Problems solved by technology

[0003] In the design of automobile fuel supply system, due to the limitations of boundary conditions, the fuel tank is designed to be flat and relatively long. At this time, if the car is on a certain slope, the oil suction pipe in the fuel tank may not be able to suck the oil in the fuel tank. Fuel, in extreme cases may cause the engine to stall, which will affect some functions of the vehicle and seriously affect the safety of the vehicle

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 As shown, in order to ensure that the fuel 102 in the fuel tank 100 can be smoothly absorbed when the vehicle goes uphill, the oil suction pipe 101 is usually arranged behind the fuel tank 100 (with the forward direction of the vehicle as the front, figure 1 The direction of the middle arrow is the forward direction of the vehicle), so as to ensure that the fuel 102 can be sucked uphill.

[0019] When the car is on a slope with a slope of α, when going downhill, the fuel 102 flows to one side due to gravity, even if the fuel tank 100 contains half a tank of fuel at this time, there is still no fuel available near the oil suction pipe 101, and the engine cannot absorb fuel. In extreme cases, the engine may stall, which will affect some functions of the vehicle and seriously affect the safety of the vehicle.

Abstract

The invention relates to an automobile oil delivery pump, in particular to a diesel oil delivery pump assembly for a gradient self-adaptation system. The oil delivery pump assembly comprises a flange,a shell and an oil delivery pump body. The oil delivery pump assembly is arranged in a fuel oil tank and located at the opposite end of an oil sucking pipe of the fuel oil tank, it can be guaranteedthat the position near the oil sucking pipe is always filled with fuel oil, and normal fuel oil supply of an engine is guaranteed. The oil delivery pump assembly is fixed to the fuel oil tank throughthe flange, the shell of the oil delivery pump assembly abuts against the interior of the bottom of the fuel oil tank, the bottom of the flange and the shell are connected through elastic connecting pipe columns, it can be guaranteed that the oil delivery pump assembly is firmly mounted in the fuel oil tank and does not shake at will along with operation of a vehicle, and under the condition thatthe plane rigidity of the metal fuel oil tank is poor, and the bottom of the metal fuel oil tank is uneven, the elastic connecting pipe columns can also compensate for the bottom unevenness of the fuel oil tank.
