    • An intake device has a passage member defining a fluid passage, a housing, a valve member and a shaft member. The housing is disposed in the passage member such that a passage of the housing is in communication with the fluid passage of the passage member. The valve member is disposed in the housing to open and close the passage of the housing. The valve member has a tubular portion and a wing portion extending from the tubular portion. The shaft member is disposed to pass through the passage member and the tubular portion of the valve member in a direction perpendicular to an axis of the fluid passage of the passage member. The shaft member is disposed such that a portion of the shaft member located inside of the tubular portion retains an elastic force against an inner wall of the tubular portion.
    • 进气装置具有限定流体通道,壳体,阀构件和轴构件的通道构件。 壳体设置在通道构件中,使得壳体的通道与通道构件的流体通道连通。 阀构件设置在壳体中以打开和关闭壳体的通道。 阀构件具有管状部分和从管状部分延伸的翼部分。 轴构件设置成沿着与通道构件的流体通道的轴线垂直的方向穿过通道构件和阀构件的管状部分。 轴构件设置成使得位于管状部分内部的轴构件的一部分保持抵抗管状部分的内壁的弹力。

    • A servo valve is connected to a hydraulic cylinder for driving a movable body for shifting. A control signal is applied from a controller to the servo motor for controlling speed of the movable body in an injection molding machine. Control is performed in such a manner that open-loop control of a speed is performed by applying a control signal on the basis of a speed command value to the servo motor in a shifting zone of the movable body including an acceleration region. Closed-loop control is performed by applying a control signal (derived on the basis of a deviation between a speed detection valve and speed command value), to the servo valve in a shifting zone of the movable body including a decelerating region. By such a control method, in which the shifting zone including the accelerating region and the shifting zone including the decelerating region are separated, stability of control, necessary response characteristics, and precision can be maintained in a shifting range.
    • 伺服阀连接到用于驱动移动体的液压缸。 控制信号从控制器施加到伺服电动机,用于控制注射成型机中的可移动体的速度。 以通过在包括加速区域的可移动体的移动区域中,基于速度指令值向伺服电动机施加控制信号来执行速度的开环控制的控制。 通过在包括减速区域的可移动体的换档区域中将伺服阀施加控制信号(基于速度检测阀和速度指令值之间的偏差导出)来执行闭环控制。 通过这样的控制方法,其中包括加速区域和包括减速区域的换档区域的换档区域分离,可以在变速范围内保持控制的稳定性,必要的响应特性和精度。
