Ma viscous fluid dampers ndi zida zama hydraulic zomwe zimawononga mphamvu ya kinetic ya zochitika za zivomezi ndikuthandizira kukhudzidwa pakati pa zomanga.Zimakhala zosunthika ndipo zimatha kupangidwa kuti zilole kuyenda kwaufulu komanso kuwongolera kwadongosolo kuti zitetezeke ku mphepo yamkuntho, kuyenda kwamafuta kapena zochitika za zivomezi.
Damper ya viscous fluid imakhala ndi silinda yamafuta, pisitoni, ndodo ya pistoni, lining, sing'anga, mutu wa pini ndi mbali zina zazikulu.Pistoni imatha kusuntha mobwerezabwereza mu silinda yamafuta.Pistoniyo ili ndi mawonekedwe onyowa ndipo silinda yamafuta imakhala yodzaza ndi sing'anga yonyowetsa madzi.
