Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

As shown in Figure 1 to Figure 3, to meet anti-under the high inclination-angle oil-break fuel tank of one kind of the utility model, including fuel tank Ontology 1, the bottom of the oil tank body 1 are laid with several dispersion oil pipes 2, and the dispersion oil pipe 2 extends to the oil tank body 1 The horizontal minimum point of bottom and inclination minimum point, oil-feed ports of several dispersion oil pipes 2 with oil feed pump in fuel tank pass through Pipeline connection, each it is described dispersion oil pipe 2 on be arranged at intervals with several fuel feeding components 3；The fuel feeding component 3 is suitable for soaking Fluid enters in the dispersion oil pipe 3 when entering in fluid, and the fuel feeding component 3 leaks outside blocks air to enter described point when fluid It dissipates in oil pipe 2.

As a preferred solution, the fuel feeding component 3 includes fuel feeding main body 31, and the lower end of the fuel feeding main body 31 is set There is the oil inlet pipe 32 connected with the dispersion oil pipe 2, the upper end of the fuel feeding main body 31 is arranged with float 33, and the float 33 exists It floats up and down in the guiding trip segment 36 of 31 upper end of fuel feeding main body, the lower end of the float 33 is provided with sealing 34, institute It states sealing 34 to be suitable for sealing the upper end of the oil inlet pipe 32, the upper end of the fuel feeding main body 31 is provided with for limiting State the upper cover 35 that float 33 is upwardly separated from the fuel feeding ontology.

The guiding trip segment 36 is symmetrical spaced two arc vertical plates 37, and two arc vertical plates 37 enclose Into the axis of cylindrical cavity 38 overlapped with the axis of the oil inlet pipe 32, between two arc vertical plates 37 between be divided into and lead To interval 39；The float 33 is hollow structure, and the float 33 is made of the outer shroud 330 and inner circle 331 being coaxially disposed, described Outer shroud 330 is linked together with the inner circle 331 by two guide parts 332, and two guide parts 332 are located at same diameter On, the guide part 332 is arranged on described be oriented to and is spaced in 39, and the outer shroud 330 is set in the guiding trip segment 36, institute It states inner circle 331 to be arranged in the cylindrical cavity 38 that two arc vertical plates 37 enclose, the lower end of the inner circle 331 is described Sealing 34, the sealing 34 are in frustum type.

The side of left and right two of the guide part 332 is respectively arranged with a guiding ball, and the guide part 332 passes through institute It states to be oriented to the ball section opposite with two arc vertical plates 37 and roll and coordinate.

In the present embodiment, according to the shape inside oil tank body, the dispersion oil pipe of fitting tank bottoms is made, disperses oil pipe Quantity with fuel feeding component is depending on the concrete structure of tank bottoms, can extend to the minimum point that fuel tank often locates easy trapped fuel Subject to, the installation position of fuel feeding component is with reference to following 2 points：

1. the minimum point of fuel tank normal use；

2. fuel tank is in wide-angle tilt, the minimum point of fluid position.

Float 33 is placed in fuel feeding main body 31, upper cover 35 and the fuel feeding main body of 31 upper end of fuel feeding main body coordinate, will be floating Son 33, which is locked in, to be oriented in trip segment 36, and in the range of stroke, float 33 can move up and down under the buoyancy of oil.

The guide part 332 of float is set as ball with being oriented to the contact portion at interval and contacts or sphere-contact, both may be used in this way Entire surface contact can be reduced again to reduce frictional force to play position-limiting action to float or so.The ratio of float middle section setting Hermetic unit diameter is a little bit smaller, in this way can be excessive to avoid float and body contact area, causes to float and be obstructed.Float is hollow Structure can be floated by during buoyancy.Float floats rear sealing and is detached with the upper end of oil inlet pipe, at this time fluid can enter into In oil pipe；When fuel tank run-off the straight, the tank bottoms fluid of the part of tilting declines, and float declines under gravity, Sealing is by the upper end closed of oil inlet pipe so that the oil circuit mouth closing at this can avoid gas from entering in oil inlet pipe to make in this way It is inadequate into other fuel feeding component pressure, cause to be unable to oil suction.Since dispersion oil pipe extends to the position of the easy low level of tank bottoms Put, fuel tank in an inclined state when, necessarily there are other fuel feeding components to be immersed in fluid, fuel oil is from the path of fuel feeding main body lower end The supervisor of oil pump lower end is converged to, realizes and fuel feeding is carried out to oil pump.

The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or new using this practicality Type.A variety of modifications of these embodiments will be apparent for those skilled in the art, determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The most wide range consistent with features of novelty.
