This paper deals with the impact of mechanical vibrations on the environment, particularly on hydraulic valves. The main sources of such vibrations and their effects on hydraulic systems are indicated. Some documents setting down standard requirements for resistance to vibrations and to the noise generated by vibrations are cited. Two ways of reducing the impact of mechanical vibrations on the valve are proposed and a theoretical analysis, constituting the basis for selecting a material for an effective vibration isolator for the valve, is carried out.
