Abstract

PURPOSE: To dispense with a special type spring as well as to simplify the constitution of an air conditioning unit by installing more than one screens among each of which springs are inserted.
CONSTITUTION: Since in a low pressure range the deformation of a spring 7 is larger than that of a spring 9, amounts of movement of screens 6 and 8 to a shaft 2 are different, which varies the opening area of a ventilation flue 11. As the air pressure increases, the difference in the deformation of springs 7 and 9 increases, and a screen 8 for the low pressure contacts a screen 6 for the medium and high pressure, completely closing the ventilation flue 11. At this time, ventilation is allowed through a ventilation flue 12 located between a scrren 6 and a partition member 10. As the air pressure is increased further, both screens 6 and 8 move as one body, pressing the spring 7 only. Accordingly, only the ventilation flue 12 varies its opening area depending upon the air pressure.
