Abstract:
1. A liquid level control system for automatically stopping the flow of a liquid fluid coming from a supply conduit or manifold, into a reservoir tank when a level of fluid in the reservoir tank has reached a predetermined height in the reservoir tank, said liquid level control system comprising: a vertical cylindrical chamber adjacently located behind a wall of said reservoir tank and hydraulically associated with said reservoir tank so that said level of fluid in said reservoir tank corresponds to a level of fluid in said vertical cylindrical chamber; a kinematic level control mechanism containing a float and an adjustable rigid link, and adapted to slide inside the vertical cylindrical chamber due to the fluid level change therein, said float secured to said portion of a float, said kinematic level control mechanics being adapted to be vertically actuated when said level of fluid in said vertical cylindrical chamber reaches a predetermined level; and, a flow control means positioned adjacent the outlet of said supply conduit or manifold and adapted to stop the flow of fluid coming from said supply conduit or manifold into said reservoir tank when said fluid within said cylindrical chamber has reached said predetermined level. said reservoir lank, has a bottom drain, along with an overflow, placed higher in said reservoir tank, then said reservoir tank, said liquid in said reservoir tank moves through the said liquid level conduit just above the bottom drain of said reservoir tank and fills said liquid level conduit from the bottom up which raises said float, which in turn moved said adjustable rigid link up to activate said manifold.
