Example Embodiment
[0011] Specific embodiment 1: This embodiment will be described with reference to FIGS. 1-10. The hydraulic transformer of this embodiment includes a front valve plate 1, a hydraulic transformer housing 2, an oil path transition block 3, a bearing 4, a bearing seat 5, an end cover 6 and The main shaft 7; the hydraulic transformer also includes a rear valve plate 8, a hydraulic cylinder 9 and a rack 10, the rear valve plate 8 is installed in the hydraulic transformer housing 2, and the small diameter end face 8-1 of the rear valve plate 8 The front valve plate 1 arranged on the outside of the hydraulic transformer housing 2 is fixed by a pin. The outer wall of the large-diameter end face 8-5 of the rear valve plate 8 is machined with teeth in the circumferential direction. The hydraulic cylinder 9 is made of a hydraulic cylinder body 9. -1 and two pistons 9-2, the rack 10 is installed in the hydraulic cylinder 9-1, the two ends of the rack 10 are fixed with the two pistons 9-2 inst...
Example Embodiment
[0012] Second embodiment: This embodiment will be described with reference to Figs. 1, 8 and 9. The high pressure oil hole A1 of the oil passage transition block 3 of this embodiment is a high pressure oil hole inclined in the direction of the rear valve plate 8. The oil passage The load oil hole B1 and the oil return tank oil hole C1 of the transition block 3 are both L-shaped. The other components and connection relationships are the same as in the first embodiment.
Example Embodiment
[0013] Specific implementation mode three: combination Figure 5 with Figure 6 To illustrate this embodiment, the high-pressure passage A3, the load passage B3 and the oil return tank passage C3 on the rear valve plate 8 of this embodiment are all composed of an axial straight passage 8-3 and an oblique passage 8-4. The axial straight passage 8-3 is located on the small-diameter end surface 8-1 of the rear valve plate 8 to facilitate oil output. The other components and connection relationships are the same as in the first embodiment.
