- Oil filter assembly having rotation type drain pin [Technical field]
- the present invention relates to an oil filter assembly used for filtering engine oil and in particular discloses that the oil filter assembly on an oil filter combines a rotary drain pin used for discharging engine oil.
- an oil filter assembly needs to be set on the engine oil circulation path to continuously keep engine oil clean.
- Figure 1 is an exploded oblique view of the existing oil filter assembly and Figure 2 shows the structure of the drain bolt installed on the cap of the existing oil filter assembly.
- the existing oil filter assembly comprises the following structures: a casing (10), a replaceable oil filter (20) set in the casing (10), and a detachable cap (30) combined at the opening (15) of the casing (10).
- a first installation part (11) and a second installation part (12) are formed on the other side of the casing (10).
- the first installation part (11) is installed on the engine side (not shown in the figure) with a plurality of connection pieces, while the second installation part (12) is installed on the engine oil cooler side (5) with a plurality of connection pieces.
- a first oil return hole (11a) connected to the engine (not shown in the figure) and a drain hole (l ib) are formed on the first installation part (11), while a second oil return hole (12a) connected to the engine oil cooler (5) and an oil inlet hole (12b) are formed on the second installation part (12). Therefore, contaminated engine oil in the internal circulation of the engine (not shown in the figure) flows through the first oil return hole (11a) and the second oil return hole (12a) into the engine oil cooler (5), and contaminated engine oil is cooled in the engine oil cooler (5).
- the filter (20) comprises filter paper (21) corrugated along the circumference and a support supporting the filter paper (21).
- a top support plate (22a) and a bottom support plate (22b) are respectively equipped at the top and bottom of the support to support the top and bottom of the filter paper (21), and a flow path (23) which engine oil passes by is formed along the centre of the support.
- the cap (30) can detachably be combined with the opening (15) of the casing (10), an external screw part (30a) is formed on the external circumferential surface of the top of the cap (30), and the external screw part (30a) is combined with the internal screw part formed on the internal circumferential surface of the opening (15).
- a sealing element (16) is set between the cap (30) and the casing (10), and the cap (30) and the casing (10) are combined in a sealing manner.
- a bypass valve (40) is formed at the bottom of the flow path (23) of the support, and the bypass valve (40) is combined with the inner side at the centre of the cap (30).
- the nut boss (35) at the centre of the bottom of the cap (30) protrudes downwards, and the metallic drain bolt (50) can detachably be combined with the drain hole (33) in the boss (35).
- a metallic nut fitting (34) is integrated on the internal circumferential surface of the drain hole (33) by means of insertion and injection and an internal screw part (34a) is formed on the internal circumferential surface of the nut fitting (34).
- the drain bolt (50) can firmly be fixed to the drain hole (33) side of the cap (30). Further, a sealing element (55) is set between the external circumferential surface of the drain bolt (50) and the internal circumferential surface of the nut fitting (34) to ensure the tightness between the drain bolt (50) and the nut fitting (34).
- a connecting groove (52), where a wrench can be inserted, is formed at the centre of the head end (51) of the drain bolt (50) and an internal screw part (50a) is formed on the external circumferential surface of the drain bolt (50).
- the external screw part (50a) can detachably be combined with the internal screw part (34a) of the drain hole (33). Therefore, when the operator turns the drain bolt (50) to remove it from the cap (30), the drain hole (33) in the cap (30) is opened and engine oil inside said oil filter assembly is discharged out through said drain hole (33).
- the present invention is intended to provide an oil filter assembly which integrates the drain pin and the filter so that the separation of said drain pin, not desired by the operator, will not happen, said drain pin can quickly be removed to improve the operation efficiency, and the drain bolt or the tool can be prevented from being contaminated with engine oil.
- the oil filter assembly in the present invention comprises the following structures: a casing with an open end; a filter which is inserted in said casing and further comprises a pipe support having a plurality of openings in the side wall, filter paper surrounding the external circumferential surface of said support, a top support plate which is combined with said support and can cover the top of said filter paper, and a bottom support plate which is combined with said support and can cover the bottom of said filter paper; a cap which is combined with said casing in screwed connection mode and can cover the open end of said casing, with the drain nipple having a drain hole protruding downward from the position corresponding to the bottom support plate; a drain pin which is detachably combined with said drain nipple to open/close the drain hole in said drain nipple.
- annular rotation groove with the rotation axis of said casing being its central axis is formed on the bottom surface of said bottom support plate and said drain hole is formed in the position corresponding to said rotation groove.
- Said drain pin comprises the following structures: a body which is inserted into said drain hole in fit mode; a slide block which is located at one lengthwise end of said body and placed on the bottom surface of said rotation groove and can slide along said rotation groove as said cap rotates in the screwed connection direction; a handle which is located at the other lengthwise end of said body and is exposed to the outside of said drain nipple; a sealing element which surrounds the external circumferential surface of said body.
- the entrance width of said rotation groove is smaller than the bottom surface width
- the lateral length of said slide block is greater than the entrance width of said rotation groove
- the longitudinal length of said slide block is smaller than the entrance width of said rotation groove.
- Said slide block is made of a material with elasticity above the standard value.
- the lateral end of said slide block is in the curved shape and the curvature is the same as that of the internal side wall of said rotation groove.
- Marking grooves are formed in the radial direction of said drain nipple on the protruding end, said handle is extended downward and is in the shape of a plate, and when said drain pin rotates to keep said slide block laterally aligned to the radial direction of said rotation groove, the two widthwise ends of said handle are matched to said marking grooves.
- the oil filter assembly in the present invention integrates the drain pin and the filter so that the separation of said drain pin, not desired by the operator, will not happen, said drain pin can quickly be removed to improve the operation efficiency, and the drain bolt or the tool can be prevented from being contaminated with engine oil.

- Figure 3 is a vertical section view of the oil filter assembly in the present invention
- Figure 4 is an oblique bottom view of the cap of the oil filter assembly in the present invention
- Figure 5 is an oblique bottom view of the combined drain pin and filter.
- the oil filter assembly in the present invention is a device which filters engine oil supplied to a vehicle engine and then supplies the filtered oil to the engine again.
- the oil filter assembly comprises the following structures: a casing (100) with an open end (lower end in Figure 1), a filter (200) inserted into said casing (100), a cap (300) which is combined with said casing (100) in screwed connection mode and can cover the open end of said casing (100), with the drain nipple (310) having a drain hole (312) protruding downward from the position corresponding to the bottom support plate (240), and a drain pin (400) which is detachably combined with said drain nipple (310) to open/close the drain hole (312) in said drain nipple (310).
- Said drain hole (312) is formed at the bottom surface of the cap (300). If the casing (100) and the cap (300) are filled with engine oil, the engine oil contained by said casing (100) and cap (300) will be discharged out through said drain hole (312) when the drain pin (400) is removed and the drain hole (312) is opened. On the contrary, as shown in Figure 3, after the drain pin (400) is inserted into the drain nipple (310), engine oil flowing into the casing (100) and the cap (300) will not leak out if the drain hole (312) is closed, and engine oil filtered by the filter (200) is re-supplied to the engine.
- the part where the drain hole (312) is formed is manufactured thin, the following problem exists: after the drain pin (400) is inserted and the drain hole (312) is blocked, said drain pin (400) may incline to one side and easily fall into the drain hole. Therefore, as shown in the embodiment, the part where the drain hole (312) is formed on the bottom surface of said cap (300) is preferably manufactured into a downward-extended pipe shape so as to increase the area of contact with the drain pin (400).
- a safety pin 700 is provided, like shown in the figures 3 and 11 to 13.
- the safety pin 700 is made of plastic, especially as an one piece molded plastic element, and is inserted in a through-hole 600, going through the drain nipple 310 and the safety pin 700.
- the safety pin 700 also prohibit twisting of the drain pin 400, so that the slide block 420 is fixed in the rotation groove 240.
- the through-hole 600 crosses the safety pin 700 below the sealing element 412, so that the sealing effect of the sealing element 412 is not affected.
- the safety pin 700 has elastic elements 800, which grab behind an edge of the through-hole 600, when the safety pin 700 is fully inserted in the through-hole 600, and thus provide a barrier for extract the safety pin 700 out of the through-hole 600.
- the through-hole 600 is going through the drain pin 400 as well as through the walls of the drain nipple 310.
- the through-hole 600 in the drain nipple 310 can be formed as a bore 950 (circular orifice) complementary to the safety pin 700 (see Figure 3, 11) or as unilaterally open aperture 960 (see. Fig. 11).
- the unilaterally open aperture 960 would of course also prevent a rotational movement of the pin 700 and therefore a disengagement of the pin 700 from the groove 242. But if the drain pin 400 is not engaged in the rotation groove 242 with the slide block 420, the unilaterally aperture 960 do not assume axial forces, so that the drain pin 400 can be removed in axial direction. Thus during operation of the oil filter 200, the pressure inside can eject the drain pin 400, if it is not axially fixed through the bore 950 and/or the slide block 420, which is engaged in the rotation groove 242.
- the safety pin 700 also prevent an erroneous assembly, because it only can be inserted into the through-hole 600, if the safety pin 700 and the whole oil filter 200 is assembled in a correct manner.
- the drain pin (400) which opens/closes said drain hole (312) is combined with the drain nipple (310) in fit mode in the oil filter asembly in the present invention and thus the tightness of the drain hole (312) may decrease. Therefore, the external circumferential surface of said drain pin (400) is preferably equipped with an O-ring sealing element (412).
- the sealing element (412) may fall off the internal circumferential surface of the drain hole (312), depending on the insertion distance of the drain pin (400), and thus, the drain hole (312) may be opened, which is not desired by the operator.
- the contact distance between the drain pin (400) and the drain nipple (310) is extended.
- said sealing element (412) will still stay on the internal circumferential surface of the drain hole (312) to increase the reliability of the tightness of the drain hole (312).
- said drain pin (400) is inserted into the drain nipple (310) in fit mode, instead of screwed connection mode, and therefore the time necessary for opening/closing the drain hole (312) can be reduced significantly. Further, it is necessary to rotate the existing drain bolt (50) for several turns before removing the existing drain bolt (50), and therefore, engine oil will flow out and contaminate said drain bolt (50), the working tool, or the hands of the operator when said drain bolt (50) is removed.
- the drain pin (400) when pulled downward, it can be separated from the drain nipple (310) instantaneously, and therefore, engine oil will not flow out of the drain hole (312) and contaminate the drain pin (400) or hands of the operator.
- said filter (200) comprises a pipe support (210) having a plurality of openings in the side wall, filter paper (220) surrounding the external circumferential surface of said support (210), a top support plate (230) which is combined with said support (210) and can cover the top of said filter paper (220), and a bottom support plate (240) which is combined with said support (210) and can cover the bottom of said filter paper (220).
- a bypass valve (500) is equipped at the bottom of the internal flow path of the support (210), that is to say, when the service life of said filter paper (220) ends and cannot filter engine oil normally, engine oil supplied to the inside of said casing (100) moves to the outside of said casing (100) in a roundabout way through the internal flow path in the support (210).
- said casing (100), support (210), and filter paper (220), top support plate (230), and bypass valve (500) are essentially the same as those in the existing oil filter assembly. A detailed description of these structures is omitted here.
- Figure 6 is an oblique view of the drain pin (400)
- Figure 7 is an oblique view of the drain pin (400) sliding along the rotation groove (242) when the cap (300) is combined with the casing (100) in screwed connection mode
- Figure 8 is a horizontal section view of the slide block (420) installed in the rotation groove (242).
- drain pin (400) After the drain pin (400) is inserted into the drain nipple (310), said drain pin (400) can be lifted so that the top of the drain pin (400) touches closely against the bottom surface of the bottom support plate (240).
- a vehicle running, to keep the drain pin (400) from separating from the drain nipple (310), namely, to prevent the drain pin (400) from falling off, it is structurally optimal that the top of the drain nipple (310) is snapped into the bottom support plate (240). That is to say, when said drain pin (400) is inserted into said drain nipple (310), the top of the drain nipple is hung on or released from the bottom support plate (240), depending on the rotation degree.
- annular rotation groove (242) is formed on the bottom surface of said bottom support plate (240), with the rotation axis of the casing (100) being the central axis, and the entrance is narrower than the bottom surface when said rotation groove (242) is manufactured.
- a through-hole (244) can be formed in the external wall of said rotation groove (242) to let engine oil run smoothly.
- said drain pin (400) comprises the following structures: a body (410) inserted into said drain hole (312) in fit mode, a slide block (420) which is located at one lengthwise end (top end in the embodiment) of said body (410) and placed on the bottom surface of said rotation groove (242) and can slide along said rotation groove (242) as said cap (300) rotates in the screwed connection direction, and a handle (430) which is located at the other lengthwise end (bottom end in the embodiment) of said body (410) and is exposed to the outside of said drain nipple (310) when said body (410) is inserted into the drain nipple (310).
- the lateral length of said slide block (420) is greater than the entrance width of said rotation groove (242), and the longitudinal length of said slide block (420) is smaller than the entrance width of said rotation groove (242). Therefore, when said slide block (420) is laterally aligned to the radial direction (see Figure 9) of said rotation groove (242), the slide block (420) will not be separated from the rotation groove (242) and will remain inserted in said rotation groove (242); when said slide block (420) is laterally aligned to the tangential direction (see Figure 10) of said rotation groove (242), the slide block (420) can be inserted into or removed from the rotation groove (242).
- said rotation groove (242) is preferably manufactured into an annular groove with the central axis being the rotation axis of the cap (300) so as to keep said drain pin (400) rotating together with said cap (300) during the rotation of the cap (300).
- said slide block (420) will laterally be aligned to the radial direction of the rotation groove (242), that is to say said slide block (420) remains hung in the entrance of the rotation groove (242), and therefore said slide block (420) can rotate with the rotation axis of the cap (300) being the central axis and the cap (300) can rotate free of interference from the drain pin (400).
- the slide block when said slide block (420) slides along the rotation groove (242), the slide block is preferably manufactured into a structure with polygonal edges to keep the slide block (420) always laterally aligned to the radial direction of the rotation groove (242) and one lateral end
- the lateral end (422) of said slide block (420) can be manufactured into a curved shape and the curvature is the same as that of the internal side wall of the rotation groove (212).
- said slide block (420) will not rotate at all in the direction indicated by arrows in Figure 8 and thus the reliability of the combination between the slide block (420) and the rotation groove (242) can further be improved.
- said slide block (420) is made of a material with almost no elasticity, such as a metal, you cannot rotate said drain pin (400) since the edges of said slide block (420) are snapped into the internal side wall of the rotation groove (242). Therefore, said slide block (420) should be made of a material with elasticity above the standard value, such as synthetic resin, so that the edges of the slide block can cross the internal side wall of the rotation groove (242) when you apply a force, but said slide block will not rotate under the action of vibrations of the engine.
- FIG. 9 and Figure 10 show the service state of the oil filter assembly in the present invention.
- marking grooves (314) are formed in the radial direction of the drain nipple (310) on the protruding end of the drain nipple (310) and said handle (430) is manufactured into a downward extended plate.
