REFLECTOR: Nose gear Hydraulic Regulator

[Ronnie Brown]

Re: REFLECTOR: Nose gear Hydraulic RegulatorAnother way to fix this "slamming shut" problem is to locate the nose door sequence control valve so that it is actuated by one of the reinforcing webs on the nose gear strut.  See chapter 7 of the new on line manuals.  Mine is installed this way and the doors close smoothly and with no slamming. This might be difficult to change on an plane already completed, but for others with the old manuals, I highly recommend this change.  This new location for the sequence valve is also much easier to get to make the adjustments.

This location works because the valve is opened slowly by the relatively slow movement of the gear near the gear pivot point.

  Steve,

    I used a flow control valve on my nose gear door cylinder as you mentioned.  It came from a local hydraulic supply shop and cost $38.00 in 1995.  When my canard is off for the annual this month, I can look at the make and model of the valve.  It seems like the body of the valve was about 1" x 1" x 2.5" with a knurled knob on top.  The knob adjusts the flow (pretty sensitive) and a set screw locks the knob in position.  Sometimes the gear up pressure switch will cause the pump to cycle once as the nose doors slowly close.

    I am wondering if anybody has a part number and a location for an inline regulator for the nose gear hydraulic cylinder.  My nose gear doors slam close and Scott Swing said some people are using an in line regulator to slow them down.  Any help would be appreciated.
    Thanks Steve
