Abstract

Un pistolet à pulvérisation sans air (10) comporte un ensemble soupape d'aspiration (62) à double ressort qui permet d'allonger la course de la soupape d'aspiration (62), ce qui augmente le débit du fluide à travers la soupape sans diminuer le temps de réponse de celle-ci ni les opérations d'amorçage du système. Un amortisseur contribue également à réduire la cavitation et la chute de pression dans le pistolet à peinture (10) et comprend un raccord généralement en forme de T (36) dans lequel une section (46) dudit raccord (36) est fermée et renferme un volume d'air emprisonné (52) pour amortir les forces d'accélération-décélération et les brusques pointes d'accélération transmises depuis la pompe (20) jusqu'au fluide pompé à travers le raccord (36).
