Definitions
- the invention is based on a rotary actuator according to the preamble of claim 1.
- DE-OS 37 28 589 already discloses such a rotary actuator, the rotary slide of which, however, is rotatably mounted about an axis guided in two housing parts.
- the sealing between the pneumatic part and the electrical part takes place there through the throttle element covering the control opening in the pneumatic housing, which, however, must not "graze” despite the required tolerances. If dirt particles, chips or water droplets carried by insufficiently cleaned combustion air get through the sealing gap into the electrical part of the turntable, this can lead to malfunctions or corrosion. In addition, air can be sucked out of the electrical part in an undesired manner and falsify the desired fuel-air ratio.
- the servomotor according to the invention with the characterizing features of claim 1 has the advantage that the sealing of the electrical and pneumatic parts is further improved and the amount of leakage air is further reduced. This is achieved by the improved mounting of the rotary valve shaft, namely by its tolerance-reducing mounting in a single housing part without an intermediate plate, which leads to a noticeable reduction in the working air gap between the throttle element and the control opening. On the other hand, only the roller bearing between the pneumatic and the electrical part acts as a seal to protect the motor.
- the rotary actuator 1 has a servomotor 2, the rotor 9 of which acts on a throttle element 3 which is arranged in a bypass line 4 in a housing 12.
- the bypass line 4 is connected on both sides to an intake pipe 5 with a throttle valve for controlling the idle combustion air of an internal combustion engine.
- the throttle element 3 is seated in an opening 15 of the housing 12 which intersects the bypass line 4 and is designed as a rotary slide valve which more or less closes a control opening 6 on the supply air side of the bypass line 4.
- the arrow indicates the direction of flow in line 4.
- the servomotor 2 consists of a central stator 7 with field windings 8 and the cup-shaped rotor 9, which has two permanent magnet segments 10 arranged on its cylindrical jacket-shaped wall.
- the rotor 9 has a smooth, stepless shaft 11, which is mounted in two bearings 13, 14, which are held in the housing 12 and are arranged on both sides of the throttle element 3, and from which the cylindrical jacket-shaped wall of the rotor 9 extends.
- the throttle element 3, which projects into the opening 15 of the housing 12 and controls the bypass line 4, is fastened to the shaft 11.
- the bypass line 4 and the throttle element 3 together form the pneumatic part 16, while the stator 7 and rotor 9 form the electrical part 17 of the rotary actuator 1.
- the electrical part 17 is covered by a housing cap 18 in which the stator 7 is fastened on one side.
- the bearing 13 designed as a roller bearing is pressed between the pneumatic 16 and the electrical part 17 with its inner ring 20, possibly with the interposition of a ring 19, on the rotor shaft 11.
- the outer ring 21 of the bearing 13 is inserted into the housing 12 and is held by an angle disk 22.
- the angle disk is pressed against the bearing 13 by a shoulder 23 in the housing cap 18.
- Spring washer 24 inserted for pressing the bearing 13 against the housing 12 and for tolerance compensation. So that the rotor 9 is not pulled out of the housing 12 again due to the attraction of its permanent magnets 10 during the assembly of the stator 7, the angle disk 22 has lugs 25 directed towards the housing 12. These engage in an undercut groove 26 in the housing 12.
- the housing cap 18 is screwed to the housing 12 in a manner not shown.
- roller bearing 13 is filled with grease, also to increase the sealing effect.
- cover plates 27 are attached to the fixed outer ring 21 of the bearing 13.
- Bearing 13 and bearing 14 are arranged in the housing 12 on both sides of the opening 15.
- the rotary actuator 1 is installed by inserting the rotor shaft 11 with the rotary slide 3, bearings 13, 14 and rotor 9 and the inserted angle disk 22 into the housing 12 from above. Then the angle plate 22 is pressed against the housing 12 so that the lugs 25 engage. Finally, the housing cap 18 with the stator 7 fitted is put over the rotor 9, pressed against the housing 12 and screwed. The angle disk 22 presses against the bearing 13 and fixes it.
- the arrangement of the two bearings 13, 14 in the housing 12 allows a very precise machining of the holding openings for the bearings and the opening 15 for the rotary valve 3 in one setting, so that the rotary valve runs very precisely and the diameter tolerances of the rotary valve and opening are reduced can, resulting in only very small leakage gaps.
