    Abstract: An atomizing nozzle (22) for use with a rewet shower or a steam box. The nozzle has first (12) and second orifices (14) and a pressure port (16) which allows the pressure between the orifices (12, 14) to be measured. The nozzle (22) also has a pressure port (18) upstream of the two orifices (12, 14) that allows for the measuring of the regulated water pressure from an actuator (20) attached to the atomizing unit. The measured pressures can be used to determine if either orifice (12, 14, 26) is completely blocked or if one orifice is partially blocked or the other orifice is worn.

    Abstract: The actuator (2) can be used to apply fluids to the web of a papermaking machine. The actuator comprises a housing (4) having a first inlet (16) connectable to the fluid source and a second inlet (10) connectable to a pressure source. A resilient bellows structure (30) extends between the first and second inlets within the housing to define an internal region of the bellows structure in sealed communication with one of the first and second inlets and an external region of the bellows structure in sealed communication with the other inlet. A valve member (50) adapted to move with the bellows structure is provided to open and close the first inlet to vary the flow of fluid from the fluid source and maintain a pressure related to a balance of forces of the bellows structures. An outlet (58) from the housing in communication with the first inlet permits the exit of the flow of fluid to a flow controlling orifice. A pneumatic control signal provided to the second inlet controls expansion or contraction of the bellows structure.

    Abstract translation: 致动器（2）可用于将流体施加到造纸机的幅材上。 致动器包括具有可连接到流体源的第一入口（16）和可连接到压力源的第二入口（10）的壳体（4）。 弹性波纹管结构（30）在壳体内的第一和第二入口之间延伸以限定波纹管结构的内部区域，其与第一和第二入口中的一个密封连通，以及与波纹管结构密封连通的外部区域 其他入口 提供适于与波纹管结构一起移动的阀构件（50）以打开和关闭第一入口以改变来自流体源的流体流动并保持与波纹管结构的力的平衡相关的压力。 来自与第一入口连通的壳体的出口（58）允许流体流向流动控制孔口的出口。 提供给第二入口的气动控制信号控制波纹管结构的膨胀或收缩。
