Kiwikā poepoe hapalua ʻēkenike

Ua like ke ʻano o ka valve hemispherical eccentric me ka valve pōpō ʻano V. He hapalua wale nō ke kumu valve, a he valve pōpō paʻa nō hoʻi ia. Hoʻohana nui ʻia ia no nā ʻāpana paʻa. Hoʻohana nā valve pōpō ʻāpana paʻa a pau i nā valve hemispherical eccentric. Hoʻohana pū kekahi mau hale hana sima i kēia.

ʻO ke kiwikā poepoe ʻano-V a me ke kiwikā semi-pōpō eccentric he mau ʻaoʻao hoʻokahi a hiki ke kahe wale i hoʻokahi ʻaoʻao, ʻaʻole i ke kahe bidirectional, no ka mea ua sila ʻia kona poepoe ma kekahi ʻaoʻao, a ʻaʻole e paʻa ka sila ke kuʻi ʻia e ka ʻaoʻao hope, akā e kahe wale nō i hoʻokahi ʻaoʻao.
