kugenzura inshuro ebyiri birashoboka gucunga inkunga nigikorwa cyumutwaro wahagaritswe mubyerekezo byombi byerekana. Ubusanzwe ikoreshwa kuri ubu bwoko bwa valve iri imbere ya silindiri ikora kabiri ushaka gufunga mumurimo cyangwa kuruhuka. Ikirangantego cya hydraulic cyemezwa na poppet ikomye kandi yubutaka. Nkesha igipimo cyindege, igitutu cyo kurekura kiri munsi yicyatewe numutwaro wahagaritswe.

Imiyoboro ya VRDF iraboneka hamwe na BSPP-GAS ibyambu byanditseho kubitangwa no kugaruka kumurongo hamwe nibyambu byahinduwe kumurongo ugana kuri silinderi. Ukurikije ubunini bwatoranijwe, barashobora gukorana nigitutu cyo gukora kigera kuri 350 bar (5075 PSI) na 45 lpm (13.2 gpm) umuvuduko. Umubiri wo hanze wakozwe mubyuma bikomeye kandi birinda hanze okiside hamwe no kuvura galvanizing. Ubuvuzi bwa Zinc / Nickel burahari kubisabwa kubisabwa cyane cyane byangiza ibintu.
