Auto lubrication directional valve DR4-5 Kushanda:
Iyo pressure regulator chitubu inomanikidzwa nebhuroko papiston 1 kugadzira piston 1 kuruboshwe rweimba yevharuvhu mukamuri chiteshi che auto lubrication directional valve DR4 (Yakaratidzwa Mufananidzo-1), piston 1 uye piston 2 zviri. zvakateerana zvakabatana kuburikidza nemafuta ekubuda 1 uye mafuta ekubuda 2.

Oiri yekumanikidza inopinda mumakomba maviri episton 3 (Mufananidzo-2) kubva pachiteshi chemafuta, umo mafuta ekumanikidza ari mukamuri yekuruboshwe anoyerera achibuda nepachiteshi chemafuta 1 uye mafuta ekumanikidza anoita kuruboshwe kuruboshwe. iyo piston 3 kuburikidza nepiston 1 yemukati mhango mudivi rerudyi reimba yevharuvhu, ipapo piston 3 inoramba iri kurudyi rweimba yevharuvhu, nepo kurudyi rwepiston 3 inosangana nemafuta ekudzosera port. Rutivi rwerudyi rwegomba rekumanikidza mafuta rakanamwa nepiston 2, kana kuruboshwe kwepiston 1 (outlet pressure) kukunda simba rechitubu papiston, piston 1 kuruboshwe, nepo piston 2. kuruboshwe zvakare.

Kana piston 1 nepiston 2 zvichienda kumucheto wekurudyi weimba yevharuvhu (Mufananidzo Wakaratidzwa-3), rutivi rworuboshwe rwepiston 3 rwakabatana nechiteshi chekudzorera oiri, uye mafuta ekumanikidza anoita kurudyi rwepiston. 3 kuburikidza nemukati memukati wepiston 2, kusundira piston kuruboshwe rweimba yevharuvhu. Panguva ino, mafuta ekumanikidza ari mugomba rekurudyi repiston 3 anoyerera achibuda nepakati pemafuta ekubuda 2, uye mafuta ekumanikidza kumucheto wekuruboshwe anovharwa nepiston 1. Kana kudzvanywa (kubuda kwekumanikidza) kwemugumo wekurudyi we iyo piston 2 inokunda chiito chechitubu ichipokana nepiston, piston 2 inochinjirwa kurudyi uye piston 1 inochinjirwa kurudyi. Kana piston 1 uye piston 2 zvichienda kuruboshwe kumagumo eimba yevharuvhu, rutivi rworudyi rwepiston 3 rwakabatana nechiteshi chekudzorera mafuta, uye mafuta ekumanikidza anoita kuruboshwe rwepiston 3 kuburikidza nemukati wekati. iyo piston 1, ichisaidzira pisitoni kurudyi kurudyi rweimba yevharuvhu (Mufananidzo Wakaratidzwa-1), kupedzisa kutenderera kwebasa.

Ongorora: Kana ukaona mamiriro ekuchinja kweiyo lubrication directional valve, unogona kuisa switching sign sender pavharuvhu, kana mafuta ekudzvanya achifambisa kubva ku "oiri port 1" kuenda ku "oiri port 2", iyo valve piston kufamba, macontacts ari mune anotumira masaini anovharwa, uye kana piston yafambiswa ichidzokera kumashure, mabatiro anobviswa uye transmitter inogona kubatanidzwa kune controller kana yekutarisa mudziyo sezvinodiwa.
Mukuwedzera, mutyairi ane chubhu inoonekera pane transmitter inogona kutariswa zvakananga kune kufamba kwechiratidzo tsvimbo.
