Title
(EN) AIR CONTROL TRIGGER FOR INTEGRATED HANDHELD TEXTURE SPRAYER
(FR) GÂCHETTE DE COMMANDE D'AIR POUR PULVÉRISATEUR DE TEXTURE PORTABLE INTÉGRÉ
Abstract
(EN) A handheld sprayer comprises a housing, a turbine, a spray tip, a hopper and a trigger. An air flow passage extends through the housing. The turbine is configured to generate an airflow within the air flow passage. The spray tip is positioned to receive airflow from the air flow passage. The hopper is connected to the housing and is configured to discharge a fluid into the air flow passage. The trigger is mounted to the housing to control discharge of the hopper into the flow passage and airflow form the turbine. In different embodiments, the trigger controls airflow from the turbine to the spray tip or the hopper or both. Additionally, a method for spraying a fluid from a handheld sprayer comprises controlling airflow from a turbine and discharge from a hopper into a passage using a combined actuator.
(FR) L'invention porte sur un pulvérisateur portable, qui comprend un boîtier, une turbine, une pointe de pulvérisation, une trémie et une gâchette. Un passage d'écoulement d'air s'étend à travers le boîtier. La turbine est configurée de façon à générer un écoulement d'air à l'intérieur du passage d'écoulement d'air. La pointe de pulvérisation est positionnée de façon à recevoir un écoulement d'air à partir du passage d'écoulement d'air. La trémie est reliée au boîtier, et est configurée de façon à décharger un fluide dans le passage d'écoulement d'air. La gâchette est montée sur le boîtier de façon à commander la décharge de la trémie dans le passage d'écoulement et l'écoulement d'air à partir de la turbine. Dans différents modes de réalisation, la gâchette commande l'écoulement d'air à partir de la turbine jusqu'à la pointe de pulvérisation ou la trémie, ou les deux. L'invention porte également sur un procédé pour la pulvérisation d'un fluide à partir d'un pulvérisateur portable, lequel procédé comprend la commande d'un écoulement d'air à partir d'une turbine et sa décharge à partir d'une trémie dans un passage à l'aide d'un actionneur combiné.
