    Filter Device {FILTER DEVICE}
    The present invention relates to a filter device for filtering liquid by a filter element contained in the device.
    Japanese Patent Unexamined Publication No. 1, in which a conventional filter device having a replaceable filter element is first filed by the applicant of the present application. 7-100310, the filter element of which is shown in FIG.
    The cartridge type filter element 02 is housed in a cylindrical container 01 having a closed bottom, and a fixing plate 03 serving as a lid is connected to the open end (opening) of the container through an O-ring (sealing member 04). Mounted to seal the open end. Ring nut (ring-type fixing member, 05) is formed on the outer peripheral surface of the screw thread is formed on the outer thread portion to fix the fixing plate 03 to the container (01).
    The O-ring 04 held between the container 01 and the stationary plate 03 is compressed in the axial direction to form an axial seal, but not a radial seal.
    Therefore, if the ring nut 50 is not completely threaded on the fixing plate, when the ring nut is tightened, the O-ring is not compressed or improperly compressed between the container 01 and the fixing plate 03. There is a possibility that a good seal cannot be obtained.
    In particular, when foreign matter is interposed between the threaded portion of the ring nut 05 and the fixing plate 03 or when dust or foreign matter is present in the threaded groove, the screw is not completely made, and the seal is incomplete.
    The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a filter device which allows a good seal to be obtained between the container and the lid even if they are fixed together improperly.
    A tubular container having a closed bottom, a filter element housed in the container, a lid having a communication hole for sealing an open end of the container and communicating with the inside and the outside of the container, the container and the lid together A fixing member for fixing and an annular elastic seal member are mounted in a gap formed between the peripheral wall of the open end of the container and the peripheral surface of the open end of the lid located opposite the peripheral wall, and the radius of the annular elastic seal member. In the filter device according to the first aspect of the present invention, the seal width is larger than the width of the gap in the radial direction, and the seal member includes an annular elastic seal member that radially seals the gap waterproof when the filter device is assembled. The above object is achieved by this.
    A radial seal width of the annular elastic seal member, mounted in a gap formed between the peripheral wall of the open end of the container and the peripheral surface of the open end of the lid, which is opposite the peripheral wall, is radially greater than the width of the gap. Since it is large, the elastic seal member is compressed in the gap while being compressed in the radial direction during the assembly operation. Therefore, even if it is somewhat inappropriate to fix the lid to the container by the fixing member, a waterproof seal is formed, thereby maintaining the sealing effect.

A lid having a communication hole communicating with an inner side and an outer side of the inner side, and a fixing member for holding the container and the lid together, the lid being in an axial direction opposite the stepped portion of the container, the radius An opposing circumferential wall opposite the other diametrical portion in a direction, such that the peripheral portion and the opposing circumferential wall cooperate with the stepped portion and the other diameter wall of the container, and are mounted in the gap An annular elastic seal member held between the stepped portion of the container and the peripheral portion of the lid is provided during the assembling operation. Axially compressed so that the seal member expands and deforms in a radial direction, thereby forming an annular elastic seal member that forms a waterproof seal between the other diameter portion of the container and the opposite peripheral wall of the lid. The above object is also achieved by a filter device according to the second aspect.
    When the lid is secured to the container by the fixing, the elastic seal member is axially compressed between the stepped portion of the container and the periphery of the lid so that the elastic seal member expands and compresses in a radial direction so that the different diameter of the container A watertight seal is formed between the portion and the peripheral wall opposite the lid. Therefore, if the sealing member is compressed to some extent in the axial direction by the fixing operation, a good seal can be obtained even if the fixing is somewhat inappropriate.
    In the above-described filter device according to the first and second aspects of the present invention, the open end of the circumferential wall of the open end of the container is advantageously curved in a direction to avoid the sealing member fixed on the circumferential surface of the lid.
    During the assembly operation, the elastic seal member is press-fitted into the radial gap so that the open end of the vessel peripheral wall forming the gap is curved to avoid the seal member. With this structure, the seal member can be inserted into the gap without damaging the seal member, and a good sealing effect can be maintained.
    In the above filter device, the indicator is preferably disposed on the outer side of the container and covered with a heat shrinkable member having light transmission.
    Since the indicator is covered with a heat-shrinkable member having light transmission, the instructions on the indicator are visible through the heat-shrinkable member.

The taper portion 33 extends inward from the lower end of the inner circumferential wall 32 through the horizontal bottom portion 33a, and the taper portion 33 is gently inclined upward. The cylindrical outlet portion 34 is formed on the inner circumference of the tapered portion 33.
    The outer diameter of the fixing plate 30 is slightly larger than the diameter of the large diameter portion 14 of the container 10, and the outer thread 35 is formed on the outer peripheral surface of the peripheral portion 31.

    The annular seal member 42 is fixed to the lower side of the horizontal bottom portion 33a of the fixing plate 30.
    The ring nut 50 has a large diameter cylindrical portion 51 having a smooth cylindrical surface, and a polygonal tubular portion 53 having a small diameter formed at one end of the cylindrical portion 51 through a step 52. ).
    Therefore, the ring nut 50 is rotated by the rotary tool combined with the polygonal tubular portion 53, whereby the ring nut 50 has a simple structure, so as not to have any projections for coupling with the tool. It is easily produced by pressing.
    The inner diameter of the cylindrical portion 51 is slightly larger than the outer diameter of the large diameter portion 14 of the vessel 10, and the diameter of the engraved circle of the polygonal tubular portion 53 is the cylindrical portion 11 of the vessel 10. Slightly larger than the outer diameter of), the cylindrical portion 11 may pass through the polygonal tubular portion 53, but the large diameter portion 14 may not pass through the polygonal tubular portion 53. do.
    It is formed on the outer circumferential surface of the fixing plate 30, the inner thread 54 for screwing the outer thread 35 is formed on the inner circumferential surface of the cylindrical portion (51).
    A method of assembling the oil filter device 1 having such a configuration will be described below. However, in this embodiment, prior to this assembling operation, a rectangular caution label 60 serving as an indicator portion is attached to the portion of the cylindrical portion 11 of the container 10, and the surrounding label 60 is It is covered with a heat shrinkable member 65 made of synthetic resin.
    The heat shrinkable member 65 is made of a light transmissive synthetic resin such as vinyl chloride, polyethylene, or polyester, which is transparent or shrinks when heat is applied. The heat shrinkable member 65 is slightly larger in outer diameter than the cylindrical portion 11 of the container 10, and is formed in a cylindrical shape shorter than the cylindrical portion 11 in the axial direction. Two parallel cut dotted lines 66 are formed on the heat shrinkable member 65, extend in the axial direction, and that portion of the heat shrinkable member 65 lying between the two cut lines 66, 66 is the heat shrinkable. It extends slightly beyond one edge of the member 65 to form the removal tab 67.
    This cylindrical heat shrink member 65 is installed on a portion of the cylindrical portion 11 of the container 10 to which the caution label 60 is attached, and when heat is applied to the heat shrink member 65. The member 65 contracts the diameter so that the close contact with the outer surface of the container is maintained, and the heat shrinkable member 65 is in close contact with the cylindrical part 11 of the container 10 over its entire circumference. The outer surface of the side cover) is located between the polygonal surface 11a formed at its upper end and the large diameter portion 14 formed at its lower end.
    The caution label 60 is held relative to the cylindrical portion 11 of the container 10 by the heat shrink member 65, and the outer surface of the caution label 60 is protected by the heat shrink member 65. .
    The heat shrink member 65 is transparent and an indication on the caution label 60 can be seen through the heat shrink member 65.
    The assembling work is performed by the following method using the container 10 having the cylindrical portion covered with the heat shrinkable member 65 in this manner.
    First, the leaf spring 16 is inserted into the container 10 and is held in position on the bottom portion 12 while bending the support arm 16a. Subsequently, when the filter element 20 is inserted into the container 10, with the relief valve 25 first inserted into the container 10, the element plate 22 is connected to the leaf spring 16. The leaf spring 16 is elastically deformed in contact with the distal end, thereby pushing the filter element 20 in the removal direction.
    On the other hand, the valve 40 is fitted to the outlet portion 34 of the fixed plate 30, and the O-ring 18 is mounted to the peripheral portion 31 so as to fit to the inner circumferential wall 32.
    In FIG. 5, the seal width w of the O-ring 18 in the radial direction is greater than the width d of the radial gap between the large diameter portion 14 of the container 10 and the inner circumferential wall 32 of the fixed plate 30. .
    Therefore, since the outer diameter of the O-ring 18 fitted to the outer circumference of the inner circumferential wall 32 of the fixed plate 30 is slightly larger than the inner diameter of the large diameter portion 14 of the container 10, When the opening end is closed by the fixing plate 30, the O-ring 18 is squeezed and deformed radially between the inner circumferential wall 32 and the large diameter portion 14.
    The end end of the large diameter portion 14 of the container 10 is curved outwardly to form the curved portion 14a, and thus, in this assembly, the gently curved surface of the curved portion 14a is formed by the O-ring 18. ) And then the O-ring 18 is easily pressed and deformed. Therefore, the O-ring 18 will not be damaged and the sealing ability is prevented from being lowered by the damage of the O-ring 18.
    When assembled, the deformed O-ring 18 thus forms a radial seal between the inner circumferential wall 32 and the large diameter portion 14.
    If the end end of the large diameter portion 14 of the container 10 is bent outwardly, this end end will not damage the O-ring 18. However, if this end end is curved outward as in this embodiment, the curved surface of this curved portion 14a acts as a guide surface for guiding the O-ring 18 when assembling, thereby facilitating the assembling work.
    Subsequently, each of the four notches 36 formed on the periphery 31 of the fixing plate 30 is fitted to the four engagement protrusions 15 on the large diameter portion 14 of the container 10, so that the engagement protrusions 15 are Each fits into the notch 36, thereby positioning the stationary plate 30 radially relative to the container 10.
    The outlet portion 34 protruding from the center of the fixing plate 30 is inserted into the opening 23a in the flange 23 of the filter element 20.
    The filter element 20 when the opening portion 23a is engaged with the groove portion 40c of the valve 40 disposed coaxially with the outlet portion 34 when the outlet portion 34 is inserted into the opening portion 23a. Is pushed into the container 10 against the bias of the leaf spring 16, and then the engaging projection 15 of the container 10 is fitted to the notches 36 of the fixed plate 30, respectively.
    Since the radial seal is formed by the O-ring 18, a space isolated from the outside by the container 10 and the fixed plate 30 is formed. Since the opening 23a of the flange 23 formed at the lower end of the filter element 20 is fitted into the groove 40c in the valve 40, the fixing portion 40a formed at the end near the center of the valve 40 is Of the filter 21 which is held between the opening 23a and the taper portion 33 of the fixed plate 30 and thereby communicates with the outside of the filter 21 (which leads to the inlet portion 37) and the outlet portion 34. The interiors do not communicate with each other.
    Next, the ring nut 50 is first opposed to the bottom 12 of the container 10, and then fitted to the container 10 so that the ring nut 50 is attached to the large diameter portion 14. Fit. Next, the internal thread on the cylindrical portion 51 is accurately aligned with respect to the external thread 35 of the fixing plate 30, and the ring nut 50 is rotated while keeping the container 10 fixed, thereby causing internal threading. Engage (54) with the external thread (35).
    At this time, the ring nut 50 may be rotated by a rotary tool that is engaged with the polygonal tubular portion (53).
    When the container 10 is fixed, the fixing plate 30 is fixed to the container because each of the engaging protrusions 15 engages the notches 36, and thus, when the ring nut 50 is rotated, the fixing plate 30 rotates. Will not, and the threaded engagement is smoothly achieved.
    As the outer thread 35 of the fixing plate 30 and the inner thread 54 of the ring nut 50 are engaged with each other, the fixing plate 30 is threaded to the ring nut 50. At this time, the stepped portion 13 of the container 10 comes into contact with the stepped portion 52 of the ring nut 50, thereby preventing the axial movement of the container 10 and thus the filter element 20. The holding plate 30 is threaded to the ring nut 50 while pressing on 10).
    Therefore, the fitting portion 40a of the valve 40 is tightened with a large pressure, so that the inside and the outside of the filter 21 do not communicate with each other, and in this state of engagement, the inner circumferential wall of the fixing plate 30 The O-ring 18 fitted to the outer circumference of the 32 is held between the periphery 31 of the fixed plate 30 and the step 13 of the container 10 and is therefore subjected to axial pressure.
    Therefore, the O-ring 18 axially compressed as described above attempts to expand in the radial direction, so that an O-ring forming a degree of radial seal between the inner circumferential wall 32 and the large diameter portion 14 first. 18 is squeezed at radially high pressures between them, thereby providing a more reliable sealing capability.
    The inner circumferential wall 32 is formed integrally with the fixing plate 30, therefore, it is not necessary to install any means for forming a seal therebetween, and the number of parts is also reduced.
    Even if the fastening of the ring nut 50 is somewhat insufficient due to the foreign matter attached to the threaded portion, a certain amount of seal which does not leak liquid is formed in the radial direction, and when a certain amount of pressure is applied in the axial direction, the radius The directional seal is improved, and thus the necessary sealing ability can be easily secured.
    1 shows a state in which the ring nut 50 is completely screwed to the fixing plate 30. In this state, the heat shrinkable member 65 is thinly disposed in the gap between the outer circumferential surface of the cylindrical portion 11 of the container 10 and the inner circumferential surface of the polygonal tubular portion 53 of the ring nut 50. Since closing the ring nut 50, foreign matter, dust and dirt will not enter.
    The oil filter device 1 assembled in this way is mounted on the engine of the vehicle.
    A tubular member externally threaded protrudes from the mounting surface of the engine, and the threaded member meshes with the internal thread 38 formed on the inner circumferential surface of the outlet portion 34.
    At this time, by rotating the container 10, the fixing plate 30 can be rotated with it, and such threading is easily achieved.
    On the contrary, the container 10 is rotated in the reverse direction to remove the oil filter 1 from the mounting portion of the engine, and the ring nut 50 is rotated to release the threaded engagement with the fixing plate 30. By doing so, the filter device can be disassembled as shown in FIG. 3 and only the filter element 20 can be easily replaced with a new one.
    Since the engaging projection 15 is engaged with each notch 36, the container 10 and the fixed plate 30 will not move together with respect to each other, so that the O held between the container 10 and the fixed plate 30 -The ring 18 and the valve 40 will not be damaged and a high sealing capacity can be ensured.
    In this embodiment, when the open end of the container 10 is closed with the fixing plate 30, four engagement protrusions 15 extending from the large diameter portion 14 of the container 10 are connected to the four of the fixing plate 10. By engaging each of the notches 36 the vessel and the stationary plate are positioned radially relative to each other. However, if the axial length of the large diameter portion 14 is increased, positioning can be achieved in the radial direction by the large diameter portion 14.
    Although the open end of the container is formed with a small diameter portion passing through the stepped portion, the peripheral wall diameter of the fixed plate is larger than the small diameter portion, and even if the structure in which the open end is arranged in a relationship surrounding the small diameter portion is used, The O-rings provided in the gaps between the peripheral walls are pressed radially to form a seal that does not leak liquid.
    Since the surface of the caution label 60 is covered with the heat shrinkable member 65, damage to the instructions of the caution label 60 from the outside, such as flying stones, is prevented, so that the instructions are clearly visible. Can be maintained.
    The heat shrinkable member 65 not only protects the caution label 60 but also protects the surface of the other portion of the cylindrical portion 11 of the container 10.
    To repair or replace the filter element, rotate the container 10 in the reverse direction, remove the oil filter 1 from the mounting of the engine, rotate the ring nut 50 and rotate the polygon of the ring nut 50. Engaged in the fixed plate 30 to the tubular portion 53 is to be released from the engagement with the rotary tool. By doing so, the filter device can be disassembled as shown in FIG. At this time, when removing the ring nut 50 from the cylindrical portion 11 of the container 10, the cylindrical portion 11 may be damaged by the ring nut 50, but the caution label 60 is heat shrinked. It is protected by the member 65.
    If damage from the outside is repeatedly applied to the container so that the instructions of the caution label cannot be clearly seen, or if the scratch is deep enough to reach the caution label 60, pull out the removal tab 67 and thereby, the heat shrinkable member. 65 is easily peeled off along the two cut lines 66, 66, replacing the caution label 60 with a new one and covering this new caution label with a new heat shrink member 65.
    The instructions are written on the caution label so that clear instructions can be provided by replacing the caution label, which is easier than when the instructions were printed on the cylindrical portion of the container 10.
    Even if the instruction is printed on the cylindrical portion of the container 10, the heat shrinkable member is protected from damage from the outside.
    If an indicator is provided on the back or front side of the heat shrinkable member, the indicator is replaced with a new one at the same time when the heat shrinkage is replaced with a new one, thereby making the replacement operation easier.
    Instructions on the indicator may be formed by printing, or may be provided by a label or the like attached to the container.
    When the indicator is provided on the outer surface of the heat shrinkable member, the heat shrinkable member does not need to have light transmitting characteristics.
    In the above embodiment, even when the container 10 to which the heat shrinkable member 65 has been previously attached to cover the caution label 60 is used in assembling the filter apparatus, the heat shrinkable member 65 after assembling the filter apparatus 1 is assembled. ), And in this case, the lower end of the heat shrinkable member 65 is arranged as close to the ring nut 50 as possible so that the polygon of the cylindrical portion 11 and the ring nut 50 of the container 10 can be The heat shrinkable member 65 is attached to the container so as to cover the gap between the tubular parts 53 so that foreign matter, dust and dirt do not enter the ring nut 50.
    In this embodiment, the caution label 60 is provided on the cylindrical cylindrical portion 11 of the container 10, and the heat shrink member 65 is attached only to this cylindrical cylindrical portion 11. However, as shown in FIG. 7, the caution label 70 may be provided on the polygonal surface 11a of the cylindrical portion 11, in which case the heat shrinkable member 75 is extended to extend the polygonal surface 11a. Cover it.
    Bend the caution label 70 from the corner of the polygonal face 11a to secure the caution label 70 to the polygonal face 11a of the container 10 to ensure that the caution label 70 does not circumferentially rotate with respect to the container. Attach.
    Next, another embodiment will be described with reference to FIGS. 8 and 9.
    The filter device itself has the same configuration as described for the previous embodiment and the same reference numerals each denote corresponding components.
    In this embodiment, the caution label 80 is provided on the cylindrical cylindrical portion 11 of the container 10 and opened to cover the polygonal tubular portion 53 of the cylindrical portion 11 and the ring nut 50. The shrinking member 85 is applied, and thus the caution label 80 is covered with this heat shrinking member 85.
    Therefore, when assembling the filter device 1, the heat shrinkable member 85 is attached to the filter device.
    Since the heat shrinkable member 85 covers the outer circumferential surface of the cylindrical cylindrical portion 11 of the container 10 and the outer circumferential surface of the polygonal tubular portion 53 of the ring nut 50, the heat shrinkable member 85 is a container. It is possible to completely cover the gap between the cylindrical portion 11 of (10) and the polygonal tubular portion 53 of the ring nut 50, thereby preventing foreign matter, dust, dirt and water from entering the ring nut 50. It can be reliably prevented.
    Two cutting lines 86 and 86 are formed on the heat shrinkable member 85, and the cutting lines extend axially from the upper end to the lower end thereof so that the heat shrinkable member 85 can be easily removed. The removal tab 87 extends slightly beyond its upper end.
    In this embodiment, when replacing or repairing the filter element, the heat shrinkable member 85 should be removed, wherein the heat shrinkable member 85 can be easily and quickly removed as described above.
    In this embodiment, the heat shrinkable member 85 may extend upwards to cover the polygonal surface 11a or downwardly to cover the cylindrical portion 51 of the ring nut 50, and so on By this, the surface area of the filter device 1 which is protected from damage from the outside can be increased.
    The heat shrink member itself may have an indicator, which may be provided on the front or back side of the heat shrink member 85 or in the heat shrink member 85. In particular, when the indicator is provided in or on the heat shrinkable member 85, the heat shrinkable member needs to have light transmitting characteristics.
    When the surface of the heat shrinkable member is damaged so that the indicator cannot be clearly seen, the heat shrink member is replaced with a new one with the instructions, and in this way, the indicator can always be clearly seen, which can replace the heat shrink member. It only needs to be done, which makes the task simpler.
    The present invention is based on Japanese Patent Application Nos. 10-204056 and 10-215618, which are incorporated herein by reference.
    Although described in accordance with the preferred embodiment of the present invention, various changes and modifications may be made thereto without departing from the present invention, and all such changes and modifications falling within the spirit and scope of the present invention are included in the appended claims. It will be apparent to those skilled in this field.
    According to the filter device according to the present invention, even if it is somewhat inappropriate to fix the lid to the container by the fixing member, a waterproof seal is formed, thereby maintaining the sealing effect.
    In addition, according to the above-described filter device according to the present invention, the indicator is easily replaced, and keeps a clearly visible state at all times with a simple operation of low cost.
    Further, according to the above filter device according to the present invention, intrusion of foreign matter, dust, and dirt is prevented, and the indicator is protected against damage from the outside that is likely to occur when the ring nut is detached and detached for maintenance purposes.
    Further, according to the filter device according to the present invention, since the heat shrinkable member can be axially torn along the cutting line without using any tool, it can be easily removed from the container. Therefore, the heat shrinkable member can be exchanged more easily.
