PROBLEM TO BE SOLVED: To properly supply a drive force to an engine by compressed air, in a piston reciprocation-type air compressor.SOLUTION: A compressed air utilization device comprises: an air compressor 10 having a first electromagnetic valve 17 for opening and closing a clearance between a first port 15 and a cylinder 13, and a second electromagnetic valve 18 for opening and closing a clearance between a second port 16 and the cylinder 13; a motion decision part 71 for deciding whether or not to perform a compressed-air accumulation motion or a drive force supply motion; a flow passage setting part 72 for setting a flow passage for supplying compressed air to the second port 16 when the drive force supply motion is performed; and an electromagnetic valve control part 73 for controlling the first electromagnetic valve 17 to a valve-opened state and the second electromagnetic valve 18 to a valve-closed state in a piston ascending stroke when the drive force supply motion is performed, and controlling the first electromagnetic valve 17 to the valve-closed state and the second electromagnetic valve 18 to the valve-opened state in a piston descending stroke.SELECTED DRAWING: Figure 1

    【課題】ピストンを往復運動させる形式のエアコンプレッサにおいて、圧縮空気により適切にエンジンに駆動力を供給できるようにする。【解決手段】第1ポート15とシリンダ13との間を開閉する第1電磁弁17と、第2ポート16とシリンダ13との間を開閉する第2電磁弁18と、を備えるエアコンプレッサ10と、圧縮空気蓄積動作を実行させるか、又は、駆動力供給動作を実行させるかを決定する動作決定部71と、駆動力供給動作を実行させる場合には、圧縮空気を第2ポート16に供給させるための流路を設定する流路設定部72と、駆動力供給動作を実行させる場合には、ピストン上昇行程において、第1電磁弁17を開弁状態且つ第2電磁弁18を閉弁状態にするように制御し、ピストン下降行程において、第1電磁弁17を閉弁状態且つ第2電磁弁18を開弁状態にするように制御する電磁弁制御部73と、を備えるようにする。【選択図】図1
