Lolu hlobo lokuhlunga lungafakwa ngqo ngaphansi kwe-valve eqondisayo kagesi kazibuthe ukuze kuhlungwe ukungcola. It is ikakhulukazi esetshenziswa othomathikhi futhi servo uhlelo.
Inenkomba yokungcola. Lapho into yokuhlunga ivinjwe ukungcoliswa futhi ingcindezi ifinyelela ku-0.5Mpa, inkomba izonikeza amasiginali akhombisa ukuthi into kufanele iguqulwe.
Lolu hlobo lokuhlunga lwenziwa ngengilazi yefayibha. Qhathanisa nezinye izihlungi, isihlungi senzelwe usayizi omncane futhi sinemba ngokunemba kokuhlunga, ingcindezi yokuqala ephansi, namandla aphezulu okubamba ukungcola. Isihlungi isilinganiso3.3,5,10,20> 200, ukusebenza ngokuhlunga n> 99.5%, bese ulingana ne-ISO ejwayelekile.
