Road vehicle provided with a tank for a compressed gas

A road vehicle (1) comprising:

• a frame (5);
• two front wheels (2) and two rear wheels (3), which are mounted on the frame (5) in a rotary manner;
• a body (6), which covers the frame (5);
• a compressor (12), which compresses air coming from the atmosphere and produces a compressed air;
• and
• at least one tank (7), which receives and stores the compressed air produced by the compressor (12) and comprises a containing chamber (9), which is delimited by a wall (10);
• wherein the compressor (12) receives a motion from a front axle or from a rear axle so as to be operated by the front wheels (2) or by the rear wheels (3);
• wherein the wall (10) of the tank (7) comprises:
• an inner panel (14), which directly delimits the containing chamber (9) and is in contact with the compressed air;
• an outer panel (15), which completely surrounds the inner panel (14) and is arranged parallel to the inner panel (14) and at a constant distance (d) from the inner panel (14);
• and a plurality of connection elements (17), which extend between the inner panel (14) and the outer panel (15) so as to physically connect the two panels (14, 15) to one another without completely filling a gap (16), which is defined between the two panels (14, 15) and is isolated from the compressed air containing chamber (9);
• wherein a cooling circuit (20) is provided, which is coupled to the tank (7) so as to cause a cooling fluid, which is separate from and independent of the air compressed by the compressor (12), to flow through the gap (16) of the tank (7);
• and
• wherein a control unit (25) is provided and is configured to drive the cooling circuit (20) so as to cause the cooling fluid to flow through the gap (16) of the tank (7) when the compressor (12) feeds the compressed air into the containing chamber (9) of the tank (7).
