  • Butterfly valves having sleeve inserts
    Patent number: 8091862
    Abstract: A butterfly valve having a valve body, a butterfly shaft, a butterfly plate, and a sleeve insert is provided. The valve body is made of a first material and the sleeve insert is made of a second material. The butterfly shaft is in the valve body for rotation about a first axis. The butterfly plate is in the valve body and secured to the butterfly shaft so that rotation of the butterfly shaft causes the butterfly plate to rotate about a second axis through a travel path between a closed position and an open position. The sleeve insert is in the valve body at least in a region of the travel path between the valve body and the butterfly plate.

  • Fuel transfer system for aircraft
    Patent number: 4932609
    Abstract: Parallel transfer pumps (92, 94) operate to transfer fuel from auxiliary tanks (52, 60, 66) to the main tank (10). A pressure sensor (106) in the pump discharge line in combination with tank level rate mechanisms (86, 88, 90) sequences pumps (92, 92) and transfer valves (100, 102) if required, and confirms successful transfer or alarms when unsuccessful.
