[en] The metering valves currently used to dose beverages are whether fixed to a wall and big or not accurate and not safe. The goal of this work is to combine all the advantages of the two types of valves in one. This work will explain the different steps in designing an autonomous, safe and portable metering valve.
The first part of the work is dedicated to the metering valve in itself. It starts with a research work of all the possible ways to accurately dose beverages with different viscosity while still keeping a small device. After this research, the most promising pumps are designed. Several versions of these pumps are then tested to see which one is the most appropriate. Finally, a modified version of the rotary vane pump is selected.
The second part of the thesis is dedicated to the design and prototyping of the embedded electronics. For this, a PCB will be designed. This PCB drives a stepper motor, charges a battery with wireless charging and detects frauds. It also communicates with other devices and displays information on an e-ink display.
Finally, all the things developed above were able to enter a six centimeters width cube which is the maximum size possible. The pump and the electronics still needs some optimization to work perfectly but the main goal is achieved. When all the optimization will be finished, the final metering valve will be even smaller.
