Publication number: 20230226861Abstract: A chamber is provided that works as a peristaltic pump for the pressure correction in the tire, which is a part of the tire or of an ancillary structure placed between the rim and the tire bead and is connected with the tire internal space at one end and with the external environment at the other end. The chamber is in the shape of a curved hollow channel, where at least one enclosing wall is at least partially formed by at least a pair of surfaces coplanar with the longitudinal direction of the chamber. When the tire is mounted on the rim, the pair of surfaces are pressed together thus hermetically closing the chamber. When the chamber is closed during rotation of the wheel, the surfaces can slightly slide on one another taking internal wall tensions onto themselves thus decreasing the possibility of wall damage through ripping.Type: ApplicationFiled: March 23, 2023Publication date: July 20, 2023Applicant: CODA INNOVATIONS S.R.O.Inventor: Frantisek HRABAL

Publication number: 20230219383Abstract: A device for adjustment of pressure in tires includes a chamber with shape memory and a valve. The valve is a three-way valve with inputs interconnected with the external environment and the tire internal space, where one input is fitted with a valve, the next input is connected to one end of the chamber with shape memory, and the last input is interconnected with the closure element. The device for adjustment of pressure in tires includes the chamber with shape memory interconnected with the external environment through an input and with the tire chamber through an output and fitted with at least one valve. The length of the chamber in the direction of tire rotation equals 0.001 to 0.5 of the tire perimeter, where the volume of the chamber before deformation to volume of the chamber during deformation ratio is the same or higher then the desired tire pressure to pressure of the external environment ratio.Type: ApplicationFiled: March 8, 2023Publication date: July 13, 2023Applicant: CODA INNOVATIONS S.R.O.Inventor: Frantisek HRABAL

Publication number: 20230173855Abstract: A device for maintaining and changing the pressure in a is provided whereby the inner pressure space of the tire is connected through a pump to a pressure accumulator which, at its input and/or output into the inner pressure space of the tire, is fitted with at least one pressure control element. The pump can be a peristaltic pump in the shape of a deformable hose placed on the perimeter of the tire, fitted with an air inlet and an air outlet, while the air inlet and the air outlet are positioned on the perimeter of the tire distant from each other by a preset length, dependent on the deformation of the tire.Type: ApplicationFiled: January 28, 2023Publication date: June 8, 2023Applicant: CODA Innovations s.r.o.Inventor: Frantisek HRABAL

Publication number: 20220161611Abstract: All tire systems, including tire systems that include self-inflating devices, need to have the ability to regularly and reliably monitor and report vehicle and tire conditions for safety reasons. For a self-inflating tire, this can be accomplished by monitoring the operation of the self-inflation system, and assessing if it is consistent with a tire in good condition.Type: ApplicationFiled: February 7, 2022Publication date: May 26, 2022Applicant: CODA Innovations s.r.o.Inventor: Frantisek HRABAL
