A pump unit 1 with a depressurizing mechanism of a centralized lubricating oil system is installed on the floor near this machine. As the pump unit 1, for example, a commercially available product such as SHOWA LCB1 type pump unit can be used. This product is equipped with a gear pump 4 for driving a motor 3 which is turned on and off at a set time by an AC timer or an IC timer on a lubricating oil tank 2 and a depressurizing mechanism 5. When the rotation of the pump 4 is stopped, the depressurizing mechanism 5 communicates a supply pipe line 6 described later with a return pipe line 7 to open the tank into the tank for depressurization. The depressurization mechanism is communicated with the positive displacement distributor 8 by the supply line 6, and the positive displacement distributor 8 is of the same SHOWA first-advance type DPB type or later-exposure type.
A commercially available distributor such as the DSA type can be used. The DPB type pushes up the plunger against the force of the spring by the oil pressure sent from the pump unit 1 and discharges the oil in the cylinder to the branch pipe 9. Then, the rotation of the pump is stopped, the pressure in the supply pipe 6 is lowered by the depressurizing mechanism 5, the plunger is lowered by the force of the spring, and the oil accumulated under the plunger is placed in the cylinder through the hole of the plunger. It is a thing. Further, the DSA type pushes up the piston 12 against the force of the spring by the oil pressure sent from the pump unit, and collects the oil in the cylinder. Next, when the pressure inside the supply pipe 6 is lowered by the pressure release mechanism 5, the piston is pushed down by the spring pressure and the oil in the cylinder is discharged to the branch pipe 9.
