ABSTRACT:
A fluid flow assembly includes a storage container connected to a fluid coupling and retaining cylinder. The connection is secured by a bayonet connection and walls between the bases of the container and cylinder. The storage container has a ball valve assembly disposed at its base, which includes an upper housing, a lower extension, and a ball valve axially disposed therein. The cylinder includes an axial hollow elongate fluid outlet on the base, co-axially aligned with an outlet port of the ball valve assembly of the container. The upper portion of the fluid outlet is a male coupling, which penetrates into the outlet port, when the container is connected to the cylinder, and axially displaces a valve ball from its closed position into an open position, enabling fluid flowing thru the ball valve assembly of the storage container, into the hollow fluid outlet of the cylinder, and downstream of it.
