Description
チェーン及びベルトテンショナでは、ピストンは、スプリングまたはスプリングと油圧(hydraulic pressure)によってそのハウジングから圧迫される。ハウジングとピストンとの間のボア内に形成された流体チャンバと加圧流体源との間のテンショナにチェックバルブが追加されて、流体チャンバからの油圧流体の逆流を防止する。ピストンとボアとの間の隙間を通る漏洩率は、補充流体が沈下または停止するにつれて、ピストンの後退を可能にする。漏洩率が増加するにつれて、ピストンの後退に対する抵抗が減少し、漏洩率が減少するにつれて、ピストンの後退に対する抵抗が増加する。チェーン荷重が急増するかまたは流体圧力の損失が存在するときに、プランジャの後退が起こり、プランジャの後退が過度な場合、チェーン制御の損失、エンジン時間の損失または他の望ましくない影響が生じる。したがって、ピストンの後退量を制限することが望ましい。
