Definitions

  • the invention relates to a device for actuating a gas exchange valve designed as a poppet valve of a reciprocating piston internal combustion engine according to the preamble of claim 1.
  • Such a valve actuation device is known from EP-PS 0 118 591.
  • Two electromagnets which are excited out of phase with each other, form an oscillation system with two coil springs, which rest on both sides of an armature disk attracted by the electromagnets.
  • the poppet valve connected to the armature disk is moved back and forth and thereby opens or closes a fluid passage opening. If such a device is used to actuate a gas exchange poppet valve of a reciprocating piston internal combustion engine, it is important to keep the mass of the spring system as small as possible in order to obtain precise control over the entire speed range of the internal combustion engine on the one hand and the energy requirement for the electromagnets on the other hand to be kept to a minimum size.
  • the characterizing features of claim 1 serve to solve this problem.
  • the torsion bar spring used for valve actuation does not have any oscillating masses which negatively influence the oscillating system. Even the rocker arm rigidly connected to the torsion bar spring, which is in operative connection with the poppet valve, has only a very small reduced mass, so that the armature articulated on the valve lever follows the alternating excitations of the electromagnets almost without inertia and can control the poppet valve accordingly.
  • a similar torsion bar spring is known from DE-AS 1 120 804 for a purely mechanical valve control actuated by a cam.
  • the use of a torsion bar spring for an electromagnetic valve control has the decisive advantage that it becomes functional in the first place by eliminating the translationally moved spring masses and correspondingly reducing the inertial forces and can be operated with a still reasonable amount of energy for the power supply of the electromagnets.
  • the torsion bar spring is rotatably connected at one end to the valve lever and is mounted in two bearing blocks arranged on both sides of the valve lever; at the other end, the torsion bar is clamped in a rotationally fixed manner in a holding bush screwed to the cylinder head.
  • the armature which is mounted so as to be longitudinally movable in the center of the two electromagnets, is articulated on the valve lever in such a way that its distance from the longitudinal axis of the poppet valve is considerably smaller than its distance from the longitudinal axis of the torsion bar or the bearing center of the valve lever. In this way, an adapted travel ratio can be achieved, from the valve stroke of the poppet valve, which is optimized according to the dynamic considerations, to the stroke movement of the armature which is useful for commercially available electromagnets.
  • the fork-shaped end of the valve lever engages between a thrust washer resting on a shoulder of the valve stem and a sliding sleeve which is guided longitudinally on the valve stem and is supported by a coil spring against a holding sleeve attached to the end of the valve stem.
  • a hydraulic damping device is fitted in the cylinder head above the valve stem.
  • damping discs lie in an oil-filled cylindrical damping room.
  • a magnet housing 2 is fixed to the cylinder head 1 of a reciprocating piston internal combustion engine, in which a first electromagnet 3 and a second electromagnet 4 are fixedly attached at a distance a1 from one another.
  • armature disk attached to an armature 5, which is drawn towards the respectively excited electromagnet 3 or 4.
  • the armature is mounted at its free end in a bearing 8 of the magnet housing 2.
  • the other end of the armature 5 is screwed into a rod head 8 which is articulated with a pin 9 to a fork 10 of a one-armed valve lever 11; the rod head 8 which has just been milled is located with lateral play between the fork 10.
  • the front end of the fork 10 engages between a thrust washer 13 resting on a shoulder of the valve stem 12 and one on the valve stem. 12 a longitudinally movable sliding sleeve 14, which is supported by a helical spring 15 against a holding sleeve 16 fastened to the valve stem 12.
  • a small distance b is provided between the sliding sleeve 14 and the holding sleeve 16 in order to enable a resilient tolerance compensation between the armature stroke a2 and the valve stroke s of the poppet valve 17.
  • a damping sleeve 18 is fastened which, when the poppet valve 17 is closed, penetrates into the oil-filled damping cylinder 19 formed in the cylinder head, in which a plurality of damping disks 20 lie. In doing so, it displaces the oil into the oil inlet bore 21 and into the throttle gap 22.
  • This damping device reduces the noise of the valve train and reduces wear on the valve disk 23 and seat ring 24. The amount of damping can be adjusted by the oil inlet pressure and the dimensioning of the throttle gap.
  • the end is designed as a bearing tube 25 with two radially projecting collars.
  • the bearing tube 25 is mounted on both sides in a bearing block 27 or 28 screwed to the cylinder head 1; the collars 26 lying on the end faces of the bearing blocks 27, 28 secure the bearing tube 26 against axial displacement.
  • one end of a cylindrical torsion bar spring 29 is fastened in the bearing tube 25 with a serration connection 30.
  • the other end of the torsion bar spring 29 is also non-rotatably connected with a serration connection 30 in a holding bush 31 which is provided with elongated holes 32 and is flanged to the cylinder head 1.
  • the distance c1 of the articulation point of the armature 5 on the valve lever to the longitudinal axis of the poppet valve 17 is smaller than the distance c2 to the center of the bearing of the valve lever 17 in order to be able to translate the armature stroke a2 to the valve stroke s.
  • the electromagnet 3 is energized.
  • the electromagnet 3 is de-energized and at the same time the electromagnet 4 is energized, but because of the large distance a2 it cannot exert any noticeable force on the armature disk.
  • the initial movement to open the poppet valve is effected by the tensioned torsion bar 29, which is only relaxed on half of the armature stroke. From here, the armature disk 6 is applied to the electromagnet 4 by the strongly progressively increasing magnetic force of the electromagnet 4 and the inertia force of the valve mechanism, the poppet valve 17 going into the open position and the torsion bar spring 29 being tensioned again, this time in the other direction of rotation.
