Fuellventil fuer Druckluftbremsen,insbesondere von Schienenfahrzeugen

摘要

The pressure control valve for the separate reservoirs of the air brakes on the train has a double element valve with the elements joined by a spring. The double arrangement ensures that if the reservoir pressure drops below a set value then the valve opens to a maximum flow rate until a set pressure, after which a controlled filling proceeds. The system ensures that a set minimum pressure is always available in the reservoirs, especially after heavy braking cycles.
