Abstract
The utility model discloses an automatic air exhausting and fuel supply device for a motorcycle. A fuel filter installed between a fuel tank and a carburetor is provided with an air exhausting port, and the air exhausting is connected with a vent pipe led to the upper part of the fuel tank. The utility model adopts a three-way type fuel filter structure, and air going into the filter can be timely exhausted outside; the fuel spply effect can be effectively improved, the phenomenon of insensitiveness of a motorcycle engine at the time of starting and acceleration can be eliminated, the service life of the whole automatic can be extended.
Description
The utility model relates to a kind of device, especially relates to a kind of automatic emptying device of air that is used for motor bike.
At present both at home and abroad in the motorcycle fuel system, fuel oil strainer is housed all between fuel tank and the carburettor, influences vehicle performance and service life to prevent in the fuel oil in the impurity and fuel tank iron rust etc. to enter carburettor.But existing fuel oil strainer refuels under empty fuel tank state in motor bike gas filed process especially, and air very easily enters fuel oil strainer, forms certain pressure, causes the fuel feeding sluggishness, causes the motor bike starting and quickens ineffectively, and driving engine shortens service life.
The purpose of this utility model is to provide a kind of fuel line fuel feeding sensitivity, the unobstructed automatic emptying gas of motor bike feed apparatus of guaranteeing.
The technical solution of the utility model is: the automatic emptying gas of a kind of motor bike feed apparatus, comprise that fuel tank, fuel tank bottom have fuel tank from suction switch, the fuel tank oil outlet pipe is connected with fuel oil strainer, the fuel-displaced pipeline of fuel oil strainer is connected with carburettor, the fuel-displaced pipeline of carburettor passes to driving engine, be provided with air outlet on fuel oil strainer, described air outlet is connected with the breather pipe that leads to fuel tank top.
The fuel oil strainer bottom has installation foot, is in upper position with the air outlet that guarantees fuel oil strainer.Have lining ring on the installation foot.
The utility model adopts three way type fuel oil strainer structure, makes the air that enters filter in time to discharge, and the fuel feeding effect is significantly improved, and eliminates motor cycle engine in starting, the ineffective phenomenon that occurs when quickening, improves car load service life.Simultaneously, the utility model structure is very simple, does not increase cost basically, has good practicability.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation;
Fig. 2 is a fuel oil strainer structural representation shown in Figure 1.
As figure, the motor bike feed apparatus, form by fuel tank 1, fuel oil strainer 11, carburettor 5, airfilter 6, fuel tank 1 bottom has fuel tank from suction switch 11, fuel tank oil outlet pipe 10 is connected with fuel oil strainer 12, and the fuel-displaced pipeline 7 of fuel oil strainer 12 is connected with carburettor 5, is connected to airfilter 6 before the carburettor 5, the fuel-displaced pipeline 4 of carburettor 5 passes to driving engine, to engine oil.The fuel-displaced pipeline 4 of carburettor 5 and fuel tank are connected to negative pressure pipe 3 between suction switch 11.
On fuel oil strainer 12, be provided with air outlet 13, described air outlet 13 is connected with the breather pipe 2 that leads to fuel tank 1 top, the air that enters fuel oil strainer 12 is discharged into fuel tank 1 automatically, makes fuel oil pass through the filtration of fuel oil strainer 11 smoothly, enters carburettor 5.
