Description of the invention: [Technical field to which the invention pertains] A transition device for a gas vehicle, in particular, is used to be installed in a fuel suction port as provided therein, to filter fuel from which the fuel pump is sucked and sucked in. Improvement of the filter device. [Prior Art] The use of the bag, the locomotive, etc. Tit 〇2〇r^6026 makes ^ #二7 even if it usually ensures oil-water separation, but the pressure generated by the volume expansion of water in the cold zone forces the water to immerse the boundary: normal oil supply, therefore, effective prevention The flooding people are still persuading; ^ device.

(4) Listening to the inside _ with the fabric suction port (2) The filter system forms a single layer or a multi-layer structure; (3) and when it is a monolithic structure, it is integrated as a whole, if more filters of the 200835544 layer structure are formed Then, it will be ((=============================================================================================== The internal space forms a single-layer or multi-layer structure with the fuel suction port (2) filter system; (3) ΐίϊ is a filter body formed into a single-layer structure, and if it is formed into a plurality of corpses, at least One layer is composed of ()' with an average The hole control is a water-blocking layer under the pressure of 2〇#mu. In order to achieve the purpose of the above-mentioned problems, the fuel filter and device of the present invention have the following (1) ~ (4 = the structure of the moon - the invention (1):: face The reversing device, the bell-remaining, the wire in the fuel tank and the inlet portion 'to make the internal space of the filter body and the material suction port (2) filter system form a single layer or multi-layer structure; (3) and in the form of a single The filter body of the layer structure is formed as a whole, and at least one layer of the filter body of the layer structure is formed as follows: y (4) Under the water pressure of less than 15 (four) (kPa), the water blocking layer is not allowed to pass through the water. The filter device has a structure that can block the moisture from entering the inside of the filter body by utilizing the pressure acting on the filter body when the water in the fuel tank is frozen by the temperature, and setting the average mesh aperture of the filter body to 2〇= The following structure, and the relationship between the water-blocking layer of the structure in which the pressure of the filter body is allowed to pass water is set to be 45 kpa or more, so that the function of separating the oil-water separation is not necessary, and it is effective in use in cold regions and the like. Prevent moisture from being mixed into the fuel The water freezes the pressure generated and enters the fuel pump end. The water blocking layer of the filter of the 200835544 device is preferably composed of a contact angle with water and a resin material having a difference of fuel of 80 degrees or more. Even if the fuel t is mixed with water, the water blocking layer can be = giant to prevent water from invading the inside of the body. That is, by the composition of the water blocking resin material, the oil water efficiency can be ensured under various temperature conditions. The knife constitutes the outermost layer of the object such as a water blocking layer which is formed by the mesh fabric and is disposed on the inner side of the layer, such as a non-woven fabric, so that the water blocking layer is prevented from being directly contacted with the inner wall of the fuel tank or the like. The layer containing the water blocking layer composed of the non-woven fabric on the inner side of the outermost layer may have two or more layers, and the sound average pore diameter located inside the filter body may be smaller than the outer layer located on the outer side of the filter body. The average aperture 曰. In such a filtering device, the dust having a relatively large particle size can be captured by the non-woven layer on the outer side, and the dust having a smaller particle size can be captured by the non-woven layer located on the inner side of the scorpion body. Therefore, it is difficult to make holes in the filter body. In the state of the plug, dust can be properly and effectively filtered out from the inhaled fuel. If the outermost layer of the body is constructed of a mesh fabric made of polypropylene, the difference between the contact angle of the polypropylene to the water and the contact angle with the fuel is set to be 80 degrees or more. In this outermost layer, the effective oil moisture is achieved. The water-repellent layer is capable of achieving effective oil-water separation because the difference between the contact angle of the water and the contact angle with the fuel is set to be more than 8 degrees. . If the filter body is formed into a multilayer structure 'at the same time, when the layers are all made of the same, the fat material is formed', the lamellar to mat-like layers can be laminated (stacked) and then welded to each other. The invention has the advantages of the invention: ▲ According to the invention, the yarn can be used in various climatic and temperature conditions, and the oil pump can be used for a long time and stably. [Embodiment] Hereinafter, a mode for carrying out the invention will be described in detail based on the first to eleventh drawings. The first diagram is a top view of the filter device F, and the second diagram is a bottom view, ίth and The tenth figure shows the cross-sectional shape of the transition device 4, in particular, the second figure shows that the filter device F is installed in one of the fuel tanks T, and the second state, the second switch, represents the filtering of the bag-shaped crucible that constitutes the excess F. The main part of the body 10 is enlarged in cross section. Further, the sixth to eighth figures and the second figure are respectively shown as explanations of the test apparatus arranged to select the test mode of the filter material constituting the filter body 1G, and the ninth diagram That means the sixth to eighth figures The filter device F of the present embodiment is attached to the fuel suction port portion Tb' provided in the fuel tank τ to filter the fuel sucked by the fuel pump (not shown) through the suction port. Typically, the device j is installed at the beginning (upstream end) of the fuel flow path connecting the fuel pump to filter and remove dust and impurities contained in the fuel sucked through the filter device F. Clean fuel. The filter device F is mainly composed of a bag body 1, a tamper-proof member 2, a duct 3, and a receiving portion 4. [Pocket 1] The bag 1 is attached to the fuel tank τ. The suction port portion Tb is connected to the suction port portion Tb and is constituted by the filter body 10. When the negative pressure acts on the suction port portion Tb, the fuel passes through the bag body and is filtered there. It is sucked into the suction port Tb and sent to the internal combustion engine. The filter body 10 can be constructed in a single layer or a multi-layer structure (the embodiment shown is a multi-layer structure), and if it is a filter body 10 of a single-layer structure, if it is a multi-layer structure, it is filtered. At 10, at least one of the layers has energy When the moisture in the fuel tank T is frozen at a low temperature, a water blocking layer l〇a which acts on the pressure of the filter body 10 to prevent the moisture from entering the inside of the transition body 1 is formed. 200835544 [Selection method of the water blocking layer 10a] In order to obtain the above functions, the inventors have measured the water permeable pressure of various materials constituting the water blocking layer 10a of the filter body 1 according to the following test methods 试验 or test method 2 - test method 1 (refer to Fig. 6) The lower end is filled with a filter body which is intended to be a filter material of the water blocking layer 10a, inserted/twisted, inserted into the open container and fixed. The filter material is pre-soaked with fuel. (2) Inject water from the water injection pipe into the container of (1). (3) Calculate the pressure when the water in the container passes through the filter material of (1) and is immersed in the cylinder. - Test method 2 (refer to Fig. 7) (1) The front end outlet of the cylindrical body of the syringe shape is sealed as a water blocking layer. The filter material is pre-soaked with fuel. (2) ft (four) causes the piston to retreat, and the pump fills the cylinder with water. The shape f advances and calculates the amount of pressure of water as it leaks out of the front of the cylinder. 1 The various pre-selected as the water-blocking layer 10a must be installed in the tank of riding and water. In the immersion process, the F = transfer point is placed in contact with the layer above the water layer and placed in the tank, and supported to be positioned under the filter #bubble in water, and the upper part is soaked; : Fig.). After standing still, check the lion's F. In other words, whether or not ice is present inside.丨虿",, table / re-inspection results are shown in the table in Figure 9. The "net material" in the water-repellent sound material in the table refers to "mesh fabric"; "X" stands for "with water seepage", "〇" stands for "no seepage/" and "Fengfeng" stands for "stacked yarn", "flat" stands for "small" and "spun", "SB" stands for "spinning method" "Leg" stands for ";^"" stands for needle 200835544, and various water-blocking layers 10a. According to the test in Figure 8, no water seepage into the filter device F is below the average pore diameter of 20^^, and is less than 4.5. The water that spits 3 does not allow water to pass through. Specifically, the polypropylene has a mesh with an average pore diameter of 19.9/zm, an average pore diameter of 151_ and an average pore diameter of 7·l/zm. Kind. In the present specification, the mesh having the average pore diameter refers to the mesh of the mesh when the filter material is a mesh fabric, and the interfiber gap constituting the cloth when it is not woven, and will be described here. In the present embodiment, the wire is placed in the water, and the water in the fuel tank τ can be utilized; the water-blocking layer of the structure in which the water is infiltrated into the inner side of the filter is generated. In the cold area, it is possible to effectively prevent the water from entering the fuel in the fuel, and the water is sucked into the side of the fuel, and the situation is 0. In this case, the filter body 1 should adopt a single layer structure. The layer is all, and if a multi-layer structure is used, the difference between at least the layer connection (four) and the rotation connection is 8 G degrees or more and the above contact angle of the resin, which means that the water is bitten in the present specification. When it is too fine, when it is on, the crane (4): the figure, the line formed by the tangent of the end face of the drop (the above === when the material is on the 'water ride _ (ie face)), therefore, In this embodiment, the filter body 10 is made of a single #M, and the layer is entirely formed. If a multilayer structure is used, the resin material is made of 'the resin material' and the resin material is selected to have a water system of 80 degrees. The above reason 'even if the fuel is mixed with t = no water, it can prevent moisture from the mesh, that is, the fiber layer Department, and then effective social water into the secrets of the human body filter body The above-mentioned water-blocking layer gamma is made of resin material, ° under the species i temperature condition 200835544, can guarantee the separation of oil and water.

Further, in the illustrated example, the filter unit Ft filter system constitutes a multilayer structure &, and the outermost layer is formed of a mesh fabric and is located inside the layer. The water blocking layer 10a on the side of 200835544 is formed of a non-woven fabric. Thus, the embodiment shown in the figure does not cause wear due to the direct contact of the water blocking layer 1A with the inner wall of the fuel tank τ (usually the bottom surface Ta of the fuel tank). Further, in the illustrated embodiment, the inner layer composed of the non-woven fabric including the water blocking layer 10a on the inner side of the outermost layer has two or more layers, and the average opening diameter of the layer located inside the transition device F ( The aperture is smaller than the average opening diameter (aperture) located at the outer side. With this configuration, the action of the filtering device F can capture dust having a large particle diameter from the non-woven fabric layer located outside the filter body 1 and capture the dust having a small particle diameter by the non-woven fabric layer located inside the filter body 10, and the filter body 10 is in the filter body 10. In the state where the mesh is not easily clogged, the dust can be effectively filtered out from the inhaled fuel. Further, in the illustrated example, each layer constituting the filter body 10 is made of the same material. According to this configuration, the filter device F can be layered (laminated) in layers of sheets or mats, and then welded to each other to be integrated, and processed to form the bag-shaped filter body 10. In the illustrated example, the filter body 10 is as shown in the figure -j, and is the outermost layer lb of the mesh fabric (a flat fabric of PP fibers having a wire diameter of 180/zm, | 70 mesh), at the most The first inner layer of the inner non-woven fabric of the outer layer lb has an average pore diameter of 27//m, and a PP fiber having a diameter of 7/m, by a melt-blown mesh 40g/m2), in the first inner layer i〇c The second 10d of the inner non-woven fabric (PP fiber with an average pore diameter of 15·1 //m, a wire diameter of 5#m, formed by a heterogeneous layer method, mesh 30g/m2), and not woven inside the second inner layer l〇d j three inner layers 10d (having an average pore diameter of 7·1/zm, PP fibers with a wire diameter of 3/zm formed by melt-blown method, mesh 40g/m2), and the inner layer of the third inner layer is not woven by the fourth inner layer 1 Of (having an average pore diameter of 34·4 // m, a pp of 20 // m bp is formed by a spunbonding method, and a mesh of 80 g/m 2 ). The two layers of the filter body, the inner layer 10d and the third inner layer l〇e constitute the water-blocking layer I% and the water-blocking function is obtained (refer to FIG. 11). The filter device F having such a filter body 10 is confirmed to have an effective function of separating oil water and excellent dust trapping function, and forcing the pressure generated by the volume expansion of the frozen water even when the water mixed in the fuel is frozen. The effect of the occurrence of water entering the inside of the filter body 10. Further, in the illustrated example, the bag-like body 1 constitutes a long flat bag-like body having two long sides n, n and two short sides 12, 12. One of the two short sides 12, 12 is shorter than the other side, and the two long sides 11, 11 are gradually inclined and gradually extended as the end of one end is close to the short side of the other end 12, and finally join together. In the illustrated example, the bag-like body 1 has a lower portion constituting portion 13 and an upper portion constituting portion 14. In this example, the long flat filter body 10 is formed such that it can be folded in a white portion at a slightly central portion in the longitudinal direction thereof, and the outer peripheral portion 17 of the folded portion 15 is overlapped and filtered, and the peripheral portion 17 of the second portion is thermally fused. The long edge 12 of the long bag shape as described above can be obtained, and the catheter 3 will be described below. The /1! n30 of the [catheter 3] is connected to the suction port portion Tb, and the other leg of the tube is inserted into the inside of the bag-like body 1 to communicate with each other. The tube 3 is formed into a tubular body having a substantially square cross section, a circular hole 32 in which the mouth hole protrudes, and an insertion hole 34 3 which is accommodated in the first portion of the μ Tb communication and the tongue 33. The other end of the tube 1 is in the suction port portion Tb. In this case, the catheter is inserted into the bag body through the through hole I6. The bent portion 15 is formed of a synthetic resin _ °. In the illustrated example, the above-mentioned squeaking portion of the guide member 3 10 is an integral body in which the f-input member is inserted into the unfolded filter body. < At the 'insertion molding method and the filter body 10 is formed into the elastic piece 35 which protrudes forward at the insertion end of the guide. In the example shown in Fig. 13 200835544, the elastic piece 35 is from the middle position of one of the conduits 3 and the lower edge of the conduit 3 to the middle of the upper edge of the pocket of the pocket body. ) extending and protruding, and / / ^ side 12 side (to form an elongated plate ^ in this example, the length of the elastic piece 1 in the inner surface of the bag 1 will be referred to the receiving portion 4. In the fixed [anti-smashing part 2], the smashing part 2 is fixed on the reinforcing body name of the bag-shaped body 1 =:., from the top and bottom: == the middle part 1° of the column t is composed of synthetic resin, and the The bag-shaped i is provided in the lower portion constituting portion 13 of the bag-shaped body 1 - the dam portion 2 of the upper constituting portion 14 is connected in a state in which the other convex portions 21 are fitted to each other In particular, in the illustrated example, the longitudinal direction of the concave portion of the pain-preventing portion 2 of the lower constituent portion 13 corresponds to the above-mentioned ridge 2 and the upper portion 14 is pain-proof. In the circle of the 2nd part, the convex part 2 which can be inserted into the groove 22 at the second end of the circle forms an opening σ which is open to the outside. The upper part of the upper trap 4 22 = 21 line along the upper part 14 Anti-pain 2 The radial direction forming portion 21 forms a step surface 23 on both sides of the middle portion, and can move the end surface of the cylindrical portion of the tamper portion 2 of the lower portion of the portion 13. In the center, the length direction of the bag body 1 is The convex portion 21 of the 2, or (4) t anti-weak portion 2 can be slidably embedded in the concave portion 2 along the concave direction of the lower anti-pain portion 2. Inside, specifically, the female 彳+, the sliding direction is along the bag body 丨The length of the length is 200835544. In the case of the silvery silver, the sliding of the protrusion 21 has the positional deviation between the lower part of the bag body 1 and the upper part and the part 14 caused by the absorption of the bag body 1 ΐΐϊί Ta The effect of (biased position). In the case of the 'filter device', the 3 end of the tube is fixed by the 3 end of the catheter. The tip of the bag body 1 is usually at the side of the suction port Tb - and the bag body 1 The front end is in contact with the bottom surface Ta of the fuel tank T or the inlet 3:2:! inside the tank. When the bottom of the fuel tank rises to the ai material, the air pressure becomes lower than atmospheric pressure, etc., so that the bottom portion Ta is received from below. The upwardly pushed pocket 1 will have a positional deviation between the constituent parts 14 of the second pseudo ###3", and this In the longitudinal direction, the positional deviation can be formed on the conduit 3 of the shape 1 on the receiving portion 4 (Fig. 5). In the illustrated example, the surface forming portion 14 is respectively The formation of such a receiving portion 4 is composed of a synthetic resin, and is formed of a synthetic resin. The inner surface of the garment body 1 is opposite to the outer surface of the body 1 and the body 10 is attached to the body. 10 is inserted as the inserting part t, and the part 4 is separated by the direction of the length of the middle section of the filter, and the length of the section is adjusted by the length of the middle section The portion 4 body 10 is used as an insert molding method for the insert member, and 15 200835544 is integrally formed on the inner surface of the bag body 1. The s-components ^2, 2 and the receiving portion 4 of the body 1 are in the position of the bag-shaped S?=:::, 2, 2 to ensure the equivalent: t: the ridge & H convex portion 21 can be stably ensured Mechanical docking, and. The unfavorable situation in which the pressure of Debbie changes afterwards. The duct 3 of the inscribed portion Tb is formed to be contactable to the _35 fixed to the bag 4, so as to avoid the fact that the bag = the portion 13 can be touched by the elastic piece %*, the lower frame of the woven basket 1 = Keep-fixed strength to the second part of the fuel τ = Er 2, ^ 35 In addition, the generation of the body 10 caused damage to the corpus callosum 10 occurred. The defensive structure of the face 14 is configured to be embossed with the upper surface, and the constitutive portion 13 of the shape 1 and the upper constituting portion 14 generate a force of deviation. Act on the bag body! At the same time, it is also effective in the sliding of the shape of the bag 1 when the bag body 1 is subjected to such a force, the hair can be prevented from being thinned in the example, since the sliding system is arranged to absorb the potential chain, the bottom surface of the box When Ta is formed on the lower surface of the bag body 1, it is formed. The direction in which the positional deviations of the 卩14 are the same is the same: When the 々面 body 1 is used, it is possible to prevent the bag-like body from being folded.
