PURPOSE: A sudden pressure change preventing booster is provided to minimize the vortex generated in a vacuum space by installing an air damper in a control valve of a booster. CONSTITUTION: A sudden pressure change preventing booster is composed of a control valve(2), an air damper(10), and a chamber(6). The control valve makes the atmospheric pressure flowed into a vacuum space by connecting between a vacuum space and an atmospheric space. The air damper divides the atmospheric pressure inflow space of the control valve and keeps the inflow of the atmospheric pressure. A negative pressure chamber and a variable pressure chamber are formed by dividing the chamber with a diaphragm. |
