Definitions

  • the invention relates to an actuator for the reversible movement of a valve flap of a valve and to a use of the actuator.
  • Actuators for the reversible movement of valve flaps are known.
  • the valve flap is attached to a drive shaft, which is connected to an electric motor via a constant transmission ratio.
  • it is disadvantageous that the valve flaps are relatively difficult to set in motion after longer operating times due to contamination in the valve. Due to the contamination, the valve flaps stick or bake in the valve and can only be released from the jammed state with a relatively large torque, which is often not possible or only with a delay due to the constant transmission ratio.
  • the invention is therefore based on the object of providing an actuator for the reversible movement of a valve flap of a valve, which allows the valve flap to be released relatively easily, even when heavily contaminated
  • the invention has for its object to provide a use of the valve.
  • the object underlying the invention is achieved by an actuator for the reversible movement of a valve flap of a valve, which consists of a drive shaft to which the valve flap is fastened, in which a toothed segment is rotatably mounted about the first axis of rotation Dl of the drive shaft, the toothed segment not tight with the drive shaft
  • a further segment which is larger than the toothed segment, is arranged and is firmly connected to the drive shaft, in which between the toothed segment and the further segment, a two-sided lever about a second axis of rotation D2 of a bolt, which is parallel to the first axis of rotation Dl is arranged on the side of the further segment facing the toothed segment, is rotatably mounted and does not touch the drive shaft, the first axis of rotation Dl being at a greater distance from the ring gear of the toothed segment than the second axis of rotation D2 and that of the first axis of rotation Dl in the closed position of the valve facing first lever arm a of the two-sided lever is greater than the distance c between the second axis of rotation D2 and that edge of the further segment which, in the closed position of the valve, lies flush with an edge of the toothed segment against a first stop, where the tooth segment is a recess ung and at the end of the tooth segment
  • the valve flap is usually attached to the end of the drive shaft.
  • the actuator is driven by an electric motor that rotates the toothed segment.
  • the further segment is designed in the form of a partial circle, its partial circle being larger than the partial circle of the toothed segment.
  • the further segment can, for example, also be designed as a tooth segment.
  • the two-sided lever is advantageously made of flat material. It is rotatable on the bolt, which is arranged parallel to the first axis of rotation D1 on the side of the second segment facing the tooth segment,
  • the two-sided lever does not touch the drive shaft. This applies to all positions during the operation of the actuator.
  • the open position of the valve is defined by the fact that both the toothed segment and the further segment abut the second stop, with direct contact being able to take place via the third stop, which is fixedly arranged on the further segment.
  • the third stop is arranged, for example, on the further segment on its side facing the tooth segment.
  • a preferred embodiment of the invention consists in that the side of the two-sided lever facing the first axis of rotation D1 is formed by two partial arms arranged at right angles to one another. It is advantageous
  • an eccentric arrangement of the bolt with respect to the two-sided lever can be dispensed with.
  • the toothed ring of the toothed segment engages directly in the pinion of an electric motor. It is advantageous that the arrangement of further transmission elements, such as intermediate wheels, can be dispensed with.
  • the further segment is connected to a spring element, the spring force of which is aligned with the further segment in the direction of the first stop.
  • the spring element can be, for example
  • Act leg spring The further segment can be connected directly or indirectly to the spring element via a connecting part. It is advantageous that even if the electric motor fails, the force of the spring element can be used to actuate the actuator such that the
  • Valve flap is brought back into the closed position of the valve.
  • the invention relates to the use of the actuator for the reversible movement of a valve flap of a gas recirculation valve of a motor vehicle.
  • the actuator for the reversible movement of a valve flap of a gas recirculation valve of a motor vehicle.
  • the valve flap of a gas recirculation valve can be moved easily even with relatively heavy contamination by the actuator.

  • Fig. 2 shows the top view of the actuator in a position between the closed and the open position of the valve.

  • Fig. 1 the actuator is shown in the form of a top view in the closed position of the valve.
  • the actuator consists of a drive shaft 1 to which the valve flap (not shown) is attached.
  • a toothed segment 2 is rotatably supported about the first axis of rotation Dl of the drive shaft 1, the toothed segment 2 not being firmly connected to the drive shaft 1.
  • a further segment 3, which is larger than tooth segment 2, is arranged parallel to tooth segment 2. In contrast to the toothed segment 2, this further segment 3 is firmly connected to the drive shaft 1.
  • This two-sided lever 4 does not touch the drive shaft 1.
  • the first axis of rotation Dl is at a greater distance from the ring gear of the toothed segment 2 than the second axis of rotation D2.
  • the tooth segment 2 has a cutout 2a.
  • a projection 4a is arranged on the two-sided lever 4, which is guided in a recess 2a which has the toothed segment 2.
  • the further segment 3 has a third stop 7 for the second tooth segment at its edge facing a second stop 6, which is to be assigned to the open position of the valve.
  • the first lever arm a of the two-sided lever 4 facing the first axis of rotation 1 D1 is larger than the distance c shown in FIG. 1 between the second axis of rotation D2 and that edge of the further segment 3 which, in the closed position of the valve, is flush with one edge the tooth segment 2
  • a projection 4a is arranged on the two-sided lever 4, which is guided in the recess 2a. While the toothed segment 2 is moving clockwise, the two-sided lever presses against the first stop 5 due to its first lever arm a. As a result, the further segment 3 is also moved in the direction of the second stop 6 in a clockwise direction. If the rotational movement of the toothed segment 2 is continued, the toothed segment 2 reaches the third stop 7.
  • both the toothed segment 2 and the further segment 3 in the direction of the second stop 6 each become moves at the same speed.

  • Both the toothed segment 2 and the further segment have now reached the second stop 6, which is to be assigned to the open position of the valve.
  • the tooth segment 2 and the further segment 3 can rest directly or indirectly on the second stop 6. If the valve is to be closed again, this movement is reversible until the state shown in FIG. 1 is reached again.

  • the further segment 3 is connected to a spring element 3b, the spring force of which is aligned with the further segment 3 in the direction of the first stop (not shown).
  • the connection between the further segment 3 and the spring element 3b takes place indirectly via a
  • the actuator shown is particularly advantageously suitable for the reversible movement of a valve flap of a gas recirculation valve of a motor vehicle.
  • FIG. 6 shows an actuator according to the prior art.
  • a valve flap 8 ' is firmly connected to a drive shaft 1'.
  • a toothed segment 2 ' is arranged on the drive shaft I 1 and is connected to the pinion 9' of an electric motor 11 'via an intermediate wheel 10'.
