向って上昇する。Conventionally, this type of compressed air source device was
There is one described in Japanese Patent No. 104786. This compressed air source device dries high-pressure compressed air compressed by an air compressor through an air dryer containing a renewable adsorbent, and then supplies this dry compressed air to an air storage tank. The stored dry compressed air is consumed in a pneumatic circuit such as a vehicle's air brake circuit. The compressed air source device includes a governor device that monitors the pressure in the air storage tank, a purge storage tank that takes in and stores a portion of dry air from the air dryer, and a regeneration device that is controlled by the governor device. It is integrated with
The governor device generates an unload command when the pressure in the air storage tank rises to a predetermined first level, and the pressure rises to a second level.
When the level drops to , the unload command is canceled. In response to this unload command, the air compressor stops discharging compressed air, and the regeneration device operates. When the regenerator is operated, the dry air in the purge storage tank flows back through the air dryer and then flows out into the atmosphere to regenerate the adsorbent. When the pressure in the air storage tank drops to the second level and the unload signal is released, the air compression device resumes operation and starts discharging compressed air, and the pressure in the air storage tank returns to the first level. rise towards.

という問題があった。In this way, the air compressor repeats the loading and unloading cycle, regenerating the adsorbent in the air dryer during the unloading cycle, so that the air reservoir always has
The compressed air with low humidity is stored, but the compressed air discharged by the air compressor at the beginning of loading is at low pressure, and the inside of the purge storage tank is at atmospheric pressure at the beginning of loading, so the purge storage tank is , this low-pressure compressed air flows in, and the pressure inside the purge storage tank is low at first, but then it becomes high pressure, so the humidity inside the purge storage tank increases, and the humidity of the compressed air supplied to the air storage tank is increased. The problem was that it could not be lowered.

切換弁８が介装されている。In FIG. 1, 1 is an air compression device. Reference numeral 2 denotes a compressed air drying device, which, as shown in FIG. A check valve device 3 provided on the lid 33 and provided at an opening of the lid 33
4, a purge storage tank 4 that communicates with the inside of the air dryer 3 through a throttle 35, and a regenerator 5 that is integrally provided at the bottom of the main body 31 and that communicates with and shuts off the inside of the main body 31 and the atmosphere. This compressed air drying device 2 introduces compressed air from the air compressor 1 through an inlet 36 formed in a main body 31, and transfers the introduced compressed air to a filter device 37, an adsorbent 3
2 to the opening of the lid 33 and flow into the purge storage tank 4. The regenerator 5 is a drain valve, and its valve body 51 is driven by a pneumatic signal introduced through a control port 51, which will be described later, to open the valve. 6 is an air storage tank, and the purge storage tank 4 is passed through a pipe 7.
A switching valve 8 is interposed in the cough line 7 .

弁する。Reference numeral 9 denotes a governor device which generates an unload command (air pressure signal) when the pressure within the air storage tank 6 rises to a predetermined first level, and when it falls to a second level lower than the first level. Cancel the unload command. This unloading command is supplied to the unloading device (not shown) of the air compressor 1, the control port 52 of the regenerator 5, and the switching valve 8 through the conduit 7. The switching valve 8 closes when receiving an unload command, and opens when the unload signal disappears.

を再生したのち大気中に流する。In this configuration, when an unload command is issued, the switching valve 8 is closed to shut off the air storage tank 6 and the purge storage tank 4, and in this state, the regenerator 5 is opened to compress and dry the purge storage tank 4. Air flows back through the air dryer 3 and the adsorbent 31
is regenerated and then released into the atmosphere.

流入できず、空気貯槽１の圧力を越えるとパージ貯槽４
に流入し始める。When the pressure inside the air storage tank 6 decreases and the unload signal disappears, the air compressor 1 starts discharging compressed air, but at the same time, the switching valve 8 opens and the air storage tank 6 and purge storage tank 4 communicate with each other. The pressure in purge reservoir 4 rises to the pressure level in air reservoir 6. Therefore, until the pressure of the compressed air discharged by the air compressor 1 rises and the pressure inside the air dryer 3 becomes greater than the pressure in the air storage tank 6, it cannot flow into the purge storage tank 4, and the air cannot flow into the air storage tank 6. purge storage tank 4 when the pressure exceeds
begins to flow into
従って、ロード初期の前記した低圧の圧縮空気はパージ
貯槽４内に流入しないので、空気貯槽６内に貯留する圧
縮空気は低湿度なものとなる。Therefore, since the aforementioned low-pressure compressed air at the initial stage of loading does not flow into the purge storage tank 4, the compressed air stored in the air storage tank 6 has low humidity.
また、この後、パージ貯槽４内に流入してゆく空気は比
較的高い圧力で吸着剤３２により乾燥されるので乾燥（

乾燥度の高い圧縮空気を貯溜することができる。As explained above, this invention is configured to introduce the pressure of the air storage tank into the purge storage tank at the start of the load cycle, so that the air compressor prevents the low-pressure compressed air discharged at the start of the load from flowing into the purge storage tank. The air storage tank has lower humidity than before.
Highly dry compressed air can be stored.
