INJECTION PUMP MOUNTED WITH LEVER-TYPE GOVERNOR ELECTRONIC CONTROL UNIT

摘要

PURPOSE: An injection pump mounted with a lever-type governor electronic control unit is provided to make an engine operate at constant speed by improving control response property and supplying the injection amount of fuel supplied to a combustion chamber, according to a load change. CONSTITUTION: An injection pump mounted with a lever-type governor electronic control unit has a drive shaft(30) in which a drive gear(32) is mounted; a governor(40) connected to the drive gear; a governor lever assembly connected to the governor; and a housing(20) having a slide hole(54b) and a bolt hole(54a) to mount a pull rod adjust bolt selectively controlling a collector lever of the governor lever assembly. The injection pump comprises a contact part(110), a drive part(130), and a lever part(160). The contact part has a bracket(112) the outer peripheral surface of which covers the inner peripheral surface of the bolt hole, and a contact sleeve one end of which is in a close contact with the collector lever through the bracket and the other end of which is extended to the outside of the housing, through the slide hole. The drive unit has a mounting plate mounted to the housing in a state of covering the outside of the slide hole; a support plate(142) integrally formed at the upper part of the mounting plate and vertically extended upward; and an electronic actuator(154) mounted to the support plate. The lever part has a revolving shaft(162) mounted to the support plate; a buffering member mounted to the support plate; and an operation lever(180) mounted to the revolving shaft, to hit the contact sleeve by the operation of the electronic actuator.
