For this reason, the valuation device is provided preferably, said valuation device is connected with at least one position switch and counting device.
For example from the position that limits or when arriving different angular positions zero point, only providing, a position switch is fine.This is fine when 360 spend especially, and arrive a certain angle from the position of qualification or at the zero point that limits by means of the counting device according to the utility model this moment.By means of estimation unit, further passable at this is through littler angle of the rotation reply of control motor or shorter distance.This is favourable especially in revolving valve.For example, revolving valve can use in having the exhaust gas recirculation zone of cooling off the bypass adjusting simultaneously.At this, can control different delivery temperatures or air displacement simultaneously.
The controlling device that is used for valve using according to the utility model preferably is provided with two position switchs, in particular for the position switch of test end location (for example opening of valves, valve are closed).Counting device by according to the utility model can be through the some neutral positions between two end positions.
Preferably, each position switch has the sensor of a fixed-site common, that be used for magnetic field detection.
Preferably, sensor is suitable for discerning sense of rotation.
Preferably, provide one pole Hall transducer or the bipolar Hall transducer that latchs as sensor.
Advantageously provide the magnet that is connected with live axle as counting device especially, said magnet is cooperated with the sensor of the fixed-site that is used for magnetic field detection.Sensor is Hall transducer or Hall switch preferably.The variation in the sensor magnetic field through fixed-site, said changes of magnetic field is corresponding to the revolution of live axle when simple magnet is provided.Especially the conversion of electric motor that has high revolution and corresponding transmission device than the time, can realize the sufficient precision of position, angle to be determined through simple magnet is provided.For further improving this precision or, multi-pole magnet can being provided for using the electric motor that has higher revolution.Each changes of magnetic field through sensor is therefore corresponding to the non-complete rotation of live axle, but turns over the rotation of several angle corresponding to live axle.For example, in the situation of the magnet that is connected with live axle of 18 utmost points, so changes of magnetic field turns over 20 degree corresponding to live axle.According to the structure of transmission device, the angle of valve changes only corresponding to the several years.Therefore, can strictly confirm the position of valve with simple mode.
Preferably, be used for the detection position and be used to detect two position switchs of two final positions especially preferably each has a magnet, especially tack magnet, wherein magnet is to have the mode of certain distance to be connected with said live axle with live axle.Preferably, magnet connects with the gear that is connected with live axle.Preferably, the sensor of each magnet and a common fixed-site, especially Hall switch cooperation.Therefore detected magnetic field through sensor, made and to confirm the position.At this, preferably two preferably different ground of tack magnet are directed, the feasible situation that can confirm the position based on the direction in magnetic field.
Therefore controlling device according to the utility model is can be in order to arrive the preferably controlling device of the angle in 20 to 350 degree scopes of different amount.As previously mentioned, the controlling device of 360 degree also is fine.At this, the preferably contactless detection of the detection of angle.Through preferably with at least one tack magnet arrangement with gear that live axle is connected on, can preferably limit two final positions with simple mode.Therefore two final positions or other arbitrarily position can change according to the difference location of customer requirement through two tack magnets with simple mode.
According to preferred arrangements, promptly at least one magnet and live axle have certain distance and the layout of a magnet on live axle, can calculate existing drive gap like needs.With this, can realize strictly arriving angle.
Additional advantage according to the controlling device of the utility model is that said controlling device can be embodied as straight numerical system.Each magnet sensor only need detect two states thus.Based on changing and therefore not influencing reliability and precision according to the controlling device of the utility model based on the changes of magnetic field that external action caused of for example temperature fluctuation.
In preferred especially form of implementation, the bipolar Hall transducer that latchs is used as magnetic field sensor.Can on the tack magnet, discern rotation by means of this type of sensor.Through using other this type of the Hall transducer that detects of having realized rotating, existence can be for move acting possibility of undesirable valve.
In other preferred implementing form, use one pole Hall transducer and two to lead to magnet.At this, can detect two positions between the magnet, because Hall transducer only switches at final position.At this, realized the association of the univocality of working zone through different angles, wherein the working zone is less than remaining angular regions.
