The invention relates to a compressor assembly for supplying pressure medium to a tire cavity of a vehicle wheel that can be mounted on a wheel hub which can be mounted on a wheel carrier so as to be rotatable about an axis of rotation. The compressor assembly includes a wheel mount-side transmission component including a cylindrical cam.

A compressor assembly for supplying pressure medium to a tire cavity of a vehicle wheel that can be mounted on a wheel hub which is mounted on a wheel carrier so as to be rotatable about an axis of rotation. A transmission, preferably a cam mechanism, is equipped, through a cooperation of a wheel mount-side transmission part with a hub-side transmission part, to convert a rotary movement between the wheel mount side and the wheel hub side into an oscillating translatory movement of the compressor component, with the translatory movement of the compressor component extending at least partially, preferably entirely, in a radial direction that is oriented orthogonally to the axis of rotation.

A control valve suitable for use with a tire and pump assembly is described that controls the flow of air from the pump into the tire. The control valve includes an optional bi-directional feature. The pathways alternatively operate to deliver ambient non-pressurized air to the air pumping tube in response to directional tire rotation against a ground surface.

Provided is a tire assembly includes a tire, a power generating body disposed inside the tire, and an electronic device that receives supply of power that is output from the power generating body. The power generating body includes a first insulating film, a second insulating film, a first electrode, and a second electrode. The first insulating film has a first surface. The second insulating film has a second surface. The first and second electrodes have conductivity. The power generating body is configured such that a true area of contact between the first surface and the second surface changes according to deformation of the tire.

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.

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 connecting member and method of forming the connecting member in an air maintenance tire is provided. The method includes providing a tire having a sidewall formed with an annular groove. The groove receives an annular air tube having a first end with a first fitting and a second end with a second fitting. A recess is formed in the tire sidewall along the annular groove at a location where the first end of the annular air tube is adjacent the second end of the annular air tube. A mold formed with a cavity is provided and the fittings are removably secured in the cavity. The mold is positioned on a surface of the tire sidewall and an elastomer or a polymer is introduced into the mold cavity. The mold is heated to form the connecting member on the tire sidewall.
