When the f force at the oil discharge portion 342 is excessively large, the pressure of the fluid flows into the valve 351 ' via the first communication portion 352 and pushes the partition wall 514 of the valve block ,, so that the valve block 5 丨 overcomes the yellowing 52 When the elastic force is moved upward, when the pressure relief hole 515 of the valve block 51 corresponds to the second communication section 353, the fluid is cut into the oil guiding main passage 63 of the oil guiding seat 6 by the pressure releasing outlet of the second communicating section (5). The TM (4) mouth is discharged, wherein the angle is sprayed toward the power gear 4 ιι, and thus the power tooth 11 is given a pushing force that rotates in the working direction, and the second fuel channel 68 is also sprayed at an oblique angle. The driven gears are still geared to the direction of the workmanship:: Yuan: 2 directly or indirectly driven gears - heart: two: V force, therefore, at this time the power unit - push is also used Come, the drive gear 4ll, 4ni "power load can be reduced, this new type does have reduced power, the power load will be reduced, so the purpose of this new type in the end of the heart of the 533 is to 11 M288658 oil drain 'because the valve block 51 is on the shaft In the process of displacement, the adjacent closed end 355 (four) body may infiltrate to the side of the adjacent open end 354 via the outer peripheral edge of the valve wall 511. In order to prevent the portion where the spring 52 is mounted from being filled by the leaked fluid, the spring 52 is affected. The normal compression, the oil drain hole 533 is arranged to prevent fluid from accumulating between the seat 53 and the valve seat 51. In addition, the fuel injection ports 67, 68 on the oil guide seat 6 of the present invention can also be provided individually, and the gear Unit 41 can also be single 'utilized with a single Road and a single gear oil can also achieve the desired effect.
