Oil tank breather.
In order to further be illustrated more clearly that the technical solution of the application, now by the work of the oil tank breather of the application
Principle is described as follows:
When the expiration of the oil tank breather of the application, oil gas is filtered by exhalation passages and is discharged: snorkel 180 --- and it is unidirectional
Collect --- oil gas coalescing element 130 --- venthole 122 on the valve body 121 of the air passage one-way valve 120 --- respirator of oil funnel 110
The exhaust outlet being arranged on upper lid --- discharge.By upper, oil gas carries out the filtering and aggregation of oil gas, quilt by oil gas coalescing element 130
Filtered oil gas passes through the venthole 122 (diaphragm 123 is opened under stream pressure effect when expiration) of air passage one-way valve valve, and
The further exhaust outlet discharge by being arranged on lid on respirator.Wherein, the bottom of the oil gas coalescing element 130 is provided with one
From top to bottom, the point 132 for gradually tilting from radial outside towards radially inner side and assembling to centre.Pass through above-mentioned setting
It advantageously allows the oil droplet after being assembled to flow down along the point 132, and is flowed back into fuel tank by snorkel 180, it is real
Now to the recycling of oil droplet.
When the oil tank breather air-breathing of the application, oil gas is filtered by air intake passage and is sucked: air intake passage are as follows: air inlet
191 --- to filter out the second filter material of steam entrained by sucking air --- by 180 outside wall surface of snorkel, ventilator housing
In the cavity that 190 inner walls, first support 151, second support 171 surround jointly and wherein sucking air to be dried
Through-hole 113 is (at this time for the third filter material --- to filter out the first filter material of solid particle entrained by sucking air --- of processing
Funnel membrane 116 opened under the action of stream pressure so that through-hole 113 open) --- unidirectionally collect oil funnel
110 --- snorkel 180 --- fuel tanks.By upper, by the second above-mentioned filter material, third filter material, the first filter material successively to air
It is filtered, filtered air passes through through-hole 113 again and enters unidirectional collection oil funnel 110 later, then snorkel 180 enters oil
Case.
As shown in Fig. 5,7, above-mentioned exhalation passages and air intake passage can also be simplified shown as respectively:
--- expiration chamber b --- exhaust outlet --- discharge of exhalation passages: channel a；
Air intake passage: air inlet --- air-breathing chamber c --- --- expiration chamber b --- channel a --- fuel tank of through-hole 113
In conclusion funnel membrane 116, which is close to the through-hole 113, makes its closing, when exhaling so as to avoid oil
Gas enters air intake passage and pollutes air filter therein；In air-breathing, by the funnel under the action of stream pressure
Membrane 116 opens, so that being entered in unidirectional collection oil funnel 110 by filtered air by through-hole 113, then by logical
Tracheae 180 enters in fuel tank, and by upper, the exhalation passages and air intake passage of the application are separated, and avoids the oil gas of reflux to sky
Gas filters the pollution of filter material, and the oil gas of reflux is avoided to spill into external environment and pollute air.The arrangement achieves both
Effectively oil gas can be filtered, and can effectively filtered the air.

Struggle against neck --- fuel tank.By upper, when exhaling, under the pressure of air-flow, exhaust air passage one-way valve is opened, air inlet air passage one-way valve
It closes, enters air intake passage so as to avoid oil gas and pollute air filtration filter material therein；In air-breathing, in the pressure of air-flow
Under, air inlet air passage one-way valve is opened, and exhaust air passage one-way valve is closed, so that being entered unidirectionally by filtered air by through-hole
Collect in oil funnel, then entered in fuel tank by unidirectional oil-collecting filler neck part, flows through the outer of Accumulation of Hydrocarbon knot part in the air of sucking
It can also be conducive to for oil gas coalescing element coalescence oil droplet band being back in fuel tank when the conical surface, by upper, the application will by above structure
The exhalation passages and air intake passage of respirator separate, and avoid pollution of the oil gas of reflux to air filtration filter material, and avoid
The oil gas of reflux spills into external environment and pollutes air.The arrangement achieves can either be effectively filtered to oil gas,
It can effectively filter the air again.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
