Abstract

Cette invention concerne un pulvérisateur (20) à pompe permettant de vaporiser des liquides tel que des insecticides ou des herbicides. Ce pulvérisateur (20) comprend un conteneur d'alimentation (22) contenant le fluide à vaporiser, une pompe (42) à piston actionnée manuellement, un récipient sous pression ou accumulateur (34), ainsi qu'un clapet à commande manuelle (104) permettant de régler le débit du fluide vaporisé à l'aide d'une lance (106) de pulvérisation. L'accumulateur (34) comprend une vessie élastomère (76) dans laquelle va s'accumuler un fluide provenant de la pompe, laquelle vessie va envoyer le fluide jusqu'à la lance de pulvérisation (106) à la pression voulue. Afin d'obtenir un pulvérisateur (20) à pompe qui puisse fournir un fluide à une pression relativement constante depuis une source de liquide d'un conteneur traditionnel, la pompe (42) et la vessie élastomère (76) sont conçues de manière à pouvoir être introduites par les ouvertures de remplissage des conteneurs (22), et à pouvoir être fixées à l'intérieur de ces derniers lors du fonctionnement du pulvérisateur (20).
