Fluid metering and distributing system

Abstract

Abstract A SHUTTLE-PISTON TYPE OF FLUID METERING DEVICE IN WHICH THE LENGTH OF STROKE OF THE SHUTTLE PISTON IS ADJUSTABLE BY CONTROL OF THE POSITION OF THE PISTON FOR WHICH ONE ENDCHAMBER OF THE CYLINDER BECOMES CLOSED TO ARREST THE PISTON STROKE. PREFERABLY THE DISCHARGE PATH FOR SAID CHAMBER EXTENDS THROUGH A PAIR OF ADJACENT AXIALLY DISPOSED AND DISPLACED BORES IN THE PISTON, THESE TWO BORES BEING BRIDGED DURING TRAVEL OF THE PISTON BY AN ANNULAR PASSAGEWAY IN AN EXTERNAL AXIALLY-POSITIONABLE CONTROL MEMBER. WHEN THE PISTON REACHES A PREDETERMINED POSITION IN THE CYLINDER, THE EXTERNAL INTERCONNECTING PASSAGEWAY IS THEREBY BLOCKED AND THE CORRESPONDING END-CHAMBER THEREBY SEALED OFF TO PROVIDE ARREST OF THE PISTON TRAVEL. THE AXIAL POSITION OF THE EXTERNAL MEMBER CONTAINING THE ANNULAR PASSAGEWAY THEREFORE CONTROLS THE LENGTH OF STROKE OF THE PISTON AND THE AMOUNT OF FLUID PUMPED PER STROKE OF THE PISTON. A SYSTEM ADAPTABLE TO SUPPLY FUEL TO ANYWHERE FROM ONE TO TWELVE ENGINE CYLINDERS EMPLOYS THREE SUCH FLUID-METERING DEVICES SUPPLYING TWO SYNCHRONIZED FLUIDDISTRIBUTING SHAFTS TO PRODUCE TWELVE OUTPUTS, VARIOUS GROUPS OF WHICH OUTPUTS CAN BE USED DEPENDING UPON THE NUMBER OF CYLINDERS IN THE PARTICULAR ENGINE.
