THE LIQUID PUMP IS DESIGNED TO PUMP THE LIQUID IN THE WELL OF THE CONTAINER UP THE HOLLOW STEM WHERE IT FALLS ONTO AND THROUGH A COFFEE BASKET SUPPORTED NEAR THE UPPER END OF THE STEM. A BY-PASS PASSAGEWAY INTERCONNECTS THE PUMP WELL CHAMBER AND THE LIQUID CONTAINER, WHICH PASSAGEWAY MAY SELECTIVELY BE PARTIALLY OR COMPLETELY OPENED TO PREVENT A SELECTED PORTION OF THE LIQUID PASSING INTO THE CHAMBER FROM BEING FED UP THE STEM AND THROUGH THE COFFEE BASKET, THEREBY CONTROLLING THE STRENGTH OF THE BREW.
