Mumakore ekuma1930,vharuvhu yeshavishaviYakatangwa muUnited States, uye muma1950, yakaunzwa kuJapan. Kunyange zvazvo isina kushandiswa zvakanyanya muJapan kusvika kuma1960, haina kuzivikanwa zvakanyanya pano kusvika kuma1970.

Hunhu hukuru hwevharuvhu remapuruguru huremu hwaro hwakareruka, nzvimbo yaro yekumisikidza iri nyore, uye simba rayo rekushanda rakaderera. Vharuvhu remapuruguru rinorema anenge 2T, nepo vharuvhu regedhi rinorema anenge 3.5T, uchishandisa DN1000 semuenzaniso. Vharuvhu remapuruguru rine mwero wakasimba wekugara kwenguva refu uye kuvimbika uye riri nyore kubatanidza nemaitiro akasiyana ekutyaira. Dambudziko revharuvhu remapuruguru rakavharirwa nerabha nderekuti, kana rikashandiswa zvisina kunaka sevharuvhu rinopwanya, kuvhurika kwegumbo kunoitika, zvichiita kuti chigaro cherabha chibviswe uye chikanganiswe. Saka, sarudzo chaiyo inoenderana nemamiriro ekushanda. Mwero wekuyerera unochinja-chinja zvichienderana nekuvhurwa kwevharuvhu remapuruguru.

Kana ikashandiswa kudzora kuyerera kwemvura, hunhu hwayo hwekuyerera hunoenderana zvakanyanya nekusagona kuyerera kwepaipi. Semuenzaniso, kuyerera kwemvura kwemavharuvhu kunosiyana zvakanyanya kana mapaipi maviri akaiswa dhayamita nechimiro chakafanana chevharuvhu, asi ma coefficients akasiyana ekurasikirwa kwemvura nemapaipi. Kuvhurika kwemvura kunogona kuitika kumashure kwevharuvhu apo vharuvhu iri munzvimbo inorema yekukweva, izvo zvinogona kukuvadza vharuvhu. inowanzoiswa kunze pa15°.

Iyovharuvhu yeshavishaviInoumba chimiro chakasiyana kana iri pakati pekuvhurwa kwayo, apo kumberi kwepuratifomu yeshavi reshavi nemuviri wevharuvhu zviri pakati peshavi revharuvhu. Kumberi kwepuratifomu imwe yeshavi reshavi kunofamba nenzira imwe chete.

Nekuda kweizvozvo, rimwe divi remuviri wevharuvhu uyevharuvhuplate inobatana kuti iite aperture yakaita se nozzle, nepo rimwe divi rakaita se throttle. Gasket yerabha yakabviswa. Torque yekushanda kwevharuvhu remashavi inosiyana zvichienderana nekuvhura nekuvhara kwevharuvhu. Nekuda kwehudzamu hwemvura, torque inogadzirwa nekusiyana pakati pemisoro yemvura yepamusoro neyepasi yevharuvhu haigone kufuratirwa kune mavharuvhu emashavi emashavi akatambanuka, kunyanya mavharuvhu ane dhayamita hombe.

Pamusoro pezvo, kuyerera kwebias kuchaumbwa uye torque ichakwira kana gokora raiswa parutivi rwekupinda kwevharuvhu. Nekuda kwemhedzisiro yetorque yekuyerera kwemvura kana vharuvhu iri pakati pekuvhurika, mashandiro ekushanda anofanira kunge achizvivharira ega.
