Izimpawu zePiston ziyizinto ezibalulekile embonini yezimoto, ikakhulukazi endaweni yezinto zokuvala injoloba ezisetshenziswa ezinhlelweni ze-hydraulic. Lezi zimpawu zidlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kwezinto ezahlukahlukene zezimoto, kufaka phakathi amasilinda, amaphampu nama-valve. Omunye wemisebenzi eyinhloko yezimpawu ze-piston ukuvimbela ukuvuza koketshezi ngaphakathi kohlelo lwe-hydraulic. Ngezinhlamvu
