Thermostat ni ubwoko bwubushakashatsi bugenzura ubushyuhe bwikora, mubisanzwe burimo ibice byerekana ubushyuhe, mugukwirakwiza cyangwa kugabanuka kugirango ufungure kandi uzimye urujya n'uruza rwamazi akonje, ni ukuvuga, guhita uhindura amazi mumirasire ukurikije ubushyuhe bwubukonje amazi, hindura uruzinduko rwamazi yo gukonjesha, kugirango uhindure sisitemu yo gukonjesha ubushobozi bwo gukwirakwiza.
Moteri nyamukuru thermostat ni ibishashara byo mu bwoko bwa thermostat, bigenzurwa na paraffine imbere binyuze mu ihame ryo kwagura ubushyuhe no kugabanuka gukonje kugirango igenzure ubukonje bukonje. Iyo ubushyuhe bukonje buri munsi yagaciro kagenwe, paraffine itunganijwe mumibiri yubushyuhe bwa thermostat irakomeye, valve ya thermostat munsi yimvura kugirango ifunge umuyoboro uri hagati ya moteri na radiator, ibicurane binyuze mumazi ya pompe kugeza garuka kuri moteri, moteri ntoya. Iyo ubushyuhe bwa coolant bugeze ku giciro cyagenwe, paraffine itangira gushonga kandi buhoro buhoro ihinduka amazi, kandi ijwi ryiyongera kandi rigakanda kuri rubber kugirango rigabanuke. Muri icyo gihe, umuyoboro wa reberi uragabanuka kandi ugatera hejuru hejuru ku nkoni. Inkoni yo gusunika ifite hasi kumanuka kuri valve kugirango ifungure. Muri iki gihe, ibicurane bitembera muri radiatori na valve ya thermostat, hanyuma bigasubira kuri moteri binyuze muri pompe y'amazi kugirango bizenguruke. Hafi ya thermostat itunganijwe mumazi asohora amazi yumutwe wa silinderi, ifite ibyiza byuburyo bworoshye kandi byoroshye gusohora ibibyimba muri sisitemu yo gukonjesha; Ikibi nuko thermostat ikingura kandi igafunga mugihe ikora, ikabyara ihungabana.
Iyo moteri ikora ya moteri iri hasi (munsi ya 70 ° C), thermostat ihita ifunga inzira igana imirasire, ikingura inzira igana pompe yamazi. Amazi akonje asohoka mu ikoti ry'amazi yinjira muri pompe y'amazi anyuze muri hose, hanyuma yoherezwa mu ikoti ry'amazi na pompe y'amazi kugirango azenguruke. Kuberako amazi akonje adatandukana na radiator, ubushyuhe bwakazi bwa moteri burashobora kwiyongera vuba. Iyo ubushyuhe bwakazi bwa moteri buri hejuru (hejuru ya 80 ° C), thermostat ihita ifunga inzira igana pompe yamazi, igakingura inzira igana kumirasire. Amazi akonje asohoka mu ikoti ry'amazi akonjeshwa na radiatori hanyuma akoherezwa mu ikoti ry'amazi na pompe y'amazi, ibyo bigatuma ubukonje bukonja kandi bikabuza moteri gushyuha. Iyi nzira yinzira yitwa cycle nini. Iyo moteri ikora ubushyuhe buri hagati ya 70 ° C na 80 ° C, inzinguzingo nini nini ntoya ibaho icyarimwe, ni ukuvuga igice cyamazi akonje kumuzingo munini, naho ikindi gice cyamazi akonje kugirango azenguruke.
Imikorere yimodoka thermostat nugufunga imodoka mbere yuko ubushyuhe butagera kubushyuhe busanzwe. Muri iki gihe, amazi akonje ya moteri asubizwa kuri moteri na pompe yamazi, kandi kuzenguruka gato muri moteri birakorwa kugirango moteri ishyushye vuba. Iyo ubushyuhe burenze ibisanzwe burashobora gufungurwa, kugirango amazi akonje anyuze mumatara yose ya radiator kugirango azenguruke cyane, kugirango ubushyuhe bwihuse.
