Abstract
A driver circuit for driving a brake having a first orifice adapted to be connected to a pressure source, a second orifice connected to a reservoir, a third orifice receiving a braking setpoint, and a fourth orifice connected to a brake. The driver circuit includes a proportional solenoid valve connected to the first orifice; an on/off solenoid valve connected to the third orifice; and a proportional braking valve provided with an actuator and configured in such a manner as to connect a brake selectively to a pressure source or to a reservoir. The actuator is configured in such a manner as to be driven by the higher of the two pressures delivered by the proportional solenoid valve and delivered by the on/off solenoid valve.
