Abstract
A typical oil hydraulic over center valve system and a time domain
simulation model is introduced together with a hypothesis that
flow force compensation should reduce the inherent oscillatory
behavior of such hydraulic systems. A few results are shown from a
parameter study that confirms this assumption and an approach
to design over center valve geometries that have negative flow
forces is presented with emphasis on predictability. In
conclusion it is made clear that negative flow forces in the over
center valve cannot solve the instability problem in general,
however, it might very well be a method like lowering the pilot
ratio, that can be used to application specific instability
problems.
