Abstract

A valve housing has a chamber formed therewithin, and an inlet and an outlet for accommodating fluid flow through the chamber along a given flow path.
The housing further confines a free ball therein, and hydraulic-fluid filed compartments with flexible walls. Intermediate the inlet and outlet, the housing has a valve seat formed. Fluid pressure in the chamber causes one compartment to collapse and the flexible wall of the other to expand. The expanding wall, and capturing fluid flow, moves the ball to the seat to halt flow through the chamber, after an initial period of free flow. The method comprises providing the chambered housing, disposing the ball in the chamber, communicating the inlet with a pump outlet, and confining the flexible-walled compartments in the chamber.
