用于涂料产品的静电喷涂的喷涂喷嘴以及包括这种喷涂喷嘴的用于对涂料产品进行喷涂的设备
摘要：
本发明涉及一种用于涂料产品的静电喷涂的喷涂喷嘴，喷涂喷嘴包括针(3)，针形成用于对涂料产品的喷涂进行控制的阀(63)的移动阀板并且针被定位在喷涂喷嘴的枪管的凹部(4)中。凹部(4)限定出用于对针(3)沿凹部(4)的纵向轴线(Y4)的轴向平移进行引导的引导表面(S4)。针包括前端部(3a)、后部部分(3c)以及介于前端部(3a)和后部部分(3c)之间的中心部分(3b)，前端部具有适于抵靠支座(33)以便对用于涂料产品的流动的管道(2)进行阻挡的形状，后部部分与用于对针(3)的平移进行控制的装置相互作用，而被包含在喷涂喷嘴(1)中的高电压单元能够将高电压施加到针(3)的前端部(3a)。至少一个第一突起部分(8)在凹部(4)内被设置在针的中心部分(3b)上，第一突起部分能够沿中心部分(3b)增大电气爬电距离。
摘要（英）：

The invention relates to a spray nozzle for electrostatic spraying of a coating product which includes a needle (3) which forms a mobile shutter of a valve (63) for controlling the spraying of the coating product and which is positioned in a recess (4) of a barrel of the spray nozzle. The recess (4) defines a surface (S4) for guiding the axial translation of the needle (3) along a longitudinal axis (Y4) of the recess (4). The needle includes a front end (3a) having a shape suitable for abutting against a seat (33) in order to obstruct a duct (2) for the flow of the coating product, a rear portion (3c) which interacts with means for controlling the translation of the needle (3) and a central portion (3b) comprised between the front end (3a) and the rear portion (3c), while a high-voltage unit included in the spray nozzle (1) is capable of applying a high-voltage to the front end (3a) of the needle (3). At least one first raised portion (8) is provided on the central portion (3b) of the needle, inside the recess (4), which is capable of increasing the electric creepage distance along the central portion (3b).
