摘要：
The article presents test results of static friction forces acting on a spool of a hydraulic directional control valve loaded with axial forces and forces related to the liquid flow. The presented results indicate that it seems reasonable to include frictional forces dependent on the size of axial forces acting on a spool in the mathematical models describing spool movement in directional control valves. This type of dependence does not exist in the commonly used models describing the operational dynamics of the spool-sleeve pair, which may affect the achieved levels of compliance with test results.
