Rau kev tsim kev suav, siv cov kab hluav taws xob sib faib los ntawm qhov ntsuas kub ntawm lub taub dej mus rau qhov chaw tsim khoom kub kub (tsis yog qhov ntsuas kub ntawm qhov chaw txhaj tshuaj). Kev ntsuas kub hauv qhov no qhia tau hais tias cov roj txhaj tshuaj sai tau txais qhov kub ntawm cov kua dej hauv lub annulus thaum lub qhov dej nyob hauv ib txwm ua haujlwm (tom qab tshem tawm) yog li nws yuav yog qhov yuam kev los kwv yees lub valve tsim qhov kub thiab txias sib npaug ntawm linear kub faib. los ntawm lub reservoir kub mus rau saum npoo gas txhaj kub. Rau kev daws teeb meem kev tshuaj xyuas, qhov ntsuas kub zoo sib npaug ntawm qhov ntsuas kub hauv lub annulus ntawm lub valve qhov tob tuaj yeem siv vim, raws li tau hais dhau los, cov roj txhaj tshuaj tuaj yeem suav tias yog qhov kub ntawm qhov ntawd.
