A fluidically controlled refill system which automatically maintains the flow of the refill fluid until a predetermined liquid level or fluid pressure is achieved in the container to be filled. The system includes a diaphragm which interacts with the main valve to hold the valve in the open position during the filling operation, and a fluid switching device which causes the pressure on the diaphragm to decrease in response to predetermined conditions and thus close the main valve.
