HYDRAULIC BRAKE ARCHITECTURE FOR AIRCRAFT FOR BRAKING AT LEAST ONE WHEEL OF THE AIRCRAFT

Title:

HYDRAULIC BRAKE ARCHITECTURE FOR AIRCRAFT FOR BRAKING AT LEAST ONE WHEEL OF THE AIRCRAFT

Document Type and Number:

Japanese Patent JP2012183995

Kind Code:

A

Abstract:

To provide a novel brake architectures whose leakage is reduced.

An aircraft hydraulic parking architecture includes a brake with a wheel braking hydraulic actuator, a pressure source Alim of high-pressure fluid, and a normal braking hydraulic circuit C1. The aircraft hydraulic parking architecture includes at least pressure control servo valve with a supply port P connected to the pressure source Alim, a return port R, a utilization port U connected to the actuator. The brake architecture further includes a parking hydraulic circuit C2 including a parking brake valve PkBV having an outlet port Ps1 selectively connected either to the pressure source Alim or a low-pressure return circuit CR. The outlet port Ps1 of the parking brake valve PkBV is connected to the return port R of the pressure control servo valve.
