Abstract
The utility model provides a three-way pipe connector for oil supply apparatus of vehicle, comprising the oil entering end of the three-way pipe connector, the oil supply end of the three-way pipe connector, the oil return end of the three-way pipe connector; the utility model is characterized in that: a check valve is arranged in the oil supply end pipe of the three-way pipe connector, a check valve is arranged in the oil return end pipe of the three-way pipe connector. The utility model has the function of keeping pressure by arranging the a check valve in the oil supply end pipe of the three-way pipe connector when the electric burning pump stopped, and by arranging the a check valve in the oil return end pipe of the three-way pipe connector when the electric burning pump started. The utility model solves the problem of keeping system pressure on the oil supply pipe when the oil return pipeline is arranged through three-way pipe connector.
Description
Technical field
The utility model relates to a kind of automobile, motorcycle of being used for, with the device of fuel from fuel tank supply engine, and especially a kind of vehicle oil supplying device three-way union that is installed in the fuel tank.
Background technique
When running into oil feeding device for vehicle and not having conventional return line, set up a return line by on oil feed line, being provided with when three-way union can keep oil feed line, the fuel oil in the fuel tank is imported in the oil-storing barrel by the jet pump that the oil return in the return line of setting up drives on the oil-storing barrel.
But, when electric fuel punp quits work, originally can reach the pressurize effect by the one-way valve in the electric fuel punp, system pressure can descend by return tube fast through the oil revolving end of three-way union now.Simultaneously, the start up period of electric fuel punp, because the existence of return line, system pressure is difficult to set up fast, keeps the problem of system pressure to need to solve with regard to having produced one like this.
Summary of the invention
Goal of the invention of the present utility model provides the three-way union of a kind of vehicle oil supplying device, to overcome the deficiency that prior art exists.
Goal of the invention of the present utility model can realize by the following technical solutions:
The three-way union of a kind of vehicle oil supplying device comprises the oil inlet end of three-way union, the fuel feeding end of three-way union, the oil revolving end of three-way union, it is characterized in that: settled an one-way valve in the pipe of the fuel feeding end of described three-way union.
Settled an one-way valve in the pipe of the oil revolving end of described three-way union.
The utility model vehicle oil supplying device, makes when electric fuel punp quits work owing to settled an one-way valve in the pipe of fuel feeding end with three-way union, can stop system pressure to descend by return tube through the oil revolving end of three-way union by this one-way valve.Owing to settled an one-way valve in the pipe of oil revolving end, when making the electric fuel oil pump startup, system pressure can set up system pressure by the pretightening force pressurize of one-way valve upper spring fast.
Adopt above technological scheme, the utility model keeps the problem of system pressure when having solved on fuel supply line and to have set up return line separately by three-way union.
Description of drawings
Fig. 1 is the structural profile schematic representation of the utility model vehicle oil supplying device with three-way union;
Fig. 2 is the decomposition texture schematic representation of the utility model oil feeding device for vehicle;
Fig. 3 is the inner decomposition texture schematic representation of the oil-storing barrel of the utility model oil feeding device for vehicle.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3, oil-storing barrel 5 is provided with oil-storing barrel cover plate 6, and oil-storing barrel cover plate 6 is provided with three-way union 1.Electric fuel punp 7 is in oil-storing barrel 5, and the fuel feeding end 71 of electric fuel punp 7 connects the oil inlet end 11 of three-way union 1, and the fuel feeding end 12 of three-way union 1 links to each other with fuel supply line 3 by connector 4, and the oil revolving end 13 of three-way union 1 links to each other with return tube 2.
Fuel oil is from electric fuel punp 7 outputs, through three-way union 1.The part fuel oil is by fuel feeding end 12 input fuel supply lines 3 normal fuel injections of three-way union 1.Another part fuel oil is by the oil revolving end 13 input return tubes 2 of three-way union 1.
An one-way valve 15 has been settled in three-way union 1 in the pipe of fuel feeding end 12, an one-way valve 14 has been settled in three-way union 1 in the pipe of oil revolving end 13.
When electric fuel punp 7 quits work, can stop system pressure to descend by return tube 2 by one-way valve 15 through the oil revolving end 13 of three-way union 1.When electric fuel punp 7 started, system pressure can set up system pressure by the pretightening force pressurize of one-way valve 14 upper springs 141 fast.Take above technological scheme, the utility model keeps the problem of system pressure when having solved on fuel supply line and to have set up return line separately by three-way union.
Claims (2)
1, a kind of vehicle oil supplying device three-way union comprises the oil inlet end of three-way union, the fuel feeding end of three-way union, the oil revolving end of three-way union, it is characterized in that: settled an one-way valve in the pipe of the fuel feeding end of described three-way union.
2, vehicle oil supplying device according to claim 1 three-way union is characterized in that: settled an one-way valve in the pipe of the oil revolving end of described three-way union.
