Thermostat rudzi rwemudziyo unodzora tembiricha otomatiki, unowanzova nechikamu chekuona tembiricha, nekuwedzera kana kudzikira kuti ubate uye udzime kuyerera kwemvura inotonhodza, kureva kuti, unogadzirisa mvura muradiator otomatiki zvichienderana netembiricha yemvura inotonhodza, uchichinja huwandu hwekutenderera kwemvura inotonhodza, kuti ugadzirise kugona kwekupisa kwesystem yekutonhodza.
Iyo huru thermostat yeinjini i thermostat yemhando ye wax, iyo inodzorwa neparafini mukati kuburikidza nepfungwa yekuwedzera kupisa uye kudzika kwechando kudzora kutenderera kwe coolant. Kana tembiricha yekutonhodza yakaderera pane kukosha kwakataurwa, parafini yakanatswa mumuviri we thermostat inonzwa tembiricha yakasimba, vharuvhu ye thermostat iri pasi pekushanda kwechitubu kuvhara nzira iri pakati peinjini ne radiator, coolant inopfuura nepombi yemvura kuti idzokere kuinjini, injini inotenderera zvishoma. Kana tembiricha ye coolant yasvika kukosha kwakataurwa, parafini inotanga kunyunguduka uye zvishoma nezvishoma inova mvura, uye huwandu hunowedzera uye hunodzvanya chubhu yerabha kuti iite kuti iderere. Panguva imwe chete, chubhu yerabha inoderera uye inoisa push rod kumusoro. Push rod ine push yekudzika pasi pavharuvhu kuti ivhure vharuvhu. Panguva ino, coolant inoyerera nepakati pe radiator ne thermostat valve, uye yobva yadzokera kuinjini kuburikidza nepombi yemvura kuti ideredze kutenderera kukuru. Yakawanda ye thermostat yakarongwa mupombi yekubuditsa mvura yemusoro we cylinder, ine mukana wekuva nyore uye nyore kuburitsa mabubbles mu system yekutonhodza; Dambudziko nderekuti thermostat inowanzo vhura nekuvharika kana ichishanda, zvichiita kuti pave nekutenderera kwemhepo.
Kana tembiricha yekushanda kweinjini yadzikira (pasi pe70°C), thermostat inovhara yega nzira inoenda kuradiyeta, uye inovhura nzira inoenda kupombi yemvura. Mvura inotonhodza inobuda mujaketi remvura inopinda mupombi yemvura zvakananga kuburikidza nepaipi, uye inotumirwa kujaketi remvura nepombi yemvura kuti ifambe. Nekuti mvura inotonhodza haiperi neradiyeta, tembiricha yekushanda yeinjini inogona kuwedzerwa nekukurumidza. Kana tembiricha yekushanda yeinjini yakakwira (pamusoro pe80°C), thermostat inovhara yega nzira inoenda kupombi yemvura, uye inovhura nzira inoenda kuradiyeta. Mvura inotonhodza inobuda mujaketi remvura inotonhodzwa neradiyeta uye yozotumirwa kujaketi remvura nepombi yemvura, izvo zvinovandudza kutonhora uye zvinodzivirira injini kubva pakupisa. Nzira iyi yekutenderera inonzi kutenderera kukuru. Kana tembiricha yekushanda kweinjini iri pakati pe70°C ne80°C, kutenderera kukuru nediki kunowanikwa panguva imwe chete, kureva, chikamu chemvura inotonhodza yekufamba kukuru, uye chimwe chikamu chemvura inotonhodza yekufamba kudiki.
Basa remota thermostat nderekuvhara mota tembiricha isati yasvika patembiricha yakajairika. Panguva ino, mvura inotonhodza yeinjini inodzoserwa kuinjini nepombi yemvura, uye kutenderera kudiki kweinjini kunoitwa kuti injini idziye nekukurumidza. Kana tembiricha yadarika yakajairika inogona kuvhurwa, kuitira kuti mvura inotonhodza ichipinda netangi rese reradiator kuti ifambise zvakanyanya, kuitira kuti ikwanise kupisa nekukurumidza.
