下表は4台の携帯型エアコンプレッサが本考案に係る自然吸気シリンダーを使用し、12Vの電圧条件下で205/60R16 タイヤを0〜250kPa空気入れするテストデータテーブルである。
The table below is a test data table where four portable air compressors use a naturally aspirated cylinder according to the present invention and inflate 205 / 60R16 tires at 0 to 250 kPa under a voltage condition of 12V.
上表からわかるように、4台のサンプルは最大動作電流が6.6〜6.9Aであり、タイヤの空気入れ時間が最速で5分57秒であり、最遅で6分23秒である。それにより、従来技術の携帯型エアコンプレッサに比べて、最大動作電流が低く、タイヤの空気入れ時間が短く、さらにエアコンプレッサの動作電力が小さい。本考案の構造の改良によれば、低圧縮比シリンダーの設計を使用しても、低電流、急速空気入れの技術的効果を実現することができる。 As can be seen from the table above, the four samples have a maximum operating current of 6.6 to 6.9 A, and the tire inflating time is 5 minutes 57 seconds at the fastest and 6 minutes 23 seconds at the slowest.
