Electronic Pressure Control Device Supplied To A Railway Brake Caliper

Abstract: ELECTRONIC PRESSURE CONTROL DEVICE SUPPLIED TO A RAILWAY BRAKE CALIPER The invention relates to a device (10) for regulating the pressure supplied to a railway pneumatic cylinder brake caliper (E) via an upper solenoid valve (EV1) for increasing pressure and a lower solenoid valve (EV2) for relieving pressure, and comprising a pressure regulator (12) configured to: - comparing a first signal representative of the pressure measured in said caliper with a second signal representative of a reference pressure, - controlling the opening of the upper solenoid valve when the value of the first signal is lower than that of the second signal, and on the other hand, the opening of lower solenoid valve; in the presence of an emergency braking request, the second signal being representative of the pressure value needed for the emergency braking, in the absence of such a request, said second signal being obtained from a service braking input.
