Cam shaft for fuel injection pump |
摘要 |
A cam shaft reduces noise produced by gears used to drive cams of a fuel injection pump. Conventionally, the gear noises are caused by negative torque of a cam shaft. A cam profile of each cam which lifts a plunger of the fuel injection pump is shaped like a fan. There are formed two cams in a single cam shaft. A lift increment segment of a first cam overlaps a lift decrement segment of a second cam to prevent a negative torque.
