Txoj kev xuas hluav taws xob: lub flywheel tsav lub crank qib zog, thiab lub crank nyob rau hauv lub crank rocker mechanism yog tus tswvcuab active, uas tsav lub rocker mus ua viav vias, thiab lub rocker thiab lub ratchet yog coaxial, li hloov cov kev sib nrauj reciprocating viav vias ntawm lub rocker rau hauv ib seem ntawm kev sib tw ntawm ratchet, lub ratchet Nws coincides nrog lub hauv paus ntawm txoj kab ntawm cov menyuam, thiab thaum kawg tus nqi ntawm daim ntawv xa tuaj rau qhov chaw ua haujlwm los ntawm kev nias ntawm tus menyuam tus ncej.
