- the first position detection sensor 70a and the second position detection sensor 70b detect the position of the first piston 44 has been described.
- the first position detection sensor 70a is inserted into the groove 68 of the second cylinder 16.
- the permanent magnet 72 is attached to the second piston 46, and the position of the second piston 46 is detected by the first position detection sensor 70a and the second position detection sensor 70b, Of course, the same effect can be obtained.
- the center body 12 is interposed between the first chamber 34 and the second chamber 36, and the first chamber 34 distal to the center body 12 has a first end in the A1 direction.
- One cover member 38 is disposed, and a second cover member 40 is disposed at the end of the second chamber 36 in the A2 direction distal from the center body 12.
- the first piston 44 is displaced in the first chamber 34 without contacting the center body 12 and the first cover member 38, and the second piston 46 is in contact with the center body 12 and the second cover member 40. Without moving, the inside of the second chamber 36 is displaced. Accordingly, when the fluid is supplied to or discharged from the first pressure increasing chamber 34a, the second pressure increasing chamber 36a, the first driving chamber 34b, and the second driving chamber 36b, the first piston 44 and the second piston 46 can be moved smoothly.

Abstract
Description
本実施形態に係る増圧装置10は、図1~図5に示すように、センタボディ12の一端側(A1方向側)に第1シリンダ14が連設されると共に、他端側(A2方向側)に第2シリンダ16が連設された2連式のシリンダ構造を有する。従って、増圧装置10では、A1方向からA2方向に向かって、第1シリンダ14、センタボディ12及び第2シリンダ16の順に連設されている。なお、第1シリンダ14、センタボディ12及び第2シリンダ16の外周面は、略面一に形成されている。
以上のように構成される増圧装置10の動作について、図7及び図8を参照しながら説明する。この動作説明では、必要に応じて、図1~図6も参照しながら説明する。なお、図7及び図8では、説明の便宜上、増圧装置10の断面形状を模式化且つデフォルメして図示していることに留意する。
以上説明したように、本実施形態に係る増圧装置10によれば、従来の機械的な機構によるピストンの駆動機構に代えて、第1位置検出センサ70a及び第2位置検出センサ70bの検出結果に基づく電気的な方向制御により第1ピストン44、ピストンロッド42及び第2ピストン46をA1方向及びA2方向に駆動させる。これにより、第1ピストン44、ピストンロッド42及び第2ピストン46の駆動機構が簡素化され、増圧装置10の内部構造を単純且つ簡素なものとすることができる。
