Abstract

PURPOSE:To improve metering sensitivity by opening a nozzle for water to be metered into an impeller case in the direction tangential to the impeller, and forming spiral projecting lines or groove lines on the inside wall of the nozzle. CONSTITUTION:A nozzle 2 for water to be metered is opened to an impeller case 1 in the direction tangential to an impeller 3, and spiral projecting lines or groove lines 4 giving swirling flow to the water to be metered passing through the inside of the nozzle 2 are formed. Thereby, metering sensitivity is improved.
