The spring 8 is sleeved with a piston assembly 10, and the top of the shell 1 is connected to a piston stop plug 11. A sealing gasket is connected between the shell 1 and the piston stop plug 11. The piston stop plug 11 is spirally connected to an adjusting screw 12, and a locking nut 13 is outer-mounted on the adjusting screw 12. The bottom end of the adjusting screw 12 is connected to the piston assembly 10, and the movement of the piston assembly 10 is adjusted by rotating the adjusting screw 12. The outer wall of the shell 1 is provided with a first oil outlet 101 and a second oil outlet 102, and the first oil outlet 101 and the second oil outlet 102 are both connected to the oil storage pipe 7.

[0023] The bottom end of the oil filling pipe 2 is connected to an adapter 14 for adapting to various mechanical equipment. The oil filling pipe 2 is provided with an oil inlet hole 15 near the bottom end.

[0024] A first rubber sealing ring 16 and a first iron sealing ring 17 are sequentially sleeved outside the plunger 4 between the oil pan 5 and the oil filling pipe 2 from top to bottom to ensure that the oil will not leak.

[0025] A second iron sealing ring 18 is sleeved between the oil filling pipe 2 and the adapter 14 , and a second rubber sealing ring 19 is sleeved on the outer sleeve of the plunger 4 . The second rubber sealing ring 19 is located at the top of the oil pan 5 .

[0026] A sealing ball 601 is provided at the bottom end of the oil delivery pipe 6. The oil delivery pipe 6 includes a vertical pipe 602, a first inclined pipe 603 and a second inclined pipe 604.

The oil enters the oil pipe 6 through the oil inlet hole 15 and is transported upward. The oil pressure is relatively large, pushing the plunger 4 upward, and then enters the oil pan 5, and then enters the oil storage pipe 7 through the oil pipe 6. Finally, the oil enters the oil outlet pipe from the first oil outlet hole 101 or the second oil outlet hole 102 and is transported out. During the transportation process, the oil pressure decreases, resulting in a continuous decrease in the oil output rate. At this time, the piston assembly 10 is driven downward by rotating the adjusting screw 12, compressing the spring 8, causing the spring 8 to deform and restore the elastic force, so that the oil outlet pressure returns to normal.
