Latest Patents

One of his latest patents is the "Electrohydraulic Servovalve." This invention features a two-stage miniature electrohydraulic servovalve that includes an electromagnetic positioner. The positioner has a flexure tube mounted drive arm that is secured to and movable with an armature. This armature moves in accordance with a combined magnetic field resulting from both permanent magnets and an electrical signal fed to electromagnetic coils. The design includes a four-way hydraulic valve main stage with a valve body that has a sleeve mounted therein, featuring two annular, internal, axially spaced apart metering grooves. A metering spool with five lands alternating with four metering grooves is positioned within the sleeve for controlled axial movement. Additionally, the invention includes end caps positioned over the ends of the sleeve and a jet pipe pilot stage that features a jet pipe member secured to the end of the drive arm. This member has a jet pipe nozzle aligned with the drive arm and a hydraulic fluid feeder passage disposed at right angles to the plane of movement of the drive arm. A resiliently mounted counterbalance is also positioned on the drive arm, along with passages in the spool from adjacent the jet pipe nozzle to the opposite ends of the spool.

Another significant patent is the "Laminated Jet Pipe Receiver Plug Assembly Method and Structure." This invention involves a laminated plate cylindrical receiver plug assembly structure that has rectangular cross-section passages extending axially through one end of the plug assembly. The assembly is produced by creating a plurality of separate plates with axially and/or transversely extending openings in rectangular form. Every other plate is coated with brazing material, and the plates are placed in side-by-side surface engagement to form the necessary passages. They are then subjected to brazing temperature and pressure before being machined into a cylindrical form.
