Abstract
The analysis of one of the common four way underlap hydraulic spool valve construction is presented. The flow force in the valve is deduced and used in building a steady state model for the valve based on the continuity and momentum equations.
The flow damping coefficient is illustrated for differnt damping length ratios. The steady state flow force is discussed for different flow parameters. The effect of the spool valve parameters, the flow stiffness and the positioner spring rate on the valve performance are illustrated.
