ALTERNATIVE DIAPHRAGM PUMP WITH PNEUMATIC CONTROL AND DIRECTION INVERSION MECHANISM FOR ALTERNATIVE PUMP

摘要

THE INVENTION RELATES TO AN ALTERNATIVE DIAPHRAGM PUMP. /P P ACCORDING TO THE INVENTION, TWO PUMPING DIAPHRAGMS ARE MOUNTED AT THE OPPOSITE ENDS OF A SHAFT ON WHICH CAN SLIDE A CALIPER WHICH CARRIES SPRINGS 36 MOUNTED AROUND THEM. AXES 37. WHEN THE SHAFT BEARING THE DIAPHRAGMS IS MOVED DUE TO THE TRANSMISSION OF COMPRESSED AIR FROM A FIRST SIDE OF THE DIAPHRAGM, THE SHAFT MOVES AND, NEAR THE END OF ITS STROKE, DRIVES A CALIPER SO ALTHOUGH THAT SPRINGS 36 ARE QUICKLY RELEASED AND PUSH BACK THE CALIPER WHICH CONTROLS A DISTRIBUTOR WHICH INVERTS THE TRANSMISSION OF COMPRESSED ENGINE AIR TO THE DIAPHRAGMS. /P P APPLICATION TO PUMPS OF FOOD SYRUPS.
