The invention relates to a vacuum pump for bottles, which is particularly suitable for wine bottles which have been opened but not completely consumed. The inventive pump consists of a support (1) which can be connected to the neck (4) of the bottle and which comprises an inner constriction (2) that rests on the mouth (3) of said bottle. The aforementioned constriction forms the support base for the head (7) of a stopper (8) which penetrates the mouth (4) of the bottle and which is solidly fixed thereto. Moreover, the invention also comprises a cover (19) which can be moved axially in relation to the support (1) and which forms a variable-volume chamber (22) along with said support and the head (7) of the stopper. According to the invention, a unidirectional valve (11-14-16) is formed in the stopper (8) and a second unidirectional valve (20-21) is formed between the support (1) and the cover (19) such that, when the chamber (22) increases, air is drawn from inside the bottle and, when the chamber decreases, said air is released to the exterior
L'invention concerne une pompe à vide pour bouteilles, destinée spécialement aux bouteilles de vin entamées. Cette pompe à vide comprend un support (1) conçu pour être placé sur le goulot (4) de la bouteille, comportant un rétrécissement intérieur (2) qui vient s'appuyer sur l'embouchure (3) de la bouteille et qui constitue la surface d'appui pour la tête (7) d'un bouchon (8) destiné à être introduit et solidement fixé dans le goulot (4) de la bouteille. Cette pompe à vide comprend également un capuchon (19) pouvant se déplacer de façon axiale par rapport au support (1), formant, avec ce dernier et la tête (7) du bouchon, une chambre (22) de volume variable. La pompe à vide comprend une valve unidirectionnelle (11-14-16) située dans le bouchon (8) et une seconde valve unidirectionnelle (20-21) située entre le support (1) et le capuchon (19). Ainsi, lorsque le volume de la chambre (22) augmente, la chambre (22) aspire l'air présent à l'intérieur de la bouteille et lorsque le volume de la chambre (22) baisse, la chambre (22) expulse l'air à l'extérieur.
