Low frequency absorption device for injector, has body connected to injector`s rod and having ballast, where body displacement is damped radially and longitudinally by presence of viscous fluid around ballast and under plate, respectively
The device has a body (8) movably mounted in a cavity (6) of an injector (1) and connected to a rod (4) of the injector. The body has a cylindrical pre-stressing ballast (10), where the displacement of the body is damped radially by the presence of a viscous fluid e.g. oil, around the ballast and longitudinally by the presence of the fluid under a plate. An upper end of the ballast extends radially by the plate.
