The specific embodiment
As shown in Figure 1, 2, 3, the front end of oil guide pipe 10 is provided with the filler neck conduit 5 of nozzle, and conduit 5 is connected with filling pipe cap 7, and an end is provided with the anti-outer device 11 that spatters in the oil guide pipe of oil guide pipe 10, and the other end is provided with check valve 100 in the oil guide pipe.
As shown in Figure 4, spatter device 11 outside anti-and comprise the oil proof rubber elastic body 2 that is connected and fixed with oil guide pipe 10 outer casing inner walls, oil proof rubber elastic body 2 leading portions are cylindrical, back segment is taper type, oil proof rubber elastic body 2 is provided with guide hole 3, the fuel filler pipe mouth of pipe that guide hole 3 interior fluidisations are connected with nozzle inserts cooperation sleeve pipe 4, large 1～2 millimeter than the external diameter of the fuel filler pipe mouth of pipe of sleeve pipe 4 internal diameter.Sleeve pipe 4 front ends are provided with protection flange 6, and protection flange 6 is connected with oil proof rubber elastic body 2 end faces.
Shown in Fig. 5,6,7, radial strut 104 middle parts of " ten " font are provided with orienting sleeve 105, and pilot bar 106 passes orienting sleeve 105, the end of pilot bar 106 be provided with can with the valve plate 107 of valve cup ring one-way sealing; Pilot bar 106 is provided with spring positive stop lug boss 108, and the spring positive stop lug boss 108 in the present embodiment is that the set collar that connects on the pilot bar 106 consists of.Retracing spring 109 is enclosed within on the pilot bar 106, spring positive stop lug boss 108 end contacts on retracing spring one end and the pilot bar, and the retracing spring other end contacts with the end face inwall 110 of orienting sleeve.
Radially pin 102 is relative with pilot bar 106, and the block that the middle part 111 of the radially pin 102 of " ten " font forms in the present embodiment is relative with pilot bar 106, when refueling, avoids ducted fuel oil to the impact of pilot bar 106 like this.
When this valve is in when being subject to liquid fuel in the fuel oil filling system and impacting, spring can compress because of being subject to impacting, valve plate 107 unlatchings, and fuel oil can enter fuel tank by the gap between valve plate 107 and the valve cup ring 103 by diversion shell 101 runners smoothly; When refueling end, along with reducing of input pressure, the amount of compression of spring reduces gradually, returns to drift, and this moment, the fuel tank refueling process finished, and valve plate 107 is closed.In the process of filling, do not have liquid fuel reverse outflow in the check valve.Above-mentioned check valve and anti-outer spatter embedded being installed on of device and lead in the oiling tube is located at and has solved check valve volume and anti-outer Layout Problem of spattering device in the oil guide pipe.
