Embodiment
Below in conjunction with the drawings and specific embodiments, technical solution of the present invention being described in detail, further to understand object of the present invention, scheme and effect, but is not the restriction as claims protection domain of the present invention.
Consult Fig. 2 to Fig. 3, the first embodiment's that Fig. 2 is Carburetor of the present invention partial sectional view, Fig. 3 is the E place enlarged view of Fig. 2.As shown in the figure, Carburetor of the present invention comprises Carburetor body 10, oilier 20 and one-way valve 30.Oilier 20 is connected on Carburetor body 10, and one-way valve 30 is connected on oilier 20.
Oilier 20 comprises oilier fitting seat 21, pump oil part 22, pump oil part retainer ring 23 and oilier spring 24.
Oilier fitting seat 21 is connected on Carburetor body 10.Carburetor body 10 includes inlet air pathway 11 and lower cover 12, and lower cover 12 has Zhu You district, and inlet air pathway 11He Zhuyou district is connected.
Oilier fitting seat 21 includes gas-entered passageway 211, and inlet air pathway 11 is connected with gas-entered passageway 211.
Pump oil part 22 has suction port 221, and wherein, suction port 221 is preferably arranged at the bottom of pump oil part 22.Pump oil part 22 is compressible, and it is example that pump oil part 22 of the present invention be take pump outermost layer of skin bowl, but not as limit.Pump oil part 22 is connected on oilier fitting seat 21 by pump oil part retainer ring 23, thereby forms Yi Rong gas chamber 25 between pump oil part 22 and oilier fitting seat 21, holds gas chamber 25 and is connected with gas-entered passageway 211.
Oilier fitting seat 21 also includes spring butting section 212, and oilier spring 24 is arranged at and holds in gas chamber 25, and oilier spring 24 one end compress the bottom of pump oil part 22, and the other end compresses the spring butting section 212 of oilier fitting seat 21.
Gas enters appearance gas chamber 25 from the suction port 221 of pump oil part 22, and by gas-entered passageway 211, enters the inlet air pathway 11 of Carburetor body 10, and then enters lower cover 12Zhu You district.
One-way valve 30 comprises one-way valve seat 31, spheroid 32 and check valve spring 33.Wherein, one-way valve seat 31, spheroid 32 and check valve spring 33 are set in turn in the gas-entered passageway 211 of Carburetor fitting seat 21 according to airintake direction.Wherein, airintake direction specifically refers to the direction that the suction port 221 of air from pump oil part 22 enters the lower cover 12Zhu You district of Carburetor body 10.So, the gas-entered passageway 211 of oilier 20 and the inlet air pathway 11 of Carburetor body 10 are controlled by one-way valve 30, and oilier 20 is to unilaterally connected between the lower cover 12Zhu You district of Carburetor body 10.
Wherein, gas-entered passageway 211 has stepped part 213, and check valve spring 33 one end compress spheroid 32, and the other end compresses stepped part 213.
Consult Fig. 4 and Fig. 5, the second embodiment's that Fig. 4 is Carburetor of the present invention partial sectional view, the F place enlarged view that Fig. 5 is Fig. 4.Inlet air pathway 11 is divided into the first inlet air pathway 111 and the second inlet air pathway 112.Wherein, the first inlet air pathway 111 is connected with gas-entered passageway 211, and the second inlet air pathway 112 is connected with lower cover 12Zhu You district.In the present embodiment, the one-way valve seat 31 of one-way valve 30, spheroid 32 and check valve spring 33 are set in turn in the first inlet air pathway 111 according to airintake direction.Wherein, the first inlet air pathway 111 has supporting portion 113, and check valve spring 33 one end compress spheroid 32, and the other end compresses supporting portion 113.
Consult Fig. 6 and Fig. 7, the 3rd embodiment's that Fig. 6 is Carburetor of the present invention partial sectional view, the G place enlarged view that Fig. 7 is Fig. 6.In the present embodiment, the one-way valve seat 31 of one-way valve 30, spheroid 32 and check valve spring 33 are set in turn in the second inlet air pathway 112 according to airintake direction.Wherein, the second inlet air pathway 112 has stepped part 114, and check valve spring 33 one end compress spheroid 32, and the other end compresses stepped part 114.
Below the working procedure of Carburetor and oilier thereof is introduced.When oilier 20 is not worked, one-way valve 30 is closed condition, and check valve spring 33 compresses spheroid 32, spheroid 32 is closely resisted against on the ventilating hole of one-way valve seat 31.During oilier work, extrusion pump oil part 22, oilier spring 24 shrinks, and the suction port 221 of air from pump oil part 22 enters to and holds gas chamber 25, and then promotes the spheroid 32 of one-way valve 30, and air enters Carburetor body 10 from the ventilating hole of one-way valve seat 31.When oilier 20 is not worked, stop extrusion pump oil part 22, check valve spring 33 returns closely cooperate spheroid 32 and one-way valve seat 31, the lower cover 12Zhu You district of Carburetor body 10 closes and is not communicated with because of one-way valve 30 with the appearance gas chamber 25 of oilier 20, thereby stops the gasoline in Zhu You district to enter the pump oil part 22 of oilier 20 from Carburetor body 10.
In addition, the material of the spheroid 32 of one-way valve 30 can be steel ball or the copper ball of metal species, can be also the baton round of non-metal kind, as long as intensity and hardness reach requirement of the present invention.
Certainly; the present invention also can have other various embodiments; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art are when making according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
