Folks,

  I know little about hydraulics … That said I do not understand how the flaps work on the IV-P.

 

One side of the flap cylinder goes to a metering valve and then to the high pressure manifold.

The other side of the flap cylinder goes to the three position flap control …

I assume that in one direction it is manifold pressure, the other direction it is reservoir pressure, and in neutral it is sealed.

 

So I can understand what happens when you have the following:

            1) Flap Switch on reservoir pressure and consequently one side of the flap cylinder, and the other metered from the manifold.

            2) I also understand when the flap is neutral, than no-oil flowing means the flap is locked in the current position.

 

But how do things work when:

3)  The Flap Switch is on manifold pressure and consequently one side of flap cylinder, and the other metered from the manifold ?

 

Inquiring minds want to know,   thanks!
