Possibilities of effective passive vibration isolation of hydraulic valves

The following paper describes the effect of the introduced vibration isolation on the operation of a hydraulic valve. The method of transmitting the external force to the valve control element and examples of vibration sources are presented. The balance of forces acting on the valve spool and the flow intensity in the tested hydraulic system are determined. The assumptions are simplified and discussed in detail. On their basis, numerical simulations have been carried out and verified by experimental tests. The paper ends with brief conclusions.
