摘要： An OFF/OFF valve including a fluid passage formed in the valve body, and having a valve seat, a smaller diameter portion extending from the valve seat on a downstream side of the valve seat, and a larger diameter portion extending from the smaller diameter portion on a downstream side of the smaller diameter portion. A valve element is disposed so as to be movable between a position adjacent the valve seat and a position within the larger diameter portion. The valve element is driven by a valve element driving assembly. When the valve is closed, the valve element moves toward the valve seat. When the valve element moves within the smaller diameter portion, the fluid which has passed through the valve element is drawn back due to the pumping effect of the valve element before the valve element finally reaches the valve seat and the valve is completely closed.
摘要翻译：一种关闭/关闭阀，包括形成在阀体中的流体通道，并且具有阀座，在阀座的下游侧从阀座延伸的较小直径部分和从较小直径部分延伸的较大直径部分在较小直径部分的下游侧。阀元件设置成能够在邻近阀座的位置和较大直径部分之间的位置之间移动。阀元件由阀元件驱动组件驱动。当阀关闭时，阀元件向阀座移动。当阀元件在较小直径部分内移动时，在阀元件最终到达阀座并且阀完全关闭之前，由于阀元件的泵送效应，已经通过阀元件的流体被拉回。

摘要： A coating nozzle for a high-viscosity paint is equipped with an introduction passage, an inner space, and a nozzle slit, which communicate with one another, and sprays a coating body with the high-viscosity paint from the nozzle slit in a radial direction. The nozzle slit is constructed in a sectional shape having a predetermined angle in a plan view. When the nozzle slit is regarded as having the sectional shape, an arc of the sectional shaped nozzle slit serves as a nozzle slit outlet. The nozzle slit outlet has a nozzle slit outlet width equal to or larger than 35 mm and a flattening equal to or smaller than 0.01 where a slit height represents a clearance of the nozzle slit outlet, the nozzle slit outlet width represents a chord of the arc, and the flattening represents a ratio of the slit height to the nozzle slit outlet width.
摘要翻译：用于高粘度涂料的涂布喷嘴配备有彼此连通的引入通道，内部空间和喷嘴狭缝，并且从喷嘴狭缝沿径向喷射具有高粘度涂料的涂层体。喷嘴狭缝在平面图中被构造成具有预定角度的截面形状。当喷嘴狭缝被认为具有截面形状时，截面形状的喷嘴狭缝的弧线用作喷嘴狭缝出口。喷嘴狭缝出口具有等于或大于35mm的喷嘴狭缝出口宽度和等于或小于0.01的平坦度，其中狭缝高度表示喷嘴狭缝出口的间隙，喷嘴狭缝出口宽度表示弧的弦平坦化表示狭缝高度与喷嘴狭缝出口宽度的比率。

摘要： A rotary atomizing electrostatic coating apparatus includes air feed passages connected to an air bearing, a turbine, and a shaping air cap, respectively. In any one of air feed passages, a divergence portion for causing a portion of air flowing in the one air feed passage to diverge from the one air feed passage is formed so that a diverging air flows into an interior of the drive shaft. As a result, it is not necessary to provide an additional, air feed passage and an air source therefor for preventing paint from entering a bearing clearance between the drive shaft and the air motor. As a result, a size of the apparatus will not be large and a cost of the apparatus will not substantially increase.
摘要翻译：旋转雾化静电涂布装置包括分别连接到空气轴承，涡轮机和成形气帽的空气供给通道。在空气供给通道中的任何一个中，形成一个用于使一个空气供给通道中流动的空气的一部分与一个空气供给通道分离的发散部分，使得分流的空气流入驱动轴的内部。结果，不需要提供另外的空气供给通道和空气源，以防止涂料进入驱动轴和气动马达之间的轴承间隙。结果，设备的尺寸将不会很大，并且设备的成本将不会显着增加。

摘要： A rotary atomizing electrostatic coating apparatus includes a plurality of paint nozzles and a solvent nozzle. Each paint nozzle communicates uniquely with a respective paint source separate by respective paint passages which are pathwise separate from each other. In each paint passage, a respective paint valve is installed. When changing a painting color according to the present invention, the paint filling the operating paint nozzle and the paint passage connected thereto is not washed out by a washing solvent, so that the amount of paint wasted when changing the painting color is decreased to substantially zero and the working time period for changing the painting color is also shortened. A corresponding method of use of such an apparatus is also disclosed which reduces the amount of paint wasted and the amount of solvent used during a step of switching from a first paint to a second paint.
摘要翻译：旋转雾化静电涂布装置包括多个涂料喷嘴和溶剂喷嘴。每个涂料喷嘴与相应的油漆通道独立地相互连通，油漆通道彼此分开地分开。在每个涂料通道中，安装相应的涂料阀。当根据本发明改变油漆颜色时，填充操作油漆喷嘴和连接到其上的油漆通道的油漆不被洗涤溶剂洗掉，使得当改变涂漆颜色时浪费的油漆量减少到基本上为零并且改变绘画颜色的工作时间段也缩短了。还公开了使用这种装置的相应方法，其减少了在从第一涂料转变为第二涂料的步骤期间所浪费的涂料的量和所用溶剂的量。
