1. Umgaqo osebenzayo we-coupler yevalve yenaliti:

I-coupler yevalve yenaliti itywinwe ngomphezulu wekhowuni yokutywina kunye nefilimu yeoli kwisithuba esingaphezulu. Uxinzelelo kwizibuko le-inlet yoxinzelelo oluphezulu luyafana nolombhobho kaloliwe oqhelekileyo, kwaye uxinzelelo kwizibuko lokuphuma koxinzelelo olusezantsi lusezantsi. I-fuel-low-pressure fuel flows back to the tank fuel from the low-pressure oil passage. Xa i-valve yenaliti ivuliwe, phantsi kwesenzo se-fuel-high-pressure, inxalenye ye-fuel ivuza kwi-port ye-low-pressure outlet port ngokusebenzisa ifilimu yeoli ye-gap. Ngethuba lokuhamba ngokuphindaphindiweyo kwesi sibini, ifilimu yeoli kwi-gap idlala indima yokutywinwa kunye nokuthambisa ngexesha elifanayo, ukwenzela ukuba kuthathelwe ingqalelo ukutywinwa kunye nemiphumo yokugcoba ngexesha elifanayo.

2. Ukuguqulwa kweRadial kwesibini sevalve yenaliti:

Njengoko uxinzelelo lwenkqubo yokubonelela ngamafutha lunyuka, i-groove yokugcina i-oyile kunye ne-sliding surface clearance yendibano yevalve yenaliti ixhomekeke kumthwalo omkhulu. Ibangela i-elastic deformation yokudityaniswa kwevalve yenaliti, itshintshe ubungakanani befilimu ye-radial yokuhanjiswa kwefilimu yeoli kwisithuba esiphakathi kokudityaniswa kwevalve yenaliti, kwaye ngaloo ndlela ichaphazela iimpawu zokutywina zokudityaniswa kwevalve yenaliti. Xa i-gap phakathi kwendibano yevalve yenaliti isanda, ukuhamba kwe-fuel state kwi-gap iyatshintsha, ukuhamba akuzinzile, kwaye i-valve yenaliti ingabonakala i-eccentric okanye i-tilted. Ngakolunye uhlangothi, i-eccentricity yevalve yenaliti yonyusa ukuvuza kwamafutha kwi-gap, enciphisa ukusebenza kokutywinwa kwevalve yenaliti; kwelinye icala, kwicala apho ifilimu yeoli incinci, ivalve yenaliti ixhomekeke kumngcipheko wokukhuhlana okomileyo. Ngoko ke, xa uhlalutya intsimi yokuhamba kwefilimu yeoli kwi-gap, kuyimfuneko ukuqwalasela i-deformation ephezulu yoxinzelelo lwe-valve yokudibanisa. I-radial eyongezelelweyo i-deformation yokudibanisa i-valve yenaliti ihambelana ngokufanelekileyo noxinzelelo lwefilimu yeoli ye-gap.
