The plunger is telescopic, i.e., extendable and retractable. The plunger includes two ferromagnetic portions that are movable relative to one another and relative to the passage. The portions are fitted one inside the other and define air gaps E2 and E3 therebetween. The valve includes a magnet and a spring on either side of a secondary portion to hold the secondary portion in the closed position, distancing a ball from the exhaust seat.

  • Patent number: 9611950
    Abstract: A valve calibration system and method is disclosed for an electrohydraulic valve having upstream and downstream sides. A valve current controls the valve orifice size connecting the upstream and downstream sides. The calibration method includes opening the valve, stalling the system to prevent volume changes, and closing the valve with substantially equalized upstream and downstream pressures; then increasing upstream pressure, and finding a calibration current that provides a calibration orifice size through the valve by monitoring downstream pressure. Finding a calibration current can include stepping through valve control currents, sensing downstream pressures, and calculating step orifice sizes until the calculated step orifice size is greater than or equal to the calibration orifice size. Finding a calibration current can include performing a coarse calibration followed by a finer calibration. An offset can be calculated for a valve characteristic relating valve control current to valve orifice size.

  • Patent number: 9360023
    Abstract: A hydraulic system has a cylinder and ram assembly that raises and lowers a load carrying carriage on a material handling vehicle. The fluid exhausting from the cylinder, while the carriage is lowering, is controlled to recover energy from that fluid. A first path routes the exhausting fluid to drive the pump as a hydraulic motor. A second path routes the exhausting fluid to a reservoir, bypassing the pump. In a first lowering mode, the second path is closed and the first path is opened. In a second lowering mode, both the first and second paths are open and the flow through each one is proportionally controlled. In a third lowering mode, only the second path is opened. The mode to use is selected based on the desired lowering speed of the carriage.

  • Patent number: 9346489
    Abstract: A steering system with magnetic torque overlay of a vehicle is provided. The system comprises a hydraulic valve and differential-pressure transducer that monitors pressure created by the valve due to torque exerted by a driver of the vehicle in various directions on a steering wheel thereof. The transducer is fastened to a recirculating ball steering gear. A magnetic actuator generates an output of torque required from the steering gear for a maneuver of the steering wheel and applies the torque to the valve independently of input by the driver. A permanent magnet is located proximate the actuator. A control module calculates an appropriate amount of electric current and sends it to the actuator to generate the output torque. The torque is added to or subtracted from the system in any of the directions independently of the driver input by the pressure-monitoring and inputs from the vehicle into the control module.
