    • An apparatus (10) for delivering metered amounts of a first fluid, such as a lubricating oil, to a remote location comprising a metering plate (36) coupled to a drive (18) for moving the metering plate between a first position in which a fluid receptacle in the metering head is filled with fluid and a second position in which the filled receptacle is placed between first and second ports for transfer of the fluid into and through a delivery line (28). The first port provides a source of a carrier fluid to drive the first fluid, while the second port is coupled to a delivery line to the remote location. The first and second ports form a portion of a manifold assembly (32, 34), which in conjunction with the metering plate comprise a metering head (figure 2). The metering head may be submerged in a reservoir whereby the receptacle is filled with a first fluid without the need for pumps or pressurization of the reservoir.
    • 一种用于将计量的第一流体(例如润滑油)输送到远程位置的装置(10),该远程位置包括联接到驱动器(18)的计量板(36),用于将计量板移动到第一位置,在第一位置 计量头中的流体容器填充有流体和第二位置,其中填充的容器被放置在第一和第二端口之间,用于将流体输送到输送管线(28)中并通过输送管线(28)。 第一端口提供载体流体源来驱动第一流体,而第二端口耦合到远程位置的输送管线。 第一和第二端口形成歧管组件(32,34)的一部分,其与计量板一起包括计量头(图2)。 计量头可以浸没在容器中,由此容器中填充有第一流体,而不需要泵或加压储存器。

    • A pump comprising: a riser with a lower inlet and an upper outlet and a downpipe with a lower outlet and an upper inlet, wherein the riser is coupled to a buoyant fluid introducing means operable in use to introduce buoyant fluid into working fluid in the riser to thereby cause the working fluid to discharge from the upper outlet of the riser, and then to pass into the upper inlet of the downpipe for delivery to the lower outlet of the downpipe; and characterised in that the lower outlet of the downpipe is in use in contained working fluid connection with the lower inlet of the riser. In this way a relatively high flow rate may be maintained through the riser and downpipe during operation of the pump when buoyant fluid is introduced into the riser.
    • 一种泵,包括:具有下入口和上出口的提升管和具有下出口和上入口的降管,其中所述提升管联接到浮动流体引入装置,所述浮力流体引入装置可用于将浮力流体引入所述提升管中的工作流体 从而使工作流体从提升管的上部出口排出,然后进入下水管的上部入口,以输送到下水管的下部出口; 并且其特征在于,所述下水管的下部出口用于与所述提升管的下部入口相连接的工作流体连接。 以这种方式,当浮力流体被引入提升管时,在泵的操作期间,可以通过上升管和下管维持相对高的流速。
