<p>A carbon-dioxide pump for tires which comprises a dispensing head (T) which is provided with a nosepiece (5) for coupling to the tire valve which is connected to a threaded hole (6) for the hermetic fixing of a bottle (B) of carbon dioxide and to a sliding hole (8) for a needle-equipped pin (9) for piercing the membrane of the bottle which is rigidly coupled to a flow control element (10) of the frustum-shaped type which can be actuated manually so as to rotate in order to hermetically close the bottle (B) after piercing the membrane, a shell (27) for containing the bottle which is screwed hermetically onto the head (T) and on which a handgrip (30) is slidingly fitted with the interposition of guiding and sliding sealing elements (31,34,37) which are suitable to provide a short manual pump in which the air compressed by the movement of the handgrip (30) flows between the shell (27) and the bottle (B) and is fed to the nosepiece (5) through a nozzle (38) which is closed by a valve system (39) provided in the head (T). <IMAGE></p> |
