摘要
The invention in question relates to a needle-type stepped cylindrical stopper for automatic control of water consumption in pipelines, of two types, each type having two sections for automatically controlling water consumption, irrespective of the water pressure in the line or when the taps are opened, for use in automatic water-saving devices and pressure-sensitive flow controllers, such as to enable, with a single automatic water-saving device, incorporating the needle-type stepped stopper of this invention, automatic control of minimum water consumption, from 4.0 liters per minute as a minimum at a maximum static pressure of 0.2 kilograms per square centimeter up to a maximum water consumption of 10.0 liters per minute at a maximum static pressure of 6.0 kilograms per square centimeter.
