Piston Ring isimbi yesimbi yakaiswa mupiston groove. Kune marudzi maviri episton mhete: compression mhete uye mafuta mhete. Mhete yekumanikidza inogona kushandiswa kuvhara gasi rinopisa rinopisa mukamuri yekupisa. Iyo mhete yemafuta inoshandiswa kukwenya mafuta akawandisa kubva muhumburumbira.
Piston mhete imhando yesimbi elastic mhete ine yakakura yekuwedzera deformation. Iyo yakaunganidzwa mu annular groove inoenderana neprofile. Mhete dzepiston dzinodzorera uye dzinotenderera dzinotsamira pamusiyano wekumanikidza pakati pegasi kana mvura kuti iite chisimbiso pakati pedenderedzwa rekunze remhete necylinder uye rimwe divi remhete negorofu.
Iyo piston mhete ndiyo yakakosha chikamu cheinjini yemafuta. Inovhara gasi rehuni pamwe chete necylinder, piston uye cylinder wall. Injini dzemotokari dzinowanzo shandiswa dzine marudzi maviri edhiziri uye peturu injini, nekuda kwekushanda kwayo kwemafuta kwakasiyana, kushandiswa kwepiston mhete hakuna kufanana, yekutanga piston mhete nekukanda, asi nekufambira mberi kwehunyanzvi, simbi ine simba guru piston mhete yakazvarwa, uye nekuenderera mberi kwekuvandudza kweinjini basa, zvinodiwa zvezvakatipoteredza, zvakasiyana-siyana zvepamberi zvekurapa maapplication, senge plating, plating, plating, electroplating kuiswa kwemuviri, kupeta kwepamusoro, zinc manganese phosphating kurapwa, kuitira kuti basa remhete yepiston ivandudzwe zvakanyanya.
