The inflation system includes a pump and a dehumidifier fluidly connected between the pump and a reservoir, such as a tire.

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.

A self-inflation device for maintaining pressure in a tire, the self-inflation device includes a body having a piston compartment and an intake opening external to an inner space of the tire and a piston housed in the piston compartment and having a piston opening internal to the inner space. The piston is moved to a pulled position by centrifugal force applied by rotation of the tire to open the intake opening, and moved to a pushed position by air pressure from the inner space to block the intake opening and create a compression chamber within the piston compartment. The self-inflation device further includes a valve separating the compression chamber and the piston opening. The valve is opened when the piston is in the pushed position to allow airflow between the compression chamber and the inner space.

The inflation system includes a pump and a dehumidifier fluidly connected between the pump and a reservoir, such as a tire.

A device for transport of air in the tire P or close to it consisting of a chamber K in the shape of a hollow compressible channel, placed along at least a part of the tire perimeter, characterized by the fact that a ring OK is placed at the inner side of the chamber K with the distance of its outer side from the tire axis of rotation equal to 1 to 1.1 multiple of the distance of the bottom side of the chamber K from the axis of rotation of the tire P.

A tire inflation system and method for a tire supported by a wheel, the tire inflation system including a pump system including a pump cavity configured to fluidly connect to the tire, an actuating element configured to actuate relative the pump cavity, a drive mechanism rotatably coupled to the wheel, the drive mechanism including a motion transformer and an eccentric mass, a valve fluidly connecting the pump cavity to a fluid reservoir; and a control system configured to operate the valve.

An air maintenance system includes a rotating inner ring secured to a vehicle wheel, a stationary outer ring maintaining a constant angular position, an occlusion roller rotationally fixed to the stationary outer ring, the occlusion roller having a protruding portion centered axially at a radially outer surface of the occlusion roller with axially outer portions of the occlusion roller being radially recessed from the protruding portion and supported by bearing surfaces of the rotating inner ring, spacer rollers rotationally fixed to the stationary outer ring and rotationally supported by the bearing surfaces, and a flexible tube defining a pump cavity, the air maintenance system pumping a fluid from the ambient environment into a pneumatic tire by applying an occluding force against the flexible tube, periodically occluding portions of the pump cavity. The spacer rollers have axially outer surfaces for rotational support by bearing surfaces of the rotating inner ring and a recess centered axially at the outer surface of the spacer rollers for avoiding any contact between the spacer rollers and the flexible tube.

An air maintenance tire system component protector is provided. An air maintenance tire system includes at least one connecting tube extending between and being in fluid communication with an annular air tube and a valve housing. The protector includes a first end disposed proximate the connection of the at least one connecting tube to the annular tube, and a second end disposed proximate the valve housing. A mid-portion of the protector is disposed between the first and second ends. The protector covers an outboard surface of the at least one connecting tube and the valve housing, and includes means for engaging the at least one connecting tube to secure the position of the tube.
