Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
199 words
A DEVICE FOR THE SUPPLY AND METERING OF FUEL COMPRISING: (A) A DELIVERY TANK FOR SAID FUEL: (B) A PRESSURE BUFFER STORAGE VESSEL HAVING TWO PARTS SEPARATED BY A DIAPHRAGM, SAID FUEL IN ONE OF SAID PARTS AND A GASEOUS MEDIUM SERVING AS A BUFFER IN THE OTHER OF SAID PARTS; (C) A FEED PUMP PROVIDED WITH A FLEXIBLE DIAPHRAGM, SAID PUMP WHEN OPERATING WITH SMALL LENGTHS OF STROKE PUMPS AGAINST A HIGH PRESSURE IN SAID PRESSURE BUFFER STORAGE VESSEL; (D) A PRESSURE CONTROL DEVICE FOR AUTOMATICALLY ADJUSTING THE NOMINAL PRESSURE OF SAID FUEL IN SAID BUFFER STORAGE VESSEL BY WHICH THE EXCESS AMOUNT OF FUEL SUPPLIED BY SAID PUMP MAY BE CONDUCTED BACK TO SAID DELIVERY TANK; (E) AND A MAGNETICALLY OPERATED VALVE HAVING A SMALL STROKE AND PROVIDED WITH A CENTERING DIAPHRAGM, A VALVE NEEDLE AND AN ARMATURE; (F) SAID FUEL SUPPLIED FROM SAID DELIVERY TANK BY SAID PUMP BEING STORED IN SAID PRESSURE BUFFER STORAGE VESSEL WHICH IS VARIABLE IN SIZE SUBSTANTIALLY WITHOUT RESISTANCE, AND THE INTERMITTENT DISCHARGE OF FUEL THROUGH SAID VALVE AND THE SUBSEQUENT SUPPLY OF FUEL CAUSING PRESSURE VARIATIONS IN AMOUNTS LESS THAN 1% OF THE NOMINAL PRESSURE IN SAID BUFFER STORAGE VESSEL.
Claim 2
Independent Claim
199 words

Claim 3
Independent Claim
136 words
A METHOD FOR THE SUPPLY AND METERING OF FUEL COMPRISING SUPPLYING FUEL TO A MAGNETICALLY CONTROLLED VALVE FROM A DELIVERY TANK, SAID VALVE PASSING A PREDETERMINED AMOUNT OF FUEL TO THE INLET DURING AN OPENING PERIOD, STORING THE FUEL PUMPED FROM SAID DELIVERY TANKS AT A PRESSURE ABOVE ATMOSPHERIC PRESSURE IN A STORAGE SPACE WHICH IS KEPT UNDER PRESSURE BY MEANS OF A GAS AND VARIABLE IN SIZE SUBSTANTIALLY WITHOUT RESISTANCE, THE INTERMITTENT EXTRACTION OF FUEL THROUGH SAID VALVE AND THE SUBSEQUENT SUPPLY OF FUEL CAUSING PRESSURE VARIATIONS LESS THAN 1% OF THE NOMINAL PRESSURE IN SAID SPACE, ADJUSTING SAID NOMINAL PRESSURE BY MEANS OF A PRESSURE CONTROL DEVICE, AND SUPPLYING THE FUEL BEING KEPT READY AT NOMINAL PRESSURE WITHIN THE VALVE TO THE INLET AT SHORT AND EQUAL OPENING AND CLOSURE PERIODS OF THE VALVE.
Claim 4
Independent Claim
136 words
A METHOD FOR THE SUPPLY AND METERING OF FUEL COMPRISING SUPPLYING FUEL TO A MAGNETICALLY CONTROLLED VALVE FROM A DELIVERY TANK, SAID VALVE PASSING A PREDETERMINED AMOUNT OF FUEL TO THE INLET DURING AN OPENING PERIOD, STORING THE FUEL PUMPED FROM SAID DELIVERY TANKS AT A PRESSURE ABOVE ATMOSPHERIC PRESSURE IN A STORAGE SPACE WHICH IS KEPT UNDER PRESSURE BY MEANS OF A GAS AND VARIABLE IN SIZE SUBSTANTIALLY WITHOUT RESISTANCE, THE INTERMITTENT EXTRACTION OF FUEL THROUGH SAID VALVE AND THE SUBSEQUENT SUPPLY OF FUEL CAUSING PRESSURE VARIATIONS LESS THAN 1% OF THE NOMINAL PRESSURE IN SAID SPACE, ADJUSTING SAID NOMINAL PRESSURE BY MEANS OF A PRESSURE CONTROL DEVICE, AND SUPPLYING THE FUEL BEING KEPT READY AT NOMINAL PRESSURE WITHIN THE VALVE TO THE INLET AT SHORT AND EQUAL OPENING AND CLOSURE PERIODS OF THE VALVE.
