ABSTRACT:
In accordance with an embodiment of the present invention there is provided a pump assembly used in connection with metering and dispensing fluid. The assembly includes a valve mechanism that has a first valve disc with a first opening in fluid communication with a fluid inlet of the pump assembly and with a second opening in fluid communication with an interior portion of the pump assembly. The valve mechanism also has a second valve disc with a dispensing opening and an inlet channel. The first and second valve discs are also rotatable with respect to each other between at least a dispensing position in which the second opening and the dispensing opening are aligned making dispensing of fluid possible and at least an inlet position in which the inlet channel brings the first opening in fluid communication with the second opening so that the interior portion of the pump assembly is in fluid communication with the fluid inlet of said pump assembly.
