Abstract
The utility model belongs to a mechanical engineering relates to diesel engine fuel oil system.
A driver of oil sprayer is composed of casing, plunger and plunger return spring, and features that the top of casing is connected to high-pressure oil pipe and another end of high-pressure oil pipe is connected to high-pressure oil pump. The lower end of the shell is connected with the upper end of the oil injector. The plunger and the injector plunger are processed into a whole and are arranged in the injector body. When the plunger of the high-pressure oil pump moves upwards, high pressure generated in the high-pressure oil pipe pushes the plunger to move downwards so as to enable the oil sprayer to work.
Description
The utility model belongs to mechanical engineering, relates to diesel fuel system.
Existing pump---oil sprayer and PT oil sprayer rely on the mechanical driving mechanism of compositions such as injection cam, swing type tappet, push rod, rocking arm, adjustment screw, lock nut to drive, this driving mechanism structure complexity, be difficult for adjusting, improperly can make the oil sprayer atomization badness if adjust, cause engine performance to descend, and can break the oil sprayer mouth.
Provide a kind of fuel injector driver order of the present utility model, solve existing pump---the complicated and difficult phenomenon of adjusting of oil sprayer and PT oil sprayer driving mechanism.
The utility model is made up of plunger, housing, plunger return spring etc., plunger is a cylindrical structure, can be in housing axially reciprocating, all the big and housing top precision of diameter is movingly on it, the big end of plunger has a limit dais, plunger shape that the plunger lower end can require according to different oil sprayers and oil sprayer plunger are processed into one and are installed in the oil sprayer with it precision movingly, and housing is a bicylindrical shape structure, and little bottom, top is big.
Take out the outlet valve and the spring of high pressure oil pump during installation.Actuator housing top and high-pressure oil pipe are connected, and the high-pressure oil pipe the other end and high pressure oil pump are connected, and housing lower end and oil sprayer join.Plunger return spring is pushed into the top with plunger before the work.The high pressure oil pump plunger is up when oil sprayer needs pressure descending, and high-pressure oil pipe and plunger head produce the pushed at high pressure plunger and move downward.When oil sprayer plunger needs were up, the high pressure oil pump plunger was descending.High-pressure oil pipe and plunger head high pressure reduce, and the fuel injector driver plunger is made under of up at return spring.
The utility model and existing pump---oil sprayer is compared with PT oil sprayer mechanical driving mechanism, need not use complicated swing-bar mechanism and pressure regulation device, lightweight construction, and functional reliability is strong, and it is easy to maintenance easy to use.
