Description

TECHNICAL FIELD

[0001] The present application relates to the field of oil injection lubrication, in particular to a distributor with bypass system for lubrication system and a method for realizing progressive distribution of lubricating oil. BACKGROUND

[0002] The function of lubrication system is to deliver a certain amount of lubricating oil to the surface of parts in relative motion, so as to realize liquid friction, reduce frictional resistance, reduce the wear of machine parts, and clean and cool the surface of parts.

[0003] At present, intelligent centralized lubrication in lubrication system is the development direction, but in single-line centralized lubrication, if the number of lubrication points is large, it is difficult to accurately deliver oil to the lubrication points, and generally a progressive distributor is used. The progressive distributor realizes the quantitative oil supply of each lubrication point, because the progressive distributor is a volumetric type, the oil output is constant each time, so the amount is accurate, and the use requirements of the lubrication point can be met through the control system.

[0004] However, the currently used progressive distributor has a fatal defect. If the oil is not clean and mixed with impurities, the valve core of the progressive distributor will be blocked, so that the whole progressive distributor cannot work. Since the progressive distributor relies on the reciprocating movement of the valve core to discharge oil from each port, when one valve core is blocked, the next valve core will not move, and so on, causing the whole system to malfunction. If the progressive distributor has multiple valve cores, corresponding to multiple oil outlets, when one valve core is blocked, the corresponding lubrication point of the distributor cannot be lubricated, which can easily cause damage to the equipment and cause immeasurable loss to the user. At the same time, because the progressive distributor is generally very expensive, it is not convenient to disassemble and repair, which will greatly increase the user's use and maintenance cost.

[0005] Therefore, a new type of distributor for lubrication system is needed. Such a distributor can solve the defects of the current progressive distributor and realize the blocking of one valve core without affecting the normal work of other valve cores. SUMMARY

[0006] In order to solve the above technical problems, the present application provides a distributor with bypass system and a method for realizing progressive distribution of lubricating oil, which can realize the blocking of one valve core without affecting the normal work of other valve cores.

[0007] In order to realize the distributor with bypass system and the method for realizing progressive distribution of lubricating oil, the present application adopts the following technical solutions.

[0008] In one aspect, the present application discloses a distributor with bypass system, comprising:

[0009] a main oil inlet;

[0010] at least two oil inlet pipes for oil inlet through the main oil inlet;

[0011] a plurality of cavities respectively connected to the at least two oil inlet pipes, each cavity being provided with a valve core and being movable in the cavity;

[0012] wherein the first cavity is provided with a passage one, a passage two and a passage three on the left side of the first cavity and the right side of the first cavity, respectively, one end of the left side passage one and the right side passage one of the first cavity is connected to the first cavity, respectively, and the other end is connected to a left outlet and a right outlet, respectively; one end of the left side passage two and the right side passage two of the first cavity is connected to the first cavity, respectively, and the other end is connected to the left side end and the right side end of the next adjacent cavity, respectively; one end of the left side passage three and the right side passage three of the first cavity is communicated with the oil passage of the first cavity through one of the oil inlet pipes, respectively, and the other end is connected to a corresponding outlet assembly of the next adjacent cavity, respectively;

[0013] the intermediate level cavities are respectively provided with a passage one, a passage two and a passage three on the left side of the respective cavity and the right side of the respective cavity, one end of the left side passage one and the right side passage one of each intermediate level cavity is connected to the respective intermediate level cavity, respectively, and the other end is connected to a corresponding outlet assembly of the respective intermediate level cavity, respectively; one end of the left side passage two and the right side passage two of each intermediate level cavity is connected to the respective intermediate level cavity, respectively, and the other end is connected to the left side end and the right side end of the next adjacent cavity, respectively; one end of the left side passage three and the right side passage three of each intermediate level cavity is communicated with the oil passage of the respective intermediate level cavity through one of the oil inlet pipes, respectively, and the other end is connected to a corresponding outlet assembly of the current level cavity and a corresponding outlet assembly of the next adjacent cavity, respectively;

[0014] the last level cavity is provided with a passage one on the left side of the last level cavity and the right side of the last level cavity, one end of the left side passage one and the right side passage one of the last level cavity is connected to the last level cavity, respectively, and the other end is connected to a corresponding left outlet assembly and a corresponding right outlet assembly of the last level cavity, respectively; and

[0015] a left return passage and a right return passage, one end of the left return passage is connected to the left side end of the first cavity, and the other end is communicated with the oil passage of the right side passage three of the intermediate level cavity of the previous level of the last level cavity; one end of the right return passage is connected to the right side end of the first cavity, and the other end is communicated with the oil passage of the left side passage three of the intermediate level cavity of the previous level of the last level cavity;

[0016] wherein the right side passage three of the first cavity and the right side passage three of each intermediate level cavity are communicated with the oil passage of the right side outlet assembly of the respective intermediate level cavity, respectively; and,

[0017] wherein the left side passage three of the first cavity and the left side passage three of each intermediate level cavity are communicated with the oil passage of the left side outlet assembly of the respective intermediate level cavity, respectively.

[0018] In one embodiment, the first cavity right side passage two intersects with the first cavity right side passage three and the oil passage is communicated therebetween; each intermediate cavity right side passage two intersects with its right side passage three and the oil passage is communicated therebetween; the first cavity left side passage two intersects with the first cavity left side passage three and the oil passage is communicated therebetween; and each intermediate cavity left side passage two intersects with its left side passage three and the oil passage is communicated therebetween.

[0019] In one embodiment, each oil inlet pipe is parallel to each other and perpendicular to each cavity.

[0020] In one embodiment, each outlet assembly comprises a spool, an outlet at one end of the spool, a spring two connected at one end to the outlet to press against the spool, a top pin below the spool and a spring one to press the top pin. When the system pressure is not applied to the spool, the spring two is in an extended state and presses the spool, so that the spool disconnects the oil passage of the two passage threes connected to the spool. When the system pressure rises to a threshold value, the spring two is compressed, the spool is lifted, so that the oil passage of the two passage threes connected to the outlet assembly is connected, and the passage one connected to the outlet assembly is cut off.

[0021] In one embodiment, the spool of the outlet assembly has a groove on the side surface thereof. When the spool is lifted and moves to a position where the groove is aligned with the top pin, the top pin is pushed into the groove of the spool under the action of the spring one.

[0022] In one embodiment, the distributor comprises two oil inlet pipes and four cavities.

[0023] In another aspect, the present application discloses a method for progressive distribution of lubricating oil by the distributor with bypass system as described above.

[0024] In one embodiment, when the spool in an intermediate cavity is blocked on one side and the spools in other cavities are all working normally, the spool in the blocked side outlet assembly corresponding to the intermediate cavity is lifted, so that the oil passage of the two passage threes connected to the outlet assembly is connected, and the passage one connected to the outlet assembly is cut off.

[0025] In one embodiment, the lubricating oil flows into the passage two of the blocked side of the intermediate cavity through the two passage threes connected to the blocked side outlet assembly, thereby pushing the spool in the next cavity to move in the direction opposite to the blocked side, completing the oil inlet. And, as the spool in the next cavity moves in the direction opposite to the blocked side, the lubricating oil in the next cavity is pushed into the other side passage two of the intermediate cavity, then through the oil inlet pipe communicated with the other side passage two, and then through the other side passage three of the previous cavity communicated with the oil inlet pipe, the other side passage two of the previous cavity, and the other side passage one of the previous cavity, to discharge the lubricating oil, completing the oil outlet.

[0026] In one embodiment, the lubricating oil enters the other side passage two of the intermediate cavity through the other side passage three of the intermediate cavity, thereby pushing the spool in the next cavity to move to the blocked side to complete the oil intake. As the spool in the next cavity moves to the blocked side, the lubricating oil in the next cavity enters the blocked side passage two of the intermediate cavity, then enters the blocked side passage three of the intermediate cavity, enters the blocked side passage three of the upper cavity connected with the blocked side outlet assembly of the intermediate cavity, enters the blocked side passage two of the upper cavity, and then enters the corresponding blocked side outlet of the upper cavity through the blocked side passage one of the upper cavity to discharge the lubricating oil and complete the oil discharge.

[0027] The distributor with a bypass system and the method for realizing progressive distribution of lubricating oil solve the defects of the current progressive distributor, realize that one spool is blocked without affecting the normal work of other spools. In the lubricating system, only the lubrication point corresponding to the blocked spool is without grease, and the lubrication points corresponding to other spools can obtain normal oil amount, which ensures the normal operation of the equipment and reduces the cost of use and maintenance, thereby saving a large amount of funds for users.

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely exemplary and not restrictive.

[0062] See now Figure 1 and Figure 2Figure 1 shows a progressive distributor system with bypass system structure diagram. As shown in the figure, the progressive distributor system includes main inlet 1, inlet pipe 1 2, inlet pipe 2 3, A right channel 1 4, A right channel 2 5, A right channel 3 6, B right channel 1 7, B right channel 2 8, B right channel 3 9, C right channel 1 10, C right channel 2 11, C right channel 3 12, D right channel 1 13, right return channel 14, left return channel 15, A left channel 1 16, A left channel 2 17, A left channel 3 18, B left channel 1 19, B left channel 2 20, B left channel 3 21, C left channel 1 22, C left channel 2 23, C left channel 3 24, D left channel 1 25, A valve core 26, B valve core 27, C valve core 28, D valve core 29, No. 1 outlet assembly 30, No. 2 outlet 31, No. 3 outlet assembly 32, No. 4 outlet assembly 33, No. 5 outlet assembly 34, No. 6 outlet 35, No. 7 outlet assembly 36, No. 8 outlet assembly 37, cavity 1 38, cavity 2 39, cavity 3 40, cavity 4 41.

[0063] Cavity 1 38, cavity 2 39, cavity 3 40, cavity 4 41 are parallel to each other. A valve core 26 is located in cavity 1 38, B valve core 27 is located in cavity 2 39, C valve core 28 is located in cavity 3 40, and D valve core 29 is located in cavity 4 41. Main inlet 1 is divided into two oil supply routes, namely inlet pipe 1 2 and inlet pipe 2 3. Inlet pipe 1 2 and inlet pipe 2 3 are parallel and generally perpendicular to cavity 1 38, cavity 2 39, cavity 3 40, and cavity 4 41.

[0064] Still referring to Figure 1 , A right channel 2 5 intersects with A right channel 3 6, B right channel 2 8 intersects with B right channel 3 9, C right channel 2 11 intersects with C right channel 3 12, A left channel 2 17 intersects with A left channel 3 18, B left channel 2 20 intersects with B left channel 3 21, and C left channel 2 23 intersects with C left channel 3 24.

[0065] Attention is drawn to Figure 4 , 9 , 14, 19, 24, 29, No. 1 outlet assembly 30, No. 3 outlet assembly 32, No. 4 outlet assembly 33, No. 5 outlet assembly 34, No. 7 outlet assembly 36, and No. 8 outlet assembly 37 are respectively composed of valve core, spring 1, top pin, spring 2, plug 1, plug 2, and outlet.

[0066] Now take Figure 4 as an example to illustrate the structure and working principle of each outlet assembly. Figure 4 is a structure diagram of No. 3 outlet assembly 32. As Figure 4As shown, the No. 3 outlet assembly 32 includes a right top pin 32-1, a right spring 32-2, a right plug 32-3, a right valve core 32-4, a right spring 32-5, a right plug 32-6, and an outlet 32-7. When the right valve core 32-4 is not under system pressure, the right spring 32-5 is extended and presses against it. When the system pressure increases, the right valve core 32-4 rises under a specific pressure (in this embodiment, it moves to the right), and the right spring 32-5 is compressed. The right top pin 32-1 is pressed against the right spring 32-2. After the right valve core 32-4 rises, the right top pin 32-1 is pushed and locked into the groove of the right valve core 32-4 by the right spring 32-2.

[0067] The following example, using a single blocked valve core, illustrates how a distributor system can complete the oil inlet and outlet processes even when a valve core is blocked.

[0068] 1. Valve core B is blocked on the right side, while other valve cores are working normally.

[0069] 1. Valve core B is blocked on the right side, and oil inlet pipe 2 is blocked.

[0070] like Figure 3-4 As shown, valve core 27 (B) is blocked on the right side. Oil enters through main inlet 1 and then through inlet pipe 2 (B). Lubricating oil enters right channel 2 (A) 5, pushing valve core 27 (B) to the left. However, because valve core 27 (B) is blocked on the right side, it cannot be pushed. Since the system has no other channels for pressure relief, the system pressure increases, and the pressure in right channel 3 (A) 6 also increases. When the system pressure exceeds the elastic force of right spring 2 (B) 32-5 in outlet 3, the lubricating oil pushes right valve core 32-4 (B) to the right, connecting right channel 3 (A) 6 with right channel 3 (B) 9. Simultaneously, right valve core 32-4 (B) blocks right channel 1 (B) 7, preventing lubricating oil from entering outlet 3 (B) 32-7. When right valve core 32-4 (B) is pushed up and moves to the position of right pin 32-1 (B), right pin 32-1 (B) locks right valve core 32-4 (B) under the action of right spring 1 (B) 32-2. Lubricating oil enters B right channel 3 9, then enters B right channel 2 8, pushing C valve core 28 to move to the left, completing the oil inlet process.

[0071] See Figure 5 When valve core 28 moves to the left, it pushes the lubricating oil in cavity 3 40 into B left channel 2 20. The lubricating oil enters A left channel 3 18 through oil inlet pipe 1 2, then through A left channel 2 17, and then through A left channel 1 16 into outlet 6 35, where the lubricating oil is discharged and supplied to the lubrication point, completing the oil discharge process.

[0072] 2. Valve core B is blocked on the right side, and oil enters the inlet pipe.

[0073] like Figure 6As shown, B spool 27 is blocked at the right side, and the lubricating oil enters through inlet pipe 1 and inlet pipe 1 2. The entering lubricating oil enters B left passage 2 20 through B left passage 3 21, and pushes C spool 28 to move rightward, thus completing the oil inlet process.

[0074] Referring to Figure 7 , C spool 28 moves rightward, and pushes the lubricating oil in cavity 3 40 into B right passage 2 8, and then into B right passage 3 9. Since B spool is blocked at the right side, when oil enters through inlet pipe 2 3, B right spool 32-4 of outlet assembly 3 2 has been opened, thus connecting B right passage 3 9 and A right passage 3 6, and thus the lubricating oil enters A right passage 3 6, and then enters A right passage 2 5, and then enters 2 outlet 3 1 through A right passage 1 4, and then the lubricating oil is discharged to lubricate the lubricating point, thus completing the oil outlet process.

[0075] II. B spool is blocked at the left side, and other spools work normally

[0076] 1. B spool is blocked at the left side, and inlet pipe 1 is used for oil inlet

[0077] Figure 8-9 As shown, B spool 27 is blocked at the left side, and oil enters from inlet pipe 1. The lubricating oil enters A left passage 2 17 through inlet pipe 1 2 from main inlet 1, and pushes B spool 27 to move rightward. Since B spool 27 is blocked at the left side, it cannot be pushed. The system pressure rises due to the lack of passage, and the pressure of A left passage 3 18 rises. When the system pressure is greater than the elastic force of B left spring 2 36-5, B left spool 36-4 opens leftward, thus connecting A left passage 3 18 and B left passage 3 21, and cutting off the oil passage of B left passage 1 19, so that the lubricating oil cannot enter 7 outlet 36-7. When the clamping groove of B left spool 36-4 moves leftward to the position of B left top pin 36-1, B left top pin 36-1 is clamped by B left spring 1 36-2. The lubricating oil enters B left passage 2 20 through B left passage 3 21, and pushes C spool 28 to move rightward, thus completing the oil inlet process.

[0078] Referring to Figure 10 , C spool 28 moves rightward, and pushes the lubricating oil in cavity 3 40 into B right passage 2 8, and then into B right passage 3 9, and then enters A right passage 3 6 through inlet pipe 2 3, and then enters A right passage 2 5, and then enters 2 outlet 3 1 through A right passage 1 4, and then the lubricating oil is discharged to lubricate the lubricating point, thus completing the oil outlet process.

[0079] 2. B spool is blocked at the left side, and inlet pipe 2 is used for oil inlet

[0080] Figure 11As shown, B spool 27 is blocked at left side, lubricating oil flows from main inlet 1 through inlet pipe 2, enters A left passage 2 17, pushes A spool 26 to move to right, completes the oil inlet process.

[0081] Referring to Figure 12 , A spool 26 moves to right, pushes the lubricating oil in cavity 3 39 to enter B left passage 2 20, and then enters B left passage 3 21. Since B spool 27 is blocked at left side, when oil is fed through inlet pipe 1 2, A left passage 3 18 and B left passage 3 21 have been opened, thus lubricating oil enters A left passage 3 18 through B left passage 3 21, and then flows through A left passage 2 17 and A left passage 1 16, enters outlet 6 35, and then is discharged to lubrication points through pipes, completing the oil outlet process.

[0082] III. C spool is blocked at right side, and other spools work normally

[0083] 1. C spool is blocked at right side, and inlet pipe 2 feeds oil

[0084] As shown, C spool 28 is blocked at right side, lubricating oil flows from main inlet 1 through inlet pipe 2, enters C left passage 2 23, pushes D spool 29 to move to right, completes the oil inlet process. Figure 13-14

[0085] Referring to Figure 15 , D spool 29 moves to left, pushes the lubricating oil in cavity 4 41 to enter C left passage 2 23, and then enters B left passage 3 21 through inlet pipe 1 2, enters B left passage 2 20, and then enters B left passage 1 19, enters outlet 7 assembly 36 through 7 outlet 36-7, and then is discharged to lubrication points through pipes, completing the oil outlet process.

[0086] 2. C spool is blocked at right side, and inlet pipe 1 feeds oil

[0087] Figure 16 As shown, C spool 28 is blocked at right side, lubricating oil flows from main inlet 1 through inlet pipe 1 2, enters C left passage 2 23, pushes D spool 29 to move to right, completes the oil inlet process. ​

[0088] See Figure 17 When valve core 29 moves to the right, it pushes the lubricating oil in cavity 41 into right channel C2 11, and then into right channel C3 12. Since valve core 28 is blocked on the right side, right channel B3 9 and right channel C3 12 are already open when oil enters through inlet pipe 2 3. Therefore, the lubricating oil flows through right channel C3 12, into right channel B3 9, then into right channel B2 8, through right channel B1 7, into outlet assembly 32, and is discharged through outlet 32-7. The oil is then supplied to the lubrication points through the pipeline, completing the oil discharge process.

[0089] IV. Valve core C is blocked on the left side, while other valve cores are functioning normally.

[0090] 1. Valve core C is blocked on the left side, and oil enters the inlet pipe.

[0091] Figure 18-19 The diagram illustrates a scenario where valve core C 28 is blocked on the left side, with oil entering through inlet pipe 2. Lubricating oil enters from the main inlet 1 via inlet pipe 2 into left channel B 20, and then into left channel B 3 21. Because valve core C 28 is blocked on the left side, the lubricating oil cannot push it forward, causing the system pressure to rise. When the system pressure exceeds the elastic force of left spring C 2 37-5, left valve core C 37-4 moves to the left, opening left channel B 3 21 and left channel C 3 24. Simultaneously, as left valve core C 37-4 moves, it cuts off left channel C 22, preventing lubricating oil from entering outlet 8 37-7. As left valve core C 37-4 moves, when the slot on left valve core C 37-4 moves to the position of left top pin C 37-1, left top pin C 37-1, under the action of left spring C 1 37-2, jams left valve core C 37-4. Lubricating oil enters C left channel 3 24, flows through C left channel 2 23, and pushes valve core D 29 to move to the right, completing the oil inlet process.

[0092] See Figure 20 When valve core 29 moves to the right, it pushes the lubricating oil in cavity 41 into right channel 2 11, then through oil inlet pipe 2 3 into right channel 3 9, then through right channel 2 8 into right channel 1 7, and finally out through outlet 32-7. The oil is then supplied to the lubrication point through the pipeline to complete the oil discharge process.

[0093] 2. Valve core C is blocked on the left side, and oil inlet pipe 2 is blocked.

[0094] like Figure 21 As shown, valve core 28 of C is blocked on the left side. Lubricating oil enters right channel 11 of C from the main oil inlet 1 through oil inlet pipe 23, pushing valve core 29 of D to move to the left to complete the oil inlet process.

[0095] like Figure 22As shown, valve core 29 moves to the left, pushing the lubricating oil in cavity 41 into left channel 23. Because valve core 28 is blocked on the left side, when oil enters through inlet pipe 2, it opens left channel 21 and left channel 24, so the lubricating oil enters left channel 21 through left channel 24. It then enters left channel 19 through left channel 20, and finally exits through outlet 36-7, supplying oil to the lubrication points through the pipeline, completing the oil discharge process.

[0096] 5. Valve core D is blocked on the right side, while other valve cores are working normally.

[0097] 1. Valve core D is blocked on the right side, oil inlet pipe 2 is blocked.

[0098] Figure 23-24 This illustrates the scenario where valve core 29 (D) is blocked on the right side, and oil enters through inlet pipe 2 (3). Lubricating oil enters right channel 11 (C) from the main inlet 1 via inlet pipe 2 (3). Because valve core 29 is blocked on the right side, the lubricating oil cannot push it, causing the system pressure to rise. When the system pressure reaches a certain threshold exceeding the elastic force of right spring 2 (34-5), valve core 34-4 (D) moves to the right, opening right channel 3 (C) (12) and left return channel 15. Simultaneously, when valve core 34-4 (D) reaches the position of right top pin 34-1, right top pin 34-1, under the action of right spring 1 (34-2), blocks valve core 34-4 (D). At this point, valve core 34-4 (D) blocks right channel 13 (C), preventing lubricating oil from entering outlet 5 (34-7). The lubricating oil enters left return channel 15, pushing valve core 26 (A) to the right, completing the entire oil intake process.

[0099] like Figure 25 As shown, valve core 26 moves to the right, pushing the lubricating oil in cavity 38 into the right return channel 14, then into the oil inlet pipe 2, through left channel 3 24, into left channel 2 23, then into left channel 1 22, and the lubricating oil is discharged from outlet 8 37-7, and supplied to the lubrication point through the pipeline, completing the oil discharge process.

[0100] 2. Valve core D is blocked on the right side, and oil enters the inlet pipe.

[0101] like Figure 26 As shown, valve core 29 of D is blocked on the right side. Lubricating oil enters the right return channel 14 from the main oil inlet 1 through the oil inlet pipe 2, pushing valve core 26 of A to move to the left to complete the oil inlet process.

[0102] like Figure 27As shown, valve core 26 moves to the left, pushing the lubricating oil in cavity 38 into the left return channel 15. Because valve core D is blocked on the right side, when oil enters through oil inlet pipe 2 3, it opens right channel 3 12 and left return channel 15. Therefore, the lubricating oil enters right channel 3 12, then enters right channel 2 11, flows through right channel 1 10, and is discharged from outlet 4 33-7, completing the oil discharge process.

[0103] 6. Valve core D is blocked on the left side, while other valve cores are working normally.

[0104] 1. Valve core D is blocked on the left side, and oil enters the inlet pipe.

[0105] like Figure 28-29 As shown, valve core 29 (D) is blocked on the left side. Lubricating oil enters C left channel 3 (24) from the main inlet 1 through inlet pipe 1 (2), and then enters C left channel 2 (23). Because valve core 29 is blocked on the left side, the lubricating oil cannot push valve core 29, and the system pressure increases. When the system pressure reaches a certain threshold, exceeding the elastic force of D left spring 2 (30-5), D left valve core 30-4 moves to the left, opening the right return channel 14 and C left channel 3 (24). Simultaneously, when D left valve core 30-4 moves to the position of D left top pin 30-1, D left top pin 30-1, under the action of D left spring 1 (30-2), jams D left valve core 30-4, and simultaneously blocks D left channel 1 (25), preventing lubricating oil from exiting from outlet 1 (30-7). The lubricating oil enters right return channel 14, pushing valve core 26 (A) to the left, completing the oil inlet process.

[0106] See Figure 30 When valve core 26 moves to the left, it pushes the lubricating oil in cavity 38 into the left return channel 15, then into the oil inlet 3, flows through right channel 3 12, into right channel 2 11, then into right channel 10, and is discharged from outlet 4 33-7, completing the oil discharge process.

[0107] 2. Valve core D is blocked on the left side, and oil enters through the second oil inlet pipe.

[0108] like Figure 31 As shown, valve core 29 of D is blocked on the left side. Lubricating oil enters the left return channel 15 from the main oil inlet 1 through the oil inlet pipe 2 3, pushing valve core 26 of A to move to the right to complete the oil inlet process.

[0109] See Figure 32 When valve core 26 moves to the right, it pushes the lubricating oil in cavity 38 into the right return channel 14. Because valve core 29 is blocked on the left side, when oil enters through inlet 2, it has already opened the right return channel 14 and C left channel 3 24. Therefore, the lubricating oil enters C left channel 3 24, then enters C left channel 2 23, flows through C left channel 1 22, and is discharged from outlet 8 30-8, completing the oil discharge process.

[0110] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
