Definitions
- the invention relates to a valve opening mechanism.
- Valves are used in numerous technical fields required to shut off or meter fluid flows. For example, it is in the field of automotive engineering usual, a to reduce pollutant emissions To recirculate the exhaust gas to the fresh air is used with the fuel to form a mixture. in this connection is usually a regulation of the returned Exhaust gas quantity depending on the operating state of the engine performed. Valves are required for this regulation. This applies to numerous other applications, for example in the field of automotive engineering and here for example, to shut off an exhaust gas flow, the is not returned, but to an exhaust system arrives where one or more switching flaps are provided are to or to resonators or coolers in front of catalysts off.
- EP 1 199 463 A2 describes a rotary drive for an exhaust gas recirculation valve known that a flywheel has, with a driving element of the rotary drive can be brought into and out of engagement with the valve element is at least indirectly connected resiliently and after disengagement of the driving element with the Valve element can be brought into engagement at least indirectly in this way is that a shock is transmitted.
- the invention has for its object a valve opening mechanism to create with simple design, by means of whose opening of a valve is then also reliably possible is when there are unusually high opening forces in individual cases are required, for example if the valve in the closed state is glued.
- this has a motor with one on the one hand rotatable motor shaft.
- This engine can from be of any design.
- it can be one electric drive, for example in the form of a Electric motor, again for example a stepper motor, a so-called torque motor or a rotary solenoid, and one hydraulic or pneumatic rotary drive.
- the rotating motor shaft is a so-called rotating part connected. This rotating part is used to open the valve the motor shaft rotated.
- actuating part provided that rotatable and eccentric on the rotating part stored and resiliently connected to this.
- Words is on the rotating part with respect to the motor shaft eccentrically a bearing for the operating part, for example a bearing bush protruding from the turned part, intended.
- the actuating part is on this bearing rotatably mounted.
- There is also a resilient connection which the position of the rotating and operating part to each other Are defined.
- This arrangement normally acts in such a way that the power of the motor from the rotating part through the resilient Connection is transferred to the actuator in such a way that this is rotated and an opening of the valve can effect.
- the valve is in its seat stick, can be applied by the actuator Not enough force to open the valve.
- the Valve therefore does not change its position, and that in suitably connected actuator moves not either.
- the valve opening mechanism according to the invention thus enables, even if the There is a risk of a valve sticking to its seat or is liable, it can be opened reliably.
- the transmitted via the eccentric bearing increases Force corresponding to the angle of rotation of the motor. That power builds up slowly and reaches its maximum when the Maximum eccentricity is used. Once under this Force build-up is the force that is required to release the Valve is required, this loosening and the resilient connection between the rotating and operating part causes the twist of the two components with respect each is returned to the initial state.
- valve opening mechanism in particular Suitable for, but not limited to, use as a valve that either opens an exhaust gas flow or blocks or regulates it.
- valve opening mechanism according to the invention also in Connection with an exhaust gas flow at various points be used.
- the valve opening mechanism according to the invention be provided in an area where intake air and Exhaust gas already mixed leaves the valve housing.
- the valve opening mechanism is applicable to Arrangements in an exhaust system in which one or more Valves can be provided, for example, in the cooler Area of catalysts or resonance bodies too or off.
- valve opening mechanism according to the invention also in the field of automotive engineering or can be used in other technical fields and unfolds its advantages especially when fluids, ie any liquids or gases flow through a valve, which are such that there is a risk of sticking or the valve sticks to its seat.
- the valve opening mechanism according to the invention can also be used with any fluids if it is in certain situations may be desired, an extreme to apply excessive opening force to the valve.
- valve for the invention irrelevant. Basically, there is a rotational movement of the Rotary and the actuating part. This can be used to operate a valve between the opening and Closed position is rotated, for example Flap valve.
- the invention is based on a globe valve applicable by between the rotating actuator and the valve element to be moved in translation suitable power transmission mechanism is provided.
- the eccentric bearing of the Actuating part executed on the rotating part such that the eccentric bearing when the motor shaft rotates, assuming the valve is closed, is moved at least slightly in the opening direction.
- the desired effect is particularly reliable reachable.
- the eccentricity of the bearing has Actuating part on the rotating part with respect to the motor shaft pointed out that this is a comparatively low Eccentricity is sufficient.
- This can be particularly in the area from 0.1 to about 1 mm and preferably about 0.3 mm.
- the rotating part has eccentric pin
- the actuator with is provided with an elongated hole extending in the circumferential direction, in which the pen is guided.
- the actuator takes place in the Normally the actuation of the actuating element via the resilient connection between the rotating part and the actuating part.
- it must Turn the rotating part with respect to the actuating part.
- Eccentric pin provided in the elongated hole of the rotating part Actuating member.
- the eccentricity of the pin can Range of a few millimeters or centimeters.
- the resilient connection it is preferred for the resilient connection that they are between the pin of the rotating part and the Actuating part is formed.
- the Actuating part can also be provided a pin, and a The torsion spring is approximately aligned with the axis Motor shaft aligned and anchored to the two pins.
- a lift valve can be a suitable one Power transmission mechanism may be provided.
- one Valve to be actuated by turning for example a flap valve
- it is preferred that the actuator with the valve via a lever drive connected is. This can be a further over or Reduction of the applied by the actuator Force take place and advantageously for one reliable operation of the valve used become.
- This lever mechanism can advantageously be self-locking. This is detailed below Described with reference to the figures. Essentially it will the lever drive designed such that one on the Lever drive from the side when the valve is closed the force applied by the valve tends to the engine, or generally the rotary drive, in the closing direction of the Valve to twist, or because of a missing Lever arms, no torque of any kind. In any case, a self-locking drive would the described situation no rotation of the motor in the Generate opening direction of the valve.
- the line of action of a lever in closed state through the center of the motor axis run so that one applied in the closed state Force generates no torque on the engine.
- Figure 1 is based on the exploded view basic structure of the valve opening mechanism according to the invention recognizable.
- An invisible engine drives a rotating part 10, which during the Opening process by an angle of, for example, about 70 ° emotional.
- the turned part consists of essentially from a disc 12, on the one hand, at least slightly eccentric, a bearing bush 14 for Storage of an actuator 16 is attached.
- the bearing bush 14 has an eccentricity between their inner bore and their outer diameter.
- the positioning of the bearing bush 14 on the rotating part 10 is chosen so that when rotating the rotating part 10 due to the eccentricity is a displacement of the actuating part 16 he follows. This is achieved by the fact that for the Storage of the actuator 16 responsible Outside diameter of the bearing bush 14 due to its Eccentricity with respect to the inner bore moved accordingly becomes.
- the rotation of the Rotating part 10 during the opening movement (according to FIGS. 2 to 4) counterclockwise shift of the Outside diameter of the bearing bush 14 in that direction, in which the valve can be opened.
- When aligning according to the figures show the direction Left. Because the storage of the actuator in this Moving in the direction also shifts Actuating part itself and all levers associated with it in this opening direction of the valve.
- the operating part 16 is essentially also disc or plate-shaped, it being in the shown Example has an extension 20 which in the shown Embodiment for the explained in more detail below Lever mechanism 22 is used.
- the actuator 16 has an opening 24, in which in the assembled state the bearing bush 14 is received.
- a securing element 26 is intended to allow the movement of the Actuating part 16 on the bearing bush 14 in the axial direction limit.
- the actuator 16 is due, however the possibility of rotation about the bearing bush 14 with respect of the rotating part 10 rotatable.
- the pin 18 protrudes a little over the surface of the actuator 16 and offers in the case shown in the form of a circumferential groove 30 a Anchoring possibility for a torsion spring 32, which for a resilient, rotatable connection between the rotating part 10 and actuator 16 provides.
- a spiral spring trained torsion spring 32 at their respective ends in suitably bent in a hook shape, on the one hand to the Pin 18 of the rotating part 10 and on the other to another, on the actuating part 16 provided pin 34 anchored become.
- the one that occurs when actuated Rotation of the actuator 16 is not immediate for the Opening of a valve used. Rather, that points Actuating part 16 in the area of the extension 20 Bearing pin 36 for the rotatable mounting of a lever 38.
- the lever 38 is on the bearing pin 36 by a Securing element 40 fixed.
- the Lever 38 in the same way by means of another Securing element 42 on a bearing pin 44 Connection piece 46 fixed.
- the connector 46 is at the case shown via an opening 48 with a Flap valve connected.
- the axis of rotation of the Flap valve inserted into this opening 48, and a rotation of the connecting part 46 causes a rotation of the axis of the flap valve and thus opening or closing the valve.
- Fig. 2 shows a top view of the valve opening mechanism in an installation situation.
- the Valve opening mechanism in the area of a (not too recognizing) valve is provided, which in a pipe section 50th is used, with suitable flanges 52 with others Pipe pieces is connected.
- a flap valve Through a flap valve, the Axis in the case shown perpendicular to the plane of the drawing 2 extends, the recirculated exhaust gas stream can and be switched off and regulated.
- 2 is the shown closed state of the valve. In this situation is the extension 36 connected to the lever 38 of the Actuating part approximately between the 2 and 3 o'clock position.
- the pin 18 guided in the elongated hole 28 lies against that End of the slot 28 at, which is in the direction of Clockwise.
- the torsion spring 32 is more common Way biased at best.
- the one with the valve connected connector 46 is approximately between the 1 and 2 o'clock position.
- 3 is the Situation shown where the eccentricity of the bearing of the actuating part is maximum, and thus to the maximum Power leads.
- the opening movement is done by turning the Motor shaft causes, as shown in FIG. 3 counterclockwise.
- the force of the motor shaft of the Rotating part 10 via the pin 18 and the spring 32 in such a way that Actuating part 16 transmit that this is normally also rotated counterclockwise, and by means of of the lever mechanism 22 a rotation of the connecting part 46 and thus the valve, also counterclockwise, is effected. 3, however, shows what happens if the valve sticks to its seat.
- the connecting part 46 that is firmly attached to the adhesive valve, not emotional. As a result, a movement of the Lever mechanism 22 and a rotary movement of the Actuating part 16 prevented. Because of the resilient Connection between the actuating part 16 and the rotating part 10, however, there is no blockage of the turned part 10. This rather, turns against the force of the torsion spring 32 and tensions it.
- the eccentricity of the bearing bush 14 is in the range of the upper right quadrant according to FIG which is at least slightly different in the case shown left moving storage of the actuator 16 this also moved to the left, which is shown in the drawing by the maximum offset a is indicated.
- This offset is a due to the comparatively slight eccentricity of the Bearing bush 14 also low, but goes with one comparatively extensive rotary movement of the rotating part 10 (in the case shown about 70 °), so that an extreme high gear ratio is given, and an extreme high force is generated. With this force, it follows 3 moving actuator 16 left the lever 38 also to the left, who as part of this movement Connecting part 46 and thus the valve to an extreme small angular range b, but with an extremely high one Power, twisted.
- lever mechanism for the principle of the invention is irrelevant, and can also be omitted or with another gear ratio can be formed.
- the rotary movement of the actuating part 16 can also be used to actuate a globe valve.
- the one in In case of sticking offset a, when applying an extremely high force, can also do this with a globe valve be used to detach it from its bond, and the further movement of the actuating part 16 from the in 3 shown situation in the shown in Fig. 4 Situation can lead to further, "ordinary" opening of a Lift valve are used.
- the in the operating part 16 provided opening 24 for receiving the bearing bush 14th is chosen so large that a rotation of the Actuating part 16 approved with respect to the bearing bush 14 becomes.
- the slot 28 for receiving the pin 18th can be concentric with the opening 24 in the actuating part 16 run to the necessary relative rotation between the Allow rotary 10 and the actuator 16.
- the slot can be made a little wider than the Diameter of the pin guided therein 18. Due to the described relationships, the pin 18 moves together with the rotating part 10 in the circumferential direction around the motor shaft, while the actuator 16 is about the eccentric Storage 14 rotates. There is therefore a shift of Actuating part 16 with respect to the pin 18, thereby Can be taken into account that the slot 28 for Inclusion of the pen is designed accordingly wide.
- the eccentricity of the mounting of the actuating part 16 with regard to the motor shaft it can generally be said that these are at least substantially perpendicular to one direction is formed in which is used for actuation Section of the operating part within the scope of the operation should move. At least the eccentricity has one Component in this direction.
- a Actuation takes place in that the bearing pin 36 in Frame of actuation according to the figures moved to the left, in this direction on the lever 38 "pulls" to thereby the Valve to operate.
- the eccentricity of the bearing of the Actuator 16 is at least in the initial state a certain proportion perpendicular to this direction, according to the Figures trained upwards.
- valve in the closed state can be designed self-locking.
- the valve itself can be executed eccentrically that a gas pressure on the closed valve applies such a torque that an opening movement of the valve can take place. That can one can be counteracted by a biased one Spring constantly applies a closing force to the valve.
- Lever mechanism can connect through the connecting line Centers of the two bearing pins 36 and 44, that is Direction of the lever 38 can be chosen such that it runs at least almost through the axis of the motor shaft or if a force is exerted, a rotation of the motor at most generated in the closing direction.
- the connecting line through the Center points of the bearing pins 36 and 44 at least slightly runs above the motor shaft in the bearing bush 14 is included. So when on the valve, for example by a gas pressure, in conjunction with an eccentric Bearing the valve a force in the opening direction is applied, the lever 38 pushes to the left and can the actuating part 16 a torque in the opening direction, namely apply counterclockwise.
- a force acting in the closed state brings thus no opening torque on the motor in the case shown on.
- self-locking can be achieved that the line of action 54 in the closed state 5 below the center of the motor shaft runs. If now in the closed state on the part of a closed valve acts on the lever 38, This force "wants” the actuating element 16 in the direction twist clockwise, what with the closing direction matches. The engine thus turns at most Closing direction, and there is no risk that the valve when a gas pressure is applied to the closed one Valve opens by itself.
