초록 ▼

A fluid dispensing system for accurately dispensing precise aliquots of fluid rapidly and efficiently. The system includes a reservoir of fluid and a pump adapted for connection to a reservoir of fluid and for transferring precise aliquots of fluid from the reservoir to an outlet orifice. An inlet tube is provided with a bore therethrough and one open end for fluid communication with a reservoir and the other open end in fluid communication with the pump. An outlet tube is provided having a bore therethrough with one open end forming the outlet orifice for the system and the other open end in fluid communication with the pump. Controls are connected to the pump to precisely regulate the amount of fluid in an aliquot transferred from a reservoir through the inlet tube, pump and outlet tube to the outlet orifice during an operating cycle of the pump. Finally, a valve assembly is in the system associated with the inlet and outlet tubes and the pumps so as to normally close the bores in the tubes and to automatically shift to open the inlet tube while maintaining the closed outlet tube when the pump draws a precise aliquot from a reservoir. The valve assembly automatically closes the bore of the inlet tube while opening the bore of the outlet tube when the pump dispenses the precise aliquot through the outlet orifice.

A fluid dispensing system for accurately dispensing precise aliquots of fluid rapidly and efficiently comprising: a pump adapted to be connected to a reservoir of fluid for transferring precise aliquots of fluid from the reservoir to an outlet orifice for dispensing fluid from the system upon demand; an inlet tube having a bore therethrough and one open end for fluid communication with a reservoir and the other open end in fluid communication with the pump; an outlet tube having a bore therethrough and one open end forming the outlet orifice for the system and the other open end in fluid communication with the pump; control means connected to the pump to precisely regulate the amount of fluid in an aliquot transferred from a reservoir through the inlet tube, pump and outlet tube to the outlet orifice during an operating cycle of the pump; a valve assembly in the system associated with the inlet and outlet tubes and the pump so as to normally close the bores in the tubes and to automatically shift to open the inlet tube while maintaining the closed outlet tube when the pump draws a precise aliquot from a reservoir, and to automatically close the bore of the inlet tube while opening the bore of the outlet tube when the pump dispenses the precise aliquot through the outlet orifice; the inlet and outlet tubes being flexible elongated members; and the valve assembly including a supporting member, a pair of pins extending laterally from the supporting member, the inlet tube resting on one of the pins and the outlet tube resting on the other of the pins, a cam arm pivotally mounted on the support and positioned so as to normally compress the inlet and outlet tubes, the arm being slidable and pivotable so as to be moved to a first acting position wherein the inlet tube is open to permit fluid to flow therethrough while the outlet tube is retained in the closed position and the arm being movable to a second acting position where the inlet tube is retained in closed position and the outlet tube is open to permit fluid to flow therethrough.
