Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1, Fig. 2 have clearly reflected the structure of one electromagnetic valve type vacuum oil-cutting device.As seen from the figure, at the opposite end of solenoid valve needle-valve one diaphragm 15 is housed, one end of switch plate 8 is fixed on the electrode 16 of solenoid valve 1, the outside of diaphragm 15 is fixed with an end cap, have axial bore on the end cap, spring 14 is contained in the ending cover hole, and ending cover hole communicates with air flue 2, and the another port of air flue 2 is positioned at the closure below.
As seen from Figure 3, split electromagnetic valve type vacuum oil-cutting device is vacuum switch 6 of polyphone in the circuit of solenoid valve.Fig. 4 is the concrete structure of vacuum switch 6, mainly comprise switch body 17, end cap 18, electrode 16, switch plate 8, diaphragm 15 and spring 14, electrode 16 is loaded in the switch body 17, one end of switch plate 8 is fixedly connected on the lateral electrode 16, the other end and opposite side electrode 16 movable contacts, diaphragm 15 is equipped with in the outside of switch plate 8, and spring 14 and end cap 18 are equipped with in diaphragm 15 outsides, have an axial bore on the end cap 18, this hole and vacuum way connect.
The working procedure of above-mentioned vacuum oil-cutting device is such, and when the motor proper functioning, degree of vacuum is less in the suction tude, and the switch plate 8 in the vacuum switch 6 is connected with solenoid valve 1 electrode, and solenoid valve 1 is opened, and Carburetor idle fuel way 3 is unimpeded, the Carburetor proper functioning; When automobile downhill or brake, be that the driver is when lifting accelerator pedal, carburetor throttle 7 is closed, the interior degree of vacuum of suction tude is increased suddenly, switch plate 8 in the vacuum switch 6 disconnects with solenoid valve 1 electrode, and solenoid valve 1 closure makes Carburetor idle fuel way 3 by fuel feeding, though this moment, motor still turned round in high speed or middling speed under action of inertia, the fuel feeding of Carburetor has stopped.When rotating speed drops to 600～700r/min when following, degree of vacuum reduces, switch plate 8 closures on the vacuum switch 6, and solenoid valve 1 is in time opened, and makes idle fuel way 3 recover unimpeded, guarantees the engine idle proper functioning.
Fig. 5 is the structure of mechanical type vacuum oil-cutting device, and this device is made up of air flue 2, piston 9, spring 10 and grease interceptor.A piston cylinder is equipped with in the side of idle fuel way top on the carbureter body; Alive cold 9 are divided into piston crown and piston rod two-part, piston crown is positioned at piston cylinder, and piston head is relative with gas port, and the another port of air flue 8 is positioned at closure 7 belows, upper cover of piston rod has spring 10, is fixing the location backing pin perpendicular to piston rod near the rod end.Grease interceptor is made up of little push rod 11, steel ball 12 and spring 13, and little push rod 11 is loaded on the rod end of piston rod, and the other end of little push rod 11 is equipped with steel ball 12, and spring 13 is equipped with in the below of steel ball 12.As seen from Figure 5, piston rod, little push rod 11, steel ball 12 and spring 13 all are positioned at idle fuel way 3.
The working procedure of above-mentioned mechanical type vacuum oil-cutting device is as follows.
When the motor proper functioning, degree of vacuum is less in the suction tude, and piston 9 promotes little push rod 11 grease interceptor steel ball 12 is depressed under the effect of spring 10, and idle fuel way 3 is unimpeded, the Carburetor normal fuel injection.When closure 7 is closed, when degree of vacuum increased suddenly in the suction tude, piston 9 was just picked up, piston rod and 11 disengagings of little push rod, and steel ball 12 is pushed away on the spring 13, and the idle fuel way filler opening is closed, and makes idle fuel way end fuel feeding.When rotating speed drops to 600～700r/min when following, the degree of vacuum of piston 9 tops reduces, suction weakens, move down at spring 10 effect lower pistons 9, under the effect of piston rod, little push rod 11 is depressed, steel ball 2 moves down, the filler opening of idle fuel way 3 is opened, and oil duct is unimpeded, guarantees the normal fuel injection of engine idle.
