Abstract: A fluid dispenser and method of operating the same. The fluid dispenser can include a wheel driven by diluent passing along a flow path in the fluid dispenser. The wheel can be connected to a pump to pump fluid from a reservoir for dispense into the diluent. In some embodiments, the ratio of wheel rotations to pump cycles is selected to provide a desired and repeatable dilution ratio of concentrated fluid to diluent. The fluid dispenser can be portable and/or disposable, and in some embodiments is adapted for installation on an upper rim of a reservoir wall. Also, the fluid dispenser can be provided with a baffle limiting the velocity and impact of incoming diluent to the wheel driving the pump, thereby improving dosing accuracy of the dispenser in some embodiments.

Abstract translation: 流体分配器及其操作方法。 流体分配器可以包括由流体分配器中的流动路径通过的稀释剂驱动的轮。 轮可以连接到泵以从储存器泵送流体以分配到稀释剂中。 在一些实施例中，选择轮转与泵循环的比率以提供浓缩流体与稀释剂的期望且可重复的稀释比。 流体分配器可以是便携式的和/或一次性的，并且在一些实施例中适于安装在储存器壁的上边缘上。 此外，流体分配器可以设置有限制进入的稀释剂对驱动泵的轮的速度和冲击的挡板，从而在一些实施例中提高了分配器的计量精度。
