Description

Technical Field

[0001] This invention relates to a sealing device for a fluid channel, the sealing device having a closing body arranged in the fluid channel. The invention also relates to an airflow device having an air supply section in which at least one such sealing device is arranged. Background Technology

[0002] A device is known from German utility model specification DE 20 2010 000 678 U1, which is to be arranged on or within a through portion having at least one tubular portion, the device being provided to define a channel, wherein the tubular portion is at least partially substantially hyperboloid deformable. Summary of the Invention

[0003] The problem solved by this invention is to simplify the regulated air supply unit in a motor vehicle.

[0004] In a fluid channel closure device, the device has a closing body arranged within the fluid channel. The solution to this problem is based on the closing body comprising a base structure surrounded by an encapsulating element that can deform in a defined manner. This encapsulating element, depending on the deformation of the base structure, closes the fluid channel to varying degrees. When the base structure with the encapsulating element is in a closed position, the closing body closes the fluid channel; when the base structure with the encapsulating element is in an open position, the closing body partially releases the fluid channel. In the closed position, the closing body completely or almost completely closes the fluid channel. In the open position, the volume of the closing body within the fluid channel decreases, thereby releasing the opening cross-section or through-section of the fluid channel from the closing body. However, when the base structure with the encapsulating element is in its open position, the closing body retained within the fluid channel still has a certain volume. Therefore, when the base structure with the encapsulating element is in its open position, the fluid channel through the closing body is not completely released.

[0005] An example of a preferred embodiment of the closure device is characterized in that the base structure comprises rods of equal length, which are mounted at their opposite ends to two parallel and coaxially arranged retaining plates, the retaining plates being capable of being twisted relative to each other so that the base structure deforms in a defined manner. Thus, the base structure can deform relatively easily with the encapsulation to allow the closure device to have adjustable fluid passages. One of the retaining plates can be fixedly arranged. The other retaining plate can then be twisted with a suitable adjusting device to ensure the desired deformation of the base structure with the encapsulation. By twisting the two retaining plates relative to each other, the base structure can deform continuously with the encapsulation in a particularly advantageous manner. The twisting of at least one retaining plate relative to the other retaining plate can be done manually or directly with a suitable actuator.

[0006] Another preferred embodiment of the enclosure device is characterized in that the retaining plate is constructed as a disc. For example, the retaining plate has a disc design. This simplifies the manufacture and operation of the enclosure device.

[0007] Another preferred embodiment of the enclosure device is characterized by the rod being hinged to the retaining plate. Therefore, the enclosure device, which has a base structure that can deform in a defined manner, can be comfortably adjusted in a simple way. Thus, it is assumed that when the retaining plates are twisted relative to each other, the distance between the retaining plates changes slightly.

[0008] Another preferred embodiment of the closure device is characterized in that the rod is completely surrounded by an encapsulation between its opposite ends. This facilitates a simple method for achieving a fluid seal in the fluid passage.

[0009] Another preferred embodiment of the enclosure is characterized by the encapsulation being made of a flexible material. This achieves the desired function in a simple way. The flexible material advantageously matches the fluid flowing through the fluid channel in terms of its sealing properties.

[0010] Another preferred embodiment of the enclosed device is characterized in that the base structure in the closed position with the encapsulation element is in the form of a straight cylinder, while the base structure in the open position with the encapsulation element is in the form of a hyperboloid of revolution. For example, the rectangular through-section can be completely or almost completely closed and partially released using a simple device. The elongated base structure is arranged such that its longitudinal axis is preferably transverse to the direction of fluid flow.

[0011] Optionally or additionally, the above-mentioned problem is solved by an airflow device having an air supply section in which at least one of the aforementioned sealing devices is arranged. The airflow device is preferably arranged in a motor vehicle and is used to regulate the air inlet entering the vehicle or the air outlet leaving the vehicle. The elongated sealing device is arranged such that its longitudinal axis is preferably transverse to the airflow direction.

[0012] An example of a preferred embodiment of the airflow device is characterized in that the air supply section includes an air passage having a through-section cross-section, in which at least two enclosed devices are arranged parallel to each other. Therefore, adaptive damper control in a motor vehicle can advantageously be replaced by an airflow device.

[0013] Another preferred embodiment of the airflow device is characterized by a rectangular cross-section of the through section. Within this rectangular cross-section, multiple enclosed devices can be arranged parallel to each other. Furthermore, these enclosed devices can be arranged coaxially with each other. For example, cooling requirements in a motor vehicle can be readily adjusted using a simple device. Attached Figure Description

[0020] Figure 6 The basic structure of the enclosed device in both the open and closed positions is shown in perspective view. Detailed Implementation

[0021] exist Figures 1 to 5 In the diagram, the airflow device 1 is shown in various views and states. The airflow device 1 is used to regulate the flow of air in... Figure 3 The air supply section in the interior space of a motor vehicle is indicated by arrows 3, 4, 5, and 6. For this purpose, the airflow device 1 includes an air passage 2. For example, the air passage 2 is an air inlet or air outlet in the motor vehicle. The air passage 2 has a rectangular through-section 7.

[0022] A total of twelve enclosed devices 10 are arranged in the cross-section 7 of the through portion of the airflow device 1. The enclosed devices 10 are... Figures 3 to 5 As shown, it does not have Figure 1 and Figure 2 The encapsulation 8 is shown to make the base structure 11 arranged below the encapsulation 8 visible. The base structure 11 with the encapsulation 8 represents the closing body 20 of the enclosing device 10.

[0023] exist Figure 3In each case, three enclosure devices are arranged one above the other, and in each case, four enclosure devices 10 are arranged adjacent to each other in the longitudinal direction. The through section cross-section 7 is divided into a total of four parts: through section cross-sections 16, 17, 18, and 19, in which three enclosure devices 10 are arranged parallel to each other.

[0024] exist Figure 1 and Figure 2 The diagram illustrates how three sealing devices 10 can be used to seal and release fluid channels 9. Figure 1 In the closed position, the closing body 20 of the sealing device 10 is in its closed position. In its closed position, the closing body 20 is in the form of a straight cylinder.

[0025] Even when the closed device 10 is closed, the distance between the closing bodies 20 in their closed positions allows fluid to pass through. This possible fluid passage can be reduced by minimizing the distance between the closing bodies 20 in their closed positions to zero.

[0026] exist Figure 2 In the closed device 10, the closing body 20 is in its open position. In the open position, each of the closing bodies 20 has a hyperboloid shape. This results in a diamond-shaped opening between the two corresponding closing bodies 20 in their open position, which allows fluid to pass through.

[0027] Figure 4 and Figure 5 The basic structure 11 of the closing body 20 of the closing device 10 is shown, allowing for continuous adjustment between an open and closed position. The basic structure 11 includes rods 12 of equal length. The rods 12 are hinged to two retaining plates 13, 14, with their ends facing away from each other.

[0028] The hinge points of rod 12 are arranged circularly on retaining plates 13 and 14. This causes rod 12 to... Figure 4 The closed position of the shown enclosure 10 is arranged in a cylindrical shape.

[0029] Figure 5 This illustrates what happens when retaining plates 13 and 14 are twisted relative to each other. For example... Figure 5 As can be seen, the relative torsion of retaining plates 13 and 14 causes rod 12 to take on the shape of a hyperboloid of revolution. This results in a rhomboid opening cross section 15 between the two corresponding closing bodies in their open positions.

[0030] use Figure 1 and Figure 2 The encapsulation element 8 of the shown closure device 10 prevents undesirable passage of fluid between the rods 12 of the corresponding base 11 in the closed and open positions.

[0031] exist Figure 6 The diagram shows the base structure 11 in its closed position 21 and its open position 22, respectively, in perspective view. The double arrow 23 represents the length of the rod 12. The length 23 of the rod 12 is fixed.

[0032] Double arrow 24 represents the distance between retaining plates 13 and 14 in the closed position. The distance between retaining plates 13 and 14 in the open position 22 is indicated by double arrow 25. Due to the fixed length 23 of rod 12, there is also a difference 26 indicated by double arrows.

[0033] Difference 26 is recognized in the enclosed device for which protection is required and can be compensated for, for example, by arranging a retaining plate 14 in a recess, the size of which is designed to receive the retaining plate 14 in both the open position 22 and the closed position 21.

[0034] The retaining plates 13 and 14 preferably have a disc shape. The recesses also advantageously have a circular diameter. The double arrow 27 represents the diameter of the retaining plate 14, which is constructed as a disc.

[0035] exist Figure 6 In the diagram, a right triangle 30 with legs 31 and 32 and a hypotenuse 33 illustrates how to calculate the reduction of the distances 24 and 25 between the retaining plates 13 and 14 when twisted between the closed position 21 and the open position 22.
