Gasi chitubu buffer kabati gasi chitubu chinhu elastic chine gasi uye mvura sechishandiso chekushanda. Iyo inoumbwa nekumanikidza pombi, piston, piston tsvimbo uye akati wandei ekubatanidza zvidimbu. Mukati mayo muzere ne-high-pressure nitrogen. Nekuda kwekuti pane gomba mupiston, magasi kumagumo ese episton akaenzana, asi nzvimbo dzechikamu kumativi ese episton dzakasiyana. Imwe magumo yakabatana nepiston tsvimbo uye imwe magumo haina. Pasi pesimba rekumanikidzwa kwegasi, kudzvanywa kwakananga kudivi rine diki chikamu nzvimbo inogadzirwa, ndiko kuti, iyo elastic simba yechitubu chegasi. Saizi yesimba re elastic inogona kuiswa nekuisa akasiyana nitrogen kumanikidza kana piston tsvimbo ine madhayamita akasiyana. Mhepo chitubu chebuffer kabati inoshandiswa zvakanyanya mukusimudza chikamu, tsigiro, giravhiti chiyero uye kutsiva yakanakisa mechaniki chitubu. Iyo yemhepo chitubu chebuffer kabati inogadzirwa neyazvino chimiro chemafuta edunhu kutenderera kudzora kutamiswa kwegasi, iine hunhu hwakanakisa hwekukwira buffer uye chiedza panzvimbo.
