ABSTRACT:
A fluid-dispensing system is disclosed. The dispensing system comprises an apertured base, a hollow cylinder, an apertured piston, an orificed overcap, a fluid passageway, an apertured extension, and three valves. The piston, slidably engageable within the cylinder, divides the cylinder into two chambers. The cylinder defines a hollow neck at one end portion thereof. The overcap defines an apertured throat that is slidably engageable within the cylinder neck. The throat aperture of the overcap provides fluid communication between one cylinder chamber and a fluid-mixing region spaced from the fluid-dispensing system. The fluid passageway, disposed through the piston aperture, provides fluid communication between a pressurized-fluid source and the fluid-mixing region via at least one orifice of the overcap. The base defines an apertured sleeve. The hollow extension, slidably engageable within the sleeve, is in fluid communication with the one overcap orifice via the fluid passageway. At least one aperture of the extension, when disposed in the sleeve, is alignable with an aperture of the sleeve. The first valve, carried by the base, is utilized to controllably affect flow of a pressurized fluid from the pressurized-fluid source to the fluid passageway. The second valve, provided by relative movement between the extension and the sleeve, is utilized to controllably affect flow of the pressurized fluid between the fluid passageway and the other of the two cylinder chambers. The third valve, provided by relative movement between the cylinder neck and the overcap throat, is utilized to controllably affect flow between the other cylinder chamber and the fluid-mixing region.
