filter fabric is associated with at least one inflow and outflow channel.
- the pressure medium can be filtered with very little effort in the Druckmitmitititkanälen with only a single filter fabric. This creates a considerably larger filter area compared to the state of the art, whereby a better cleaning of the pressure medium is created.
- the filter fabric may be partially surrounded on both sides by the encapsulation, whereby the connection between the two parts is reinforced.
- the filter fabric may also be formed tubular so that it is automatically assigned to all peripheral openings of the Druckmitmitititkanäle after mounting on the guide sleeve and after encapsulation. This creates the largest possible filter surface and protects all control edges with just one filter fabric.
- the structure of the control valve can be further simplified by the injection at its end facing the camshaft having a guide for a check valve. This eliminates the previously required use in the control valve and the number of parts of the control valve is further reduced.
- the guide sleeve can be designed as Stahlteii, and serves on the one hand as a guide element for the control piston arranged therein and on the other hand as a dimensionally stable part in the overmolded two-part Druckstoffleitinate.
- the filter fabric may be formed elastically expandable, so that it can be wound on the guide sleeve with expansion. Furthermore, the filter fabric can thereby yield possible loads from the changing pressure fluid flows, without the risk of sudden unforeseen tearing exists.
- the filter fabric may be formed from a low-cost plastic, so that it can merge with the plastic extrusion.
- a steel mesh made of stainless steel can be used, which is advantageous in terms of the temperature of the pressure medium and occurring permanent loads.
- the tissue has diamond-shaped openings.
- an expandability of the tissue is independent of its matrialigenticianen given.
- Fig.1 Device for variable adjustment of the timing of gas exchange valves of an internal combustion engine with control valve according to the invention
- Fig.2 Control valve with pressure medium insert with integrated filter
- Fig.3 Pressure medium insert with integrated fabric
- a device for variable adjustment of the timing of gas exchange valves of an internal combustion engine which has a drive wheel 6 that is rotatably connected to a stator 7. Further, a rotor 8 is provided which is rotatably connected to a camshaft 4.
- the drive wheel 6 is driven directly or indirectly by the crankshaft of the internal combustion engine.
- the rotational movement of the drive wheel 6 is then transmitted via the stator 7 to the rotor 8, so that the camshaft 4 connected non-rotatably connected to the rotor 8 is also rotated.
- the rotating camshaft 4 then controls the opening and closing times of the gas exchange valves of the internal combustion engine.
- the adjustment of the timing of the gas exchange valves is then carried out by relative rotation of the rotor 8 relative to the stator 7, which is controlled by the control valve 1.
- the control valve 1 comprises a camshaft-side pressure medium inlet “P” and arranged at the end facing away from the camshaft 4 th pressure medium outlet "T". Further, two working ports “A” and “B” are provided, which communicate with the pressure chambers between the rotor 8 and the stator 7.
- a Druckstoffleitdon 10 is arranged, the Druckstoffleitkanäle 11, 12,13,14, the fluidically connected to the inlet port "P", the drain port "T” and the Häan- conclusions "A” and “B” or connectable are.
- a control piston 3 is guided displaceably.
- the pressure medium guide insert 10 has a two-part construction with a guide sleeve 15 and an encapsulation 16.
- the guide sleeve 15 is provided with openings 14 which can be closed by a control piston 3 guided on the inside of the guide sleeve 15.
- the encapsulation 16 is provided on the outside with the Druckstoffleitkanälen 11, 12 and 13. All pressure medium guide channels 11, 12, 13 and the openings 14 are provided with a filter cloth 17, which is integrated in the pressure medium guide insert 10.
- the filter fabric 17 is arranged on the guide sleeve 15 before the extrusion coating, so that this is itself part of the pressure medium insert 10 after the extrusion coating.
- the filter fabric 17 is tubular and thus covers after slipping over the guide sleeve 15 and the encapsulation automatically all circumferentially on arranged in the Druckstoffleitrus 10 Druckstoffleitkanäle 11, 12,13 and the openings 14, this being independent of the number, the geometry and the arrangement of the same is.
- the filter fabric 17 is on both sides of the camshaft 4 facing end 19 of encapsulation, so that here a particularly strong physical connection between extrusion 16 and filter fabric 17 is created.
- a guide 18 for the closure body 21 of a check valve 5 in the inlet channel "P" is provided on the pressure medium guide insert 10 on its side facing the camshaft 4.
- the guide 18 is formed by an externally accessible opening into which the closure body 21 can be inserted
- a sealing part 20 is connected to the encapsulation 16 from the outside, and the closure body 21 is spring-loaded against the sealing part 20 when the nonreturn valve 5 is closed 10 2005 052 481 A1, the number of individual parts of the control valve 1 being further reduced, with the additional advantage that the check valve 5 can be pre-assembled and assembled with the pressure medium insert 10 as a subassembly the spring passage end having, so that s of the Closure body 21 after insertion into the guide 18 and the fastening of the sealing member 20 captive in the guide 18 is added.
