Claims

[Scope of utility model registration request]

A large piston, a small piston whose one surface is connected to one surface of the large piston, and the large piston are slidably fitted together, and the cylinder chamber on the other surface of the large piston lubricates the oil supply area. The small piston is slidably fitted into a large cylinder that communicates with the suction portion of the pump for supplying oil, and a cylinder chamber on the other side of the small piston communicates with a supply pipe that pumps lubricating oil. a small cylinder, a through hole formed in a position that can be closed by the small piston of the small cylinder, and piping that communicates the cylinder chamber of the small cylinder and the cylinder chamber of the large cylinder through the through hole. and by selecting a ratio of the cross-sectional areas of the large piston and the small piston to a predetermined ratio, when the amount of lubricating oil filled in the cylinder chamber of the large cylinder is more than a predetermined amount, the through hole is blocked by the small piston to prevent lubricating oil from being filled into the cylinder chamber of the large cylinder, and when the amount of lubricating oil filled in the cylinder chamber of the large cylinder becomes less than a predetermined amount, the A centralized filling device in a centralized lubrication/oil supply system, wherein a through hole is opened and lubricating oil is filled into a cylinder chamber of a large cylinder via the piping.
