stdClass Object ( [id] => 1380331 [title] => Sve vas zanima kako se zaustavlja pištolj za točenje gorivo na bezninskoj pumpi. Evo kako [alias] => sve-vas-zanima-kako-se-zaustavlja-pistolj-za-tocenje-gorivo-na-bezninskoj-pumpi-evo-kako [catid] => 299 [published] => 1 [introtext] => [fulltext] =>

Svaki vozač automobila često odlazi na benzinske pumpe i u svog ljubimca sipa gorivo bez kojeg ne može voziti. No kako funkcionira mehanizam u pištolju sigurno su barem jednom pitali. Princip je vrlo jednostavan: Svinuta metalna cijev ‘pištolja’ za ulijevanje goriva u automobil ima cjevčicu povezanu s podtlačnom komorom i membranom. Da bi pumpa goriva radila, u cjevčici mora biti podtlak. Dok gorivo slobodno ističe iz glavne cijevi, povlači zrak, odnosno gorivne pare, iz cjevčice stvarajući podtlak u komori spojenom na cjevčicu.

---

---

Stvoreni podtlak povlači membranu, na čijoj je sredini strujni kontakt spaja napajanje elektromotora pumpe. Kad se razina goriva približi čepu, počinje rasti tlak zraka odnosno gorivnih para na otvoru, koji poništava podtlak u cjevčici, odnosno komori na koju je spojena. Elastična membrana se tada vraća u početni položaj, razdvaja strujne kontakte i prekida dovod struje u elektromotor stacionarnog uređaja za točenje goriva iz velikog podzemnog ‘tanka’ u spremnik automobila.

Svaki vozač automobila često odlazi na benzinske pumpe i u svog ljubimca sipa gorivo bez kojeg ne može voziti. No kako funkcionira mehanizam u pištolju sigurno su barem jednom pitali. Princip je vrlo jednostavan: Svinuta metalna cijev ‘pištolja’ za ulijevanje goriva u automobil ima cjevčicu povezanu s podtlačnom komorom i membranom. Da bi pumpa goriva radila, u cjevčici mora biti podtlak. Dok gorivo slobodno ističe iz glavne cijevi, povlači zrak, odnosno gorivne pare, iz cjevčice stvarajući podtlak u komori spojenom na cjevčicu.

---

Stvoreni podtlak povlači membranu, na čijoj je sredini strujni kontakt spaja napajanje elektromotora pumpe. Kad se razina goriva približi čepu, počinje rasti tlak zraka odnosno gorivnih para na otvoru, koji poništava podtlak u cjevčici, odnosno komori na koju je spojena. Elastična membrana se tada vraća u početni položaj, razdvaja strujne kontakte i prekida dovod struje u elektromotor stacionarnog uređaja za točenje goriva iz velikog podzemnog ‘tanka’ u spremnik automobila.
