Structure and operation principles
The figure below is a structural chart.
T1 and T2 are containers where the absorbent was filled, T1 dehumidifies air now, and T2 is assumed the reproduction. The
damp atmosphere enters adsorption column T1 through 5-port solenoid valve. The air dehumidified here goes out of check
valve CV1 to street OUT. A part of dry air which passed orifice O2 is decompressed and enters adsorption column T2 because
check valve CV2 at this time shuts. The moisture included in the absorbent is detached, and, it becomes dampness air, and it is
discharged into atmosphere through 5-port solenoid valve and 2-port solenoid valve. Next, adsorption column T1 reproduces,
adsorption column T2 enters the state of adsorption if 5-port solenoid valve is switched, and continuously steady by this repetition
dry air is obtained.
The solenoid valve has been switched with the timer (switching device) which combines the motor, the cam, and the limit
switch. 2-port solenoid valve is used to prevent the pulse caused at the switch of the adsorption column. That is, when
reproducing, the pulse is caused in the flow of air in having switched under such a condition because it is decompressed though
adsorbing it is the pressurizing under. Therefore, 5-port solenoid valve shuts 2-port solenoid valve before the switch, the
adsorption column is made this pressure, and the pulse is reduced.
