Abstract
The utility model discloses an oil supply device for a motorcycle. The utility model is characterized in that an oil return opening (5) is arranged on an oil tank (4), and an oil outlet of an oil pump (3) is communicated with a carburetor (1) by a three-way pipe (2) and is communicated with the oil return opening (5) on the oil tank meanwhile; the installation position of the three-way pipe is above the carburetor to form a drop. The utility model overcomes the phenomena of oil spill and the oil leakage of the carburetor because an inlet valve of the carburetor can not bear the pressure of fuel oil supplied by the oil pump when the installation position of the oil tank is under the carburetor, and the oil is directly supplied for the carburetor by the oil pump, so an engine of the motorcycle works normally, idle speed is stable, and accelerating speed is power. The oil supply device for a motorcycle is made according to the design theme of the utility model so as to bring a positive use effect on a motorcycle producer.
Description
Technical field
The utility model relates to the improvement invention of motor bike, and what be specifically related to is the improvement invention of motor bike fuel-feed system.
Background technology
In the prior art, the feed apparatus of motor bike also is made up of carburettor, oil pump and fuel tank.The installation site of the fuel tank in this feed apparatus is lower than carburettor, need pump fuel feed, oil pump is directly supplied carburettor to the fuel tank draw fuel, because the pressure that bears of motorcycle carburetor design-calculated inlet valve has only 0.01pa, and the pressure of this pump fuel feed reaches 0.15pa, its pressure is excessive and cause the easy oil spilling of carburettor, leakage of oil, cause motor cycle engine work mal, unstable idle speed quickens unable, and flame-out midway.
Summary of the invention
In view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of rational in infrastructure, and design science makes motor bike working properly, and idling is stable, quickens strong motor bike feed apparatus.For achieving the above object, the utility model is finished as follows: this motor bike feed apparatus includes carburettor, oil pump and fuel tank, the oil inlet of described oil pump and the oil outlet of fuel tank are connected, it is characterized in that described fuel tank is provided with return opening, the oil outlet of described oil pump is connected by three-way pipe and carburettor, and simultaneously with fuel tank on return opening connect, the installation site of described three-way pipe is higher than carburettor, forms a drop.
Of the present utility model succeeding in developing overcome because of pressure fuel pump is excessive and directly makes the inlet valve of carburettor can't bear the pressure of pump fuel feed to the carburettor fuel feeding, causes carburettor oil spilling, oil leakage phenomenon.The utility model forms a drop to the installation site of oil pump and carburettor, and pressure fuel pump is distributed in the fuel tank, and the fuel flow pressure that makes oil pump supply with carburettor reduces, thereby has guaranteed the normal operation of motor cycle engine, and idling is stable, quickens strong.According to the motor bike feed apparatus that the utility model design motif is made, will give the motor bike manufacturer with positive result of use.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is a structure principle chart of the present utility model.
The specific embodiment
Accompanying drawing has been represented structural principle of the present utility model and embodiment, further describes each relevant details of embodiment below more in conjunction with the accompanying drawings.This motor bike feed apparatus, include carburettor 1, oil pump 3 and fuel tank 4, the oil inlet 7 of described oil pump 3 is connected with the oil outlet of fuel tank 46, described fuel tank 4 is provided with return opening 5, and this return opening 5 is arranged on the flat raft position of oil outlet 6, and the oil outlet 8 of described oil pump 3 connects three-way pipe 2, outlet of three-way pipe 2 and carburettor 1 are connected, another outlet is connected with the return opening 5 on the fuel tank 4, and the installation site of described three-way pipe 2 is higher than carburettor 1, makes three-way pipe 2 and carburettor 1 form a drop.When the utility model is worked, oil pump 3 after fuel tank 4 draw fuel, by oil outlet 6 through three-way pipe 2 to carburettor 1 fuel feeding, the pressure of oil pump 3 output fuel oils is transmitted back in the fuel tank 4 by another outlet of three-way pipe 2, oil pump 3 fuel feeding keep-up pressure, stability of flow, make carburettor 1 normal operation.Through overtesting, the pressure that the utility model oil pump 1 fuel feeding produces has only 0.002pa, is significantly smaller than the pressure that carburettor 1 is born, the of the present utility model design successfully, both fuel-efficient, prolonged service life of carburettor again, compared with prior art, have substantive distinguishing features and progress.
Claims (1)
1, a kind of motor bike feed apparatus, include carburettor (1), oil pump (3) and fuel tank (4), the oil inlet (7) of described oil pump (3) is connected with the oil outlet (6) of fuel tank (4), it is characterized in that described fuel tank (4) is provided with return opening (5), the oil outlet (8) of described oil pump (3) is connected by three-way pipe (2) and carburettor (1), and simultaneously with fuel tank (4) on return opening (5) connect, the installation site of described three-way pipe (2) is higher than carburettor (1), forms a drop.
