Ukudluliselwa kwesikhathiiwumshini wokulawula osebenzisa isimiso sikagesi noma isimiso somshini ukuze sifinyelele ukulawula ukubambezeleka kwesikhathi. Inezinhlobo eziningi, njengohlobo lwe-air damping, uhlobo lukagesi kanye nohlobo lwe-electronic. Ukudluliselwa kwesikhathi kungahlukaniswa ngezinhlobo ezimbili: uhlobo lokulibaziseka kwesikhathi esinikwe amandla kanye nohlobo lokulibaziseka kwesikhathi sokuvala amandla. Ukudlulisa isikhathi esimanziswe komoya kunebanga elikhulu lokulibaziseka (0.4 ~ 60s kanye no-0.4 ~ 180s), kulula ngesakhiwo, kodwa kunembe kancane.
Uma ikhoyili inikwa amandla, izikhali kanye namaphalethi kukhangwa umongo futhi kwehle ngokuphazima kweso, okwenza ukuthi isenzo esisheshayo sivuleke noma sivale. Kodwa induku ye-piston kanye ne-lever ayikwazi ukulandela i-armature kanye ne-drop, ngoba umkhawulo ongaphezulu we-piston rod uxhunywe kulwelwesi lwenjoloba ekamelweni lomoya, lapho induku ye-piston ekukhululweni kwentwasahlobo iqala ukwehla, ulwelwesi lwenjoloba phansi kwe-concave, igumbi lomoya ngaphezu komoya liba lincane futhi induku ye-piston imanzi futhi kancane kancane iwe. Ngemva kwesikhathi esithile, induku ye-piston yehlela endaweni ethile, izocindezela isenzo sokuxhumana sokubambezeleka nge-lever, ukuze ukuxhumana kwekhefu okuguquguqukayo kuvaliwe, ukuthintana okuguquguqukayo kuvaliwe. Kusukela kukhoyili enikwe amandla kuye kothintana naye ukubambezeleka kwesikhathi ukuze uqedele isenzo, lesi sikhathi isikhathi sokulibaziseka kokudluliselwa. Ubude besikhathi sokulibaziseka bungashintshwa ngokulungisa usayizi wembobo yokungena yegumbi lomoya ngesikulufu. Ngemva kokuba ikhoyili ehehayo isuswe amandla, i-relay ilulama ngesenzo somthombo wokubuyisela. Umoya ukhishwa ngokushesha ngembobo yokukhipha umoya.
