Class Information
Number: 137/101.11
Name: Fluid handling > Self-proportioning or correlating systems > Self-proportioning flow systems > Flow comparison or differential response > Main line flow displaces or entrains material from reservoir
Description: Subject matter wherein a shunt line having a reservoir therein relies on the pressure difference between its connection to the main line to cause flow therethrough to entrain material in the reservoir, or to displace the reservoir material or an intermediate distinct fluid layer or expansible chamber device whereby the reservoir material is forced into the main line without mixing with the flow while in the shunt.
