Abstract

Le problème décrit par la présente invention est de fournir un élément patte d'appui anti-vibration grâce auquel il est possible de monter un dispositif sur une surface d'installation de manière appropriée même lorsque la surface d'installation servant à monter le dispositif est plus petite que la surface inférieure du dispositif. La solution selon l'invention porte sur un élément patte d'appui anti-vibration (20) qui comprend une partie patte d'appui (28) s'étendant vers le bas à partir d'une périphérie d'une surface inférieure (18) d'une pompe à air (10) et venant en butée sur une surface d'installation (BS), et une partie appui d'extension (30) s'étendant latéralement à partir de la partie patte d'appui (28) sous la pompe à air (10). La partie appui d'extension (30), lorsque la surface d'installation (BS) est sur l'intérieur de la partie patte d'appui (28), est montée sur la surface d'installation (BS) à la place de la partie patte d'appui (28), et offre un appui à la pompe à air (10) sur la surface d'installation (BS).
