Description
Technical field
The invention relates to a kind of engine and carburetor oil gas circulation means, particularly a kind of motor can 360 degree of engine and carburetor oil gas circulation meanss overturn.
Background technique
In order to make to start function normally to use under the various operating modes of comprehensive upset, motor adopts diaphragm carburetor, and its fuel oil service route is: fuel tank → fuel tap → Carburetor → hand primer → fuel tank.During work, open fuel tap.Diaphragm carburetor obtains pulsating vacuum pressure from the negative pressure mouth of engine air inlet tube, drives the negative pressure pump of self, fuel oil is extracted out endlessly from fuel tank, is transported to the shoe cream room of Carburetor.
Because the driving of Carburetor negative pressure pump is from motor, thus motor work first and start backward time, can because Carburetor shoe cream room in do not have fuel oil or fuel oil fewer, cause motor to start.At this moment, by pressing the oiling bubble of hand primer, drive to manually, the air in Carburetor shoe cream room and oil gas are extracted out and send fuel tank back to, fresh liquid fuel is full of Carburetor shoe cream room, thus completes the starting of motor.
But there is following problem at work in above-mentioned diaphragm carburetor oil gas circulation means: during upset work comprehensive with motor due to diaphragm carburetor, namely motor is toppled over or cylinder head works downwards, for reducing discharge vaporization and avoiding fuel oil to reveal, diaphragm carburetor does not design open to atmosphere relief opening.During engine operation, heat is passed to Carburetor by tracheae, causes Carburetor temperature to raise, and in shoe cream room, gasification of fuel oil produces " bubble ".Now fuel oil is mixed to form mixed gas with gaseous form and air, and the generation of bubble will make lean out, thus affects the work of motor, causes motor cutoff, even disorderly closedown.For this reason, many manufacturers and knowledgeable people have carried out R and D, but not yet have comparatively ideal product to emerge so far.
Summary of the invention
For overcoming existing Carburetor oil gas circulation means above shortcomings, the object of the invention be to provide a kind of simple and reasonable, working stability reliable, operate steadily, good energy-conserving effect, long service life can 360 degree overturn engine and carburetor oil gas circulation meanss.
The invention solves the technological scheme that its technical problem adopts, it comprises fuel tank, fuel tap, Carburetor, hand primer, fuel tank oil outlet is connected with switch filler opening, switch oil outlet is connected with Carburetor filler opening, Carburetor oil outlet is connected with hand primer filler opening, negative pressure pump is connected with between described hand primer and fuel tank, negative pressure pump comprises the pump housing, Returnning spring, diaphragm, diaphragm and Returnning spring are arranged in the pump housing, diaphragm is divided into negative cavity and oil pumping chamber pump housing inner chamber, negative cavity is provided with the import of negative pressure pump negative pressure, oil pumping chamber is provided with negative pressure pump filler opening and negative pressure pump oil outlet, negative pressure pump filler opening is provided with filler opening one-way valve, negative pressure pump oil outlet is provided with oil outlet one-way valve, hand primer oil outlet is connected with negative pressure pump filler opening, negative pressure pump oil outlet is connected with tank drainback mouth, the import of negative pressure pump negative pressure is connected with the negative pressure mouth at engine air inlet tube place, filler opening one-way valve opens, oil outlet closed check valve during negative pressure pump work, filler opening closed check valve, oil outlet one-way valve opens during negative pressure air pump inoperative.
The further scheme of the invention, described hand primer comprises valve seat, rubber one way valve, oiling bubble, rubber one way valve is made up of seal closure and spool disjunctor, valve seat is provided with the oil gun filler opening and oil gun oil outlet that are connected with valve pocket, oiling bubble is fixedly connected with valve seat, seal closure to be arranged in oiling bubble and to fit with valve seat and form inner cavity, inner cavity is communicated with valve pocket by aperture, spool is sealed and matched through valve pocket and oil gun oil outlet, and oiling bubble cavity volume is communicated with oil gun oil outlet by center spool hole.
The further scheme of the invention, described Carburetor is diaphragm carburetor.
After adopting said structure, compared with prior art have the following advantages and effect.
One is owing to being connected negative pressure pump between hand primer with fuel tank, negative pressure pump filler opening is provided with filler opening one-way valve, negative pressure pump oil outlet is provided with oil outlet one-way valve, the import of negative pressure pump negative pressure connects with the negative pressure mouth at engine air inlet tube place, pulsating negative pressure is produced during engine operation, when negative pressure produces, suction is produced and compression reseting spring to diaphragm, the oil pumping chamber of the pump housing produces negative pressure, filler opening one-way valve opens, oil outlet closed check valve, to make in Carburetor shoe cream room excess fuel or fuel mixture manually oil gun be extracted in the oil pumping chamber of the pump housing; After negative pressure disappears, Returnning spring pushing tow diaphragm, filler opening closed check valve, oil outlet one-way valve opens, sends the excess fuel in pump housing oil pumping chamber or fuel mixture back to fuel tank, thus reaches the object of oil gas automatic cycle.Two be due to motor start working after continuously can provide pulsating negative pressure, therefore negative pressure pump can keep long-term, stable work, fuel oil unnecessary in Carburetor or fuel mixture are extracted out endlessly sends fuel tank back to, make motor also can be long-term in unmanned environment, stable work, simultaneously, the circulation of fuel flow is defined while fuel oil unnecessary in Carburetor or fuel mixture are drawn out of, fuel oil absorbs heat through Carburetor from Carburetor, cool Carburetor, further suppress fuel oil to gasify in Carburetor shoe cream room, make motor also can the work of continous-stable under the high temperature of 40 ° of C.Three is improve hand primer, makes hand primer no longer independently have the function of manual pump oil, and hand primer can only coordinate negative pressure pump to realize the work of pump oil.
