Aya mavharuvhu anoshandiswa kudzora mafambiro e actuator uye kuivharira mumativi ese. Kuti kuve nekudzika kwemutoro pasi pekutonga uye kudzivirira huremu hwemutoro kutakurwa vharafu inodzivirira chero cavitation ye actuator.

Aya mavharuvhu akanakira kana akajairwa overcentre mavharuvhu asingashande nemazvo sezvo asina hanya nekumanikidza kumashure.

Ivo zvakare vanobvumira iyo system kudzvanywa kufambisa akawanda actuators munhevedzano. Nyora "A" yakasiyana nekuda kwenzvimbo dzekubatanidza uye chiyero chemutyairi.
