<p>A brake and anti-skid control utilizing optical input sensors (41, 19) for determining wheel speed or position and suitable for aircraft use is disclosed. A valve control (79) has a continuous source (29) of pressurized hydraulic fluid, a hydraulically actuated wheel rotation brake device (13) which responds to applied hydraulic pressure to apply a braking force to the wheel to arrest wheel rotation, a low pressure hydraulic fluid return (33), and a flow control servo valve (17) interconnecting the source (29), the return (33), and the braking device (13) for directing fluid from the source (29) to the braking device (13) when in a first state and for directing fluid from the braking device (13) to the return (3) when in a second state. Applied hydraulic pressure is monitored and if that monitored pressure exceeds a command pressure, further fluid from the braking device (13) is diverted to the return (33).</p> |
