[embodiment]
Below, use accompanying drawing and utilize embodiment to specifically describe the utility model.
(1) structure of oil mist separator
The oil mist separator 1 of the present embodiment is by making to circulate the contained vaporific oily oil mist separator of separate blow-by gas to the gas leakage of the crankcase internal leakage of internal-combustion engine.As shown in Figure 1, oil mist separator 1 comprises for the gas flow path 3 of gas leakage circulation and the relief valve 5 that is configured in this gas flow path 3 and opens and closes under the effect of the pressure of gas leakage.
Gas introduction part 9 and gas discharge section 11 are formed at respectively two ends of separator main body 7.Space in the crankcase of gas introduction part 9 and not shown internal-combustion engine is connected, and the gas leakage leaking in crankcase is imported in separator main body 7.Gas discharge section 11 is connected with the gas handling system of not shown internal-combustion engine, will import in firing chamber together with air-breathing from the gas leakage of separator main body 7 interior discharges.
The mode that oil discharge portion 13 is extended downwards with the diapire from separator main body 7 forms tubular, and in the bottom of oily discharge portion 13, is formed with the little hole of the tubular part of sectional area ratio.Thus, in oily discharge portion 13, accumulate and have the oil that is split into its inside.In addition, if the oil in oily discharge portion 13 is accumulated predetermined height, this oil overcomes the pressure of the gas leakage in gas flow path 3 and discharges to outside.The oil of discharging in addition, returns to the food tray of crankcase below.
As shown in Figure 2, relief valve 5 has wall portion 15 and valve body 17.Wall portion 15 forms extend towards interior side direction from the inwall of separator main body 7 tabular, is configured to separate gas flow path 3, and has the opening portion 19 that can circulate for gas leakage.Opening portion 19 is to be formed with the mode opening in a hole running through wall portion 15.Valve body 17 is set to from the opening portion 19 of the downstream side covering wall portion 15 of gas flow path 3.Valve body 17 is biased and shutoff opening portion 19 to the direction of wall portion 15, and the downstream side to gas flow path 3 is pressed and opens opening portion 19 when the pressure ratio authorized pressure leaking gas is high.
In valve body 17, at the mask of a side relative to opening portion 19, there is filter element 21.Filter cell 21 adopts the roughly nonwovens of circular plate shape.In addition, valve body 17 has from the supporting mass 23 of downstream side supporting filter device element 21.As shown in Figure 3, supporting mass 23 be configured to supporting filter device element 21 part hole enlargement general cylindrical shape shape.In addition, face and peripheral wall surfaces that face this supporting mass 23 and downstream side filter cell 21 connects form respectively clathrate, and gas leakage can be circulated in the gap of this grid (being illustrated as through hole of the present utility model).
In the present embodiment, valve body 17 is by helical spring 25 application of forces.Thus, as shown in Figure 2, valve body 17 is pressed against wall portion 15 compacted state shutoff opening portion 19 with filter cell 21.Helical spring 25 is configured between the hole enlargement part and guiding elements 27 of supporting mass 23 of valve body 17, and this guiding elements 27 supports supporting mass 23 in the mode of sliding freely and along operative orientation guiding valve body 17.
(2) effect of oil mist separator
The effect of the oil mist separator 1 of said structure then, is described.The gas leakage leaking in crankcase is imported into oil mist separator 1 separated fuel-displaced.In detail, as shown in Figure 1, gas leakage imports in separator main body 7 from gas introduction part 9 at first.The gas leakage importing arrives relief valve 5, and via the opening portion 19 of wall portion 15, collides the filter cell 21 of valve bodies 17.Because the direction of valve body 17 to wall portion 15 is biased and shutoff opening portion 19, the therefore logical filter cell 21 downstream circulations of the gas leakage after collision.Now, the contained vaporific oil that leaks gas is collected by filter element 21, separated fuel-displaced.Then, by the gas leakage after filter cell 21, from gas discharge section 11, discharge.And isolated oil is fallen the diapire of separator main body 7, from oily discharge portion 13, discharge.
In addition, when producing the obstruction etc. of filter cell and the pressure ratio authorized pressure of gas leakage when high, as shown in Figure 4, valve body 17 downstream side is pressed and opens opening portion 19.Thus, alleviate the pressure rise of the gas leakage in gas flow path 3.
Now, the filter cell 21 that the collision of the gas leakage by after opening portion 19 has retreated to the downstream side of opening portion 19.A part for the gas leakage of collision filter cell 21 with by filter cell 21 downstream, circulate in the same manner at ordinary times, and another part changes progress path and circulates by the gap downstream between wall portion 15 and valve body 17.Then, separated as conventionally by the gas leakage after filter cell 21, change progress path and passed through the gap between wall portion 15 and valve body 17 gas leakage inertia collide filter cell 21 and isolate its contained mist of oil.Like this, even the in the situation that of relief valve 5 work, also suitably carry out oil separation.
(3) embodiment's effect
According to above content, the oil mist separator 1 of the present embodiment comprises for the gas flow path 3 of gas leakage circulation and the relief valve 5 that is configured in gas flow path 3 and opens and closes under the effect of the pressure of gas leakage.Relief valve 5 has the valve body 17 that is configured to the wall portion 15 of separating gas flow path 3 and having opening portion 19 and covers opening portion 19 from the downstream side of gas flow path 3.Valve body 17 is biased and shutoff opening portion 19 to the direction of wall portion 15, and the pressure ratio authorized pressure of gas leakage when high downstream side be pressed and open opening portion 19.And, on the face of the side relative to opening portion 19 of valve body 17, there is filter cell 21.
According to this structure, at ordinary times, filter cell 21 is passed through in gas leakage, thereby guarantees sufficient oily separation function.In addition, in the situation that the pressure rise in gas flow path 3, relief valve 5 work, alleviate the pressure rise of the gas leakage in gas flow path 3.And this situation also can be guaranteed oily separation effect due to the filter cell 21 of the gas leakage collision valve body 17 by opening portion 19.Thereby oil mist separator 1 can alleviate the pressure rise of the gas leakage in gas flow path 3, and also can guarantee oily separation effect.
In addition, in the above-described embodiments, because filter cell 21 is supported from downstream side by the supporting mass 23 being formed with as the gap of the grid of the through hole for gas leakage circulation, the resistance in the time of therefore can suppressing gas leakage circulation, can suppress pressure rise.In addition, by filter cell 21, be supported body 23 supportings, thereby can suppress the distortion of filter cell 21.
