Patent number: 10435064Abstract: A steering system for a vehicle includes a fluid pump, an actuator in selective fluid communication with the fluid pump, a hydrostatic steering system and an electro-hydraulic steering system. The hydrostatic steering system includes a fluid controller having a first proportional valve in fluid communication with the fluid pump and a fluid meter in fluid communication with the first proportional valve and the actuator. The electro-hydraulic steering system includes a second proportional valve in selective fluid communication with the fluid pump and the actuator. The second proportional valve is disposed in parallel to the first proportional valve. The electro-hydraulic steering circuit further includes a load-reaction switching valve assembly disposed in series with the first proportional valve of the hydrostatic steering system.

Patent number: 9920776Abstract: A fluid controller includes a valve housing having an inlet port, a return port, first and second control ports and a load sense port. The fluid controller further includes a fluid meter in selective fluid communication with the valve housing and a valve assembly adapted to provide selective fluid communication between the valve housing and the fluid meter.

Patent number: 9200645Abstract: An aspect of the present disclosure relates to a steering system having first and second steering circuits in fluid communication with a fluid actuator wherein the steering circuits are disposed in parallel to each other. The second steering circuit includes a proportional valve having a load-sense feature in selective fluid communication with a load-sense connection and the first steering circuit. The load-sense feature is open to the first steering circuit when the proportional valve is in a neutral position and closed to the first steering circuit when the proportional valve is moved to a first or second steering position. When the proportional valve is actuated from the neutral position to the first or second steering position the movement of the proportional valve closes the load sense feature from the first steering circuit and operates to deactivate the first steering circuit.Type: GrantFiled: September 28, 2012Date of Patent: December 1, 2015Assignee: Eaton CorporationInventor: Aaron Kelly Krahn

Patent number: 8397858Abstract: A steering system includes a steer-by-wire (SBW) valve, a main steering pump, a steering actuator, and a steering control unit (SCU). The SCU is in fluid communication with the actuator via a pair of fluid conduits, and includes upper and lower portions. The upper portion contains a first solenoid valve and a cross-over check valve assembly. The lower portion contains a fluid control valve. An ECU generates a steering input signal in response to steering wheel rotation, and transmits the signal to the SBW valve. The SCU controls the first solenoid valve to deliver fluid from the lower portion to the actuator via the cross-over valve assembly in an emergency steering mode, and also controls the first solenoid valve to prevent flow into the actuator and allow recirculation of fluid within the lower portion in a torque feel mode.Type: GrantFiled: May 19, 2011Date of Patent: March 19, 2013Assignee: Eaton CorporationInventor: Aaron Kelly Krahn

Publication number: 20120279065Abstract: The present disclosure relates to a method for removing barrel nuts used for securing a plurality of studs to a turbine blade. Each stud is individually coupled to a respective barrel nut such that each barrel nut is anchored to a root end of the turbine blade. The barrel nut is heated to a predetermined temperature using a controller and a thermocouple. An adhesion between the barrel nut and the turbine blade is overcome and the barrel nut is extracted from the turbine blade. The barrel nut is removed from the turbine blade by connecting an extractor assembly or barrel nut removal device. This is accomplished from an interior surface of a root end of the turbine blade such that this method allows one to remove and replace barrel nuts while the turbine blade remains attached to the hub.Type: ApplicationFiled: May 6, 2011Publication date: November 8, 2012Inventors: Mark Paul Elliott, Aaron Kelly Wahlstrom

The selector valve is adapted for rotational movement between a first position and a second position and includes a first face and an oppositely disposed second face. The selector valve defines a plurality of thru-passages that extend axially through the first and second faces and that is adapted to provide fluid communication between the first and second volume chambers in the first position. The selector valve defines a groove disposed on the second face. The groove recirculates fluid from the second plurality of volume chambers when the selector valve is in the second position.Type: GrantFiled: February 2, 2009Date of Patent: July 24, 2012Assignee: Eaton CorporationInventors: William John Novacek, Aaron Kelly Krahn
