NIPPLE AUTOMOTIVE TIRE (TIRE VALVE) WITH PNEUMO-HYDRAULIC AUTOMATIC AUTONOMOUS PUMPING Russian patent published in 2017 - IPC B60C23/12 

FIELD: automotive engineering.

SUBSTANCE: nipple of the car tire has a pumping chamber, bounded by the inner and outer walls of the elastic material, the space between them is filled with liquid or similar material. The nipple works by transferring the pressure force from the outer wall to the inner wall as the pressure in the tire increases, which leads to an increase in the pressure in the pumping chamber and the supply of additional air to the tire. As the area of the outer and inner walls is different, and the liquid is not compressible, the transfer of the pressure force from the outer wall to the inner wall occurs with increasing.

EFFECT: ensuring the possibility of swapping the tires of the car due to short-term pressure changes caused by the passage of various irregularities.
