Definitions
- the invention relates to an electromagnetically actuated adjusting device for gas exchange valves of an internal combustion engine.
- Such actuators are known from DE-OS 35 13 105 or DE-OS 23 35 150.
- An armature plate oscillating back and forth between an opposing pair of magnets transfers its movement to a valve stem designed as a separate component, so that the one position of the armature plate is assigned an opening of the gas exchange valve and the other position is associated with a closure of the gas exchange valve.
- a spring system which acts on the anchor plate from the closed to the open position, and a second spring system which acts on the upper end of the valve stem from the open to the closed position.
- the dead center of this spring system is roughly assigned to the central position of the armature plate between the two opposite electromagnets.
- the spring system moves the armature plate away from the magnet when the magnet is switched off and allows the system to vibrate beyond the dead center in the vicinity of the opposite magnet.
- the anchor plate is captured and the system for actuating the gas exchange valve has changed from the open to the closed state or vice versa.
- the spring preload changes due to material fatigue and aging processes, so that constant conditions are not maintained over a longer operating state.
- the invention is based on the problem of improving a system known from the above-mentioned prior art in such a way that constant suspension properties of the spring systems are maintained over long operating periods.
- a three-spring system is used in the actuating device for the gas exchange valves, two springs of which act on the anchor plate on both sides.
- This spring system corresponds approximately to the system that is shown in a system known from DE-OS 30 24 109 in cooperation with an integral design of the anchor plate and valve stem.
- a third spring acts on the valve stem at its one end, opposite the valve plate, into the closed position of the valve plate.
- the only figure shows the principle of a fiction moderate adjusting device in sectional view.
- the magnetic cores 10 and 12 are designed as pot magnets and contain a coil 14 and 16, respectively.
- the two pole faces of these pot magnets 10 and 12 lie opposite one another, an armature plate 18 moves back and forth between them.
- an extension 34 of the anchor plate 18 In the bore 36 provided centrally in the pot magnet 10 there is an extension 34 of the anchor plate 18, which supports the guidance of the movement of the anchor plate 18.
- An outer sleeve 20 surrounds the system, it serves for shielding from the outside and also also for guiding the anchor plate 18.
- a cover 32 is provided, which also closes the bore 36 at the top.
- the cover 32 is also used as an abutment for a spring 38, which will be discussed further below.
- an extension 22 which lies in the central bore between the electromagnet 12 and contributes to guiding the armature plate 18.
- the underside of this extension 22 is designated 24, it is in contact with the valve stem end 26 of a valve stem 28.
- the valve stem 28 carries at its opposite end, not shown here, a valve plate, which is the inlet or outlet for the combustion chamber of an internal combustion engine in a known manner opens or closes.
- a first spring system shown here as spring 38, is provided between cover 32 and anchor plate 18 to apply the anchor plate 18 in the direction of the opening of the gas exchange valve.
- a second spring system shown here as a helical spring 40, is provided between the cylinder block 30 as an abutment and the lower end 24, which is connected to the anchor plate 18 via the extension 22.
- This coil spring 40 thus acts on the anchor plate 18 in a position which corresponds to the closed position of the gas exchange valve.
- a spring 42 is provided, which is arranged between the cylinder block 30 and the upper end 26 of the valve stem 28 and also acts on the valve stem 28 in the direction of the closed position of the gas exchange valve.
- the spring system 38 on one side of the armature plate 18 and the combined spring system 40 and 42 on the other side of the armature plate 18 act on the armature plate such that the equilibrium position of the armature plate between the two opposite pole faces of the magnets 10 and 12 is approximately in the middle.
- the spring 38 is designed stiffer than the spring 40, which is supported by the spring 42 in its action. However, it is assumed that there is still contact between the lower extension 24 and the upper shaft end 26 even in the closed position of the gas exchange valve.
- the coil 14 is switched off and the coil 16 is energized.
- the armature plate 18 is no longer held on the pole face of the pot magnet 10, the spring 38 presses the armature plate 18 in the direction of the central position between the pole faces of the magnets 10 and 12.
- the springs 40 and 42 are compressed.
- the springs 38 and 40 are designed differently rigid.
- the two springs can have the same spring constant, but then a further spring must be provided in the bore 36 between the cover 32 and the extension 34, the the spring 42 compensates so that the dead center of the armature plate 18 remains in the central position between the two pole faces and the system works at least essentially symmetrically on both sides. Inevitably, this additional spring can then only become effective over part of the path of the anchor plate 18.
- the three-spring system shown ensures constant spring conditions even over a longer period of time.
