Abstract
The invention provides an oil sprayer. The oil sprayer comprises a fuel pipe joint, an electric appliance joint, an electromagnetic coil, a magnetic core, a valve body, a shell, a needle valve, a spring and a filter. The electric appliance joint is connected with the electromagnetic coil. The fuel pipe joint is connected with the head of the shell. The valve body is arranged inside the shell. The needle valve is arranged inside the valve body. The valve element is arranged at the front portion of the valve body. The spring is connected to the front portion of the valve element. The filter is installed on the fuel pipe joint. An inlet is formed in the end of the fuel pipe joint. According to the oil sprayer, the faults that spraying is poor, oil is dripped from a spraying hole, carbon is deposited and the needle valve is clamped will not appear.
Description
Technical field
The present invention relates to a kind of oil sprayer, belong to automobile technical field.
Background technique
During work, high pressure fuel is entered annular high voltage oil pocket in the middle part of people's needle-valve body from the oil duct of oil sprayer inlet connector through oil injector body and needle-valve body by Injection Pump, oil pressure acts on the pressure-bearing inclined-plane in the middle part of needle-valve and forms an end thrust upwards, when this thrust exceedes the pressure of pressure adjusting spring, needle-valve just on move, fuel oil, by the spray orifice of body base, sprays in people firing chamber with spray pattern.Work as failure of oil feed, when oil flow pressure declines, needle-valve is rapid return under pressure adjusting spring effect, and spray orifice is closed by the sealing cone that the sealing cone of needle-valve bottom is pressed on needle-valve body, and fuel oil stops injection.Oil atomizing is bad causes incomplete combustion, and motor accelerates unable, and single cylinder or multi-cylinder can be caused to lack fire.If the operating conditions residing for oil nozzle is very severe, mechanical load and heat load higher, the faults such as mounting and adjusting is improper in addition, often there will be spraying bad, spray orifice oil dripping, carbon distribution, and even needle-valve is stuck.Once oil nozzle breaks down, the motor of running will produce black smoke from exhaust, and each cylinder working is uneven, vibration aggravation, the anomalies such as power drop.
Summary of the invention
The invention provides a kind of oil sprayer, the above defect can be solved.
For solving above technical problem, the invention provides following technological scheme: a kind of oil sprayer, comprise fuel oil pipe connector, electrical connector, electromagnetic coil, magnetic core, valve body, housing, needle-valve, spacer, spring, filter cleaner, electrical connector connects electromagnetic coil, described fuel oil pipe connector connects housing head, is valve body in housing, is needle-valve in valve body, the front portion of valve body is spool, the anterior linking springs of spool; Fuel oil pipe connector is provided with filter cleaner, and the end of fuel oil pipe connector has import.
Further, the bottom of described housing is provided with spout, and valve body has nozzle, and nozzle connects spout.
Further, described valve body is provided with lip part.
This oil sprayer that the present invention relates to, during work, high pressure fuel is entered annular high voltage oil pocket in the middle part of people's needle-valve body from the oil duct of oil sprayer inlet connector through oil injector body and needle-valve body by Injection Pump, oil pressure acts on the pressure-bearing inclined-plane in the middle part of needle-valve and forms an end thrust upwards, when this thrust exceedes the pressure of pressure adjusting spring, needle-valve just on move, fuel oil, by four spray orifices of body base, sprays in people firing chamber with spray pattern.Work as failure of oil feed, when oil flow pressure declines, needle-valve is rapid return under pressure adjusting spring effect, and spray orifice is closed by the sealing cone that the sealing cone of needle-valve bottom is pressed on needle-valve body, and fuel oil stops injection.
Accompanying drawing explanation
Fig. 1 is a kind of fuel injector structure figure of the present invention.
Embodiment
As shown in Figure 1, oil sprayer comprises fuel oil pipe connector 1, electrical connector 2, electromagnetic coil 3, magnetic core 4, valve body 6, housing 7, needle-valve 8, spacer 9, spring 11, filter cleaner 12, electrical connector 2 connects electromagnetic coil 3, described fuel oil pipe connector 1 connects housing 7 head, be valve body 6 in housing 7, be needle-valve 8 in valve body 6, the front portion of valve body 6 is spool, the anterior linking springs 11 of spool; Fuel oil pipe connector is provided with filter cleaner 12, the end of fuel oil pipe connector 1 has import.
The bottom of described housing 7 is provided with spout, and valve body has nozzle, and nozzle connects spout 13.
Described valve body 6 is provided with lip part.
In figure, needle-valve forms distance 5, and housing is also connected with spacer 10.
Embodiment of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
