WIPO Patent Application WO/2022/131425
Kind Code:
A1
Abstract:
The present invention relates to a dryer cartridge capable of improving a cleaning effect of compressed air by filtering out moisture, oil, and foreign substances contained in the compressed air in multiple stages inside the cartridge, and capable of collecting oil at the bottom thereof. To this end, in the present invention, an oil collection type air dryer cartridge for a commercial vehicle comprises: a housing having an upper open end and a closed bottom surface at the other end; a cartridge container part located inside the housing and having a desiccant stored therein; and an oil-collecting support for collecting oil separated from compressed air flowing into the cartridge container part. In addition, the present invention is characterized in that in forming a narrow compressed air flow path between a cartridge body and a cartridge housing, a collision member is formed that is a pre-filtering member capable of primarily filtering out oil and the like between the cartridge body and the housing, thereby improving the performance of a filter cartridge of removing oil and moisture.
