Valve yakulongozgera maji

WHQ na WQQ mavavu ni viŵiri - nthowa yimoza - nthowa yimoza - mavavu gha throttle na mapangidwe ghakuŵikika pamwamba.

Valve iyi yikugwiriskira ncito kucepeska msewu ukuru kufuma ku doko limoza panji ghaŵiri gha mafuta agho ghakugwira nchito panji kulaŵilira msewu.

Mavavu ghaŵiri ghakuŵikika mwakuyana gha nthowa yimoza - ghakuchepeska msewu mu nthowa yimoza (mwa kusintha mtundu wa throttle) ndipo ghakuzomerezga msewu waulere mu nthowa yinyake.

Para ŵakugwiliskira ntchito kuti ŵalongozge throttle yakufumiramo, mafuta ghakufuma pa doko la mafuta B kujumpha pa doko la mafuta (1) na kufika pa doko la mafuta B1 ilo likugwira ntchito, ndipo mtundu wa vavu ya throttle (4.1) ungasinthika mwakuyana na axial kwizira mu sikiru yakusinthira (5), mwakuti doko la throttle (1) lingaŵikika.

Pa nyengo yeneyiyo, mafuta agho ghali mu doko la mafuta B ghakujumpha mu mbuna ya mafuta (2) na kufika ku chigaŵa cha spring - chakunyamulika (3) cha mtundu wa vavu (4.1), ndipo nkhongono iyo yikupangika na nkhongono ya spring vikupangiska kuti mtundu wa vavu ya throttle (3.1) uŵe pa malo ghakukhozga.

Para ŵakugwiliskira ntchito vavu ya nthowa yimoza-, mafuta agho ghakunjira kufuma ku doko la mafuta lakugwira ntchito B1 ghakukankhira mtundu wa vavu ya throttle (3.1) ku nkhongono ya spring, ndipo nkhongono iyo yikupangika yikugwira ntchito pamoza na spring kuti mtundu wa vavu ya throttle (3.1) uŵe pa malo ghakujulika. Mafuta ghakuzomerezgeka kuseŵera mwakufwatuka kufuma ku B1 kuya ku B, ndipo vavu yikugwira ntchito nga ni vavu ya nthowa yimoza-pa nyengo iyi.

Malinga na chitsanzo cha vavu, ntchito ya throttling ingaŵa yakunjilirapo panji yakufumiramo.
