Abstract

The utility model relates to a by-pass air valve type idling oil saving device. The by-pass air valve type idling oil saving device is composed of an outer shell body, a by-pass air passage, and an air inlet valve. The air inlet valve is an outer closed type, and is provided with an electromagnetic type air valve controller. The by-pass air valve type idling oil saving device has simple structure and reliable performance. The by-pass air valve type idling oil saving device is suitable for gasoline engines with various types. Even if an operating mechanism fails, the normal work of an engine can not be influenced. The by-pass air valve type idling oil saving device especially solves the problem that the engine oil of the existing similar device upwards fleeing.

Description

By-pass air-valve idling economizer

The utility model relates to a kind of bypath air valve formula idling fuel economizer.

The idle speed fuel saved device of existing gasoline locomotive motor, generally have following severally, a kind of is to interrupt fuel feeding, is included in the Carburetor filler opening and installs valve additional, hangs float method etc., trapped fuel in the Carburetor is continued to draw because of the negative pressure that cylinder produces in the capital, and can impel machine oil to scurry into cylinder; Another kind of as the disclosed automobile downhill gasoline-saving device of CN2054833U, adopted the suction valve structure, solve foregoing problem with the degree of vacuum that changes in the cylinder body, this gasoline-saving device mainly is made up of air throttle and suction valve, its suction valve adopts the inner sealing formula, by a ball, the gentle valve pocket of spring constitutes, spring handle garden pearl outwards withstands on the air valve cover pore, stop the supply of long way mixed gas after closing air throttle when relying on idling, the garden pearl is opened in the mandatory suction of negative pressure that produces in the cylinder, and ambient air is entered in the cylinder, changes the interior mixed gas ratio of cylinder and achieves the goal, closing air throttle rear-bank rotor housing domestic demand certain negative pressure when its deficiency is idling could open the suction valve suction, if spring force is bigger, required negative pressure is also corresponding bigger, still might cause machine oil to scurry into cylinder, if spring force is too small, during the motor proper functioning, suction valve must cut out, and the negative pressure that is produced during cylinder operation still might be inhaled and driven air valve into, destroy mixed gas ratio in the cylinder body, influence the motor proper functioning.On the other hand, spring is the tired or damage of meeting after use a period of time, makes suction valve lose encapsulation, and motor just can't proper functioning.From general structure, this device can only be installed on the trunnion, thereby applicable surface is narrow, need do bigger change to some motor and could install.

The utility model is a kind of bypath air valve formula idling fuel economizer that proposes at the problems referred to above.

The utility model comprises frame, bypass air flue, suction valve, its characteristics are that said suction valve is an external closing type, form by air intake valve, assisted decompression valve, push rod and Returnning spring, suction valve is in the bypass air flue, the assisted decompression valve is in the outside of main valve, and an end of push rod is provided with the electromagnetic type air valve controller.

Compare with existing similar gasoline-saving device, the utlity model has following advantage: the one, adopted the external closing type valve, the sealing of valve relies on Returnning spring, the negative pressure that has formed when having utilized cylinder operation simultaneously, the possibility that valve is opened when having got rid of the cylinder proper functioning, even spring fatigue, damage or operating mechanism are malfunctioning, because the negative pressure that cylinder body work causes, air intake valve is closed all the time, can not influence the proper functioning of motor, the 2nd, opening of valve is to rely on magnet control, the air pressure of opening in the valve rear cylinder is almost identical with the external world, thereby can not draw the trapped fuel in the Carburetor, has also solved the problem that machine oil is scurried into cylinder, the 3rd, easy for installation flexibly, can be applicable to the motor car engine of various models.

Below in conjunction with accompanying drawing structure of the present utility model and user mode are elaborated.

Fig. 1 is an embodiment's of the utility model a structural representation.

The utility model comprises frame (5), bypass air flue (1), all there is adpting flange (4) at the two ends up and down of housing, opening by electromagnetic type controller (9) of suction valve controlled, suction valve is located in the bypass air flue, the outside of housing, by Returnning spring (10) suction valve is inwardly pressed to valve pore (6).Air intake valve is made up of main valve (3) and assisted decompression valve (2), and pressure loading valve directly is fixed on the push rod (4) in the outside of main valve, and main valve and stage clip are enclosed within on the push rod successively, and stage clip (7) is outwards pressed to pressure loading valve to main valve.

When the utility model is installed, can directly be connected between engine intake manifold and the Carburetor with adpting flange, also can be on intake manifold boring one aperture, an end is connected on the intake manifold with adpting flange, the other end covering palte seal.The bypass air flue is connected on the air Cleaner.Electromagnet can with the suction valve heteropleural, also can be in the bypass air flue of suction valve homonymy, circuit switch can link with gas pedal.

The utility model working state is as follows: when automobile enters idling mode, when the complete pine of throttle is lifted, the electromagnet action, at first open pressure loading valve, reduce degree of vacuum in the cylinder, then stage clip is pushed main valve open, and vaporizer is in fully by bypass condition and stops to supply with the mixed combustible gas body, the extraneous pure air of the then complete suction of motor, fuel consumption not, when driver is stepped on the throttle, the electromagnet outage is in Returnning spring and cylinder under the effect of vacuum power, air intake valve is closed, during by bypass, its float chamber and each oil duct all maintain fuel oil and work pasta, are in initial working state because of Carburetor, so moment that suction valve cuts out, cylinder recovers degree of vacuum at once, and Carburetor produces burning mixture thereupon, the beginning proper functioning.

Claims

1, a kind of bypath air valve formula idling fuel economizer, comprise frame, bypass air flue, suction valve, it is characterized in that said suction valve is an external closing type, form by air intake valve, assisted decompression valve, push rod and Returnning spring, suction valve is in the bypass air flue, the assisted decompression valve is in the outside of main valve, and an end of push rod is provided with the electromagnetic type air valve controller.
