(FR) PISTOLET PULVÉRISATEUR DE PEINTURE
Abstract
(DE)
Farbsprühpistole, umfassend einen rohrformigen Grundkörper (22), einen an dem Grundkörper (22) vorgesehenen Griff (23) mit einem betätigbaren Abzug (6), wobei der Grundkörper (22) an einer ersten Stirnseite (25) eine Sprühöffnung (46) aufweist, ein in dem Grundkörper (22) angeordnetes Düsenteil (4) und eine in dem Düsenteil (4) verschiebbare Düsennadel (5), wobei eine Betätigung des Abzugs (6) eine Verschiebung der Düsennadel (5) in dem Düsenteil (4) bewirkt, sowie eine Lufteinlassöffnung (37) und ein mit einem Elektromotor (28) angetriebenes Gebläse (36) zur Erzeugung einer Luftströmung von der Lufteinlassöffnung (37) zu der Sprühöffnung (46), dadurch gekennzeichnet, dass der Elektromotor (28) und das Gebläse (36) in dem Grundkörper (22) angeordnet sind und die Lufteinlassöffnung (37) an einer der ersten Stirnseite (25) gegenüberliegenden Stirnseite (48) des Grundkörpers (22) angeordnet ist.
(EN)
The invention relates to a paint spray gun, comprising a tubular main body (22) and a handle (23) which is provided on the main body (22) and has an actuatable trigger (6), wherein the main body (22) has a spray opening (46) on a first end face (25). The paint spray gun comprises a nozzle part (4) arranged in the main body (22) and a nozzle valve (5) which can be moved in the nozzle part (4), wherein actuation of the trigger (6) causes the nozzle valve (5) to move in the nozzle part (4). The paint spray gun also comprises an air inlet opening (37) and a fan (36) which is driven by an electric motor (28) for producing an air flow from the air inlet opening (37) to the spray opening (46). The invention is characterised in that the electric motor (28) and the fan (36) are arranged in the main body (22) and the air inlet opening (37) is arranged on an end face (48) of the main body (22) opposite the first end face (25).
(FR)
Pistolet pulvérisateur de peinture comprenant un corps de base (22) tubulaire, une poignée (23) prévue sur le corps de base (22) et dotée d’une gâchette (6) actionnable, le corps de base (22) présentant sur une première face frontale (25) un orifice de pulvérisation (46), un élément buse (4) logé dans le corps de base (22) et une aiguille de buse (5) insérable dans l’élément buse (4), un actionnement de la gâchette (6) provoquant un déplacement de l’aiguille de buse (5) dans l’élément buse (4), ainsi qu’un orifice d’entrée d’air (37) et une soufflante (36) entraînée par un moteur électrique (28) et destinée à générer un flux d’air entre l’orifice d’entrée d’air (37) et l’orifice de pulvérisation (46), caractérisé en ce que le moteur électrique (28) et la soufflante (36) sont logés dans le corps de base (22) et l’orifice d’entrée d’air (37) est disposé sur une face frontale (48) du corps de base (22) opposée à la première face frontale (25).
