Description
Technical field
The utility model relates to a kind of technical field of Injection Pump, especially a kind of novel Injection Pump.
Background technique
Jerk fuel injection pump is the heart component of diesel engine; Existing Injection Pump is when work; Have impurity in the fuel oil in the entering Injection Pump, Injection Pump causes the working efficiency of Injection Pump lower because the impurity in the fuel oil causes fault easily; Influence the reliability of Injection Pump, shortened the working life of Injection Pump.
The model utility content
Existing Injection Pump reliability is low in order to overcome, working life short and ineffective deficiency, and the utility model provides a kind of novel Injection Pump.
The utility model solves the technological scheme that its technical problem adopted: a kind of novel Injection Pump; Comprise the pump housing, plunger, piston spring, following of piston spring, slotted hole, oil inlet pipe and fuel inlet fitting; Be provided with plunger in the pump housing, plunger is connected with piston spring, and the piston spring lower end is connected with following of piston spring; Following of piston spring is provided with slotted hole, and oil inlet pipe is connected with the pump housing through fuel inlet fitting.
According to another embodiment of the utility model, comprise that further following of piston spring is convex.
According to another embodiment of the utility model, comprise further being provided with filter screen in the fuel inlet fitting that filter screen is fixed in the fuel inlet fitting through fixed base.
The beneficial effect of the utility model is that this novel Injection Pump is simple in structure, compact and reasonable, and is easy to assembly quick; Connect reliably, the fuel oil that gets into Injection Pump is filtered, make that the fuel oil of Injection Pump is cleaner; Avoided Injection Pump because the impurity in the fuel oil causes fault; Prolonged the working life of Injection Pump, improved the functional reliability of Injection Pump greatly, be easy to use and promote.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. pump housings among the figure, 2. plunger, 3. piston spring, 4. piston spring is following, 5. slotted hole, 6. oil inlet pipe, 7. fuel inlet fitting, 8. filter screen, 9. fixed base.
Embodiment
Like Fig. 1 is the structural representation of the utility model, and a kind of novel Injection Pump comprises the pump housing 1, plunger 2, piston spring 3, following 4 of piston spring, slotted hole 5, oil inlet pipe 6, fuel inlet fitting 7, filter screen 8 and fixed base 9; Be provided with plunger 2 in the pump housing 1; Plunger 2 is connected with piston spring 3, and piston spring 3 lower ends are connected with following 4 of piston spring, and following 4 of piston spring is provided with slotted hole 5; Oil inlet pipe 6 is connected with the pump housing 1 through fuel inlet fitting 7; Following 4 of piston spring is convex, is provided with filter screen 8 in the fuel inlet fitting 7, and filter screen 8 is fixed in the fuel inlet fitting 7 through fixed base 9.
During use, plunger 2 is located in the pump housing 1, and plunger 2 lower ends are connected with piston spring 3; Piston spring 3 lower ends are connected with following 4 of piston spring, and following 4 of piston spring is convex, and following 4 central authorities of piston spring are provided with slotted hole 5; Improved the mechanical property of following of piston spring, oil inlet pipe 6 is connected through fuel inlet fitting 7 with the pump housing 1, be provided with fixed base 9 in the fuel inlet fitting 7; Be fixed with filter screen 8 on the fixed base 9, so that the fuel oil that gets into Injection Pump is filtered.This novel Injection Pump is simple in structure, compact and rationally, easy to assembly quick, connection is reliable; Fuel oil to getting into Injection Pump filters; Make that the fuel oil of Injection Pump is cleaner, avoided Injection Pump, prolonged the working life of Injection Pump because the impurity in the fuel oil causes fault; Improved the functional reliability of Injection Pump greatly, be easy to use and promote.
