Braking system for a self-powered rail vehicle provided with an anti-slip device

摘要

A pneumatic operating device for direct braking and an electropneumatic valve unit of an anti-slip device have their outlets connected to the braking actuators through an interlock valve device which can selectively allow the greater of the pressures received from the said devices to pass towards the braking actuators. The electrical operating device for the direct braking is also connected to an electrical interlock device associated with the electrical valve unit of the anti-slip device. When the electrical operating device for the direct braking is operated, the electrical interlock device disables the electrical anti-slip valve unit and makes this unit open with respect to the braking pressure sent towards the braking actuators.
