The purpose of the present invention is to be able to minimize wear, even when repeatedly coupling and separating in order to replenish a discharging device with a fluid, of a coupling portion between the discharging device and a replenishing device that is caused by particulate matter contained in the fluid. A discharging system (10) comprises a discharging device (20) that can discharge a fluid and a replenishing device (100) that can replenish the discharging device (2) with the fluid, and the system can supply the fluid from the replenishing device (100) side to the discharging device (20) side by coupling the devices by inserting a discharge-side coupler (80) provided on the discharging device (20) side into a replenish-side coupler (134) provided on the replenishing device (100) side. The clearance (d) formed between the discharge-side coupler (80) and the replenish-side coupler (134) is set on the basis of the particle size distribution of particulate matter that constitutes the fluid. |
