Liquid metering wheel
Abstract
Abstract THE METERING WHEEL INCLUDES AN OPEN VESSEL WITH A PARTITION WALL WHICH DEFINES ON EACH SIDE TWO CHAMBERS EACH ASSOCIATED WITH A CONSTANT-LEVEL WEIR, A METERING DISC CARRIED BY A HOLLOW ROTARY SHAFT WHICH IS ROTATABLY MOUNTED IN LEAK-TIGHT MANNER WITHIN A BEARING CARRIED BY THE PARTITION WALL AND IMMERSED IN ONE OF THE CHAMBERS. THE METERING DISC IS FORMED BY A FLAT CYLINDER WHICH COMPRISES ON THE ONE HAND AN INTERNAL CAVITY HAVING A DEVELOPMENT OF 180* WITHIN THE INTERIOR OF THE DISC AND A VOLUME WHICH IS EQUAL TO THE FLOW TO BE METERED PER COMPLETE REVOLUTION OF THE DISC AND A CONNECTING DUCT FOR PRODIVING A RADIAL COMMUNICATION BETWEEN SAID CAVITY AND THE HOLLOW SHAFT. THE DISC COMPRISES ON THE OTHER HAND A PORTION OF REDUCED THICKNESS OVER A DEVELOPMENT OF 180* WHICH IS COMPLEMENTARY TO THE DEVELOPMENT OF THE INTERNAL CAVITY, THE REDUCTION IN VOLUME OF THE DISC WITHIN SAID PORTION OF REDUCED THICKNESS BEING SUCH AS TO CORRESPOND TO ONE-HALF THE VOLUME OF SAID CAVITY.
