ENHANCED AIRFLOW VALVE STEM ADAPTER WITH WIDE BORE AND REPLACEABLE TIRE SEALANT FILTERRELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 677,866 filed on July 31, 2024, the entire teachings of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION
[0002] The present disclosure relates generally to a pneumatic valve design / system which has a wide bore for enhanced air flow there through. More particularly, the present disclosure relates to improvements in pneumatic valve systems which can be adapted for use with preexisting valve systems to provide enhanced airflow for use with a tire sealant filter. The adaptable wide bore valve stem may be used with tube and tubeless tires.BACKGROUND OF THE INVENTION
[0003] Various pneumatic values have been long used to regulate pressurized air in tires, tubes, and other pressurized structures. Pneumatic values known in the art include the Schrader (also referred to as an American valve), Presta (also referred to as a French or Sclaverland valve), and Dunlop (also referred to as a Woods, English, or Blitz valve) valves, among others. These valves have been widely adopted in various industries notably tires, including, tube and tubeless tires in bicycle and automotive applications.
[0004] These values are used with standard sized stems leading to the tire or pressurized volume being inflated. The standardized size stems offer advantage in compatibility with different types of valves but due to their narrow bore restrict airflow during inflation. This can lead to increased inflation times which can be particularly detrimental in race scenarios, e.g., bicycle racing, and is exacerbated when inflating. With the rise of electric bicycles, thicker tires are becoming more prevalent which require more air, and consequently more time, to inflate.
[0005] Furthermore in the context of tubeless tires, an initial threshold pressure is require to adhere the tire to the rim during inflation. Until this threshold pressure is reached the tire creates an imperfect seal allowing air to escape - again increasing inflation time. If a user is unable to inflate their tubeless tire fast enough, due to physical limitations or fatigue, the tire may not seal to the rim preventing the user from being able to inflate the tire at all.
[0006] Additionally, tubeless tires often utilize tire sealant to help create a seal between the tubeless tire and the rim. This sealant may flow back up the valve stem and become lodged in the valve reducing the air flow through the valve or even sealing the valve shut. To counter act this a filter may be used to catch tire sealant before it becomes lodged in the valve; however, such filters add a further restriction to the airflow to the tire and may become clogged or fouled with the sealant over time.
[0007] Accordingly, there exists a need for an improved pneumatic valves and pneumatic valve adapters which enhance airflow and include the features described herein.SUMMARY OF THE INVENTION

[0061] Corresponding reference characters indicate corresponding parts throughout the several views of the drawings. Although specific features of various examples may be shown in some drawings and not in others, this is for convenience only. Any feature of any drawing may be referenced or claimed in combination with any feature of any other drawing.DETAILED DESCRIPTION
[0062] The following detailed description and examples set forth preferred materials, components, and procedures used in accordance with the present disclosure. This description and these examples, however, are provided by way of illustration only, and nothing therein shall be deemed to be a limitation upon the overall scope of the present disclosure, like .
[0063] The present disclosure provides exemplary embodiments of a pneumatic valve system including a valve, a wide bore adapter and valve stem. The described valve system serves as an improved alternative to conventional pneumatic valves known and used in the artfor both tube and tubeless tires. The disclosed valve system and adapter are designed to have backwards compatibility with existing valves and pump heads. Accordingly, it is appreciated that variations in the size, scale, or dimensions of the disclosed valve may vary to comport with known pneumatic valves and pump heads, e.g., Schrader, Presta, or Dunlop valves and pump heads, are contemplated herein. Accordingly, it is expressly within the scope of the present disclosure that the embodiments and teachings described herein are applicable to and may be adapted for use as or with any known pneumatic valves and pump heads, including but not limited to Schrader, Presta, and Dunlop valves and pump heads. Any dimensions provided in the figures or the specification are for illustration purposes, are non-limiting, and are to be construed as exemplary embodiments.
[0064] Additionally, the wide bore adapter design disclosed herein provides for enhanced airflow which facilitates use with a tire sealant filter or tubeless tires. The wide bore allows for enhanced airflow which may blow / flow sealant which has traveled up the valve stem and is caught in the filter back into the tire. Further, the increased airflow facilitates the tire to become locked into place in the rim of a tubeless tire creating an air tight seal during an installation or repair process. It should be appreciated that if sufficient air pressure and volume in the tire is not achieved in the initial inflation stage, a seal between the tire and the rim may not be formed, as a result either the tire will not hold pressure or the air will gradually leak out of the tire. Therefore, the present disclosure provides significant improvements in functionality over known valves.
[0065] The following discussion of FIGS. 1A-1F and 2A-2E relate to a pneumatic valve which may be used with a wide bore enhanced airflow adapter discussed herein.
[0066] Referring now to FIGS. 1A-1F, shown is a pneumatic valve 100 according to an embodiment. The valve 100 may have a generally cylindrical and hollow body 101 with varying diameter geometry along the length of the body 101 having an inlet or first end 126 and an outlet or second end 130. The first end 126 may receive at least a portion of a pump head and the second end 130 may be disposed in a valve stem or adapter for discharging air into an inflatable structure. In an embodiment one or both of the first end 126 and the second end 130 may be beveled, chamfered, or otherwise angled. The body 101 may include a groove 102, knurling 104, flat grip 106, and threading 108 on the body 101 and a valve gasket 110 disposed around the body 101 near or adjacent to the second end 130. The groove102 may be a concave grove about the circumference of the body 101 and may be adapted to receive an O-ring. The knurling 104 and flat grip 106 may provide the user superior handling of the valve when attaching / securing the pump head or the valve stem.
[0067] The valve 100 may also have an passage 124 disposed though the body 101 between the first end 126 and the second end 130. The passage 124 may include an outlet portion 128 near or adjacent to the second end 130. The outlet portion 128 may have a smaller diameter than the passage 124 defining a first shoulder 120 where the passage 124 and outlet portion 128 meet. The passage 124 may also include an O-ring 132 therein, whereby the passage 124 has a grove in the inner diameter of the passage 124 which receives at least a part of the O-ring 132.
[0068] A plug 112 may be disposed through the passage 124 and portions of the plug 112 may extend out of the body 101 through the first end 126 and the second end 130. The plug 112 may have a head 115 having a generally T-shape defining a second shoulder 122. As illustrated in FIGS. IE and 1G, the length of the head 115 may be generally equal to the diameter of the passage 124 with spaces 134 on either side of the head 115 allowing for air to pass into the passage 124. The plug 112 may have a pin 116 extending out from the head 115. In an embodiment the head 115 is located below the O-ring 132 opposite the first end 126 and the pin 116 extends though the O-ring 132 and is partially exposed out of the first end 126. The plug 112 may include a plug gasket 114 disposed around a portion or end of the plug 112 opposite the head 115 and the pin 116. The plug gasket 114 may be sized to, in combination with the plug 112, have a diameter greater than the diameter of the outlet portion 128.
[0069] The passage 124 may also house a constant force spring 118 therein. In an embodiment, the spring 118 is a compression spring. Opposing ends of the spring 118 may rest on the shoulders 120, 122 and apply a biasing force on the plug 112 via the second should 122. The spring 118 may bias the valve 100 and plug 112 into a first position (also referred to as a closed or disengaged position). In an embodiment it may be desirable to use a spring 118 with similar load values to known valves when in the first position and the second position (also referred to as an open or engaged position). This may in turn provide a user a similar feel when engaging and disengaging the pump and provide greater backwards compatibility with preexisting systems.
[0070] In an exemplary non-limiting embodiment the spring 118 exerts a load of 0.27 lbs (1.2 Ns) when in the first position and a load of 0.53 lbs (2.4 Ns) when in the second position. In a further exemplary embodiment the spring 118 exerts a load of 0.28 lbs (1.2 Ns) when in the first position and a load of 0.51 lbs (2.3 Ns) when in the second position. In yet a further exemplary embodiment the spring 118 exerts a load of between 0.22 and 0.32 lbs when in the first position and a load of 0.48 and 0.58 lbs when in the second position.
[0071] In the exemplary non-limiting embodiment illustrated in FIG. 1C, shown is the valve 100 in the closed or first position. The spring 118 biases the plug 112 toward the first end 126 whereby the plug gasket 114 is wedged into the second end 130 and outlet portion 128 creating an air tight seal and the pin 116 extends through the O-ring 132 and partially out of the first end 126. The outlet portion 128 is sized to prevent the plug gasket 114 from passing through the outlet portion 128 even when then plug gasket 114 is compressed due to the force of the spring 118 and pressure forces. Further, the second end 130 is angled and sized to receive the plug gasket 114, thereby creating a tighter seal as the plug gasket 114 experiences higher compression forces.
[0072] As further illustrated in FIG. ID, in an exemplary embodiment, the valve 100 in shown in the open or second position. A force compresses the spring 118 and moves the plug 112 through the second end 130 whereby the end of the pin 116 is below the first end 126 and fully inside the passage 124. The plug gasket 114 is disengaged from the outlet portion 128 and the second end 130 thereby opening the valve 100 to allow air to pass through the first end 126, the spaces 134, the passage 124, the outlet portion 128 and the second end 130.
[0073] FIGS. 2A-2E illustrate a valve 200 according to an alternate embodiment. Valve 200 may be substantially similar to or the same as valve 100, except that O-ring 132 may be positioned closer to the first end 126 than groove 102 such that the O-right 132 and groove 102 are swapped positional on valve 200 compared to valve 100.
[0074] Referring now to FIGS. 3A-3B shown is a cross section of pneumatic valve system with a wide bore adapter 300 having a filter, dual sealing, and an internal stem connection according to some embodiments of the present disclosure. The wide bore adapter 300 may have a generally cylindrical and hollow body including an inner body 301 and anouter body 303. In some embodiments, the inner body 301 and the outer body 303 are coupled by a press fit seal. In other embodiments, the inner body 301 slots into the outer body 303 via respective external threads 305 (shown in FIG. 6) on the inner body 301 and internal threads 307 (shown in FIG. 6) on the outer body 303. An O-ring 315 is positioned in a circumferential slot 317 in the inner body 301 forming an air tight seal between the inner body 301 and the outer body 303.
[0075] In some embodiments, a filter 309 may be positioned between a bottom end 311 of the inner body 301 and an internal shoulder of 313 of the outer body 303. The filter 309 may be made of silicon and have a plurality of holes to allow air to pass through, the plurality of holes in the filter may be sized and dimension as to reduce, prevent, or substantially prevent tire sealant from passing through, for example via surface tension of the sealant. In some embodiments, the silicon filter 309 may be replaced with steel wool or another porous material which is capable of allow air to pass through while being able to capture tire sealant. In some embodiments, the seal between the inner body 301, the filter 309, and the outer body 303 is air tight and may replace or supplement the seal formed by the O-ring 315. In some embodiments, the filter 309 has an outer dimeter of 7 mm and is 1 mm thick.
[0076] The inner body 301 includes a valve extension 319 opposite the bottom end 311 for receiving a valve 100. It is appreciated that while discussion of specific embodiments make reference to use with the valve 100, the valve 200 may be used interchangeably with the valve 100. The valve extension 319 may have internal threading 321 corresponding to threads 108 on the valve 100. When the valve 100 is slotted into the valve extension 319 the respective threads 108, 321 cooperate to wedge the valve gasket 110 into an internal tapered portion 323 of the valve extension 319 to create an air tight seal between the valve 100 and the wide bore adapter 300.
[0077] The outer body 303 includes a stem extension 325 which extends away from the inner body 301 for connecting the wide bore adapter 300 to a valve stem 350. It is appreciated that while discussion of specific embodiments make reference to and depict a tubeless tire stem, the wide bore adapter 300 may be used with a tube tire stem. The stem extension 325 may have external threading 327 corresponding to threads 351 on the valve stem 350. When the outer body 303 and the stem extension 325 are slotted into the valvestem 350 the respective threads 327, 351 cooperate to wedge a stem gasket 329 into an internal tapered portion 353 of the valve stem 350 to create an air tight seal between the wide bore adapter 300 and the valve stem 350.
[0078] The inner body 301 has an internal chamber 331 having a diameter d defining the wide bore passage for airflow there through. The inner body 301 may have a diametric clearance 333 relative to the plug 112 and the plug gasket 114. The diametric clearance 333 being greater than a standard pneumatic valve to provide enhance airflow there through relative to a standard pneumatic valve. In some embodiments, the diametric clearance 333 is 1.2 mm greater than a standard pneumatic valve. In some embodiments, the diametric clearance 333 is .45 mm greater than a standard pneumatic valve. The internal chamber 331 may be sized and dimension such that there is sufficient valve stroke clearance 335 and clearance 337 to prevent contact between an end of the plug 112 and the filter 309. In this way the plug 112 cannot be over depressed to cause contact with the filter 309. In some embodiments, the valve stroke clearance 335 may be 3.5 mm and the clearance 337 may be .5 mm; however, it is appreciated that the specific valve stroke clearance 335 and clearance 337 of a particular wide bore adapter 300 will depend on the valve being used. The wide bore adapter 300 has an outer diameter D and a height H. The height H and outer dimeter D will vary based on the wall thickness of the inner body 301 and the outer body 303 as well as the desired diametric clearance 333, valve stroke clearance 335, and clearance 337. In some embodiments, the outer diameter D may be 9.5 mm and the height H may be 10.12 mm.
[0079] Referring now to FIGS. 4A-4C, shown are front, side, and perspective views of a wide bore adapter 300 according to some embodiments of the present disclosure. In some embodiments, the outer body 303 may have knurling 339 and the valve extension 319 may have a flat grip 341. The knurling 339 and flat grip 341 may provide a user enhanced grip when tightening the various components of the pneumatic valve system together, including the inner body 301, the outer body 303, the valve 100, 200, and the valve stem 350.
[0080] Referring now to FIGS. 5A-5C, shown are perspective, front, and side views of a pneumatic valve system with a wide bore adapter 300 according to some embodiments of the present disclosure. In some embodiments, the flat grip 341 on the valve extension 319 and the flat grip 106 on the valve 100 may be aligned when the valve 100 is secured to the wide bore adapter 300. In this way the user is provided a visual cue that the valve 100 is secured.
[0081] Referring now to FIG. 6, shown is a cross section view of a wide bore adapter 600 with thinned walls, a filter, dual sealing, and an internal stem connection according to some embodiments of the present disclosure. The wide bore adapter 600 may be similar to or the same as the wide bore adapter 300, except that the walls of the inner body 301 and the outer body 303 are thinner allowing for the profile or diameter of the wide bore adapter 600 to more closely resemble a standard pneumatic valve.
