Abstract
Description
中空体を含む検出器であって、
この中空体内部において、ピストンが密閉した状態で摺動し、ピストンは中空体の入口を介して圧力を受けるように構成され、
中空体の入口が、前記圧力が内部に存在する囲いに連通し、
ピストンが、圧力の影響を受けて表示位置に向かって押されるように、圧力が限界に達し又は限界を越えたときにピストンを解放するのに適した限界保持手段により、圧力に抗して所定の位置に保持され、
ピストンが、限界保持手段に抗して押されることができるように、中空体の入口から突出するピンに固定される、
検出器を提供する。
Claims (5)
- ショックアブソーバ等のための超過圧力及び底付きの検出器であって、
中空体(11)を含み、
この中空体内部において、ピストン(14)が密閉した状態で摺動し、ピストンは中空体の入口(12)を介して圧力を受けるように構成され、
中空体の入口が、前記圧力が内部に存在する囲いと連通し、
ピストンが、圧力の影響を受けて表示位置に向かって押されるように、圧力が限界に達し又は限界を越えたときにピストンを解放するのに適した限界保持手段(21)により、圧力に抗して所定の位置に保持され、
