Description
Technical field
The utility model relates to spring technology, particularly a kind of spring pillar Injection Pump.
Background technique
Spring is a kind of mechanical parts utilizing elasticity to carry out work.General spring steel is made.Utilize its elasticity can control parts motion, relax impact or vibrations, stored energy, measuring force size etc.Be widely used in machine, instrument.Stressed and the distortion of spring meets Hooke's law, namely stressedly need be directly proportional to deformation quantity.
In recent years along with the raising of domestic industry level, diesel engine makes great progress on the workmanship of component, but day by day in short supply along with the constantly strict of tail-gas law and petroleum-based energy, makes for diesel emission standard and more and more stricter to the requirement of economical engine.In addition, Injection Pump is the vitals of diesel engine, and diesel engine to the requirement of Injection Pump is: can ensure the continuous of oil spout and force feed process, ensures the raising of fuel pressure, ensures the combustion efficiency of fuel oil, reaches emission standard.But in the prior art, often cannot meet these requirements simultaneously, therefore need to design a kind of spring pillar Injection Pump.
Summary of the invention
It is simple that technical problem to be solved in the utility model is to provide one to have structure, easy to use and oil-proof spring pillar Injection Pump.
For solving the problem, the utility model adopts following technological scheme:
A kind of spring pillar Injection Pump, comprise high pressure oil base, the pump housing and quantity control structure, described high-pressure oil pipe seat is positioned at the top of the pump housing, and fix with the pump housing, described quantity control structure is positioned at the right side of the pump housing, described high pressure oil base is provided with oil connection and fuel-displaced spring, described oil connection is positioned at the upper end of high pressure oil base, described fuel-displaced spring is positioned at the inside of high pressure oil base, the described pump housing comprises delivery valve seat, plunger, roller and cam, described delivery valve seat is positioned at the upper end of plunger, described plunger comprises plunger bushing, piston spring and outlet valve, the bottom of described plunger is provided with base, described roller connects the bottom of plunger, described roller is connected with cam.
As preferably, described fuel-displaced spring connects delivery valve seat, is conducive to controlling delivery valve seat by fuel-displaced spring and carries out fuel-displaced.
As preferably, described high pressure oil base and pump housing contacting point are provided with seal washer, are conducive to preventing high pressure oil base from contacting with the pump housing tight, cause leakage of oil situation.
As preferably, the right side of the pump housing is provided with plunger bushing, is conducive to non-movable piston by plunger bushing.
As preferably, described quantity control structure connects base, is conducive to the oil pump capacity on control connection seat, avoids lasting a large amount of fuel-displaced, causes the wasting of resources.
The beneficial effects of the utility model are: owing to being provided with high pressure oil base, are conducive to carrying out sealing to the pump housing and fix, owing to being provided with fuel-displaced spring, being conducive to controlling delivery valve seat carries out regular fuel-displaced, owing to being provided with plunger, be conducive to the transmission carrying out oil, owing to being provided with piston spring, be conducive to controlling plunger motion oil transportation, owing to being provided with roller and cam, plunger can being controlled and move up and down, regular fuel-displaced, owing to being provided with consumption control structure, be conducive to controlling oil pump capacity.
Accompanying drawing explanation
