[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figures 1 to 3 As shown, this embodiment includes a pump base 1, a pump housing 2, a nozzle base 3 and a coil regulator 4. A connector 21 is formed at the front end of the pump base 1. The nozzle base 3 is fixedly connected to the outer end of the connector 21. An oil inlet 11 and an oil outlet 12 are respectively provided at the bottom end of the pump base 1. The outer ends of the oil inlet 11 and the oil outlet 12 are sealed with a sealing plug 18, and the sealing plug 18 is detachable. A reflux hole 13 is provided at the upper end of the pump base 1. A coil regulator 4 is fixedly installed at the upper end of the pump base 1. The coil regulator 4 includes an adjusting rod 41. An adjusting head 42 is installed at the bottom of the adjusting rod 41. The adjusting head 42 extends into the reflux hole 13 and the outer wall of the adjusting head 42 fits with the inner wall of the reflux hole 13. The section rod 41 is controlled by the coil regulator 4 to move in the vertical direction. The adjusting rod 41 drives the adjusting head 42 to move in the vertical direction in the return hole 13. A through valve hole 14 is provided inside the pump seat 1, and a connecting hole 131 is provided in the return hole 13. The connecting hole 131 is connected to the valve hole 14. The first piston valve 5 and the second piston valve 6 are sealed on both sides of the valve hole 14. A valve convex body 15 is formed on the outside of the valve hole 14 on one side of the first piston valve 5. A through hole 16 is provided on the valve convex body 15. An oil return channel 22 is formed on the outside of the pump housing 2. The through hole 16 is connected to the oil return channel 22, and the other side of the oil return channel 22 is connected to the nozzle seat 3.

[0020] To elaborate further, Figures 1 to 4 As shown, a filter 7 and an eccentric gear assembly 8 are installed inside the pump casing 2, a bearing seat 17 is formed in the center of the pump seat 1, an oil pump bearing 9 is installed inside the bearing seat 17, a pump shaft 10 is passed through and fixed in the center of the pump seat 1, and the eccentric gear assembly 8 and the oil pump bearing 9 are respectively sleeved on both ends of the pump shaft 10.

[0021] Specifically, when the regulating head 42 is located at the bottom of the reflux hole 13, the regulating head 42 closes the connecting hole 131 to generate pressure to push the piston in the first piston valve 5 to the side to generate pressure for the oil to flow out from the oil outlet 12 and burn. When the regulating head 42 is not in contact with the bottom of the reflux hole 13, the connecting hole 131 is connected to the valve hole 14, and the oil refluxes in the pump seat 1, which can prevent the pump shaft 10 from idling and play a lubricating role.
