Patent ID: 8920999

Claim:
A fluid injection/ejection system comprising: a first injector configured to receive a first stream of a first fluid from a source of fluid and inject the first stream of the first fluid into a first chamber; a first ejector having a venturi passage formed therein, wherein the venturi passage includes an inlet in fluid communication with the first chamber and an outlet in fluid communication with a second chamber; a check valve assembly integrated within the first ejector, the check valve assembly having a check valve passage and a valve, the check valve passage having an inlet in fluid communication with the first chamber and an outlet in fluid communication with the second chamber; a second injector configured to receive a second stream of the first fluid from the source of fluid and inject the second stream of the first fluid into the second chamber; a second ejector including a venturi passage formed therein, the venturi passage having an inlet and an outlet, wherein the inlet is in fluid communication with the second chamber; and wherein the first ejector is configured to facilitate a flow through the venturi passage formed therein and militate against a flow through the check valve assembly when a pressure in the second chamber is greater than a pressure in the first chamber, and is configured to facilitate the flow through each of the venturi passage formed therein and the check valve assembly when a pressure in the first chamber is greater than a pressure in the second chamber.
