Abstract
The utility model discloses an external electric spraying oil pump of a motorcycle, which comprises an oil pump top cap (2) with an oil inlet (1), wherein a floating oil plug device is arranged in the cavity (3) of the oil pump top cap (2) oppositely to the oil inlet (1), and an air balance hole (4) is formed on the oil pump top cap (2) in parallel to the oil inlet (1). The external electric spraying oil pump has the advantages of skillful structural design and convenience for manufacture and installation; by adopting the external electric spraying oil pump, bubbles caused by operation of the oil pump can be eliminated, and the choke is prevented, so that fuel oil can normally reach the oil pump.
Description
Technical field
The utility model relates to a kind of motorcycle, and particularly a kind of motorcycle is with the external oil pump of EFI.
Background technique
At present, existing motorcycle is to utilize action of gravity with the structural principle of external oil pump; The fuel from fuel tank oil outlet flows to the oil pump filler opening through pipeline; Fuel oil self also can produce certain bubble under bubble and the higher temperature conditions but can produce when working because of oil pump, and adding between the filler opening of top tank oil outlet to external EFI oil pump has one section oil pipe distance, therefore very easily produces vapour lock; Thereby cause fuel oil can not normally arrive oil pump, oil pump can't pump oil.
The model utility content
The purpose of the utility model just provides a kind of motorcycle that can eliminate vapour lock with the external oil pump of EFI.
The purpose of the utility model is to realize through such technological scheme; A kind of motorcycle is with the external oil pump of EFI; Comprise the oil pump loam cake that has filler opening; Relatively filler opening is provided with the stifled oily device that floats in the cavity of oil pump loam cake, saidly on oil pump, covers parallel filler opening and is provided with the air balance hole.
Wherein, The said stifled oily device that floats comprises the float of the hollow in the cavity that is arranged on the oil pump loam cake; Between float and filler opening, be provided with the needle-valve body assembly that penetrates in the pintle valve seat; Said pintle valve seat is positioned at the receiving cavity that is convexed into by the oil pump loam cake, saidly is provided with the needle valve movement support in needle-valve body assembly lower end.
Further, said needle-valve body assembly comprises valve body and the valve point that is wholely set, and said valve point is taper, and corresponding valve point is provided with the conical surface that matches with the valve point on said pintle valve seat.
In order to prevent leakage of oil, said end face at the oil pump loam cake is provided with seal ring.
Owing to adopted technique scheme, the utlity model has structural design ingenious, make convenient installation, adopt it can eliminate because the bubble that oil pump work is brought prevents the generation of vapour lock, make fuel oil normally arrive oil pump.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these mode of executions; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment: as shown in Figure 1; A kind of motorcycle is with the external oil pump of EFI; Comprise the oil pump loam cake 2 that has filler opening 1, relatively filler opening 1 is provided with the stifled oily device that floats in the cavity 3 of oil pump loam cake 2, said on oil pump loam cake 2 parallel filler opening 1 be provided with air balance hole 4.
Wherein, The said stifled oily device that floats comprises the float 5 of the hollow in the cavity 3 that is arranged on oil pump loam cake 2; Between float 5 and filler opening 1, be provided with the needle-valve body assembly that penetrates in the pintle valve seat 6; Said pintle valve seat 6 is positioned at the receiving cavity 7 that is convexed into by oil pump loam cake 2, saidly is provided with needle valve movement support 8 in needle-valve body assembly lower end.
Further, said needle-valve body assembly comprises the valve body 9 and valve point 10 that is wholely set, and said valve point 10 is taper, and corresponding valve point 10 is provided with the conical surface that matches with valve point 10 on said pintle valve seat 6.
The working principle of the utility model is such: after the fuel oil in the motorcycle mailbox just gets into oil pump loam cake 2 from filler opening 1; From getting between pintle valve seat 6 and needle-valve body assembly in the oil pump body; And float 5 is owing to action of gravity at this moment, and its bottom contacts with the bottom of oil pump loam cake 2; When fuel oil increases in oil pump loam cake 2 bottoms gradually; Because buoyancy of liquid effect; Float 5 assemblies can move upward along oil pump loam cake 2 walls; When the valve point that moves to the needle-valve body assembly 10 contacts with the conical surface of pintle valve seat 6 when also compacted, can block fuel oil from filler opening 1 oiling in oil pump loam cake 2; When oil pump was worked, oily plane descended, and the valve point 10 of needle-valve body assembly unclamps the gap with the conical surface of pintle valve seat 6; Fuel oil can get into oil pump loam cake 2 from filler opening 1 smoothly, and after oily plane rose to certain altitude, the valve of needle-valve body assembly point 10 contacted also compacted with the conical surface of pintle valve seat 6; The blocking-up fuel oil gets into, and so repeatedly, can make fuel oil in oil pump loam cake 2, remain on relatively-stationary liquid level height; Owing to air equalizing orifice 4 is arranged at the top of oil pump loam cake 2; The pasta upper part communicates with air, can eliminate the intrasystem bubble of oil-feed fully, thereby realizes eliminating the purpose of vapour lock.
In the utility model, in order to strengthen the sealing of oil pump loam cake and oil pump, said end face at oil pump loam cake 2 is provided with seal ring 11.
