Description

FLUID NOZZLE AND FLUID SYSTEM

Technical Field

The present disclosure generally relates to a fluid system, and in particular, relates to a fluid nozzle for a fluid system.

Background

Vehicles, such as automobiles, typically include multiple external panels that are connected to a frame or a chassis. One or more gaps present between such panels may be filled with a seam sealer to prevent moisture, dirt, and the like from passing through the gaps and into an engine or passenger compartment of the vehicle. Such seam sealers can also provide sound damping to the vehicle. When one or more of these panels need to be replaced, the gaps between the panels are resealed by a technician. Oftentimes, seam seals have a unique look or pattern that is associated with the original manufacturer of the vehicle. When replacing these seam seals, the technician may desire to replicate the look or pattern of the original seam seal.

The ability to replicate an original equipment manufacturer (OEM) applied seam seal may require the use of a spray applicator and materials that work in, or with, a particular type of the spray applicator. This phenomenon may require multiple spray applicators, fluid nozzles, and materials. Spray applicators are typically expensive and may be difficult to clean. Moreover, additional applicators may be needed to brush some material prior to applying a sprayed texture, or a bead pattern.

Conventionally, a dual cartridge system used for spraying a fluid mixture containing two fluid components includes a dual barrel cartridge unit or other source (e.g., five gallon pails, five fifty-five gallon drums) containing the two fluid component, a disposable static mixer which is connected to a fluid nozzle, and an air manifold which is connected to a supply of pressurized air. Alternatively, a single cartridge system used for spraying a single fluid component generally includes a single barrel cartridge unit or other source containing the single fluid component, a fluid nozzle connected to the single barrel cartridge unit, and an air manifold which is connected to a supply of pressurized air. Typically, for single cartridge systems, the static mixer is integral with the fluid nozzle. Hence, such fluid nozzles may not be usable with dual cartridge systems. Overall, fluid nozzles usable with dual cartridge systems are different in design from fluid nozzles usable with single cartridge systems, thereby increasing part numbers.

Currently, seam sealing applications require purchasing of separate fluid nozzles based on a type of application (such as, single cartridge systems and dual cartridge systems), which may lead to confusion and incorrect ordering, and may also lead to longer wait times for completing repairs. Joints and gaps are typically filled with high viscosity fluids (e.g., using a sealer) for protection against leaks of water, air, etc. For example, gaps between various external panels (e.g., hemmed flanged panels) of a vehicle may be filled with a seam sealer to prevent moisture, dirt, etc., from passing through the gaps. In downstream repair or aftermarket applications, the gaps between such panels may need to be resealed by a technician. However, technicians have a difficult time replicating, or matching, the quality of sealing originally produced through expensive machinery that are programmed to have precise specifications for pressure, flow, volume, temperature, timing, positioning, viscosity, etc.

Possibility for human error (e.g., uneven bead height, width, or uniformity) in the field or in a repair shop increases especially with inexperienced technicians. Implementation often falls short of original equipment manufacturers capabilities, and this mismatch may be easily observed, such as in a repair assessment or insurance context. Therefore, there is a need for improved techniques to reproduce sealing that do not add time or material costs to repair or aftermarket restoration practices.

Current sealant applicators are non-rotatable, i.e., have inconsistent cross-section of an outlet of the sealant applicator with change in an orientation of the sealant applicator. Further, the current sealant applicators may not allow a user to hold the sealant applicator comfortably while applying the sealant and adjust for the numerous contours and shapes of the panels on which the sealant is being applied to.

Vehicles, such as automobiles typically include multiple external panels that are connected to a frame or chassis. Gaps between these panels can be filled with a seam sealer to prevent moisture, dirt, etc., from passing through the gaps and into engine and/or passenger compartments of the vehicle. In some cases, such seam sealers may also provide sound damping to the vehicle. When one or more of the panels need to be replaced, the gaps between such panels may be resealed by a user. Furthermore, when replacing the seam seals, the user may desire to replicate a look or pattern of original seam seals.

There are a variety of seam sealers available that have different compositions and viscosities. Conventional fluid nozzles may not be suitable for use with the different seam sealers. That is, conventional fluid nozzles may be specifically designed and suitable for use with a single seam sealer product. Further, conventional fluid nozzles may be unable to replicate a look or pattern of original seam seals when not used with the seam sealer that they are specifically designed for.

Therefore, there is a need for a fluid nozzle that is suitable for use with a variety of different seam sealers having different viscosities. Further, there is a need for a fluid nozzle that is able to replicate a look or pattern of original seam seals regardless of a difference in viscosities of different seam sealers.

Joints and gaps are typically filled with a seam sealer for sealings against leaks (e.g., of water, air, etc.). For example, gaps between various external panels (e.g., hemmed flanged panels) of a vehicle may be filled with the seam sealer to prevent moisture, dirt, etc., from passing through the gaps. In downstream repair or aftermarket applications, the gaps between such panels may be resealed by a technician. However, the technicians may have difficulty replicating or matching the quality of an original sealing. In some cases, there may be a requirement of a wide and/or flat application of a material of the seam sealer to replicate the original sealing having a wide and/or flat appearance. In such applications, tooling or brushing of the applied material in order to achieve the wide and/or flat appearance may lead to air entrapment or contamination prior to curing of the seam sealer. This may also negatively impact paint application at a later point.

Detailed Description

In the following description, reference is made to the accompanying figures that form a part thereof and in which various embodiments are shown by way of illustration. It is to be understood that other embodiments are contemplated and may be made without departing from the scope or spirit of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense.

In the following disclosure, the following definitions are adopted.

As used herein, all numbers should be considered modified by the term “about”. As used herein, “a,” “an,” “the,” “at least one,” and “one or more” are used interchangeably.

The term “about”, unless otherwise specifically defined, means to a high degree of approximation (e.g., within +/- 5% for quantifiable properties) but again without requiring absolute precision or a perfect match.

As used herein as a modifier to a property or attribute, the term “generally” or “typically”, unless otherwise specifically defined, means that the property or attribute would be readily recognizable by a person of ordinary skill but without requiring absolute precision or a perfect match (e.g., within +/- 20 % for quantifiable properties).

The term “substantially”, unless otherwise specifically defined, means to a high degree of approximation (e.g., within +/- 10% for quantifiable properties) but again without requiring absolute precision or a perfect match.

Terms such as same, equal, uniform, constant, strictly, and the like, are understood to be within the usual tolerances or measuring error applicable to the particular circumstance rather than requiring absolute precision or a perfect match.

As used herein, the terms “first” and “second” are used as identifiers. Therefore, such terms should not be construed as limiting of this disclosure. The terms “first” and “second” when used in conjunction with a feature or an element can be interchanged throughout the embodiments of this disclosure. As used herein, when a first material is termed as “similar” to a second material, at least 90 weight % of the first and second materials are identical and any variation between the first and second materials includes less than about 10 weight % of each of the first and second materials.

As used herein, “at least one of A and B” should be understood to mean “only A, only B, or both A and B”.

As used herein, the recitations of numerical ranges by endpoints include all numbers subsumed within that range as well as the endpoints (e.g., 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc.).

The term “coupled” or “connected” may include direct physical connections between two or more components, or indirect physical connections between two or more components that are connected together by one or more additional components. For example, a first component may be coupled to a second component by being directly connected together or by being connected by a third component.

Unless specified or limited otherwise, the terms “attached,” “connected,” “coupled,” and variations thereof, are used broadly and encompass both direct and indirect attachments, connections, and couplings.

As used herein, the term “configured to” and like is at least as restrictive as the term “adapted to” and requires actual design intention to perform the specified function rather than mere physical capability of performing such a function.

As used herein, the term “resilient deformation” refers to an elastic deformation of a component or a portion of the component upon application of a force. The component, when resiliently deformed, may have a deformed state. The component may not plastically deform in the deformed state. The component may return to its undeformed state upon removal of the force. The force may be applied by another component. An extent of the elastic deformation may depend upon a magnitude of the force applied.

In general, the present disclosure provides various embodiments of a fluid nozzle and a fluid system that includes the fluid nozzle. The fluid nozzle can include a tube and a manifold disposed around tube. Typically, original equipment manufacturer (OEM) seam-sealing techniques require timeconsuming manual processes to provide seam seals that resemble original factory-applied seam seals. Such processes include using hand tools to physically create specific textures and patterns by manually changing the appearance. Further, such processes include the use of combs, modified plastic body filler spreaders, Scotch Brite™ scuff pads, or other tooling after dispensing sealer onto the surface; physically altering the dispensing through movements of the applicator, adjustment of air pressure using a trigger of a pneumatic applicator, or application of physical pressure of a manual applicator. Other techniques can also include, but are not limited to, cutting or manipulating the dispensing nozzles or selection of various sealing materials being utilized.

Conventionally, a dual cartridge system used for spraying a fluid mixture containing two fluid components includes a dual barrel cartridge unit or other source (e.g., five gallon pails, five fifty-five gallon drums) containing the two fluid component, a disposable static mixer which is connected to a fluid nozzle, and an air manifold which is connected to a supply of pressurized air. Alternatively, a single cartridge system used for spraying a single fluid component generally includes a single barrel cartridge unit or other source containing the single fluid component, a fluid nozzle connected to the single barrel cartridge unit, and an air manifold which is connected to a supply of pressurized air. Typically, for single cartridge systems, the static mixer is integral with the fluid nozzle. Hence, such fluid nozzles may not be usable with dual cartridge systems. Overall, fluid nozzles usable with dual cartridge systems are different in design from fluid nozzles usable with single cartridge systems, thereby increasing part numbers. Currently, seam sealing applications require purchasing of separate fluid nozzles based on a type of application (such as, single cartridge systems and dual cartridge systems), and may lead to confusion and incorrect ordering as well as longer wait times for completing repairs.

Therefore, there exists a need for a fluid nozzle that may be interchangeably connected to single cartridge systems as well as dual cartridge systems, thereby reducing part numbers and increasing efficiency of fluid systems that include fluid nozzles.

The present disclosure provides a fluid nozzle. The fluid nozzle includes a tube including a first tube end and a second tube end opposite to the first tube end. The tube extends along a tube axis defined between the first tube end and the second tube end. The tube includes an inlet defined at the first tube end. The tube includes an outlet defined at the second tube end. The tube further includes a fluid passageway disposed within the tube and extending from the inlet to the outlet. The tube further includes a first portion including the outlet. The first portion extends from the second tube end towards the first tube end along the tube axis. The first portion at least partially defines the fluid passageway therein. The tube further includes a second portion including the inlet. The second portion extends from the first portion to the first tube end along the tube axis. The second portion at least partially defines the fluid passageway therein. The second portion is configured to be selectively and removably connected to a first fluid source. The tube further includes a third portion extending from the first tube end towards the second tube end along the tube axis. The third portion at least partially surrounds and is connected to the second portion. The third portion includes a cylindrical section extending along a length of the third portion and at least one first coupling element disposed on the cylindrical section. The fluid nozzle further includes an adapter configured to be selectively and removably connected to the third portion of the tube when the first fluid source is disconnected from the second portion of the tube. The adapter defines an adapter channel that is in fluid communication with the fluid passageway when the adapter is connected to the third portion of the tube. The adapter is configured to be detachably connected to a second fluid source different from the first fluid source. The adapter includes a first adapter end, a second adapter end opposite to the first adapter end, an adapter axis extending between the first adapter end and the second adapter end, an inner surface, and an outer surface. The adapter is configured to at least partially receive the third portion of the tube therein through the first adapter end. The adapter includes at least one second coupling element disposed on the inner surface proximal to the first adapter end and extending angularly about the adapter axis. The at least one second coupling element is configured to at least partially receive the at least one first coupling element of the third portion therein to form a snap-fit connection between the adapter and the third portion. The tube is rotatable relative to the adapter about the tube axis upon connection with the adapter.

The fluid nozzle of the present disclosure may be used for dispensing high viscosity materials. The fluid nozzle as described herein may be interchangeably used with single cartridge systems and dual cartridge systems. More particularly, the present disclosure provides a modular fluid nozzle that may be quickly and easily connected to a mixer by a press-fit. The mixer may be in turn connected to a dual barrel cartridge unit. Alternatively, the modular fluid nozzle may be quickly and easily connected to the adapter by a snap-fit. Further, the adapter may be threadedly connected to a single barrel cartridge unit. As the modular fluid nozzle may be connected with two types of fluid systems, costs associated with handling and manufacturing of fluid nozzles with different part numbers may be eliminated. Further, the fluid nozzle may be disposable, thereby eliminating time required for cleaning and additional costs associated with cleaning solutions. Moreover, the fluid nozzle may be connectable with different designs of air manifolds and nozzle spray tips.

Further, the fluid nozzle of the present disclosure may reduce the number of applicators (and more specifically, fluid nozzles) that may be required to perform seam sealing applications to replicate OEM look and appearance, while increasing application efficiency, reducing waste, and creating a unique, no clean up solution for both single cartridge systems and dual cartridge systems.

Referring now to Figures, FIG. 1A illustrates a perspective view of a fluid nozzle 100. The fluid nozzle 100 includes a tube 102. The fluid nozzle 100 may also include a manifold 104 selectively connectable to the tube 102. In some examples, the tube 102 is a single integral component. The tube 102 includes a first tube end 106 and a second tube end 108 opposite to the first tube end 106. The tube 102 extends along a tube axis Al defined between the first tube end 106 and the second tube end 108. The tube 102 includes an inlet 110 defined at the first tube end 106. A fluid Fl (see FIG. 7) or a fluid mixture F2 (see FIG. 2) may be received within the tube 102 via the inlet 110. The term “fluid mixture” as used herein may include a combination of two different fluids that may be mixed by a mixer 204 (shown in FIG. 2) connected to the tube 102. The tube 102 further includes an outlet 112 (shown in FIG. 3) defined at the second tube end 108. The fluid Fl or the fluid mixture F2 may exit the tube 102 via the outlet 112. The tube 102 further includes a fluid passageway 114 disposed within the tube 102 and extending from the inlet 110 to the outlet 112.

The tube 102 further includes a first portion 116 including the outlet 112. The first portion 116 extends from the second tube end 108 towards the first tube end 106 along the tube axis Al. The first portion 116 at least partially defines the fluid passageway 114 therein. In some embodiments, the first portion 116 at least partially tapers in a flow direction D 1 from the first tube end 106 to the second tube end 108. Specifically, the first portion 116 may include a first tapering portion 118 having a tapering cross-section along the flow direction DI, a second uniform portion 120 having a uniform cross-section, and a third tapering portion 122 having a tapering cross-section along the flow direction DI. Each of the first tapering portion 118, the second uniform portion 120, and the third tapering portion 122 may include a circular cross-section. Alternatively, the first tapering portion 118, the second uniform portion 120, and the third tapering portion 122 may include any other cross-section, such as a square crosssection. In other examples, the first portion 116 may include a circular cross-section along a section of the first portion 116, and the first portion 116 may include a square cross-section along a remaining section of the first portion 116. Further, the first tapering portion 118 of the first portion 116 may include the outlet 112. Moreover, the second uniform portion 120 may include a continuous rib 124 extending therefrom. In other examples, the second uniform portion 120 may include more than one continuous rib (similar to the continuous rib 124), without any limitations.

The tube 102 further includes a second portion 126 including the inlet 110. The second portion 126 extends from the first portion 116 to the first tube end 106 along the tube axis Al. The second portion 126 includes wall 129 having a polygonal shape 128 along a length LI of the second portion 126. The second portion 126 at least partially defines the fluid passageway 114 therein. The second portion 126 is configured to be selectively and removably connected to a first fluid source 202 (shown in FIG. 2). In some embodiments, the polygonal shape 128 of the second portion 126 is square. In some other embodiments, the polygonal shape 128 of the second portion 126 may be rectangular, hexagonal, triangular, and so forth. The second portion 126 may be integral with the first portion 116. In some examples, a cross-sectional area of the second portion 126 may be greater than an average cross-sectional area of the first portion 116. In some embodiments, the second portion 126 may be configured to receive a section of the mixer 204 in a sealing manner. In at least one embodiment, the first portion 116 can have a different cross-sectional shape relative to the second portion 126. For example, the first portion 116 can be circular and the second portion 126 can be rectangular/square. In at least one embodiment, the wall 129 can extend from the border between the first portion 116 and the second portion 126 to the second tube end 108.

The tube 102 further includes a third portion 130 extending from the first tube end 106 towards the second tube end 108 along the tube axis Al. The third portion 130 at least partially surrounds and is connected to the second portion 126. The third portion 130 includes a cylindrical section 132 extending along a length L2 of the third portion 130 and at least one first coupling element 134 disposed on a wall of the cylindrical section 132. The at least one first coupling element 134 is disposed proximal to the second portion 126 and is distal from the first tube end 106. In the illustrated embodiment of FIG. 1A, the third portion 130 includes a single first coupling element 134. However, the third portion 130 may include multiple first coupling elements (similar to the first coupling element 134), without any limitations. In the illustrated embodiment of FIG. 1A, the at least one first coupling element 134 includes an annular rib. Specifically, the first coupling element 134 is a continuous annular rib extending about the tube axis Al . Alternatively, the at least one first coupling element 134 may include one or more tabs or projections extending from the third portion 130, one or more bosses, and the like. It should be noted that the present disclosure is not limited by a shape or a design of the first coupling element 134.

Further, in some examples, the length LI of the second portion 126 may be greater than the length L2 of the third portion 130. In some examples, the length LI of the second portion 126 may be about twice the length L2 of the third portion 130. Further, the polygonal shape 128 of the second portion 126 and the cylindrical section 132 of the third portion 130 may be co-axial with each other. In some embodiments, the third portion 130 is connected at least to each vertex 136 ofthe polygonal shape 128 of the second portion 126 along the length LI of the third portion 130. The second portion 126 may be integral with the third portion 130.

In some embodiments, the fluid nozzle 100 includes the manifold 104 configured to be detachably connected to the first portion 116 of the tube 102 by a snap-fit connection. The manifold 104 may include a first tubular portion 138 extending along a first axis A2 and configured to at least partially receive the first portion 116 of the tube 102 therein. The first tubular portion 138 may define an air outlet 140 (shown in FIG. 3) that is disposed around the outlet 112 of the tube 102. The outlet 112 may be concentrically disposed within the air outlet 140. The first tubular portion 138 may include a first section 142. The first section 142 includes a uniform cross-section. Further, the first section 142 is similar in shape to the second uniform portion 120 of the first portion 116, such that when the manifold 104 is connected to the first portion 116, the first section 142 may be disposed around the second uniform portion 120. Further, the first section 142 may include a circumferential groove 144 (shown in FIG. 5) that receives the continuous rib 124 of the second uniform portion 120 to form the snap-fit connection between the first portion 116 and the manifold 104. During an assembly of the tube 102 with the manifold 104, the continuous rib 124 may compress which may facilitate firm engagement of the manifold 104 and the tube 102 in a fluid tight assembly. In some examples, the manifold 104 and the tube 102 may be connected to one another prior to shipping to a customer, thereby facilitating use of the fluid nozzle 100 by the customer. Furthermore, the first tubular portion 138 may include a second section 146. The second section 146 includes a tapering cross-section. Further, the second section 146 is similar in shape to the first tapering portion 118 of the first portion 116, such that when the manifold 104 is connected to the first portion 116, the second section 146 is disposed around the first tapering portion 118.

The fluid nozzle 100 may further include a second tubular portion 148 extending from the first tubular portion 138 along a second axis A3 inclined to the first axis A2.

The applicator gun may include any conventional sprayable seam sealer applicator gun such as those manufactured by 3M Company (Saint Paul, MN) . The applicator gun may include rods that may push the plunger 228 of the first fluid source 202 for directing the first and second fluids F3, F4 towards the fluid nozzle 100. Further, the applicator gun may be in communication with the air source. The applicator gun may be further connected to the manifold 104 by the air supply hose. A movement of the rods and a rate of air supply into the manifold 104 may be controlled by the applicator gun. The applicator gun may have a trigger. A partial squeeze of the trigger to a first position may allow passage of air towards the manifold 104. Further, a full squeeze of the trigger to a second position activates the rods to push the first and second fluids F3, F4 towards the mixer 204. The mixer 204 may mix the first fluid F3 from the first vessel 216 and the second fluid F4 from the second vessel 218 in the mixer 204 to form the fluid mixture F2. The fluid mixture F2 may be directed into the fluid nozzle 100 via the inlet 110. Further, the fluid mixture F2 may be ejected through the outlet 112 of the fluid nozzle 100.

Referring now to FIG. 3, the fluid nozzle 100 further includes an adapter 300 configured to be selectively and removably connected to the third portion 130 of the tube 102 when the first fluid source 202 (see FIG. 2) is disconnected from the second portion 126 of the tube 102.

Further, the second fluid source 702 may include a cylindrical projection 708 that is in fluid communication with the vessel 704. The second fluid source 702 may include a plunger 710. The plunger 710 may be utilized to force the fluid Fl towards the tube 102. Alternatively, the second fluid source 702 may not include the plunger 710, and the fluid Fl may be forced towards the tube 102 by applying pressure on the vessel 704, e.g., by squeezing the vessel 704.

The adapter 300 is threadably connected to the second fluid source 702. More particularly, the internal threads 314 of the adapter 300 may engage with external threads (not shown) on the cylindrical projection 708 for connecting the adapter 300 with the second fluid source 702. It should be noted that the present disclosure is not limited by a technique of connecting the adapter 300 with the second fluid source 702.

The fluid system 700 may be coupled with an applicator gun (not shown) for accomplishing a seam sealing application. The applicator gun may include any conventional sprayable seam sealer applicator gun manufactured such as those manufactured by 3M company (Saint Paul, MN, USA). The applicator gun may include a rod that may push the plunger 710 of the first fluid source 702 for directing the fluid Fl towards the fluid nozzle 100. Further, the applicator gun may be in communication with the air source. The applicator gun may be further connected to the manifold 104 by the air supply hose. A movement of the rods and a rate of air supply into the manifold 104 may be controlled by the applicator gun. The applicator gun may have a trigger. A partial squeeze of the trigger to a first position may allow passage of air towards the manifold 104. Further, a full squeeze of the trigger to a second position activates the rod to push the fluid F 1 towards the fluid nozzle 100. The fluid F 1 may be directed into the fluid nozzle 100 via the inlet 110 and the adapter channel 302. Moreover, the fluid Fl may be ejected through the outlet 112 of the fluid nozzle 100.

FIG. 8 illustrates a flowchart for a method 800 of using the fluid nozzle 100. Referring to FIGS. 2 and 8, at step 802, the second portion 126 of the tube 102 is interchangeably connected to the mixer 204 of the first fluid source 202. At step 804, the mixer 204 is connected to the first vessel 216 of the first fluid source 202 and the second vessel 218 of the first fluid source 202. At step 806, the first fluid F3 from the first vessel 216 and the second fluid F4 from the second vessel 218 are mixed in the mixer 204 to form the fluid mixture F2. At step 808, the fluid mixture F2 is directed into the inlet 110 of the fluid nozzle 100. At step 810, the fluid mixture F2 is ejected through the outlet 112 of the fluid nozzle 100.

FIG. 9 illustrates a flowchart for a method 900 of using the fluid nozzle 100. Referring to FIGS. 7 and 9, at step 902, the third portion 10 of the tube 102 is interchangeably connected to the adapter 300 by rotating the tube 102 about the tube axis Al . At step 904, the adapter 300 is connected to the second fluid source 702.

At step 908, the fluid Fl is ejected through the outlet 112 of the fluid nozzle 100. Thus, the fluid nozzle 100 may be interchangeably connected to the first fluid source 202 containing a two fluid component as well as the second fluid source 702 containing a single fluid component, thereby reducing part numbers and increasing efficiency of the fluid systems 200, 700, respectively. Further, the fluid nozzle 100 may be interchangeably connected to the first fluid source 202, via the mixer 204, and the second fluid source 702, via the adapter 300, 600 (see FIGS. 4 and 6), without making any changes to the structure of the fluid nozzle 100. Furthermore, the present disclosure may reduce the number of applicators (and more specifically, fluid nozzles) required to perform seam sealing applications for replicating OEM look and appearance, while increasing application efficiency, reducing waste, and creating a unique, no clean up solution for the fluid systems 200, 700.

As the modular fluid nozzle 100 may be connected with two different fluid sources 202, 702, costs associated with handling and manufacturing of fluid nozzles with different part numbers may be eliminated. Further, the fluid nozzle 100 may be disposable, thereby eliminating time required for cleaning and additional costs associated with cleaning solutions. Moreover, the fluid nozzle 100 may be connectable with different designs of air manifolds and nozzle spray tips.

FIG. 10A-10B illustrate a fluid system 1000 including the manifold 104 that is attached to the tube 1002. The tube 1002 can fit over the mixer 204 in a fluid-tight manner. The tube 1002 can be similar to tube 102 except that the 1002 may lack a third portion extending from the wall of the second portion 1026.

For example, the tube 1002 can have a first tube end 1006 and a second tube end 1008 opposite from the first tube end 1006. A fluid passageway can extend from an inlet 1010 at the first tube end 1006 to an outlet at the second tube end 1008. The tube 1002 can have a first portion 1016 and a second portion 1026.

The first portion 1016 extends from the second portion 1026 towards the second tube end 1008 along the tube axis Al. In some embodiments, the first portion 1016 includes the tapering portion 1018 having a tapering cross-section along the flow direction DI. The tapering portion 1018 can lead to a continuous rib 1024 upstream from the flow direction. In at least one embodiment, the continuous rib 1024 can be arranged on the uniform portion 1020 and protrude from the uniform portion 1020 thereon. The continuous rib 1024 can be configured to catch an inner surface of the manifold 104 such that the continuous rib 1024 acts like a retention mechanism for the manifold 104. The inner surface of the manifold 104 can also include discontinuous axial ribs arranged along the axis Al such that the flow of the fluid is laminar.

The second portion 1026 can extend from the uniform portion 1020 to the first tube end 1006. In some examples, an inner cross-sectional area of the second portion 1026 may be greater than an average cross-sectional area of the first portion 1016. In some embodiments, the second portion can include a wall having a polygonal shape 1028 with vertexes 1036. The second portion 1026 can taper along the flow direction. For example, the (inner) dimension 1038 (e.g., the inner diameter from vertex to vertex in a plane perpendicular to axis Al) can be greater than the dimension 1040. It was found that the tapering along with the chamfered vertexes can result in a more secure interference fit with the mixer tube 206. The tube 1002 can have an inner surface 1042 and an outer surface 1044. In at least one embodiment, the inner surface 1042 can cause a friction or interference fit with the outer dimension of the mixer tube 206. As shown in FIG. 10C, the mixer tube 206 can have an inner surface 209 and an outer surface 207. The dimension 211 can be an outer dimension measured from one vertex on the outer surface 207 to another vertex on the opposite outer surface 207. In some embodiments, the dimension 211 can be a diameter. In at least one embodiment, the dimension 1040 can be smaller than dimension 211 such that the mixer tube 206 undergoes slight compression along the perimeter. In at least one embodiment, the dimension 1038 can be slightly larger than the dimension 211. In at least one embodiment, the outer surface 207 can be dimensioned relative to the inner surface 1042 such that there is an interference fit between the mixer tube 206 and the tube 1002. For example, 5 thousandths of an inch (0.127 mm) to 50 thousandths of an inch (1.27 mm) interference.

In at least one embodiment, the outer surface 1044 of the wall is continuous without protrusions. The cross-sectional shape of the second portion 1026 in a plane perpendicular to the axis Al is continuous along the second portion. This differs from tube 102, having athird portion 130 which has a different cross-sectional shape from the section including the second portion 1026. Such a configuration can be more streamlined and reduce material use.

FIG. 11A-1 IB illustrate a system 1100 comprising a tube 1102 that is configured to couple to the manifold 104 and the second fluid source 702 (as described in FIG. 7). The tube 1102 can differ from the tube 102 in that the tube 1002 can directly couple (e .g . , via threading 1114) to the second fluid source 702.

The tube 1102 can be a single integral component. The tube 1102 includes a first tube end 1106 and a second tube end 1108 opposite to the first tube end 1106. The tube 1102 extends along a tube axis Al defined between the first tube end 1106 and the second tube end 1108. The tube 1102 includes an inlet 1110 at the first tube end 1106. A fluid Fl may be received within the tube 1102 via the inlet 1110. The tube 1102 further includes an outlet defined at the second tube end 1108. The tube 1102 further includes a fluid passageway disposed within the tube 1102 and extending from the inlet 1110 to the outlet. The tube 1102 can also have threading 1114 integrated into the tube 1102 at the tube end 1106.

The tube 1102 can have a first portion 1116 and a second portion 1126 (proximate to the threading 1114 or other attachment mechanism). The first portion 1116 can be proximate to the tube end 1108. The first portion 1116 can include the uniform portion 1120 having a continuous rib 1124 for attachment to the manifold 104. The first portion 1116 can also include the tapering portion 1118. In at least one embodiment, the tapering portion 1118 can lead to a continuous rib 1124 upstream from the flow direction. The continuous rib 1124 can further lead to a uniform portion 1120.
