  • FLUID QUALITY SENSOR AND COVER ASSEMBLY
    Publication number: 20170328745
    Abstract: A sensor assembly is provided for detecting a concentration of a fluid. The sensor assembly includes a sensing unit and a cover assembly. The sensing unit includes a transmitter configured to transmit a signal into a sensing volume and a receiver configured to receive the signal after the signal passes through a portion of the sensing volume. The cover assembly at least partially encloses the sensing volume and is substantially impermeable to a gas portion of the fluid. The cover assembly includes apertures defined therein which are permeable to the gas portion of the fluid. A first plurality of apertures are defined along a top surface of the cover assembly.
    Type: Application

  • Charge pressure reduction circuit for improved transmission efficiency
    Patent number: 8528684
    Abstract: A charge pressure reduction circuit for a loader backhoe in which a directional control valve causes the charge pump to operate at a system pressure high enough to adequately supply a clutch circuit when conditions indicate the vehicle is operating in a loader or transport mode. The directional control valve causes the charge pump to operate at a lower pressure as, for example, required for a lubrication circuit when conditions indicate the vehicle is in a backhoe operating mode.
