Abstract
The utility model relates to a single-cylinder oil injection pump with a solenoid valve for a diesel engine, which belongs to the technical field of oil injection pumps of diesel engines. The oil injection pump comprises an oil injection pump body, an oil inlet channel which is controlled by a solenoid valve for connection and disconnection is arranged at one side of the oil injection pump body, an oil inlet pipe connector communicated with an oil inlet pipe is connected at the outer end of the oil inlet channel, and is also communicated with an air exhaust pipe extending upward. Accordingly, air entering the oil pipe after the fuel oil is used up in the previous operation of the diesel engine can be quickly exhausted through the air exhaust pipe in the next operation, thereby effectively solving the problem that the diesel engine is difficult to start up due to the air inside the diesel engine, and avoiding the problems of consequent detachment, maintenance and the like of the diesel engine.
Description
Technical field
The utility model relates to a kind of Injection Pump, and the charged magnet valve single cylinder fuel injection pump of especially a kind of use for diesel engine belongs to the diesel injection pump technical field.
Background technique
Jerk fuel injection pump is the heart component of diesel engine, and the oil inlet pipe parts are one of important spare parts of Injection Pump.During work, fuel from fuel tank arrives the oil inlet pipe parts through fuel pipe, enters the Injection Pump hyperbaric chamber, gives the burning chamber of diesel engine fuel feeding, and the oil inlet pipe parts play an important role in Injection Pump fuel feeding process.
Because existing Injection Pump oil inlet pipe is not provided with rational emptying gas passage (referring to Fig. 1 and Fig. 2), therefore in diesel engine, there is following drawback: after diesel oil uses up in the diesel oil tank, after refueling next time, there are a large amount of air in the fuel pipe (rubber hose that connects diesel oil tank and Injection Pump), get rid of very inconveniently, the result can directly cause the starting difficulty of diesel engine.
The model utility content
The purpose of this utility model is: the drawback at above-mentioned prior art exists by the architecture advances to the Injection Pump oil inlet pipe, proposes a kind of charged magnet valve single cylinder fuel injection pump of use for diesel engine that can solve the difficult row's problem of diesel engine fuel oil air in tube.
In order to reach above purpose, the charged magnet valve single cylinder fuel injection pump of use for diesel engine of the present utility model comprises the Injection Pump main body, one side of described Injection Pump main body has the oil inlet passage of electromagnetic valve break-make, the outer end of described oil inlet passage is connected to the inlet connector that is communicated with oil inlet pipe, and described inlet connector also is communicated with the outlet pipe that extends up.
Like this, diesel engine is last when once working, the air that enters oil pipe after fuel oil uses up is able to by outlet pipe very fast by emptying when working next time, has the problem of air hard-to-start, the problems such as dismounting maintenance of having avoided diesel engine therefore to cause thereby efficiently solve diesel engine because of inside.
The utility model further improves: described inlet connector is horizontally disposed with.
The utility model further improves: radially being communicated with the oil inlet pipe that extends up of described inlet connector, described outlet pipe is arranged on the outer end of inlet connector.
The utility model further improves again: the outer termination of described outlet pipe is to fuel tank.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 Fig. 2 is that the A of Fig. 1 is to part sectioned view.
Fig. 3 is an embodiment's of the utility model a structural representation.
Fig. 4 is that the A of Fig. 3 is to part sectioned view.
Embodiment
Embodiment one
The diesel engine fuel injecting pump structure of present embodiment as shown in Figure 3 and Figure 4, one side of its Injection Pump main body 4 has the oil inlet passage 6 of solenoid valve 5 control break-makes, the outer end of this oil inlet passage is connected to the horizontal inlet connector 1 that is communicated with oil inlet pipe, radially being communicated with the oil inlet pipe 2 that extends up of this inlet connector 1, the outer end of inlet connector 1 also is communicated with the outlet pipe 3 that extends up.
Like this, when diesel engine was worked, the diesel stream in the fuel tank was through fuel pipe, oil inlet pipe 2, inlet connector 1, and through electromagnetic valve, entered the hyperbaric chamber in the Injection Pump main body 4, for diesel engine work provides fuel oil.After the fuel oil in the fuel tank used up, air can be full of fuel pipe.Owing to be provided with outlet pipe 3, therefore when diesel engine starts to work next time, the air in the fuel pipe will successfully be discharged through outlet pipe 3, thereby effectively avoid diesel engine to have the problem that air is difficult to start because of inside.The outer termination of outlet pipe 3 forms the small amount of recycled oil return to fuel tank after exhaust.
Facts have proved, behind the diesel injection pump of employing present embodiment, under the prerequisite that does not influence diesel engine performance, saved the complicated processes of diesel engine dismounting exhaust, improved the working efficiency of diesel engine.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
Claims (4)
1. charged magnet valve single cylinder fuel injection pump of use for diesel engine, comprise the Injection Pump main body, one side of described Injection Pump main body has the oil inlet passage of electromagnetic valve break-make, the outer end of described oil inlet passage is connected to the inlet connector that is communicated with oil inlet pipe, it is characterized in that: described inlet connector also is communicated with the outlet pipe that extends up.
