Urukurikirane rwa BPV ni rusanzwe rukoreshwa rwihuta rukwiranye no guhuza inkokora ya dogere 90 ya L na shitingi yo mu kirere. Ubu bwoko bwimikorere ihindagurika bikozwe mubikoresho bya pulasitike kandi bifite ibimenyetso biranga uburemere bworoshye, birwanya ruswa, kandi birwanya kwambara, bigatuma bikwiranye na sisitemu yumubiri.
Ubu bwoko bwihuza bufite imikorere yo gukanda byihuse, bishobora guhuza byihuse kandi byoroshye guhuza no guhagarika ama hose. Uburyo bwayo bwo guhuza buroroshye, gusa shyiramo hose muri connexion hanyuma uyizenguruke kugirango uyizirike kugirango urangize ihuriro. Mugihe uhagaritse, kanda buto kugirango uhite utandukanya hose.
L-90 ya dogere ya plastike yumuyaga wa pisine ihuriweho nubumwe inkokora pneumatike ikoreshwa cyane munganda, ubuhinzi, ningo. Irakoreshwa muguhuza ibikoresho bya pneumatike, compressor, imashini zumusonga nibindi bikoresho bya pneumatike. Igishushanyo cyacyo gituma umwuka ugenda neza kandi utanga ihererekanyabubasha ryumuyaga.
