Abstract

L'invention porte sur un pulvérisateur de liquides (10) avec une pompe actionnée par une gâchette, lequel pulvérisateur comprend un corps (11) qui peut être attaché à l'embouchure d'un récipient et une buse (16) de distribution du liquide, une chambre de pompage (22) étant formée dans le corps (11), en communication avec l'intérieur du récipient et avec la buse de distribution (16), par l'intermédiaire d'une soupape unidirectionnelle d'aspiration et de distribution (30), un système de précompression étant disposé dans le conduit de sortie (29) pour le liquide, comprenant un piston (41) poussé avec une force constante par un ressort (42) contre ladite buse de distribution (16) de façon à augmenter la pression du liquide dans ledit conduit de sortie (29) pendant le pompage, et, par conséquent, la vitesse ou l'accélération du liquide en sortie à partir de la buse (16).
