FIELD: mechanic.
SUBSTANCE: wheel with regulated pressure is proposed, containing rim connected with a chamber, and capable of being filled with fluid up to the first pressure, tyre installed on the rim, having an internal volume pumped up to the working pressure under the reference temperature. The working pressure is lower than the first pressure. As a minimum, there is one valve unit, designed with the possibility of establishing communication between the chamber, the internal volume of the tyre, and the atmosphere. The valve unit contains setting valve, an outlet valve, and equalising valve, functionally connected with each other. The setting valve is designed so that it can control the communication between the chamber and the internal volume of the tyre. The outlet valve is connected with the atmosphere, the internal volume, the setting valve, and the equalising valve. The equalising valve is connected with the outlet valve and the setting valve. The setting valve has an internal chamber connected with the outlet valve and with the equalising valve so that the setting valve acts from the outlet valve and the equalising valve due to the changing of pressure in the internal chamber in response to the changing of the internal pressure in the tyre.
EFFECT: optimal pressure in tyre is maintained, depending on ambient air temperature.
