  • Steering system with dynamic slip reduction
    Patent number: 9238479
    Abstract: A steering system includes a fluid motor and a steering unit. The steering unit is in fluid communication with the fluid motor. The steering unit includes a fluid meter adapted to meter fluid to the fluid motor in response to actuation of the steering unit. A valve housing is in fluid communication with the fluid meter. The valve housing defines a valve bore. A valve assembly is disposed in the valve bore. The valve assembly defines a primary fluid path to the fluid meter and to the fluid motor from the fluid meter. The valve assembly further defines a secondary fluid path to the fluid motor that bypasses the fluid meter. An amount of fluid through the secondary fluid path is based on volumetric efficiency of the fluid motor.
