Tire pressure adjusting device for e.g. tractor, has tire valve arrangement with outlet and filling valves that are passed over to their opened and closed positions when air ducts have respective pressures

摘要

The device has tires with air ducts leading from a control unit to a tire valve arrangement that has a filling valve (7) and outlet valves (8.1, 8.2). The valves are passed over to its closed position when the ducts have a low pressure. The valves (8.1, 8.2) are passed over to its opened and closed positions when ducts have high pressures. The valve (7) is then passed over to its opened position when the ducts have high pressures.
