Abstract
A control circuit for controlling the pressure of a wheel enclosing a first volume and a second volume includes a controlled pressure line, a first line, connectable to the controlled pressure line and connected to the first volume for introducing air inside the first volume, and a second line, connectable to the controlled pressure line and connected to the second volume for introducing air inside the second volume. The control circuit further includes a first spool valve, which is a three way-two positions valve, having a first position in which the controlled pressure line is connected to the first line, and a second position, in which the controlled pressure line is connected to the second line. The first spool valve switches from the first position to the second position if the pressure in the first volume exceeds a predetermined pressure.
