    摘要： A modular rotary metering unit comprising: a housing having at least one liquid inlet and liquid outlet; a rotatable member arranged to rotate about a longitudinal axis thereof with respect to the housing; and at least one bore passing through the rotatable member, the or each bore having two opposing ends and a shuttle element received therein, the shuttle element being movable between two terminal positions, each towards a respective end of the bore, wherein, when the rotatable member rotates, each bore moves in communication with a liquid inlet of the housing and a liquid outlet of the housing such that liquid can be received from the liquid inlet by the bore at the one end of the bore and the shuttle element can eject liquid from the other end of the bore to the liquid outlet, wherein respective first and second engagement elements are provided at first and second ends of the unit, each of the engagement elements being rotationally linked to the rotatable member. Also disclosed is a rotary metering device comprising: a housing having at least one liquid inlet and liquid outlet; a rotatable member arranged to rotate about a longitudinal axis thereof with respect to the housing; and first and second bores passing through the rotatable member, each bore having a two opposing ends and a shuttle element received therein, the shuttle element being movable between two terminal positions, each towards a respective end of the bore, wherein, when the rotatable member rotates, each bore moves into communication with a liquid inlet of the housing and a liquid outlet of the housing such that liquid can be received from the liquid inlet by the bore at the one end of the bore and the shuttle element can eject liquid from the other end of the bore to the liquid outlet.

    摘要翻译： 一种模块式旋转计量单元，包括：具有至少一个液体入口和液体出口的壳体; 可旋转构件，所述可旋转构件被布置成相对于所述壳体围绕其纵向轴线旋转; 以及穿过可旋转构件的至少一个孔，所述孔或每个孔具有两个相对的端部和容纳在其中的往返元件，往返元件可在两个终端位置之间移动，每个朝向孔的相应端部，其中当可旋转 构件旋转时，每个孔与壳体的液体入口和壳体的液体出口连通地移动，使得液体可以通过孔的一端处的孔从液体入口接收，并且梭元件可以从液体入口 孔的另一端连接到液体出口，其中相应的第一和第二接合元件设置在单元的第一和第二端处，每个接合元件旋转地连接到可旋转构件。 还公开了一种旋转计量装置，包括：具有至少一个液体入口和液体出口的壳体; 可旋转构件，所述可旋转构件被布置成相对于所述壳体围绕其纵向轴线旋转; 以及穿过可旋转部件的第一和第二孔，每个孔具有两个相对的端部和容纳在其中的梭式元件，梭式元件可在两个端部位置之间移动，每个朝向孔的相应端部，其中当可旋转部件 每个孔转动成与壳体的液体入口和壳体的液体出口连通，使得液体可以通过孔的一端处的孔从液体入口接收，并且梭式元件可以将液体从 孔的另一端连接到液体出口。
