Patent ID: 7661604

Claim:
A system for accurate dosing and dispensing of a predetermined liquid material, comprising: a housing for receiving a pressurized fluid stream, the housing having an inlet, an outlet, and an intermediate portion extending therebetween and defining an admission port for admitting the predetermined liquid material; a measuring container operably coupled to the housing for segregating from a source a preselected portion of the liquid material to be dispensed, the measuring container including a containment vessel having at least a partially transparent sight glass portion; a selectively operable valve assembly disposed in a flow path defined through the housing, the valve assembly including: a flow control valve selectively operable to alternatively permit or stop a flow of the pressurized fluid through the housing, and a function selection valve operable to selectively set one of a plurality of functional configurations for guiding the liquid material; and, a holding container operably coupled to the function selection valve, for storage of the predetermined liquid material, the holding container being selectively disposed in open communication with the measuring container and the flow of pressurized fluid responsive to the function selection valve; wherein the measuring container in a first of the functional configurations is disposed in open communication with the flow of pressurized fluid through the housing, and in a second of the functional configurations is isolated therefrom.
