Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a coil of wire positioned proximate the valve member such that the valve member moves between a seated position and an unseated position relative to an orifice in response to energizing the electromagnet. A connector coupled to the housing includes an inlet tube concentrically aligned with and surrounding a return tube. The inlet tube is adapted to receive pressurized reagent from a source of reagent. The return tube is adapted to return reagent to the source.

Abstract translation: 用于注射试剂的注射器包括定位在壳体内的可轴向平移的阀构件。 电磁体定位在壳体内，并且包括定位在阀构件附近的线圈，使得阀构件响应于激励电磁体而相对于孔口在就座位置和不相对位置之间移动。 耦合到壳体的连接器包括与回流管同心对准并围绕回流管的入口管。 入口管适于从试剂源接收加压试剂。 返回管适于将试剂返回到源。
