ABSTRACT:
A port control member (80) is depressed by either a mechanical force (124) applied on it by the pilot (44), for moving it to meter pressure and flow from a supply pressure (72) to the wheel brakes (34) , or a hydraulic pressure force (128) applied following take-off, to activate the brakes (34) for stopping the wheels from spinning. The valve housing (62) defines an annular command pressure chamber (102) surrounding a portion of the port control member (80). The port control member (80) provides a larger pressure surface (128) to this chamber in the brake applying direction than it does in the opposite direction. This area differential results in pressure within the command pressure chamber (102) acting to move the port control member (80) in a brake applying direction. The command pressure chamber (102) may be connected to the wheel retract system (130) so that pressure is delivered into this chamber (102) automatically at the start of the wheel retraction operation.
