  • Control system for spool valve avoiding mechanical stresses
    Patent number: 10823307
    Abstract: A fluid pressure controlled spool valve minimizes abrasion or sticking caused by a tilted orientation of a pressure plate forcing lands of a spool shaft to abrade or stick internally facing surfaces of a cylindrical barrel supporting the spool shaft. A permanent magnet is mounted on the pressure plate. A round head composed of a ferromagnetic material is formed on an end of a spool shaft and configured to be magnetically attracted to the permanent magnet. A magnetic attraction force vector produced on the round head of the spool shaft remains coaxial with an axis of the spool shaft, when the pressure plate and the magnet are tilted with respect to the axis of the spool shaft.
