The present invention relates to an accessory for pneumatic bicycle tire valves, whereby the air pressure in a bicycle tire can be increased, decreased and checked by means of regular inflating equipment provided at gas filling stations. The invention is characterized in that the stem (2) of the body (1) is suited for the use of the nozzle of the inflator, and that the coupling aperture (4) of the coupling member (3) of the body (1) and the coupling aperture (8) of the sleeve (7) are suited for certain bicycle valve types. The body (1) contains a pin (5) provided with a spring (6) for the operations of the valves and the inflators. By employing the apparatus of the invention, the inflation of bicycle tires can now be carried out with regular inflating equipment provided at gas filling stations, according to the requirements of modern types of bicycle tires and valves. |
