s4, a pressure-changing piston (12) in one end of a piston (9) extruding a coolant is extruded by a compression spring (13), a part of high-pressure coolant enters a space formed at the front end of a pressure-changing hole (901), meanwhile, a baffle I (121) blocks an oil suction channel (902), an oil drainage hole (123) in a baffle II (122) is communicated with an oil outlet (904), the internally sucked lubricating oil (20) is discharged from the oil outlet (904), at the moment, one end of the piston (9) sucking the coolant is reset by the spring (13), the pressure-changing piston (12) extrudes the high-pressure coolant, the baffle I (121) opens the oil suction channel (902), the baffle II (122) blocks the oil outlet (904), and the lubricating oil (20) is sucked into a cavity in the piston (9) through an oil pipe (14);
s5, the lubricating oil (20) discharged from the oil outlet (904) is accumulated in a space formed by the middle groove of the piston (9) and the cylinder (7), and when the storage amount of the lubricating oil (20) is excessive, the oil drain valve (21) is opened for draining oil.
