Fuel injection pump

Abstract

Abstract A FUEL INJECTION PUMP FOR AN ENGINE WHEREIN THE RATE OF FUEL DELIVERY IS DETERMINED 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 JOINTED LEVER INTERPOSED BETWEEN THE MOVABLE MEMBER AND THE PUMP CONTROL ROD, THE JOINTED LEVER BEING RIGID IN THE FUEL QUANTITY INCREASING DIRECTION AND FOLDABLE IN THE OTHER, FUEL QUANTITY-DECREASING DIRECTION AGAINST THE OPPOSITION OF A SMALL SPRING. A SECOND, RIGID LEVER, CONNECTED TO MOVE SYNCHRONOUSLY WITH THE JOINTED LEVER, COOPERATES WITH A MAXIMUM FUEL STOP LEVER AND A BOOST RACK CONTROL LEVER. IN A FIRST DISCLOSED EMBODIMENT, THE JOINTED LEVER AND THE RIGID LEVER ARE SEPARATE, BUT BOTH ARE DRIVEN BY THE MOVABLE MEMBER. IN A SECOND DISCLOSED EMBODIMENT, THE JOINTED LEVER IS FORMED IN PAST OF A PORTION OF THE RIGID LEVER. IN BOTH THE FIRST AND SECOND EMBODIMENTS, PROVISION IS MADE FOR TEMPORARILY DISABLING THE MAXIMUM FUEL STOP LEVER WHEN THE ENGINE IS TO BE STARTED, SO THAT EXCESS FUEL MAY BE SUPPLIED TO THE ENGINE. IN A THIRD DISCLOSED EMBODIMENT, THE CONTROL ROD FOR THE ENGINE IS AUTOMATICALLY MOVED TO ITS EXCESS FUEL POSITION WHEN THE ENGINE STOPS, SO THAT THE CONTROL ROD OF THE PUMP IS IN POSITION FOR THE RESTARTING OF THE ENGINE.
