ABSTRACT:
A piston-powered fluid dispensing system is disclosed. The fluid dispensing system comprises an apertured base, a hollow elongated cylinder, an apertured piston, a hollow orificed overcap, an elongated fluid passageway, an externally-channeled hollow extension, and three valves. The elongated cylinder, which defines a longitudinal axis, carries the base at one end portion and defines a hollow neck at the opposite end portion. The piston, disposed in the cylinder for providing two cylinder chambers, defines a circumferential portion that is slidably engageable with the cylinder substantially along the length of an inner surface. The overcap, carried by the cylinder and rotatable about the longitiudinal axis, defines an internal fluid-mixing region and a throat that is in fluid communication with the fluid-mixing region. The throat, carrying the externally-channeled extension, is slidably engageable with an inner surface portion of the cylinder neck. The extension, also slidably engageable with the inner surface portion of the cylinder neck, carries the fluid passageway and provides fluid communication between the fluid passageway and the fluid-mixing region. At least one external channel of the hollow extension is able to provide fluid communication between one cylinder chamber and the fluid-mixing region. One valve is carried by the base. A second valve, carried by the fluid passageway, abuttingly engages the first valve. A third valve, provided by relative movement between the extension and neck, controllably affects flow between the one of the two cylinder chambers and the fluid-mixing region.
