Description

Suction tude plug-in type Oil-gas Separation air-strainer

One, technical field:

The utility model relates to a kind of air-strainer, especially motorcycle suction tude plug-in type Oil-gas Separation air-strainer.

Two, background technique:

The effect of air cleaner used on motorcycles is that the Carburetor that will send into motor after filtering from extraneous inhaled air mixes with gasoline, to guarantee the proper functioning of motor.At present, air cleaner for motorcycle mainly is made up of filter case, suction tude, steam outlet pipe and element kit, suction tude, steam outlet pipe all directly are welded on the housing, and steam outlet pipe directly links to each other with Carburetor by pipeline, and these all are unfavorable for the normal air feed of Carburetor.In addition, the waste gas of crankshaft box of motorcycle engine directly discharging advances in the atmosphere, has polluted environment, is unfavorable for environmental protection.

Three, summary of the invention:

The purpose of this utility model provides a kind of suction tude plug-in type Oil-gas Separation air-strainer, and solving existing air cleaner used on motorcycles can not be stably to the Carburetor air feed, and the waste gas of crankcase directly discharging advances in the atmosphere, thereby pollutes problem of environment.

The technical solution of the utility model is: it comprises housing, lid, suction tude, steam outlet pipe and element kit, wherein element kit will be divided into left and right sides chamber by the cavity that housing and lid form, left chamber links to each other with suction tude, right chamber links to each other with steam outlet pipe, it is characterized in that: A. is provided with the Oil-gas Separation chamber in right chamber, opening of Oil-gas Separation chamber links to each other with the valve on the housing, another opening is in right chamber, and window is installed thereon, have aperture on the window, film is arranged above the window, and sebific duct one end is connected on the film, and the other end passes window and carries out spacing to film; B. suction tude is inserted housing and is installed on the housing by the ring-like chute on it.

Valve on the utility model middle shell links to each other with the outlet pipe of engine crankcase, have aperture on the window, window and on film form a check valve, when the engine and carburetor air inlet, pressure in the right chamber descends rapidly, film is upwards heaved, right chamber communicates by the aperture on the window with the Oil-gas Separation chamber, waste gas in the engine crankcase enters right chamber by the Oil-gas Separation chamber, enter in the Carburetor again, greasy dirt wherein is then most of is isolated by film, and this not only makes air-strainer also avoided directly discharging the befouling environment that causes in the atmosphere because of the waste gas of crankcase stably to the Carburetor air feed.Suction tude is fixed on the housing by inserting chute, and the cross-section area of suction tude is remained in the parameters needed scope, has reduced intake resistance, thereby has guaranteed stable air inflow.

The utility model has the advantages that: to the good stability of Carburetor air feed, the waste gas of motorcycle (crankcase) does not discharge in the atmosphere, has avoided befouling environment, and simple in structure, easy to install.

Five, embodiment:

Please see Figure 1 to Fig. 6: the utility model is mainly by housing 1, lid 2, suction tude 3, steam outlet pipe 4 and element kit 5 are formed, wherein element kit 5 will be divided into left and right sides chamber 6 by the cavity that housing 1 and lid 2 form, 7, left chamber 6 links to each other with suction tude 3, right chamber 7 links to each other with steam outlet pipe 4, it is characterized in that: A. is provided with Oil-gas Separation chamber 8 in right chamber 7, opening of Oil-gas Separation chamber 8 links to each other with the valve 9 on the housing 1, another opening is in right chamber 7, and window 10 is installed thereon, have aperture 11 on the window 10, film 12 is arranged above the window 10, sebific duct 13 1 ends are connected on the film 12, and the other end passes 10 pairs of films of window 12 and carries out spacing; B. suction tude 3 is inserted housing 1 and is installed on the housing 1 by the ring-like chute 21 on it.

As can be seen from Figure 2: Oil-gas Separation chamber 8 in a tubular form, the opening that links to each other with valve 9 on the Oil-gas Separation chamber 8 is a radial opening.The shaft axis that is Oil-gas Separation chamber 8 is vertical with the shaft axis of valve 9, thereby can play buffer function to the waste gas that enters Oil-gas Separation chamber 8 from crankcase.

As can be seen from Figure 5: housing 1 and lid 2 " U " type annular groove 14,15 dislocation lap joints by in opposite directions have seal ring 16 in " U " type annular groove 14 together.Can avoid dust to enter better, and profile be more attractive in appearance.

As can be seen from Figure 4: the outer end of valve 9 is provided with cone boss 17, and cone boss 17 ends of valve 9 are fastened in the end of spring collar 19 with gum cover joint 18, and the other end of gum cover joint 18 seals with plug 20.

During use, steam outlet pipe 4 is linked to each other with the suction port of engine and carburetor of motorcycle, take off plug 20, gum cover joint 18 is linked to each other with the relief opening of crankcase, and tighten with spring collar 19.When the engine and carburetor air inlet, pressure in the right chamber 7 descends rapidly, film 12 is upwards heaved, right chamber 7 communicates with the aperture 11 of Oil-gas Separation chamber 8 by window 10, waste gas in the engine crankcase enters right chamber 7 by Oil-gas Separation chamber 8, enter in the Carburetor, greasy dirt wherein is then most of is isolated by film 12 again; When engine and carburetor stopped air inlet, the pressure in the right chamber 7 raise, and film 12 is depressed and is close on the window 10, thereby closes the aperture 11 on the window 10, and the waste gas in the engine crankcase can not enter right chamber 7 by Oil-gas Separation chamber 8.So repeatedly, this not only makes air-strainer also avoided directly discharging the befouling environment that causes in the atmosphere because of the waste gas of crankcase stably to the Carburetor air feed.
