Edgeless Valve Spool Design with Variable Clearance

Edgeless Valve Spool Design with Variable Clearance

A valve spool may include a cylindrical spool body having a spool longitudinal axis, a first spool body end wall and a second spool body end wall disposed axially opposite the first spool body end wall, and a spool outer surface. The spool outer surface may include a first spool guide region proxima...

Zusammenfassung:A valve spool may include a cylindrical spool body having a spool longitudinal axis, a first spool body end wall and a second spool body end wall disposed axially opposite the first spool body end wall, and a spool outer surface. The spool outer surface may include a first spool guide region proximate the first spool body end wall and having a spool guide region outer diameter, a second spool guide region proximate the second spool body end wall and having the spool guide region outer diameter, and a spool tight clearance region disposed between the first spool guide region and the second spool guide region. The spool tight clearance region may have a spool tight clearance region outer diameter that is greater than the spool guide region outer diameter.
