Abstract
The utility model relates to equipment for conveying liquid fuel from a storage vessel to a jet device of a carburetor, particularly an automatic oil supply controlling oil-saving device for an automobile. The utility model has the structural characteristics that one end of a shell is provided with a main oil supply passage, and an oil dividing passage and a by-pass oil passage which are communicated with the main oil supply passage are arranged in the other end of the shell. A valve ball and a valve ball spring are arranged in the by-pass oil passage, are adjusted by adjusting screws, and are sealed and fixed by a closed welding body; an oil return connector which is communicated with the by-pass oil passage is vertically connected to the shell corresponding to the valve ball. The utility model has the characteristics of simple structure, convenient processing and installation, strong leakage resistance and stability, obvious oil-saving effect, obvious performance of vapor lock resistance, etc.
Description
The utility model relate to a kind of liquid fuel from storage container the conveying equipment system to the Carburetor injection apparatus, especially a kind of automatic control vehicle fuel feeding fuel economizer.
Modern gasoline class automobile or internal-combustion engine extensively adopt the Mechanical Driven diaphragm gasoline pump to come fueling at present, because itself structure limits, can not adapt to automobile needs to fuel delivery and oil pressure under various complex working conditions, cause oil consumption excessive, befouling environment and generation problems such as " vapour locks " takes place.A kind of " automobile voltage stabilizing circulate anti-vapour lock fuel economizer " disclosed among the Chinese patent CN87207608U, its structure characteristic is the return line that a straight-through fuel tank is drawn at Carburetor fuel inlet fitting place in former oil feed line, its recirculating oil quantity is then by the unidirectional valve ball that is arranged in the bypass of Carburetor fuel inlet fitting, the valve ball spring is adjusted the control valves that element constituted such as screw and locking big nut and is controlled.This fuel economizer has certain effect aspect the above-mentioned shortcoming overcoming, but because the back leakage connection of its loop configuration is by locking big nut and front and back pad compression fit, is easy to generate the fuel oil infiltration leakage during the higher and fitting surface assembling of processing request; In addition, the pressure of its unidirectional valve ball and valve ball spring is regulated by adjusting screw and nut, and they can get loose, lack of proper care because of the variation and the mechanical shock of pressure, and oil-saving effect and anti-vapour lock performance can be under some influence.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, provide a kind of structure more simple, processing and installation are more convenient, and the anti-leakage performance is good, working stability is stronger, thereby oil-saving effect and the more obvious automatic control vehicle fuel feeding of anti-vapour lock performance fuel economizer.
The purpose of this utility model can reach by adopting following technical proposal, on the basis of CN87207608U patented technology scheme, back leakage connection directly is being connected with screw threads for fastening with housing corresponding to the valve ball position, so that enter back leakage connection surveying flow oil sump tank immediately after making oil return back down unidirectional valve ball with certain pressure.The pressure of unidirectional valve ball and valve ball spring is adjusted and sealed fastening to adjust screw and sealing melting welding body, get loose, lack of proper care because of vibrations preventing.
The utility model is compared with original technology, because fit form changes and has reduced the part composition, so that it has structure is more simple, processing and install more convenient, the anti-leakage performance is good, working stability is stronger, thus oil-saving effect and gas-tight resistive can be more obvious etc. characteristics.
Accompanying drawing 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.Automatic control fuel feeding fuel economizer is connected with the Carburetor oil inlet hole with pad 4, is connected with fuel inlet fitting 2 at an end of garden column type housing 1 with Vertical direction, and it communicates with main oil gallery 5 in the housing 1 through oil inlet hole 3.Be provided with the branch oil duct 6 and the bypass oil duct 7 that communicate with main oil gallery 5 in the housing 1 of the other end, be provided with valve ball 8 and valve ball spring 9 in the bypass oil duct 7, they are by adjusting screw 10 and sealing melting welding body 11 and regulate and sealing, the back leakage connection 14 that is threaded with Vertical direction is arranged on the housing 1 corresponding to valve ball 8 places, and it communicates through spill port 13 and bypass oil duct 7.The locking protection nut 12 that the far-end of housing 1 is provided with and is threaded will be adjusted screw 10 and be closed in wherein with sealing melting welding body 11 again.
The utility model working procedure is stated as follows: automatic control fuel feeding fuel economizer is placed in Carburetor oil-feed screw place with pad 4, and under normal conditions, through the fuel inlet fitting 2 of fuel economizer, oil inlet hole 3 flows into main oil gallery 5 to fuel oil earlier, and it is indoor to enter carburettor float again.Once Carburetor has satisfied the motor proper functioning with behind the oil, float is elevated to certain position just forces the triangle needle-valve to be closed, this moment, fuel oil can not enter in the float chamber and oil pressure raises gradually, when elevated pressure has surpassed the elastic force of valve ball spring 9 of fuel economizer, oil stream just backs down the unidirectional valve ball 8 in the branch oil duct 6, and flow to bypass oil duct 7, directly flow in the fuel tank and go through spill port 13, back leakage connection 14, return tube again.As increasing because of engine oil, the float chamber pasta reduces the triangle needle-valve and opens naturally, oil pressure in the main oil gallery 5 descends, and the elastic force of the valve ball spring 9 in the bypass oil duct 7 is greater than the oil pressure of main oil gallery 5, valve ball 8 just trend is closed, this moment, fuel feeding oil stream was just under action of pressure, all or part of Carburetor that flows to; In entire work process, fuel economizer automatically control distributes fuel feeding to two ends evenly---and supply engine is with oily or unnecessary fuel oil is flow back to fuel tank recycle.Fuel economizer for the fuel delivery that guarantees the automatic control fuel feeding and oil pressure in optimum value, on the special detection platform, debug in advance: as long as suitable, the adjustment screw 10 that is provided with in the counterclockwise rotation bypass oil duct 7, it just can be advanced and retreat and regulate the length and the elastic force of valve ball spring 9, the degree of closing of control valve ball 8; When debugging optimum oil feeding and oil pressure operation point, seal fastening with sealing melting welding body 11 and locking protection nut 12 again.
