FLUID CARTRIDGE

The subject matter discloses a fluid cartridge comprising a container to hold a predetermined volume of fluid, and a lid for closing the container. The lid comprises a valve-recess and an inlet valvein the valve-recess to transfer a volume of a replacement fluid in the container for replacing depleted volume of fluid in the container. A rocker valve is pivoted in the valve-recess to cover the inlet valve during a regulation phase. The rocker valve is to open the inlet valve during an actuation phase to allow the replacement fluid to enter the container. A spring element is movably disposed onthe rocker valve to control actuation of the rocker valve for opening and closing the inlet valve. The spring element slides across the rocker valve, from a regulation zone of the rocker valve to anactuation zone of the rocker valve, to open the inlet valve. 本主题公开一种流体盒，其包括用于容纳预定体积的流体的容器以及用于封闭容器的盖。盖包括：阀凹槽；和在阀凹槽中的入口阀，用于在容器中传递一定体积的替换流体，以替换容器中耗尽的流体体积。在调节阶段期间，摇臂阀在阀凹槽中枢转以覆盖入口阀。摇臂阀用于在致动阶段期间打开入口阀以允许替换流体进入容器。弹簧元件可移动地设置在摇臂阀上以控制摇臂阀的
