ABSTRACT:
Liquid dispensing apparatus particularly for beverages has a transparent measuring chamber capable of receiving in mounting engagement an inverted bottle in communication with the measuring chamber. The chamber includes a liquid inlet port, a liquid outlet port and a downwardly resiliently biased sliding tubular valve member mounted in the outlet port. A pivotal operating member serves to urge the valve member upwards to close the inlet port, present lateral triangular apertures in the valve member to the interior of the chamber to permit liquid to pass therethrough and out through the outlet port, and open an air valve at the upper end of the valve member to permit air to enter the chamber displacing liquid leaving the chamber. An electric motor and associated gearing may be provided for raising the valve member.
