Abstract
A fluid adjusting device is installed in a valve unit so as to control the volume or pressure of the fluid passing through the valve unit. The fluid adjusting device includes three parts retractably connected to each other and holes are defined through each of the three parts. By expanding or retracting the three parts, the holes can be exposed or hidden to adjust the volume or pressure of the fluid passing through the valve unit.
