  • Thermal Actuator: Clean & Renewable Energy
    Actuators are simply devices used to transform energy into motion. A thermal actuator is a type of non-electric motor made of components such as a piston and a thermal sensitive material capable of producing linear motion in response to temperature changes. Opposite others devices, a thermal

    concept, a four-seater sports car promising zero emissions. Ford Motor Co. debuted its Model U concept, a takeoff on Henry Ford's Model T, powered by a supercharged hydrogen internal-combustion engine with a hybrid-electric transmission. But clean-technology vehicles were minor announcements compared
  • Gulliver's Engines
    Shrinking full-scale engines to pocket size is no small feat. A running quarter-scale model of a 1937 Harley Knucklehead V-Twin. An electric motor in the base starts the engine. The fuel tank sits where the generator would in the full-sized version. For size reference, adjusting the pushrods takes
  • Accumulators handle the extremes
    . The accumulators feature enormous power reserves, flow rates, and fluid volumes. A standard blowoutpreventer control unit consists of 22 or more 11 or 15-gallon bladder accumulators. They are typically precharged to 1,000 psi, then hydraulically charged to 3,000 psi by electric-motor-driven piston pumps
  • Five pumps power blast-hole drill
    it one of the most productive, according to company engineers. The rig's 1,500-hp diesel engine or 1,400-hp electric motor drive a custom-built gearbox that runs five pumps from Parker Hannifin's Hydraulic Pump Div., Marysville, Ohio. The pumps, in turn, power virtually the entire machine. According
  • Accumulators Deliver New Payoffs
    supplies high-pressure fluid that retracts the cylinder rod, but the weight of the piston rod and attached stringer rods pressurizes fluid on the extend stroke, powering a hydraulic motor that drives a pump. Diverting this high-pressure fluid to charge an accumulator lets it supplement pump flow
