Latest Patents

Ferguson's latest patents include a tool and method for coining corner breaks in a stator of a power steering system. This invention involves a method and apparatus for coining a valve sleeve member for a power steering valve. The design features arm portions of the coining apparatus that spread radially outward into associated oil grooves in the valve sleeve. A hardened coining land deforms corner breaks defined between the oil groove and the inner land region of the valve sleeve. The arm portions are then moved radially inward, allowing for the removal of the coining apparatus from the valve sleeve. Additionally, the coining apparatus includes a tapered recess that extends along a substantial axial dimension, enhancing its functionality.

Another significant patent by Ferguson is an assembly and method for coining a precision corner break on an oil metering flat for a rotor of a power steering rotary valve. This method begins with placing a workpiece in a first floating position set by a clamping and orientating device. The workpiece is then engaged with a plurality of circumferentially spaced coining dies, allowing it to float to a second coining position. The final step involves coining the workpiece to a precision depth, which is selectively adjustable through a motion conversion means. This innovative approach showcases Ferguson's expertise in creating precise engineering solutions.
