    Abstract: 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.

    Abstract: A movable tire inflation apparatus includes an inflation device and a fixing structure. The inflation device includes a casing defining an accommodation room. The accommodation room is equipped with an inflation component, and an electrical control module which is connected electronically to the inflation component. At least one magnetic positioning member is disposed at one side of the casing. The fixing structure is disposed at an outer side of the inflation device in such a manner to fix the inflation device on an outer side of a wheel and the magnetic positioning member is magnetically positioned at one side of the wheel. In this way, the movable tire inflation apparatus is fixed on the outer side of the wheel and connected to the wheel by the inflation device, to inflate a tire as the wheel is moving, providing advantages in easy carriage, repair convenience and safety improvement.

    Abstract: A tire assembly includes a reservoir, a tire, and a pressure module. The pressure module includes a first valve, a second valve, and a control unit. The first valve selectively directs air from the reservoir to the interior cavity. The second valve directs air from the interior cavity of the tire to the atmosphere. The control unit is configured to selectively send a first control signal to the first valve such that the first valve cycles from a first position, at which air is prevented from flowing from the reservoir to the interior cavity, to a second position, at which air is allowed to flow from the reservoir to the interior cavity of the tire. The control unit is configured to selectively send another first control signal to the first valve such that the first valve cycles from the second position to the first position.
