  • Fourier transforms applied to a hydraulic system [abstract] 

    Keim, Timothy; Fales, Roger (University of Missouri--Columbia. Office of Undergraduate Research, 2008)
    Control valves (i.e. poppet valves) are commonly used in hydraulic systems for accurate control of the system response. These valves can only provide accurate responses for a limited frequency range. The bode plot is a ...

  • Metered poppet valve [abstract] 

    Keim, Timothy; Fales, Roger; Cline, C. Harvey O. (Curtis Harvey Omari), 1978-; Li, Chang; Kennedy, Joseph L. (University of Missouri--Columbia. Office of Undergraduate Research, 2007)
    The metering poppet valve is a new design that is trying to maximize stability and performance. Poppet valves are typically not used as metering valves because they have stability issues. This new valve is trying to rectify ...

  • Metered poppet valve [abstract] 

    Keim, Timothy (University of Missouri - Columbia Office of Undergraduate Research, 2006)
    In recent years, the poppet valve has begun to serve more versatile purposes. Before now, the poppet valve was mainly used for emergency release valves while the spool valve was more widely used. The poppet valve has several ...
