Lub caij nplooj ntoos hlav-loaded hluav taws xob tiv tauj pins yog cov khoom siv kho tshuab siv los ua kev sib txuas hluav taws xob ntawm ob qhov sib txuas nrog lub zog tshwj xeeb los xyuas kom muaj kev sib txuas ruaj khov thiab ruaj khov.
Lawv muaj ib lub thoob los yog vaj tse uas muaj lub caij nplooj ntoos hlav thiab ib tug conductive tus pin los yog plunger. Raws li ob qhov mating tuaj ua ke, lub caij nplooj ntoos hlav compresses, thawb tus pin tawm tsam ntawm qhov chaw mating thiab tsim kom muaj kev sib txuas hluav taws xob.
Thaum cov mating qhov sib cais, lub caij nplooj ntoos hlav nthuav tawm thiab rub tus pin rov qab, tiv thaiv kev puas tsuaj rau qhov chaw sib cuag. Cov pins no feem ntau siv rau ntau yam kev lag luam, suav nrog tsheb, aerospace, thiab kev sib txuas lus, qhov twg muaj kev ntseeg siab thiab ua haujlwm zoo ib yam yog qhov tseem ceeb.
