I-orifice valve plate iyidiski yensimbi enembobo eqondile, okuthi uma ifakwe epayipini ivimbele ukugeleza koketshezi futhi inciphise ukucindezela. Amapuleti ama-valve e-Orifice abalulekile ezimbonini eziphatha imikhiqizo ewuketshezi negesi njengoba akha isisekelo sesilinganiso sokugeleza koketshezi kumamitha okugeleza kwe-orifice.

I-orifice valve plate ichazwa ukuthi isetshenziswe kumjovo kaphethiloli kagesi wohlobo olusetshenziselwa ukukhipha uphethiloli emagumbini avuthayo enjini evuthayo yangaphakathi. I-orifice valve plate ingeyokucushwa okuyindilinga enendawo engaphezulu komfula kanye nendawo engaphansi ephikiswayo kanye ne-eksisi emaphakathi. I-axis ye-orifice passage ihlehliselwe phansi nge-engeli eya e-eksisi emaphakathi futhi inwebeke ngaphakathi ukusuka enhla nomfudlana iye emaphethelweni angezansi omzila we-orifice ukuze umzila ngamunye we-orifice uqondise umfudlana wamafutha ezansi nomfula ngase-eksisi emaphakathi lapho imifudlana kusuka eziphasejini ze-orifice ngakho-ke okungenani kuzoshayisana ngokwengxenye ukuze kukhiqizwe isamba sephethini yesifutho sikaphethiloli ehlanganisiwe.

Inzuzo yayo ukuthi ingxenye ye-throttle ayidingi ukulinganiswa, futhi ukulinganisa kunembile. Isakhiwo esilula, esihlangene, usayizi omncane, isisindo esilula. Uhlu olubanzi lwezinhlelo zokusebenza, okuhlanganisa zonke uketshezi lwesigaba esisodwa kanye nokugeleza kwe-multiphase. Amapuleti ama-valve e-Orifice ezikhala ezihlukene angashintshwa ngokuqhubekayo ngokushintsha kwezinga lokugeleza, futhi angahlolwa futhi ashintshwe ku-inthanethi.
