Fuel injection pump

Abstract

Abstract A FUEL INJECTION PUMP WHEREIN THE RATE OF FUEL DELIVERY IS DETERMINED BY A PUMP CONTROL ROD WHICH IS ADJUSTED BY A GOVERNOR ACTING UPON A MOVABLE PUMP CONTROLLING MEMBER IN OPPOSITION TO A HEAVY SPRING VARIABLY TENSIONED BY THE ENGINE THROTTLE. THE PUMP INCLUDES A CONNECTING UNIT INTERPOSED BETWEEN THE PUMP CONTROL ROD AND A LINKAGE EXTENDING FROM THE MOVABLE MEMBER, THE CONNECTING UNIT HAVING A SLIDE WHICH IS CONNECTED TO THE CONTROL ROD BY SPRING MEANS WHEREBY THE LATTER TRANSMITS MOTION FROM THE SLIDE TO THE CONTROL ROD IN THE FUEL QUANTITY INCREASING DIRECTION WHILE PERMITTING MOTION OF SAID ROD IN FUEL DECREASING DIRECTION RELATIVE TO THE SLIDE. MEANS RIGIDLY CONNECTED TO THE LINKAGE AHEAD OF THE SLIDE COOPERATES WITH A MAXIMUM FUEL LEVER. MEANS RIGIDLY CONNECTED TO THE CONTROL ROD, BUT YIELDABLY CONNECTED TO THE SLIDE THROUGH SAID SPRING MEANS, SELECTIVELY COOPERATES WITH A FUEL SHUT OFF LEVER AND WITH A BOOST RACK CONTROL LEVER, WHEREBY BOTH SUCH LATTER LEVERS NEED OVERCOME ONLY SAID SPRING MEANS IN ORDER TO MOVE THE CONTROL ROD IN ITS FUEL DECREASING DIRECTION. THE PUMP IS ALSO PROVIDED WITH MEANS FOR TEMPORARILY DISABLING THE MAXIMUM FUEL STOP LEVER AND THE BOOST RACK CONTROL LEVER WHEN THE ENGINE IS TO BE STARTED, SO THAT EXCESS FUEL MAY BE SUPPLIED TO THE ENGINE.
