Abstract
A hydraulic circuit for aircraft braking, the circuit including wheel brakes (11) fed with hydraulic fluid by servovalves (8, 22) mounted in a normal circuit and in an emergency circuit. The normal circuit and the emergency circuit are selectively connected to the wheel brakes by switching devices (9) and protected from excessive loss of hydraulic fluid by hydraulic fuses (6, 24). The servovalves of the normal circuit are associated in pairs. The hydraulic fuses (6) of the normal circuit are disposed upstream from the servovalves (8) on lengths of line (5) which are common to each pair of servovalves. The devices (9) for switching from the normal circuit to the emergency circuit are disposed downstream from the servovalves (8).
Claims4
A hydraulic circuit for aircraft braking comprising wheel brakes fed with hydraulic fluid by servovalves mounted in a normal circuit and in an emergency circuit, the normal circuit and the emergency circuit being selectively connectable to the wheel brakes by switching means and being protected from excessive loss of hydraulic fluid by hydraulic fuses;
- wherein the servovalves of the normal circuit are associated in pairs, the hydraulic fuses of the normal circuit are disposed upstream from the servovalves of the normal circuit on lengths of line which are common to the two servovalves in each of said pairs of servovalves, and said means for switching from the normal circuit to the emergency circuit are disposed downstream from the servovalves wherein each servovalve of the emergency circuit is associated with two switching means.
