The conveying chamber element is preferably designed in an annular manner. The transfer chamber element preferably has a slotted annular design. Viewed in a plane (in particular viewed in a plane extending at least substantially perpendicularly to the drive axis of the drive shaft), the transport chamber element has in particular a cross-sectional shape which substantially consists of a circular arc or an open ring which extends along an angular range of less than 360 °, and in particular of more than 90 °, and two lateral extensions which extend transversely to the circular arc or open ring and in particular directly adjoin the circular arc or open ring in the end region of the circular arc or open ring.

Likewise, other materials deemed suitable by those skilled in the art are also contemplated.
The conveying element preferably has a base body. The base body has in particular an annular design. The transport side of the base body is preferably arranged on the side of the base body facing away from the actuating side of the base body. The conveying side forms in particular the outer side of the base body. The actuation side preferably forms the inner side of the base body. The at least one actuation extension of the transport element is preferably arranged on the actuation side.

In particular for generating a vacuum in the transport chamber, the transport element (in particular the transport membrane) can advantageously be moved away from the counter surface of the transport chamber element, in particular lifted from the counter surface, under the action of a drive force acting in a direction away from the actuating side. In particular a vacuum of less than-0.1 bar, preferably less than-0.2 bar, in particular less than-0.3 bar (in particular atmospheric pressure around the conveying device) can preferably be generated as a result of the movement of the conveying element (in particular the conveying film) away from the opposite surface. This makes it possible to advantageously convey the medium to be conveyed into a conveying chamber of the conveying device, which conveying chamber is at least partially delimited by the counter surface and the conveying surface.
The transport element, in particular the transport membrane, can preferably be driven by a drive unit such that transport of the medium to be transported, in particular a fluid, can be achieved according to the traveling wave principle (see for example the disclosure of EP 1317626B 1). The drive unit may be designed in the form of a mechanical drive unit, a magnetic drive unit, a piezoelectric drive unit, a hydraulic drive unit, a pneumatic drive unit, an electric drive unit, a magnetorheological drive unit, a carbon nanotube drive unit or a combination of drive units of the above-mentioned type or in the form of different drive units as deemed suitable by the person skilled in the art. The drive unit preferably has at least one drive element for acting on the transport element (in particular the transport film). However, it is also conceivable for the drive unit to have more than one drive element for acting on the conveying element. The drive element is preferably used to elastically deform the transport element (in particular the transport film) when a driving force acts on the transport element (in particular the transport film). The drive element may have any design deemed suitable by the person skilled in the art, for example in the form of a plunger, an extension, an engagement ring, a hook, a clamping element, etc. The drive element is preferably designed in the form of an eccentric shaft. Preferably, the motor unit of the pump comprising the delivery device may drive the eccentric shaft in a rotary manner by means of a motor in a manner familiar to the person skilled in the art. The motor unit may be designed in the form of an electric motor unit, an internal combustion engine unit, a hybrid motor unit or the like. The drive element preferably has an axis of rotation. The axis of rotation preferably extends transversely, in particular at least substantially perpendicularly, to a main conveying direction of the conveying chamber, along which the fluid can be conveyed through the conveying chamber.
The transport chamber of the transport device is preferably delimited by the base body of the transport element and the transport chamber element. The transport chamber of the transport device is preferably delimited by a transport surface and an opposite surface opposite the transport surface. The transport chamber element is preferably designed in a dimensionally stable manner. The conveying chamber element preferably has a prestress, in particular for exerting a force on the conveying element in the direction of a drive unit and/or a pressing unit of the conveying device. The conveying element, in particular the conveying film, is preferably designed in an elastic manner. The term "elastic" particularly refers to the property of an element (particularly a conveying element) which serves in particular to generate a reaction force which depends on (and preferably is proportional to) a change in the shape of the element and counteracts the change. The transport element (in particular the transport film) can preferably be repeatedly deformed without, in particular, mechanically damaging or destroying the transport element (in particular the transport film) as a result. The transport element (in particular the transport film) preferably strives to automatically resume a basic shape, in particular a convexly curved basic shape with respect to the opposite surface, in particular a zero position of the transport element (in particular the transport film), in particular after deformation. The elastic design of the transport element, in particular of the transport membrane, can preferably be influenced and/or formed at least partially by a specific geometric design of the base body and/or by arranging the transport element, in particular of the transport membrane, on a transport chamber element having opposing surfaces. The transport element (in particular the transport membrane) is preferably arranged on a transport chamber element having opposing surfaces such that the fluid is transported in and/or through the transport chamber due to the recess of the transport element (in particular the transport membrane). After the driving force has ceased to act on the transport element, in particular the transport membrane, for the purpose of transporting the fluid, the transport surface of the transport element, in particular the transport membrane, preferably seeks to resume the convex curved arrangement relative to the counter surface in an at least substantially automatic manner, in particular due to the elastic design. The conveying elements, in particular the conveying film, are preferably made of rubber-like and/or natural rubber-like material. However, it is also conceivable that the conveying means, in particular the conveying film, is composed of a different material or a combination of materials, which is considered suitable by the person skilled in the art, which enables a resilient design of the conveying element, in particular of the conveying film. The transport element, in particular the transport membrane, preferably utilizes a "groove effect" for transporting the fluid into and/or through the transport chamber. The conveying element, in particular the conveying surface, may preferably be at least temporarily recessed for conveying the fluid, wherein the at least one groove may be displaced, in particular in a rolling manner, along the conveying surface for conveying the fluid.
The design of the present invention advantageously allows for a longer service life. The relative motion that is inadvertently generated can be advantageously counteracted. The sealing function can advantageously be maintained during the relative movement. Efficient transport of fluid can advantageously be achieved. A very high ease of maintenance can advantageously be achieved. An adaptation to different connection options can advantageously be achieved. An easy connection to fluid conduits of different designs can advantageously be achieved. A wide range of applications for efficient fluid transport can advantageously be achieved.
Furthermore, the invention provides that the conveying device comprises at least one functional unit (in particular a filter unit and/or a valve unit) and a fluid supply line connection and/or a fluid discharge line connection, wherein the functional unit is arranged at least partially in the fluid supply line connection and/or the fluid discharge line connection. The functional unit is preferably designed in the form of a filter cartridge and/or a valve cartridge which is integrated into the fluid supply line connection and/or the fluid discharge line connection. The functional unit is arranged in particular in a replaceable manner in the fluid supply line connection and/or the fluid discharge line connection. However, it is also conceivable for the functional unit to be permanently integrated into a fluid supply line connection and/or a fluid discharge line connection, wherein the fluid supply line connection and/or the fluid discharge line connection are designed in an exchangeable manner in order to exchange the functional unit. The design of the invention makes it possible to integrate additional functions into the delivery device in a structurally simple manner. Efficient transport of fluid can advantageously be achieved.
Furthermore, the invention provides that the connecting elements and/or in particular the additional connecting elements are each arranged on at least one lateral extension of the conveying chamber element. The connecting element and/or in particular the additional connecting element is preferably arranged in each case on at least one lateral extension of the transport chamber element, in particular designed in one piece with the respective lateral extension. The term "integrally" refers in particular to at least a firmly bonded connection (produced, for example, by a welding process, a bonding process, a two-shot molding process and/or a different process deemed suitable by the person skilled in the art) and/or to advantageous integral manufacture (produced, for example, from a casting and/or in a single-or multi-component injection molding process and advantageously from a single blank). The design of the invention advantageously makes it possible to achieve a structurally simple connection interface which can be sealed in a structurally simple manner. Additional functions can be integrated into the conveying device in a structurally simple manner. Efficient transport of fluid can advantageously be achieved.

The pressing unit 96 has at least pressing elements 98, 100 (in particular at least a clamping ring), wherein the conveying element 22 has at least the sealing extension 90, and wherein the pressing elements 98, 100 press the sealing extension 90 against the conveying chamber element 20, in particular at least in the circumferential direction of the conveying chamber element 20, in particular with an uneven pressing force in the circumferential direction. The pressing unit 96 has at least one pressing element 98, 100 (in particular at least a clamping ring) having a pressing surface 104, wherein the pressing surface has a varying height (in particular a varying distance from a surface (in particular an inner surface) of the pressing element 98, 100 facing the pressing surface 104) along a maximum longitudinal extent of the pressing surface 104, in particular extending in the circumferential direction of the pressing element 98, 100). The varying height of the compacting surface 104 is preferably formed by different maximum heights of the compacting surface 104 in the circumferential direction. As an example, fig. 9 shows in phantom three different locations 106, 108, 110 on the compression element 98 where the compression surface 104 is used to create different degrees of compression of the seal extension 90. The pressing surface 104 has in particular at three different positions 106, 108, 110 different maximum heights, which can be formed in various ways, for example by varying the maximum thickness of the pressing element 98 at the three positions 106, 108, 110 compared to the other positions of the pressing element 98, by varying the geometrical extent of the pressing surface 104 on the side of the pressing element 98 facing the conveying element 22 or in different ways as deemed appropriate by the person skilled in the art. For example, due to the varying heights, the seal extension 90 is compressed to varying degrees at locations 106, 108, 110. For example, at location 106, seal extension 90 is compressed, in particular, by more than 10%, preferably more than 15%, in particular more than 20%, in particular more than 22% of maximum thickness 68 of seal extension 90. For example, at location 108, seal extension 90 is compressed, in particular, by more than 5%, preferably more than 10%, in particular more than 15%, in particular more than 19%, of maximum thickness 68 of seal extension 90. For example, at location 110, seal extension 90 is compressed, in particular, by more than 4%, preferably more than 8%, in particular more than 14%, in particular more than 16% of maximum thickness 68 of seal extension 90.
The pressing unit 96 has at least one pressing element 98 (in particular at least one clamping ring) and at least one additional pressing element 100 (in particular at least one additional clamping ring), wherein the conveying element 22 is designed in an annular manner and is pressed against the inner circumference of the annular conveying chamber element 22 by means of the pressing element 98 and the additional pressing element 100, and wherein the pressing element 98 and the additional pressing element 100 are arranged on the conveying element 22 on opposite sides of the conveying element 22. The pressing element 98 and the additional pressing element 100 of the pressing unit 96 preferably have an at least substantially similar design. The pressing element 98 and the additional pressing element 100 are arranged mirror-symmetrically on the conveying chamber element 20 in order in particular to press the conveying element 22 against the conveying chamber element 20 and to press the sealing extension 90 into the sealing groove 88. The conveying chamber element 20 has at least one groove (preferably a sealing groove 88) which extends in particular along the inner circumference of the annular conveying chamber element 20 and into which in particular at least the sealing extension 90 of the annular conveying element 22 is pressed by means of a pressing element 98 (in particular a clamping ring) and/or by means of an additional pressing element 100 of a pressing unit 96, wherein the sealing extension 90 is compressed unevenly along the largest longitudinal extent of the sealing extension 90 (in particular in the circumferential direction of the conveying element 22). As an alternative or in addition to the varying height of the pressing surface 104 of the pressing element 98 and/or of the additional pressing element 100, it is conceivable for the conveying element 22 to have at least a sealing extension 90 which is pressed against the inner circumference of the annular conveying chamber element 20 by the pressing unit 96 and has a varying maximum thickness 68 along the maximum longitudinal extent of the sealing extension 90 (in particular in the circumferential direction of the conveying element 22). Likewise, different designs of the pressing unit 96 for producing an uneven compression of the sealing extension 90 in the circumferential direction in the sealing region 102, which is deemed suitable by the person skilled in the art, can be envisaged.
