Abstract
A combustion ball and check valve for control of fluids through a conduit includes a unitary valve housing having a longitudinal opening extending therethrough, a ball valve closure member disposed within the housing adjacent a first end thereof and a one-way closure member disposed within the housing adjacent a second end thereof, and in relative close proximity to the ball closure member. The combination ball and check valve provides savings in weight, space and cost over conventional separate valves.
