ABSTRACT:
The invention provides an improved drain valve for dew condensation in an air chiller unit mounted on an aircraft. The drain valve160attached to a drain of a drain pan in an air chiller unit is equipped with a valve seat member162having an opening162aat the center and a valve member164disposed to contact the lower surface of the valve seat member162. The valve member164is made of thin silicon rubber, and arms164bcreated by slits formed thereto support a valve means164ewith extremely small spring constant. While the air chiller unit is operating, the valve means164eis air tightly attached to the opening162aof the valve seat by negative pressure, closing the drain valve. When the operation stops and dew drops gather on the valve means164e, the valve means164eis displaced by the weight and the valve is opened. When there are no dew drops, the valve is closed to prevent moisture from entering.
