Abstract

Cette invention concerne un pulvérisateur à gâchette (10), lequel comprend un élément clapet (130) qui, lors de l'amorçage de la pompe, évacue l'air depuis une chambre de pompage (12) du pulvérisateur, vers l'intérieur d'un conteneur de liquide auquel le pulvérisateur est fixé. Dans un autre mode de réalisation, l'élément clapet (130) comprend un clapet antiretour intégré (132).
