Abstract

The utility model provides a throttle valve which belongs to the carbureter of the gasoline engine. A shutoff valve, an oil pumping container and a reversing valve totality are additionally arranged on the original carbureter of the gasoline engine. The valve is controlled through the pedal of a throttle door and linked through the piston and a spring in the oil pumping container and an electromagnet to pump and return oil. The throttle valve directly injects oil through the reversing valve totality in the process of returning oil. So the throttle valve reliably breaks oil thoroughly and does not leak oil, and the throttle valve quickly supplies oil. The oil saving effect of the utility model is obvious. When the automobile is driven specially at night, in a rainy day and in loading, the automobile does not fling the neutral position in general, so the oil saving effect of the throttle valve is more obvious.

Description

Throttle valve

The utility model belongs to petrol engine carburetor.

At present China's petrol engine vehicle is in the descending highway section, and the driver often gets rid of neutral, allows engine misses, and its main purpose is for fuel-economizing, and on homemade Carburetor, when closed throttle, vehicle is used descending and put into gear and slide, and occurs oil leakage phenomenon easily.Be exactly the method control of on the passage of float chamber fuel feeding, using the spindle switch, also be difficult to ensure the good result of long-term oil-break.

According to the used marine products of going up of EQ140, model is the Carburetor of EQH120-1, and the fuel-economizing principle is by a magnetic switch stifled disconnected idle fuel way (14) when the vehicle descending.This method is at the vehicle load descending, and engine speed increases, and Highway Conditions is bad, and under the situation such as Carburetor internal structure, equally also has oil leakage phenomenon, and oil-saving effect is 2～3 liters of per 100 km fuel-economizings, and oil-saving effect neither be very desirable.

The purpose of this utility model is the deficiency at prior art, it is thoroughly reliable to propose a kind of oil-break, oil-proof, fuel feeding is Oil Switch rapidly, this switch leaves the pedal of closure by pin, just can close oil supply system automatically, promptly in the place ahead of Carburetor triangular headed scribing cutter fuel feeding, oil interrupter switch (3) is installed, cut off the petrol pump fuel feeding, allow the piston in the float chamber below oil pumping container (11) produce suction movement simultaneously, the interior gasoline of whole float chamber is taken out light, allow the interior oily plane of container be lower than all oil ducts outlets of float chamber inner bottom part, just oil leakage phenomenon can not occur.

During unimpeded oil circuit, oil interrupter switch (3) is opened, allow triangular headed scribing cutter (2) recover original oil supply performance, meanwhile, the piston in the oil pumping container is done also oil motion under the effect of truncated cone spiral compression spring (10), in also oily process, use and go back oil pressure, have and pass through overall (23) the directly oil spout in trunnion of reversing switch controlledly, fuel feeding is rapid.

The utility model is achieved in that it totally reaches circuit control device by Carburetor, oil interrupter switch, oil pumping container, piston, screens, reversing switch and forms.On the basis of the original Carburetor of petrol engine, increase array apparatus down:, on the petrol pump fuel supply line, oil interrupter switch (3) is installed 1, in the place ahead of Carburetor triangular headed scribing cutter (2) fuel feeding; 2, oil pumping container (11) is housed below carburetor bowl; 3, reversing switch overall (23) is housed in float chamber.

The oil pumping container is a cylindrical shape, and the top is gone back oil duct (6) by the master and is communicated with float chamber (4), and the piston that circular clamping plate (7) and diaphragm (9) are formed is installed in the oil pumping container.Circular film (9) periphery is compressed by the flange of two-section about the oil pumping container, and with fixing around the screw edge, middle diaphragm is clamped by circular clamping plate (7) up and down.The below is fixed with piston linkage rod (8) in the middle of the piston, below piston, truncated cone spiral compression spring (10) is arranged on the circumference of linkage rod.

Main go back oil duct (6) directly in the float chamber, screens (5) laterally is housed, it can avoid piston also during oil, under the effect of oil column at air-flow of indoor formation, along balance tube (1) fuel feeding, can reduce oil column height to float chamber.

Reversing switch overall (23) is installed in the float chamber, a side of accelerating pump (16), and the bottom is on reversing switch linkage rod (17), and reversing switch linkage rod upper end is connected with accelerating pump linkage rod (15), and the top is with buffering Regulation spring (18).When closed throttle, guarantee that simultaneously straight tube (19) also is closed.Reversing switch totally is a cylindrical shape, axially in the middle of the circular hole taper oil duct is arranged up and down, the top of oil duct is communicated with straight tube (19), the below is gone back oilhole (24) and is communicated with float chamber by negative, and there is reverse double needle (22) centre of two taper oil ducts, and its two is a taper shape, the centre is cylindrical, the double-ended needle end of awl down has a straight-bar by the inferior pyramidal oil duct, and the straight-bar bottom is a round boss, mounting spring on the boss.The overall lateral aperture of reversing switch is gone back oil duct (6) and is communicated with leading by the negative oil duct (25) of going back.

When closure (13) when opening, reversing switch linkage rod (17) is under the drive of accelerating pump linkage rod (15), it is overall to break away from reversing switch, oppositely double-ended needle cuts out under the effect of spring from bearing and goes back the negative oilhole (24) of going back that oil duct leads to float chamber, the straight tube (19) that leads to trunnion (12) is opened directly oil spout in trunnion simultaneously.Its fuel delivery in trunnion depends on that the aperture situation of closure, injection time equal also oil beginning to the time that stops.Adopting this structure, is in order also to strive for that the time that fuel feeding quickens shortens in the oily process.

At negative oil duct (25) and the main jointing place installation one-way valve (27) of going back oil duct (6) gone back, this valve cuts out when pumping container do oil pumping action, and assurance is born to go back oily the existence in oil duct and the accelerating pump, and when loading greatly suddenly, fuel feeding is fast, and when going back oil, valve is freely opened.Negative go back oil duct above one-way valve (21) is housed, when the oil pumping container is done also oil action, in pipe, close under the oil pressure effect, no oil pressure is then unimpeded in float chamber.

Install with the float chamber intersection and adjust valve (26) at the main oil duct of going back, the gasoline flow velocity in the time of can adjusting oil pumping with oil also, the oil pressure requirement of assurance straight tube in a certain scope.

The power that oil pumping container inner carrier moves up and down by electromagnetic force, leans on the elastic force of truncated cone spiral compression spring during oil pumping when also oily.

Pumping and going back in the process of oil, be temporary electricity, after pistons work puts in place, with regard to mutual automatic outage.

Because of the fuel delivery scope of considering straight spray in control between the big load, so on circuit, be provided with main switch (32), allow Oil Switch under slow train or reverse travel situation, do not participate in work.

Electric switch (31) is located at the throttle wood clapper rear lower side, and when pin left, Oil Switch just cut off oil supply system, on the contrary unimpeded fuel feeding.

Before the piston oil pumping, switch disconnects on big coil (35) circuit, switch connection on small coil (29) circuit, but the circuit upper contact disconnects at big coil place.

The piston oil pumping is pushed switch (31) to top, cuts off small coil (29), connect big coil (35), whole big coil circuit is connected, electric current from positive source to switch, to big coil contact, to big coil, to power cathode, big iron core (36) moves downward under the electromagnetic force effect, by linkage rod and pressure spring, piston is pumped.After big iron core motion puts in place, just connected small coil contact (34), spring (28) just in time advances fore shaft (37) with little iron core (33) lock bolt at the same time.Because the motion of little iron core puts in place, just in time cuts off big coil contact (30) again.

Piston is oil also, the small coil circuit, except outside the Pass, remaining circuit is unimpeded, existing pushes switch to below, cuts off big coil at the switch place, and connects small coil, electric current is from positive source to switch, to small coil, to the small coil contact, to power cathode.Little iron core (33) moves right under the electromagnetic force effect, up to pulling out lock bolt, connect simultaneously big coil contact again, after pulling out lock bolt from fore shaft, piston and linkage rod are under the effect of truncated cone spiral compression spring (10), move upward and make also oil, simultaneously after linkage rod has just begun to move upward, and the small coil contact also is cut off circuit.

The utility model compared with the prior art owing to increased oil interrupter switch on former petrolic Carburetor, oil pumping container and reversing switch are overall.So it is thoroughly reliable, oil-proof that the utility model is a kind of oil-break, fuel feeding is Oil Switch rapidly.In the time need not refueling, leave the pedal of closure by pin, just can close oil supply system automatically, therefore easy to operate.From oil-saving effect, last marine products EQH120-1 type Carburetor, hundred kilometers can fuel-economizing 2～3 kilograms, and it only is the minimum fuel-economizing value of the utility model Oil Switch.

When the driving of night driving and rainy day, generally dare not get rid of neutral, so fuel consumption is big, oil-saving effect is just more obvious behind the employing Oil Switch.The load-carrying lorry does not generally get rid of neutral, particularly down long and steep when sloping, just more embodies the oil-saving effect of Oil Switch.
