  • Power steering gear with proportional flow divider
    Patent number: 3955473
    Abstract: A flow divider for directing hydraulic fluid to separate hydraulic circuits, including a power steering gear which carries the divider, includes a pair of axially aligned valve spools disposed in a common bore of a valve housing.
