Abstract:
1. A liquid dispensing apparatus comprising: a first vessel configured to be filled with a liquid; a second vessel configured to be filled with the liquid; a flow passage connecting said first and second vessels, the flow passage constructed and arranged to enable the liquid to flow between the first and second vessels; a valve coupled with the flow passage, the valve configured for dispensing the liquid from the flow passage; a first pressurizing device configured to apply a first pressure to the liquid in the first vessel; a second pressurizing device configured to set a second pressure of the liquid in the second vessel; and a first flow rate restricting member disposed in the flow passage; and a second flow rate restricting member disposed in the flow passage; wherein the first and second flow rate restricting member are configured to regulate a flow rate of the liquid flowing in the flow passage between the first and second vessels when the first and second pressuring devices are operated such that the first pressure applied to the liquid in the first vessel differs from the second pressure applied to the liquid in the second vessel.
