A device serving for sealing and inflating an inflatable object (9) provided with an inflation valve (11), for example a tire (9). The device (1) is of the kind that comprises a pressure gas source (2) and a container (3) containing a sealing agent (4). In addition, the device (1) comprises a reversing valve (5) for opening a first connection between the pressure gas source (2) and the inflation valve (11) of the object (9) in a first position and a second connection between the pressure gas source (2) and the container (3) and further between this container and the inflation valve (11) of the object (9) in a second position. In one mode of operation, the device can be used for inflating an object having gone flat to a specified pressure, and for sealing and inflating a puncture object in a second mode of operation. Thereby, the heavy and bulky spare wheel which drivers conventionally have in the car is rendered dispensable.

La présente invention concerne un appareil servant à étanchéifier et à gonfler un objet gonflable (9), tel qu'un pneu (9), qui est pourvu d'une valve de gonflage (11). Cet appareil (1) comprend une source de gaz comprimé (2) et un récipient (3) comprenant un agent d'étanchéification (4). Cet appareil (1) comprend également une soupape de commutation (5) qui, dans une première position, permet d'établir une première connexion entre la source de gaz comprimé (2) et la valve de gonflage (11) de l'objet (9) et, dans une seconde position, permet d'établir une seconde connexion entre la source de gaz comprimé (2) et le récipient (3) et entre ce récipient et la valve de gonflage (11) de l'objet (9). Cet appareil peut être utilisé d'une part afin de gonfler jusqu'à une pression prédéfinie un objet qui a perdu de l'air et d'autre part, afin d'étanchéifier et de gonfler un objet qui a perdu son étanchéité. Cette invention permet d'éviter aux automobilistes de transporter une roue de secours lourde et encombrante.
