Detailed Description
Fig. 1 is a schematic structural diagram of the present invention, and a novel engine oil regulating valve is characterized by comprising a housing 1; an engine oil outlet 2 is formed in the left side of the shell 1, and the engine oil outlet 2 is communicated with a filtered engine oil cavity 3; the middle part of the filtered engine oil cavity 3 is provided with an engine oil filter 4; the left side of the oil filter 4 is communicated with a front oil filtering cavity 5; an oil hole I6 is formed in the left side of the oil cavity 5 of the engine before filtering, and a main oil duct oil inlet 7 is formed below the oil hole I; the first oil hole 6 is communicated with a cavity 8 to be leaked; a piston push rod 10 is arranged in the cavity 8 to be leaked, and a spring installation cavity 11 is arranged below the piston push rod; a spring 12 is arranged in the spring mounting cavity 11, and the left side of the spring mounting cavity is provided with a third oil hole 13.
Specifically, the third oil hole 13 is mainly used for removing redundant engine oil permeating into the spring mounting cavity 11, so that the spring mounting cavity 11 is prevented from forming a sealing cavity to block the downward movement of the piston push rod 10, and the normal operation of the whole piston push rod 10 is ensured.
According to another embodiment of the present invention, further comprising that the lower end of the piston rod 10 is connected to a spring 12; an ejector rod 15 is connected below the spring 12 through a mandrel 14.
According to the utility model discloses a further embodiment, further include, 14 lower extreme both sides of dabber are fixed with flange 16, are equipped with sealing washer 17 with ejector pin 15 junction.
According to the utility model discloses a further embodiment, it is further included, ejector pin 15 and flange 16 pass through threaded connection, the threaded connection has nut 18 outside ejector pin 15, nut 18 is located flange 16 below, comes the compressed length of adjusting spring 12 through nut 18 on the rotatory ejector pin 15 to adjust machine oil flow and pressure.
According to the utility model discloses a further embodiment, further include, piston rod 10 upper end is equipped with oilhole four 9, and the lower extreme left side is equipped with oilhole two 19.
According to the utility model discloses a further embodiment, further include, the oilhole four 9 link up with after-filtration oil chamber 3 mutually.
According to another embodiment of the present invention, it is further included that the oil filter 4 is welded inside the housing 1.
In the specific operation process, engine oil enters the engine oil cavity 5 before filtration from the oil inlet 7 of the main oil duct and then is divided into two paths: one path enters a to-be-leaked cavity 8 where the oil hole I6 is positioned, and the other path enters the oil filter 4. The engine oil in the engine oil filter 4 enters the filtered engine oil cavity 3 after being filtered, the filtered engine oil cavity 3 is communicated with the engine oil hole four 9, and the engine oil pressure directly acts on the piston push rod 10. When the filtered engine oil pressure is greater than the use requirement, namely the engine oil pressure acting on the piston push rod 10 is greater than the elastic force of the spring 12, the piston push rod 10 is pushed to move downwards, so that the first oil hole 6 and the second oil hole 19 are communicated, and the engine oil in the cavity 8 to be leaked, where the first oil hole 6 is located, is discharged. The larger the pressure of the oil hole four 9 is, the longer the moving stroke of the piston push rod 10 is, the larger the leakage area is, more engine oil flow before filtering is discharged, the flow of the engine oil entering the filtering is reduced, and the oil pressure of the oil hole four 9 is correspondingly reduced. On the contrary, when the oil pressure at the oil hole four 9 is too low, the pressure on the piston push rod 10 is smaller than the pressure of the spring 12, the piston push rod 10 moves upwards, the through area of the oil hole one 6 and the oil hole two 19 is gradually reduced, the oil leakage flow is reduced, and the oil entering the oil filter 4 is increased; the oil flow of the device increases the oil pressure at the oil hole four 9. The oil flow and pressure of the system are also stabilized until the oil pressure acting on the piston push rod 10 is balanced with the spring 12 pressure.
The foregoing description is intended to be illustrative, rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations, or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
