Abstract
A fluid actuated ball check valve assembly having an annular housing containing a ball valve. The annular housing has a first end and a second end. The annular housing defines a fluid passageway having a passageway axis extending therethrough. A fluid actuated ball valve is pivotally mounted in the fluid passageway. The ball valve defines a bore having a bore extending therethrough. Resilient members, such as a sleeve in contact with a coiled spring, engage the ball valve to maintain the ball valve in the fluid passageway. Pressurized fluid in the fluid passageway at the first end of the annular housing causes the ball valve to pivot from a closed position to an open position to allow fluid to flow through the fluid passageway from the first end to the second end of the annular housing. When pressurized fluid is not acting upon the ball valve at the first end of the annular housing and the ball valve is maintained in a closed position, fluid is prevented from flowing through the fluid passageway from the second end to the first end of the annular housing.
