Summary of the Invention
Problems to be Solved by the Invention
[0005] The problem of the present invention is to provide an air vent that can achieve particularly advantageous adjustability by particularly advantageous means, and a vehicle equipped with at least one such air vent.
Means for Solving the Problems
[0006] The above problems are solved by an air vent having the features of claim 1 and a vehicle having the features of claim 10. Advantageous embodiments including preferred developments of the present invention are described in the other claims.
[0007] A first aspect of the present invention relates to an air vent for ventilating the interior of a vehicle, also referred to as a cabin or passenger compartment. This means that a vehicle, preferably designed as a motor vehicle, in particular a passenger car, in a fully manufactured state preferably has an air vent arranged in the interior. In particular, the interior is formed by the structure of a vehicle designed, for example, as a monocoque body (selbsttragende Karosserie). Ventilation of the interior should be understood as air being supplied to the interior and thus the above-mentioned air being introduced into the interior. For this purpose, air can flow through the air vent. The air vent has a housing, also referred to as an outer housing, and for ventilating the interior, the above-mentioned air can flow through the housing. This means that during operation of the air vent, air flows through the air vent and the air vent introduces air into the interior, thereby ventilating the interior. This means in particular that the air flowing through the air vent or the housing and flowing out of the air vent or the housing flows into the interior. For this purpose, the air vent has, for example, an outlet opening, and the air flowing through the housing and thus through the air vent can flow through this outlet opening, whereupon the air flowing through the outlet opening and thereby flowing out of the air vent, in particular the housing, flows into the interior. In particular, the outlet opening is an opening of the housing, whereby, for example, the outlet opening is defined directly by the housing. In particular, the outlet opening is defined directly over its entire circumference along its circumferential direction. In that case, in particular, it is conceivable that the housing ends at the outlet opening, in particular facing the interior.
[0008] The air vent has a flow body (Stroemungskoerper), also referred to as an inner body, which is arranged within the housing and, for example, formed separately from the housing. The air flowing through the housing can flow around the flow body, particularly on the outer peripheral side. This means that the flow body has an outer jacket surface on the outer peripheral side through which the air flowing through the housing can flow around the surroundings, particularly directly. For example, the outer jacket surface on the outer peripheral side of the flow body faces the inner jacket surface on the inner peripheral side of the housing. For example, the air passage of the housing, and thus the air vent, is particularly directly defined by the inner jacket surface on the inner peripheral side of the housing, and the air supplied to the interior can flow through the air passage and thus through the housing.
[0009] Furthermore, the air vent has a guide flap, also referred to as an adjustment flap or simply a flap, which is arranged upstream of the flow body and is movable relative to the housing and the flow body. By using the guide flap, particularly by moving the guide flap relative to the housing, preferably relative to the flow body, the outflow direction in which air flows out of the air vent and particularly simultaneously into the interior can be adjusted, i.e., it can be changed or altered. The feature that the guide flap is arranged upstream of the flow body means that the air flowing through the housing, particularly through the air passage, flows first to the guide flap and around it on the way to the interior of the housing, particularly towards the outlet opening, and then around the flow body. By flowing to the guide flap and around it on the way for the air flowing through the housing towards the interior, for example, the air can be directed, diverted, or deflected by the guide flap, thereby adjusting the outflow direction.
[0010] The above-mentioned outlet opening of the air vent extends, for example, on a first plane, also referred to as an outlet plane. For example, the housing has an inlet opening through which air can be introduced into the housing, particularly into the air passage. For example, the inlet opening extends on a second plane, also referred to as an inlet plane. In that case, it is conceivable that the first plane and the second plane are spaced apart from each other and extend parallel to each other.
[0011] Next, in order to enable the particularly advantageous adjustability of the air vent to be achieved by particularly advantageous, particularly low-weight and low-cost means, according to the invention, the fluid is translatable with respect to the housing, preferably also with respect to the guide flap, whereby the flow cross-section of the air vent arranged in the housing through which air can flow is intended to be adjustable, i.e. variable or changeable. In particular, the above-mentioned flow cross-section is the narrowest flow cross-section of the air vent through which air can flow on its way through the air vent. The feature that this flow cross-section can be adjusted by translating the fluid with respect to the housing, preferably also with respect to the guide flap, is to be understood as meaning that the flow cross-section can be selectively enlarged or reduced by translating the fluid with respect to the housing, preferably also with respect to the guide flap. By adjusting the flow cross-section, for example, the amount of air supplied to the interior can be adjusted as required. Furthermore, for example, by adjusting the flow cross-section, the so-called throw distance (Wurfweite) or injection distance (Einwurfweite) of the air can be adjusted. The throw distance or injection distance is to be understood as the section distance through which the air flowing through the air vent, in particular from the air vent or from the outlet opening, flows into the interior. Therefore, according to the invention, since it is possible to adjust the flow cross-section, and thus the amount of air supplied to the interior, and / or the throw distance of the air supplied to the interior via the fluid, for example, an additional regulating flap or closing flap for closing the air vent in particular can be omitted, whereby the number of parts of the air vent, and thus the weight and cost, can be kept particularly low. Therefore, the air vent, and thus, for example, the amount of air supplied to the interior and / or the throw distance of the air supplied to the interior, can be adjusted in a space-saving and low-cost manner. The translatability of the fluid with respect to the housing enables, for example, a particularly advantageous visual effect of the air vent, in particular its function, to be achieved, in particular, for example, by the end face of the fluid facing the interior being visually perceptible by the passengers in the interior, in particular via the outlet opening.
[0012] For example, by causing a fluid to translate with respect to a housing, at least two different values of the flow path cross-section can be set. The first value of the values is, for example, zero or greater than zero, and the second value of the values is greater than the first value, for example. By setting the second value, for example, a greater amount of air flows into the room than when setting the first value of the flow path cross-section, and / or the range distance becomes longer. For example, by setting the first value, the flow path cross-section can be fluidly blocked, particularly when the first value is zero, thereby preventing air from flowing through the air vent and thus preventing air from flowing into the room through the air vent or avoiding the above-mentioned air flow. In particular, the air vent can adjust, i.e., change, the flow rate by adjusting the flow path cross-section. For example, air can flow out of the air vent at the above-mentioned flow rate and into the room, particularly through the outlet opening. In particular, the range distance can be adjusted, i.e., changed, thereby.
[0013] In one embodiment of the present invention, for ventilating a room, air can flow through the housing in a specific flow direction, at least upstream of the guide flap. This means that the air flowing through the housing, particularly the air passage and thus the air vent, has the above-mentioned flow direction at least upstream of the guide flap. This aforementioned flow direction is also referred to as the first flow direction. For example, the air is directed, redirected, or deflected by the guide flap, thereby adjusting the outflow direction, also referred to as the exit direction for example. Therefore, the air is considered to have a second flow direction downstream of the guide flap that is different from the first flow direction, particularly extending obliquely or perpendicularly to the first flow direction. Thereby, for example, the air flows through the housing, particularly the air passage, in the second flow direction downstream of the guide flap. In that case, in particular, it is conceivable that the first flow direction extends perpendicularly to the exit plane and, for example, also perpendicularly to the inlet plane. In particular, the first flow direction coincides with the axial direction of the housing and thus the entire air vent. The outlet opening and / or the inlet opening are circular and thus, for example, can have the shape of a circle centered in the axial direction of the housing and thus the entire air vent. In particular, the first flow direction is straight and thus extends, for example, along a straight line where the above-mentioned center point is located. In the following, unless otherwise specified, the term "flow direction" should be understood as the first flow direction.
[0014] In another embodiment of the present invention, in order to enable the adjustment, i.e., the change, of the flow path cross-section, particularly as needed and by particularly low-cost means, the flowing body can move translationally back and forth with respect to the housing, preferably also with respect to the guide flap, along the flow direction and thus preferably in the axial direction of the entire housing and air vent. Thereby, the flow path cross-section can be adjusted, i.e., changed.
[0015] Another embodiment is characterized in that the fluid body is rotationally symmetrically formed on the outer peripheral side over at least a major length of the fluid body, thus along the flow direction, and thus over at least more than half of the length extending in the axial direction of the air vent. In particular, it should be understood that the aforementioned outer jacket surface of the fluid body on the outer peripheral side is rotationally symmetrically formed over at least the major length of the fluid body extending along the flow direction. Thereby, air can be supplied into the room by an advantageous means especially in terms of flow.
[0016] In order to enable particularly advantageous adjustability of the air vent, in another embodiment of the present invention, the guide flap is pivotable with respect to the housing and with respect to the fluid body about a pivot axis extending perpendicular to the flow direction, whereby the outflow direction is intended to be adjusted. The feature that the pivot axis extends perpendicular to the flow direction should be understood such that the flow direction extends perpendicular to the flow plane, and the flow plane extends parallel to or coincides with the outlet plane, for example. The pivot axis extends perpendicular to the pivot axis plane, and the flow plane and the pivot axis plane extend perpendicular to each other.
[0017] Another embodiment is characterized in that the guide flap is rotatable with respect to at least one housing part of the housing and with respect to the fluid body about a rotation axis that coincides with the flow direction, thus the axial direction of the entire housing and the air vent, whereby the outflow direction is adjusted. Thereby, particularly extensive adjustability of the air vent or the outflow direction can be provided by particularly low-cost means.
[0018] In another embodiment of the present invention, in order to rotate the guide flap particularly as needed and easily about the axis of rotation, and thus to be able to adjust the outflow direction as needed, it is contemplated that the housing has at least one housing part as a first housing part coupled to the guide flap. Further, the housing has a second housing part arranged, for example, upstream or downstream of the first housing part. The first housing part, and the guide flap together with the first housing part, are rotatable about the axis of rotation with respect to the second housing part and with respect to the fluid. In particular, for example, the first housing part is formed as a ring, also called an adjustment ring or an outer ring, and through this ring, the guide flap can be rotated about the axis of rotation as needed and advantageously, particularly by the rotation of the ring performed with respect to the second housing part.
[0019] In another embodiment, in order to achieve a particularly wide adjustability of the air vent in a particularly low-cost manner, a coupling device is provided that couples the fluid and the guide flap to each other such that both the fluid and the guide flap can be moved by exactly one electrically operable actuator. In particular, the actuator may be part of the air vent. Through the coupling device, the actuator can, for example, actuate both the fluid and the guide flap, thereby, for example, displacing the fluid translationally with respect to the housing and moving, particularly pivoting and / or rotating, the guide flap with respect to the housing. This can ensure a particularly low-cost structure of the air vent.
[0020] Furthermore, it has been found to be particularly advantageous when the inner peripheral side of the housing is rotationally symmetrically formed at least in the longitudinal direction region of the housing, particularly when the fluid is arranged in the longitudinal direction region. This can provide an advantageously flowing supply of air into the room.
[0021] By translating the fluid relative to the housing, the flow path cross-section can be adjusted, for example, as follows. The fluid can be translated relative to the housing, for example, between at least two different positions and thus displaced. At a first position of the fluid, for example, a first value of the flow path cross-section is set, and at a second position, for example, a second value of the flow path cross-section is set. For example, at the first position, at least a first wall region of the fluid is disposed closer to a second wall region of the housing than at the second position, whereby, for example, at the first position, the flow path cross-section or the value of the flow path cross-section is smaller than at the second position. In particular, at the first position, the first wall region abuts directly against the second wall region, whereby, for example, at the first position, the flow path cross-section can be set to zero and thus considered closed. Further, at least at the second position, it is conceivable that the wall region directly defines the flow path cross-section. For example, it is conceivable that the second wall region tapers in the flow direction, and for example, in particular, the first wall region also tapers in the flow direction. Thereby, the flow path cross-section can be adjusted particularly advantageously.
[0022] A second aspect of the invention relates to a vehicle having at least one air vent according to the first aspect of the invention, preferably designed as a motor vehicle, in particular a passenger car. The advantages and advantageous configurations of the first aspect of the invention can be regarded as the advantages and advantageous configurations of the second aspect of the invention, and conversely, the advantages and advantageous configurations of the second aspect of the invention can be regarded as the advantages and advantageous configurations of the first aspect of the invention.
[0023] Another advantage of the present invention is that, since the guide flap is arranged upstream of the fluid, the guide flap is not visible to the passengers inside the room, i.e., it cannot be visually perceived. Therefore, the adjustment of the outflow opening, also called air deflection, can be carried out by the actual component, precisely the guide flap arranged upstream of the fluid, without being visible to the people inside the room. The guide flap is arranged behind the fluid with respect to the line of sight of a person inside the room looking at the air vent and, in particular, at the fluid at that moment, and is therefore not visible to people. Furthermore, the present invention enables at least one or a plurality of additional functions to be incorporated particularly advantageously into the fluid. For example, lighting may be incorporated into the fluid. This means that, for example, at least one light source is arranged particularly in the fluid, in particular inside the fluid, and this light source can provide light particularly using electrical energy, and the light can, for example, enter the room particularly through the outlet opening and is therefore, for example, visually perceivable by the eyes of a person inside the room. Alternatively or additionally, scenting (perfuming agent) can be incorporated into the fluid. Thus, the fluid has, for example, at least one or a plurality of outflow openings through which the scent provided by the scent source can flow. The air flowing around the fluid and through the air vent can carry the scent flowing through the outflow openings together and send it particularly into the room through the outlet opening, thereby achieving a particularly advantageous scenting (air purification) of the room.
[0024] Other advantages, components, and specific details of the present invention will become apparent from the following description of the preferred embodiments and with reference to the drawings. The features and combinations of features mentioned in the above description, as well as the features and combinations of features mentioned in the descriptions of the following figures, and / or the features and combinations of features shown only in the figures, are not used only in the presented combinations, but can also be used in other combinations without departing from the scope of the present invention, and can also be used alone.

DETAILED DESCRIPTION OF THE INVENTION
[0026] In each figure, the same elements or functions are denoted by the same reference numerals for the same elements.
[0027] FIG. 1 shows in a schematic longitudinal sectional view an air vent 10 provided in a fully manufactured state in a vehicle preferably designed as an automobile, particularly a passenger car, for ventilating an interior 12 also called a cabin or passenger compartment of the vehicle. The air vent 10, also referred to as an air nozzle or a ventilation nozzle, does not necessarily have to be formed as a nozzle in the original technical sense. The air vent 10 has a housing 14 through which air, also called interior air, flows to ventilate the interior 12. This means that during operation of the air vent 10, the above-mentioned air flows through the housing 14 and thus through the air vent 10, and in particular flows out from the air vent 10 and thus from the housing 14, and at the same time flows into the interior 12. Thereby, air is supplied to the interior 12 and thus introduced into the interior 12, whereby the interior 12 is ventilated.
[0028] The housing 14 has an air passage 16 through which air can flow, and the air passage is defined, for example, particularly directly by the outer jacket surface 18 on the inner circumferential side of the housing 14. The air vent 10 is arranged within the housing 14 and has a flow body 20 around which air can flow particularly directly. In particular, the flow body 20 has an outer circumferential side jacket surface 22, and the outer circumferential side jacket surface 22 faces, for example, particularly the inner circumferential side jacket surface 18 of the housing 14, and thus of the entire air vent 10, in the radial direction. During the above operation, for example, air flows through the air passage 16 and thus through the housing 14 and around the outer circumferential side jacket surface 22 and thus particularly directly around the flow body 20. The flow body 20 is also called the inner body.
[0029] The air vent 10 also has a guide flap 24 arranged within the housing 14, which is arranged upstream of the fluid 20. Preferably, the housing 14, the guide flap 24, and the fluid 20 are separately formed components, which can be coupled to each other, for example, at least indirectly. In particular during operation, the air flowing through the air passage 16 and thus through the housing 14 flows particularly directly to the guide flap 24, also called a flap or regulating flap, whereby, for example, the guide flap 24 changes, deflects, or diverts the direction of the air flowing through the air passage 16. Thus, by using the guide flap 24 and by the guide flap 24 moving relative to the housing 14 and relative to the fluid 20, the air flowing through the air passage 16 can be directed or deflected as required, whereby the outflow direction in which the air flows out of the air passage 10 and into the room 12 can be adjusted, i.e., changed. According to FIG. 1, the outflow direction particularly adjusted by the guide flap 24 is indicated by the arrow 26 in FIG. 1. It can be recognized that the air vent 10 has an outlet opening 28 extending on a virtual outlet plane 30. The outlet opening 28 is defined over its entire circumference along its circumferential direction and directly by the housing 14, i.e., the outlet opening 28 is an opening of the housing 14. The air passage 16 leads to the room 12 via the outlet opening 28, and during operation, air flows through the air passage 16 and the outlet opening 28 and into the room 12 via the outlet opening 28, particularly along the outflow direction or along the outflow direction indicated by the arrow 26.
[0030] In the embodiment shown in the figures, the housing 14 and thus the air vent 10 also has an inlet opening 74 through which air can be introduced into the air passage and the housing 14, particularly in a first flow direction or along a first flow direction. For example, the inlet opening 74 preferably extends parallel to the outlet plane 30 and extends on an inlet plane 76 spaced from the outlet plane 30.
[0031] Next, in a particularly advantageous manner, in order to enable particularly advantageous adjustability of the air vent 10, the fluid body 20 is translatable relative to the housing 14, preferably also relative to the guide flap 24, which is indicated by the double arrow 32 in FIG. 1. This means that the fluid body 20 can be translated back and forth relative to the housing 14, preferably also relative to the guide flap 24, particularly along the straight line indicated by the double arrow 32, and thus along the moving direction extending in a straight line, whereby the air flowing through the air passage 16 can flow through, and the flow cross-section Q of the air vent 10 arranged in the housing 14 can be adjusted, i.e., changed or altered.
[0032] In FIG. 1, the air flowing through the air passage 16, and thus through the housing 14, has a first flow direction indicated by arrow 34 at least upstream of the guide flap 24. The air flowing through the air passage 16 flows directly and especially around the guide flap 24, and can be redirected, turned, or deflected by the guide flap 24, especially away from the first flow direction. Thus, downstream of the guide flap 24, the air passage 16, and thus the housing 14, flow in a second flow direction that is different from the first flow direction, for example, extending obliquely or perpendicularly to the first flow direction. In FIG. 1, the second flow direction is exemplarily indicated by arrow 36. Since the guide flap 24 is movable relative to the housing 14, for example, the second flow direction can be adjusted and thus changed. It is conceivable to move the guide flap 24 relative to the housing 14 to a guide position where the second flow direction corresponds to the first flow direction, thus coincides with the first flow direction, or extends parallel to the first flow direction. It can be recognized from both arrow 32 and arrow 34 that the fluid 20 can move back and forth translationally relative to the housing 14 along the first flow direction indicated by arrow 34, whereby the flow path cross-section Q can be adjusted. Thus, for example, the linear movement direction indicated by both arrow 32 coincides with the first flow direction of the straight line indicated by arrow 34. In the embodiment shown in the figure, the movement direction and the first flow direction extend in the axial direction of the housing 14, and thus of the air vent 10. In other words, the first flow direction and the movement direction coincide with the axial direction of the air vent 10 or the housing 14. The axial direction of the housing 14, and thus of the air vent 10, extends perpendicularly to the outlet plane 30 as a whole. For example, as can be recognized from FIG. 2, the outlet opening 28 is circular, its center M is in the axial direction, and thus is formed in the shape of a circle on a straight line that coincides with the axial direction. In that case, in particular, the movement direction (both arrow 32) and the first flow direction (arrow 34) are also on the above-mentioned straight line.
[0033] As can be recognized from FIG. 2, for example, a person in the interior 12 can see, and thus visually perceive, the fluid body 20, and thus the end face 38 on the front side of the fluid body 20, particularly through the outlet opening 28. Since the fluid body 20 is translatable relative to the housing 14, a particularly advantageous presentation of the translational movement of the fluid body 20 and thus of the adjustment of the flow cross-section Q can be achieved.
[0034] As can be particularly well recognized from FIG. 1, the outer peripheral side of the fluid body 20 is formed rotationally symmetrically over at least its major length extending along the first flow direction and thus in the axial direction of the air vent 10. In particular, the outer jacket surface 22 of the outer peripheral side is formed rotationally symmetrically on the outer peripheral side over at least more than half of the major length of the fluid body 20 and thus extending in the axial direction of the air vent 10.
[0035] As can be recognized from FIGS. 3 and 4, the guide flap 24 extends perpendicular to the flow direction and thus perpendicular to the axial direction of the air vent 10, and thus is pivotable relative to the housing 14 and also relative to the fluid 20 about a pivot axis extending particularly in the radial direction of the air vent 10, whereby the outflow direction is adjusted. For example, a base element 40 is arranged in the housing 14. In that case, in particular, it is conceivable that the fluid 20 is translatable, and thus displaceable, relative to the base element 40, in particular along the direction of movement, whereby the flow cross-section Q is adjusted. The base element 40 has here a support region 42 formed as a projection or a pin, and the support region 42 is here formed with a cylindrical outer periphery. A support sleeve 44 is displaceably arranged on the support region 42, and thus the support sleeve 44 is displaceable relative to the housing 14 along the support region 42, in particular along the direction of movement. The lever 46 is hingedly connected to the support sleeve 44, also called a slide sleeve, and is hingedly connected to the guide flap 24. The connection point at which the lever 46 is hingedly connected to the guide flap 24 is spaced apart from the pivot axis. In particular, the guide flap 24 is supported or coupled to the housing 14 so as to be pivotable about the pivot axis relative to the housing 14. Next, when the support sleeve 44 is displaced relative to the support region 42 and relative to the housing 14, in particular along the direction of movement, the guide flap 24 is pivoted about the pivot axis relative to the housing 14 due to the lever 46 being hingedly connected to both the support sleeve 44 and the guide flap 24. FIG. 3 shows a first pivot position of the guide flap 24, and FIG. 4 shows a second pivot position of the guide flap 24. The guide flap 24 is pivotable to different pivot positions relative to the housing 14 by displacement of the support sleeve 44 and is thus movable.
[0036] Furthermore, the guide flap 24 is rotatable about a rotation axis D that coincides with the first flow direction and thus the axial direction of the air vent 10, relative to at least one housing part 48 of the housing 14, and furthermore relative to the flow body 20 and also, for example, relative to the base element 40, thereby adjusting and thus changing the outflow direction. In that case, the housing 14 has a housing part 48 as the first housing part. Thus, the housing part 48 is the first housing part of the housing 14 and is also referred to as the first housing part. The housing 14 is here formed as a ring and has a second housing part 50, also referred to as an outer ring. The housing part 50 is coupled to the guide flap 24, thereby being rotatable about the rotation axis D together with the guide flap 24 relative to the first housing part 48 and relative to the flow body 20, thereby adjusting the outflow direction. In particular, the guide flap 24 is coupled to the housing part 50 so as to be pivotable about the pivot axis relative to the housing part 50, whereby, for example, the pivot axis rotates together with the housing part 50 about the rotation axis D relative to the housing part 48. Thus, the guide flap 24 can be rotated about the rotation axis D relative to the housing part 48 into at least two different rotational positions relative to each other, thereby changing the outflow direction as required.
[0037] From FIG. 5, it can be recognized that the air vent 10 has a coupling device 52, also referred to as a kinematic mechanism, by means of which the fluid 20 and the guide flap 24 are coupled to each other such that both the fluid 20 and the guide flap 24 can be moved relative to the housing 14 by exactly one, in particular electrically operable actuator of the air vent 10, as will be explained in more detail below. When viewed in conjunction with FIG. 6, it can be recognized that the coupling device 52 has a first coupling element 54, which is formed here as a first disk, in particular a first rotating disk. The first rotating disk is rotatable relative to the housing 14 about a first coupling element rotation axis. Furthermore, the first coupling element 54 is hingedly coupled to the fluid 20 such that when the first coupling element 54 is rotated relative to the housing 14 about the first coupling element rotation axis, the fluid 20 is displaced relative to the housing 14 along the direction of movement. Thus, for example, when the first coupling element 54 is rotated in a first rotational direction about the first coupling element rotation axis, the fluid 20 is displaced in a first direction relative to the housing 14 and thus undergoes a translational movement. For example, when the first coupling element 54 is rotated in a second rotational direction opposite to the first rotational direction relative to the housing 14 about the first coupling element rotation axis, the fluid 20 is thereby displaced in a second direction opposite to the first direction relative to the housing 14. For example, these directions coincide with the direction of movement. For example, the flow cross-section Q is enlarged when the fluid 20 is moved in the first direction, while it decreases when the fluid 20 is displaced in the second direction.
[0038] The coupling device 52 further includes a second coupling element 56, which is formed here as a second rotating disk. The coupling element 56 is rotatable relative to the housing 14 about a second coupling element rotation axis, and for example, the coupling element rotation axes are spaced apart from each other and extend parallel to each other or extend inclined to each other.
[0039] From FIG. 5, it can be recognized that the second coupling element 56 has a guide mechanism 58 that includes a first guide mechanism region 60 and a second guide mechanism region 62, and the guide mechanism regions 60 and 62 are connected to each other or merge into one (ineinander übergehen). In particular, a slider 64 that can be displaced relative to the housing 14 along the direction of movement is engaged with the guide mechanism 58. While the slider 64 is still engaged with the first guide mechanism region 60, if the coupling element 58 is rotated relative to the housing 14 about the second coupling element rotation axis, in particular, for example, the first guide mechanism region 60 has a radius with its center on the second coupling element rotation axis, or is on such a circle, or extends thereon, so that, for example, the displacement of the slider 64 relative to the housing 14 does not occur. However, when the slider 64 enters the second guide mechanism region 62, and thereby, for example, the second coupling element 56 is rotated relative to the housing 14 about the second coupling element rotation axis while the slider 64 is engaged with the second guide mechanism region 62, the second guide mechanism region 62 displaces the slider 64 relative to the housing 14, in particular along the direction of movement. For this purpose, for example, the slider 64, or a partial region of the slider 64 that engages with the guide mechanism 58, slides along the wall region of the second coupling element 56 that defines the second guide mechanism region 62, so that as the second coupling element 56 rotates relative to the housing 14 about the second coupling element rotation axis, the slider 64 is displaced in a specific direction of movement relative to the housing 14 in particular.
[0040] From FIGS. 6 and 7, it can be recognized that the slider 64 is connected to the support sleeve 44, whereby the support sleeve 44 can be displaced together with the slider 64, particularly along the moving direction with respect to the housing 14. Thus, when the slider 64 is displaced particularly along the moving direction with respect to the housing 14, thereby the support sleeve 44 is displaced together with the slider 64, and thereby the support sleeve 44 is displaced along the support region 42. Thereby, the guide flap 24 is pivoted with respect to the housing 14. For example, when the slider 64 and the support sleeve 44 together with the slider are displaced with respect to the housing 14 in the first direction from the second pivoting position of the guide flap 24 shown in FIG. 2, thereby, for example, the guide flap 24 is pivoted from the second pivoting position with respect to the housing 14 to the first pivoting position shown in FIG. 3. For example, when the slider 64 and the support sleeve 44 together with the slider 64 are displaced with respect to the housing 14 in the second direction from the first pivoting position of the guide flap 24 shown in FIG. 3, thereby, the guide flap 24 is pivoted from the first pivoting position shown in FIG. 3 with respect to the housing 14 to the second pivoting position shown in FIG. 4.
[0041] The coupling elements 54 and 56 are coupled to each other, particularly in a torque transmission manner, such that by rotating the coupling element 54 about the coupling element rotation axis relative to the housing 14, the second coupling element 56 can rotate or is rotated about the second coupling element rotation axis relative to the housing 14. For this purpose, the coupling elements 54 and 56 are formed as external teeth and engage with each other, and thus have teeth 66 and 68 that engage with each other. The aforementioned actuator, which is particularly electrically operable, is coupled to or can be coupled to, for example, the coupling element 54, and thus the first coupling element 54 can be driven by the actuator, whereby the first coupling element 54 can be rotated about the first coupling element rotation axis relative to the housing 14. When the coupling element 54 is rotated about the first coupling element rotation axis relative to the housing 14 by the actuator, due to the above-described coupling between the coupling element 54 and the coupling element 56, the coupling element 56 is driven by the coupling element 54 and is thereby rotated about the second coupling element rotation axis relative to the housing 14. As long as the slider 64 engages only with the guide mechanism region 60 with respect to the guide mechanism regions 60 and 62, no pivoting of the guide flap 24 occurs while the coupling elements 54 and 56 rotate. Thus, for example, when the coupling element 54, and thus the coupling element 56, is driven by the actuator such that the slider 64 engages only with the guide mechanism region 60 with respect to the guide mechanism regions 60 and 62 and the coupling elements 54 and 56 rotate particularly simultaneously, usually the two coupling elements 54, 56 rotate simultaneously, and by rotating the coupling element 54, the fluid 20 is displaced relative to the housing 14, but at this time, no pivoting of the guide flap 24 occurs. Thus, for example, it is possible to displace the fluid 20, which is initially in the first position, in the second direction and thereby to the second position, and thus to set the flow path cross-section Q from the first value to a second value greater than the first value, while no movement of the guide flap 24 relative to the housing 14 occurs.From the second position of the fluid body 20, when the coupling elements 54, 56 are further rotated such that the slider 64 enters the guide mechanism region 62 from the guide mechanism region 60 and is moved along this guide mechanism region 62, thereby, in particular, while there is no movement of the fluid body 20 relative to the housing 14, the guide flap 24 is pivoted relative to the housing 14. Thus, for example, when the coupling elements 54 and 56 are rotated relative to the housing 14 while the slider 64 engages only with the guide mechanism region 62 with respect to the guide mechanism regions 60 and 62, the guide flap 24 can be pivoted relative to the housing 14 about the above-mentioned pivot axis by the actuator while there is no movement of the fluid body 20 relative to the housing 14. In particular, it can be recognized that each tooth 66, 68 extends only partially around each of the coupling elements 54, 56, rather than around the entire circumference of each of the coupling elements 54, 56 that extends around the respective coupling element rotation axis.
[0042] The above-mentioned pivot axis about which the guide flap 24 can be pivoted relative to the housing 14 can be recognized from FIG. 7, where it is indicated by S.
[0043] From FIGS. 8 and 9, it can be recognized that the housing part 50 has teeth 70 formed as external teeth, for example, on the axial end face of the housing part 50, particularly formed like the teeth of a ring gear. A gear 72 that is rotatable about the gear rotation axis with respect to the housing 14 is also provided. The gear 72 has gear teeth corresponding to the teeth 70, particularly like a pinion, which engage with the corresponding teeth 70. The gear rotation axis extends perpendicular (orthogonal) to the rotation axis D. In that case, when the gear 72 rotates about the gear rotation axis with respect to the housing 14, this rotation of the gear 72 is converted via the gear teeth and the teeth 70 into a rotation of the housing part 50 about the rotation axis D with respect to the housing part 48. For example, in addition to the aforementioned actuator, a second actuator, for example, an electrically operable one, is provided. The second actuator can drive the gear 72, thereby rotating it about the gear rotation axis with respect to the housing 14, whereby the housing part 50 is driven by the gear 72 and the rotation axis D rotates with respect to the housing part 48. Thereby, the guide flap 24 rotates about the rotation axis D with respect to the housing part 48. Thus, the guide flap 24 can be rotated about the rotation axis D with respect to the housing part 48 without pivoting about the pivot axis S with respect to the housing 14, and vice versa. Thereby, the rotation of the guide flap 24 about the rotation axis D and the pivoting of the guide flap 24 about the pivot axis S can be performed particularly completely and independently of each other. Thereby, the outflow direction can be adjusted particularly as required. The connection between the guide flap 24 and the housing part 50 can be recognized particularly well from FIG. 9. The pivot axis S can also be recognized.
