Abstract

PURPOSE:To carry out constant operation of a small time constant (high response speed) by providing a rectifier at its bottom with a cylinder of a sectional area smaller than that of the rectifier and by attaching a liquid outlet to the cylinder at its bottom, and by setting in the cylinder a spherical float which moves up and down correspondingly to the rise and fall of the liquid level.
